Source: the changelog bundled with the current Android app.
Version 4.38
- New: spoken count-in & cues. Michael counts you in and announces sections and cues such as "Drums in", on every phone in the band.
- A song reads like a chart: tempo, time signature and key on top, and every section a coloured block you tap to edit and drag to move. Build a song in seconds: tap Intro, Verse, Chorus… in playing order, or type its form (I4 V16 C8).
- Play any song from the library in the metronome; it runs through all its sections, with their tempo curves and meter cycles.
- Stage lock: while a set plays, every jump and STOP asks you to hold. A tap opens a song or setlist; the strip on its left gets it ready to play. In Stage settings, choose whether the next song starts instantly, after the bar or after the section.
- Band sync: simultaneous tempo and time signature changes now start on the correct bar boundary, and every phone starts the band and an instant song change on beat 1, over Bluetooth and Ableton Link. In the Play version, band sync over Ableton Link works again.
Version 4.37
- Eight languages: English, Dutch, Spanish, Portuguese, German, French, Italian and Chinese (beta).
- Everyone in the band needs this version: the band follows the leader's tempo curves and time signature changes, over Ableton Link and Bluetooth.
- Sound off: one switch silences the click, count-in and spoken cues in every song; backing tracks keep playing.
- Setlists: prepare a set at a glance, search, sort and drag your setlists, and one Band mode button.
- Play a song straight from the library, without making a setlist.
Version 4.36
- In the chord-sheet viewer, the edge overlay now stays against the screen edge. Its border and glow no longer cover the first letters of the sheet, including in landscape.
- Everyone in the band needs this version. Time signature changes, section changes and instant song switches now land on the same bar line on every phone, also for a musician who joins while the band is already playing. An older version still follows the tempo, but after a time signature change it plays one beat off the leader until the next start. Update all band devices before your next rehearsal or gig.
- After an update, SyncPulse now shows once what is new - like this. You can read it again under Settings, About, What's new.
- The song editor has been redesigned. A song with one tempo shows it straight away; with more sections you get a timeline, rows you tap to edit and quick picks such as Verse and Chorus. A section opens in a panel that saves as you go, with undo afterwards. "Continue after this song" and the count-in now have their own Playback card.
- Taking over a chord sheet lets you tick what to use (title, tempo, key, time signature), merge it into your existing sections by name or replace everything, and see per section what stays, what is new and what the sheet does not mention. A heading such as "Chorus x2" becomes two sections, and a tempo, key or time signature under a heading applies to that section only.
- A chord sheet can now also set how long a section is: a length in the heading such as "Intro (4 bars)", or bar lines | ... | on every line of the section. Tap "Show example" in the chord-sheet info for a sheet you can copy. In the viewer, bar lines are drawn in a muted colour so they no longer read as the letter I, bars with only chords get room, and a tempo from the chord sheet no longer keeps the old decimal.
- Band: a stopped leader's tempo and time signature changes reach the followers straight away. In an open session a leader is told when another phone takes over, with the choice to take the lead back or secure the session. A missing Bluetooth permission shows up as a tappable hint instead of endless searching, and a follower's notification no longer says it follows the band after a stop.
- Band over Bluetooth: a leader who leaves the band now really lets go. Until now the old phone kept its followers attached, so nobody could find the new leader. Followers now switch to the new leader by themselves within seconds, and a follower whose leader suddenly goes silent reconnects on its own.
- The setlist preparation list shows each song's duration and its exact tempo, including tempos with a decimal. Importing into a new setlist now tells you how many songs arrived.
- Tempo steps with a decimal carry over whole numbers correctly, and the tempo buttons no longer shift when the number gets wider.
Version 4.35
- Android Back closes the guide and returns to the previous screen.
- The overlay pill now has a uniform border, without the extra thick line at the top.
- Android Back returns from the active setlist view to the standard metronome screen without stopping playback. Tap Setlist Mode to return to the active set.
- Setlist countdown banners show the remaining bar count only once.
- Long song titles on the podium stay on one line and are truncated with an ellipsis.
- Setlist fixes: chord sheets open automatically when starting from setlist preparation, and replacing a chord sheet keeps the previous file safe until the song is saved. Large Excel imports preserve all exported text, and imports keep tempos below 30 BPM. Malformed band-network fragments are safely rejected.
