Tabber Studio release notes

macOS 0.3.16

Your own shortcuts, GP5 tab keys and REAPER's S

macOS 0.3.16, 6 November 2026, build 8b901774

Choose whose keyboard shortcuts Tabber uses: its own (the default), Ableton Live's, Logic Pro's or REAPER's, in Get Started or Preferences > Editing > Keys. Each set adds that app's own Mac keys for the commands Tabber has, for example F9 to record and ⌘T for a new audio track in the Ableton set, and the Tab view keeps its GP5 note keys in every set. S splits clips at the cursor, as in REAPER: the selected clips, or every clip under the cursor, tab, MIDI and audio alike, in one undo step, in Arrange and in the split view. Edit > Keyboard Shortcuts finds a command by pressing its key and prints the set's keys, and the command palette shows the chosen set's key first. The Piano Roll and the Tab view get Arrange's scroll bars with arrows and zoom buttons. + and − now change a note's length the way GP5 does (+ shorter, − longer), with a preference to swap them back. Fixed: on a Swedish keyboard the tab editors' triplet, palm mute and semitone keys work, and Find / Replace is ⌥⌘F on the Mac, where ⌘H hides the app.

macOS 0.3.15

Zoom from the whole song down to single samples

macOS 0.3.15, 6 November 2026, build 56cfd6a1

Arrange zooms out until the whole song fits on screen, however long it is, and far out each track is drawn as one clean waveform, so it stays smooth: a song cut into 3,770 clips redraws in about 4 ms instead of 80 to 95. It also zooms in much further, down to single samples: past the waveform's usual detail a clip shows its real samples, and at the closest zoom each sample is a dot joined by lines. Arrange's scroll bars are always shown, with arrows at both ends and + and − zoom buttons beside them: the bottom ones zoom time, the side ones make the tracks taller or shorter, and each button's tooltip shows its shortcut, ⌘ + scroll for time and the new ⇧⌘ + scroll for track height. Fixed: a track added while the song plays (tab, MIDI or drums), and the notes you write into it, are heard at once. Before, nothing sounded until Stop and Play. The waveform of a long audio file is drawn where the audio plays. Before, near the end of a 4 to 5 minute file it was drawn up to about a second away from the sound, so a cut placed by the waveform landed in the wrong spot.

macOS 0.3.14

Songs open where you left them, and a lighter Tabber Amp

macOS 0.3.14, 6 November 2026, build 362f39e8

Fixes to 0.3.12. A project opens in the view you saved it in, Arrange, Piano Roll, Tab or Split, and a song with only audio tracks opens in