- SyncPulse has a new logo. The app icon, the start-up screen, the header at the top of the main screen and the icon in your notification bar now show the new metronome mark, with the SyncPulse name drawn in its own typeface instead of plain text. In the light theme the logo switches to the app's darker teal, so it always matches the buttons around it. On Android 13 and later the app icon can also take on your wallpaper colours when themed icons are switched on.
- The contact address in the privacy policy and terms of use is now info@syncpulse.band.
Version 4.34
- Leading a band no longer keeps your device awake between sets. A leader that had stopped playing kept the processor awake for as long as the band session stayed open - exactly the break between two sets, on the one device you need all evening. It now lets go the moment you stop and takes the CPU back when you start. Your followers stay connected throughout: measured over ten minutes with the leader's screen off and the device in deep sleep.
- Over Bluetooth the band now counts in together. The leader used to begin its own count on its very next tick while telling everyone else to start on the coming bar line, so every other phone counted a full bar late and the next musician came in a bar behind. The leader now waits for the bar it broadcasts, like it already did over Ableton Link. Everyone in the band needs this version. On your own over Bluetooth, start can now wait up to one bar before the count begins - that is the same price Link has always paid.
- Queued and automatic section changes finish the outgoing beat, including its subdivisions, before applying a new time signature or count-in. Natural stops and backing-track transitions finish the final beat. The next backing track is prepared while the previous one is still playing.
- Selecting another song while paused updates the title and tempo sent to band followers. Use the current app version on all band devices for aligned natural stops. Manual Stop remains immediate.
- Band followers receive in-song count-ins and the leader's queued next cue. Visual and spoken cues respect pauses between songs and fermatas.
- Band meter changes keep the intended beat over Bluetooth; Link messages also carry the timing grid so a follower can recover after missing an update.
- Names in the old single-preset format survive conversion to sections. Matching names already converted to Room can be recovered once from the retained migration snapshot; new untitled songs stay untitled.
- Export gives untitled songs unique placeholder names even when an existing song uses that name, so re-import does not merge them.
- The beat bars follow the accents of the currently playing meter-cycle step.
- Explicit song-library names are preserved when saving and editing. Ambiguous older "Default" names are kept.
- The song library can be sorted A-Z or by Recently added - the quickest way to find what an import just brought in. Select lets you tick several songs and delete them in one go, and the search field has a button to clear it.
- During a ritardando or accelerando the big BPM number now follows the tempo you hear, updated at every bar line and marked "rit." or "accel.". The section you programmed is left untouched. In a meter cycle the screen shows the meter and the number of beat bars that are actually playing, instead of the section's first meter.
- In a setlist, an automatic change to a new time signature now lands on the next bar line instead of a full bar late.
- Over Ableton Link, a time-signature or tempo change from the band leader now lands on the bar line for followers too, instead of immediately.
- A song without a title no longer shows up as "Default" on the main screen, the overlay, the spoken announcement or a follower's screen.
- Counts read properly in the singular: "1 song" and "1 bar" instead of "1 songs" and "1 bars".
- If the audio output fails during playback, SyncPulse restarts it once and tells you. If it fails again, playback stops with a message instead of silently carrying on without sound.
- Searching for Bluetooth MIDI devices now asks for the Bluetooth permission when it is missing, with a shortcut to the app settings, and shows whether it is still searching, found nothing or failed.
- Android's backup now includes your setlists and song library, not only your settings.
- English and Dutch are both always included when you install from Google Play, so switching the language inside the app works on every device.
Version 4.33
- While you follow the band, your phone now shows what the leader shows. The song and section they are on, and what is coming next, sit under the tempo in the same place and the same size as on the leader's phone, so a glance across the stage tells you both the same thing. The tempo controls are hidden while you follow, because the leader owns the tempo - the beat bars stay full size.
- A phone waiting for the band no longer shows a song it is not being sent. A leader who had stopped, or who had left their setlist, kept broadcasting the last section title, so followers displayed a song that was not playing. Stopping now clears it. The pause between two songs still keeps the title, because there the song really is still the current one.
- Being in a band session no longer keeps your screen awake by itself. Keep screen on now means what it says: the display stays awake while something is actually playing or a setlist is paused, and a phone waiting for the leader sleeps normally and wakes the moment the leader starts. Until now every phone in a session stayed lit for as long as the session lasted with nothing playing, the leader's included.
- The beat bars are about 15% shorter throughout the app.
Version 4.32
- The example workbook behind the info button next to Import works again. Saving it worked, but importing it back always failed with an error - and so did every other Excel (.xlsx) or SetlistMaker (.sml) file. A security setting added to the spreadsheet reader asked the Android XML parser for something it does not support, which made every one of those imports fail before it read a single row. CSV files were never affected.
- Importing a song list into the song library no longer blindly duplicates titles. When a title already exists in the library or occurs more than once in the file, SyncPulse asks what to do with every collision: skip it, replace the earlier version, or add it as "Title (1)".
- The song library can now export its song table as CSV or Excel, in the same interchange format as a setlist. The screen clearly marks this as an export rather than a full backup: backing tracks, PDF/image chord sheets and some app-only settings are not included.
- The song library also got Delete all songs, behind two confirmation screens because there is no undo. Your setlists keep their own copy of every song, so they stay untouched.
- The song library screen itself is clearer: New song and Import are labelled buttons instead of nameless icons, the song count is readable, and the info button now hands you the example file too.
- On the setlist screen the previous/next song arrows moved to either side of the START/STOP button, the same place they have in the chord-sheet view. That frees the whole top block: the song title now gets the full width and two lines instead of a strip squeezed between two buttons, "Next:" sits right under it and is bigger, and the block as a whole is a lot shorter, so more of your set stays in view.
- The glow around the BPM number is gone. It was being clipped at the edges of the block, and on stage the pulsing halo mostly pulled your eye away from the beat bars that carry the same information.
Version 4.31
- The band now counts in together. When the leader presses start, every device begins the count on the same bar line, so you hear one shared 1-2-3-4 instead of one phone starting halfway through a bar and the song landing off the downbeat. Everyone in the band needs this version for it to work - a phone on an older build still counts in on its own.
- Because the count now waits for the shared bar line, there can be up to one bar of silence between pressing start and the first count - that is the price of starting on the band's grid. On your own, without other devices in the session, nothing changes.
- Chord sheets can scroll along with the music. Switch on auto-scroll and a ChordPro sheet moves with the bar you are playing, following the sections of the song rather than a fixed speed. Swipe and it stops dead, without springing back; resume and it returns to where the music actually is. A manual or open-ended section simply waits until you move on. PDFs and photos are unchanged for now, and the whole thing is optional.
- The chord-sheet viewer and the live setlist screen now speak the same language: one title notation ("Section (Title)"), and the performance info sits in a fixed bottom panel instead of floating over your sheet.
- Nothing jumps in above the beat bars during a count-in any more, so the song list stays where it is. While counting in, the section line reads "Count-in: 3" and the line under it points at the section that is about to start.
- Adding a chord sheet now has an info button that spells out what you can drop in - typed or pasted ChordPro, a PDF, or photos of a page.
- Starting a band session over Bluetooth no longer risks two leaders at once. The app listens for a few seconds first and lets you choose if somebody is already leading.
- Big beat bars in a setlist is a new option under Display. While a setlist plays the beat bars stay small so the song list keeps its place; switch this on and they grow while you play, like they do on the metronome screen - a little less tall, and only as far as the screen has room for. Off by default.
Version 4.30
- The play notification now returns you to SyncPulse when tapped and disappears when standalone playback stops. The main screen no longer reserves space for stage setup; an active band connection is shown compactly instead.
- Setlists can now be saved locally as CSV or Excel as well as shared. The import help offers a ready-to-use example Excel file, and song and section editors use a clearer field order with shorter chord-sheet labels.
- Backing tracks and instant song switching now live under Setlists > Performance settings > Playback. Settings cards use consistent spacing, with help available directly on Audio offset and Footswitch.
- Sections can change tempo while they play. Open a section, and under the bar count you can set a closing tempo: the click slows down (ritardando) or speeds up (accelerando) towards the end of the section, and the last beat lands exactly on the tempo you typed. Want the rit. only in the last two bars of the outro? Set it to run over two bars and the rest of the section stays put.
- A section can end on a fermata. Switch it on and the click holds on the last beat until you press play again - overlay, footswitch or the Start button - so the band can hang on a chord and come back in together.
- Odd-meter songs no longer need one section per bar. A meter cycle repeats a sequence of time signatures, one per bar - 7/8 + 4/4, or a 7+7+11 cycle - and the click switches on the bar line. The underlying pulse stays the same, so the eighth note does not change speed when the cycle moves from 7/8 into 4/4.
- All three settings travel with the song: they survive saving, copying into another setlist, and CSV/Excel export and import. In band mode a section still plays its fixed tempo and time signature.
Version 4.29
- Your screen no longer goes dark in the middle of a rehearsal. While the metronome or a setlist is running, the display stays awake instead of hitting your phone's screen time-out and locking. Keep screen on sits under Settings > General and is on by default; stop playing and your phone sleeps as usual.
- Switch songs instantly is a new option under Settings > Controls. Normally a song jump waits for the current bar to finish and then counts you in; with this on, the next or previous song takes effect the moment you press it, at the new tempo, on a fresh downbeat and with no count-in. Section navigation inside a song is unchanged.
- The previous/next song arrows are noticeably bigger while a setlist is running, so you can hit them from behind a kit without aiming.
Version 4.28
- Setlists can be renamed, exported and deleted again. The three-dot button at the end of a setlist row in the Hub brings back all three; they had gone missing when the Hub was simplified.
- Exporting writes your setlist as CSV or Excel and hands it to your usual share sheet, so you can mail it to a bandmate or keep a backup.
- The import button now has an info button next to it that spells out exactly how to lay out a spreadsheet or text file, with a worked example. Plain .txt tables were always accepted; now the app says so.
Version 4.27
- Spreadsheets with your own column names now import too. If SyncPulse does not recognise the headings, it asks which column is the tempo, the time signature and so on, instead of just saying it could not read the file.
Version 4.26
- Click volume above 100% now explains itself. A short line under the control tells you that this range is boost and can add grit or distortion, and screen readers announce the same thing.
- The tempo, volume, overlay opacity and audio offset sliders now save when you let go, instead of on every frame while you drag. On slower phones the thumb no longer springs back to its old value.
- Rotating your tablet, or returning after Android has cleaned up the app in the background, now keeps you on the screen you were on — including an unsaved song edit in the editor.
Version 4.25
- Chord-sheet zoom, panning and the read-only follower view now have device-level regression coverage, reducing the risk of viewer regressions on future Android versions.
- The Google Play presentation has been refreshed to reflect SyncPulse as the complete stage tool it has become: metronome, setlists, chord sheets, backing tracks, band sync and MIDI in one flow.
Version 4.24
- Tighter click timing. Every beat is now placed on its exact output sample instead of being rounded to the start of the next audio buffer. On phones with a large audio buffer that rounding could shift a beat by several milliseconds, and by a different amount each time — the part you could hear as a slightly unsteady click. Measured on a Samsung S20+, the remaining variation is 0.11 ms.
- Exporting a setlist to CSV or Excel now keeps your chord sheets. The sheet text travels in its own column and comes back when you import the file again. Files exported by older versions still import as before.
Version 4.22
- The in-app sheet viewer now keeps performance information and controls in a fixed bottom panel for both leaders and followers, so they never cover the sheet or PDF. The floating pill remains available outside the viewer.
- Band sync protocol upgrade: this version can no longer sync with older SyncPulse builds. Update everyone in the band to this version before you play together — the band panel will tell you if someone hasn't yet.
- Pairing the SyncPulse Device companion now shows the discovered devices and asks you to pick the right one, instead of connecting to whichever one answers first.
Version 4.21
- Pressing forward on the overlay no longer skips a song: one press now moves to the next section, not the one after it.
- Bluetooth sync fixed: a follower could end up receiving nothing at all, because a setlist or chord sheet being sent could push the timing signal out of the queue. The click now always has priority.
- A Bluetooth device that isn't the leader no longer keeps ticking at the tempo of an earlier song.
- The chord-sheet button is always there when the song has a chord sheet — no setting to switch on first. The old switch now means "open the chord sheet as soon as the setlist starts".
- Transposing works per song. If the chord sheet declares a key and the song's first section has one, the sheet is shown in that key, and the +/- buttons move every section of the song by the same amount — so your setlist, the Live screen and the rest of the band all follow. A modulation inside one section belongs in the chord sheet file itself.
- The transpose buttons moved to their own row, away from the next/previous song buttons, and are bigger.
- The setlist settings are reachable again: auto-advance has its own button next to the lock on the Live screen and keeps working with the stage lock on, and the gear beside it opens the Setlist & band hub for the rest.
- While following, the setlist mirror now highlights the section the leader is on, not just the song — and turning the song title off no longer blanks that mirror for the rest of the band.
- Chords no longer disappear behind the lyric under them at smaller text sizes.
Version 4.20
- Band followers can now see the leader's chord sheet, kept in sync automatically as it's picked or edited.
- Chord sheets support display-only transposition — view the sheet in another key without changing the saved sheet.
- Export a chord sheet through the system share sheet, and jump directly to the next or previous song from inside the sheet viewer.
- A dedicated Sheet music section in the setlist Hub, with an on/off switch for the live chord-sheet entry and a text-size slider with a live preview.
- The in-app sheet viewer now shows your actual configured metronome overlay (dot, pill, bars, ...) instead of a generic indicator, with a landscape-first layout that hides its chrome automatically.
- A leader's transpose is now shared with the band and shown to followers automatically.
- The in-app overlay no longer appears in the wrong spot when you first open the chord-sheet viewer.
- The chord-sheet viewer always shows page-turn arrows for a multi-page PDF, even without zooming in.
- Closing the chord-sheet text editor with unsaved changes now asks for confirmation, and a half-typed sheet survives a screen rotation.
Version 4.19
- Chord sheets: attach a chord sheet to any song in the setlist editor — paste/type a ChordPro-style chord sheet, or pick a PDF or one or more photos of a page.
- Pasted chord-sheet text reflows to any screen size and adjustable font size, with the chord staying above the right syllable.
- View a song's chord sheet fullscreen from the Live screen, with tempo/beat/section always visible and start/stop and section jumps without leaving the sheet — the screen stays on while it's open, and it switches automatically at a song change.
- PDF and photo chord sheets support pinch-to-zoom, panning, and swipe to turn pages.
- Importing an OnSong file (or a songbook ZIP of them) now also brings along the chord sheet text itself, not just the title/tempo/time signature.
Version 4.18
- Updated to support Android 16.
- USB audio interfaces now keep their own audio-offset calibration instead of sharing it with wired headphones, so a latency you measure on a USB interface is applied correctly.
- The tap-test no longer counts two taps against the same click, for a more accurate measured audio offset.
- Backing tracks with a start delay now begin more precisely on the beat.
- Various reliability and performance improvements under the hood.
Version 4.16
- A backing track with a delayed start no longer plays after you've already stopped or switched to another song.
- The compound-meter toggle in the section editor no longer silently turns itself back on when you reopen a section you'd deliberately switched it off for.
- The Wi-Fi setup dialog for the SyncPulse Device companion can no longer get stuck — Cancel now always works, and a stalled connection now times out instead of hanging forever.
- Importing a setlist (CSV/Excel) now asks whether to create a new setlist or add the songs to the current one, instead of always adding to whichever setlist happened to be open.
- Song notes in the setlist editor can now span multiple lines instead of being cut off after one.
- The setlist editor shows your position among the songs (e.g. "12 / 37").
- Tapping a locked control while the stage lock is on now shows a brief message instead of silently doing nothing.
Version 4.15
- Swiping the app away while band mode is active now properly stops the metronome and removes its notification, instead of leaving it running in the background.
- The count-in is no longer occasionally skipped on the very first setlist start right after opening the app.
- Jumping or tapping to a song section now applies that section's own click sound, just like automatically advancing through the setlist already did.
- Band sync over Bluetooth: a follower joining a session now immediately adopts the leader's current tempo and settings instead of briefly waiting for the next update.
- Band sync over Wi-Fi no longer drops updates for songs with long notes.
Version 4.14
- Fixed a brief flash of the floating overlay when starting the metronome while "show overlay in app" is turned off.
- On the main screen, the beat bars now grow to their full, prominent size whenever no overlay is shown over the app — not only when the overlay is set to "Off".
- The tempo trainer's "start from a fixed tempo" now actually sets the BPM to your chosen start value when you press play.
- You can now start a plain metronome without granting the "draw over other apps" permission — it's only requested when you actually use a floating overlay.
- Count-in lengths of 4 and 8 bars are now selectable (they previously snapped back to 1 and 2).
- Fixed distortion on loud cowbell accents.
- Footswitch tap tempo now sets the correct tempo in x/8, x/2 and grouped meters (it previously halved or doubled it).
- Exporting and re-importing a setlist (CSV/Excel) now keeps compound meters, beat groupings, tuplet time signatures and decimal BPM.
- Improved screen-reader (TalkBack) labels across the setlist, live and editor screens.
- Added this changelog so you can see what changed in each update.
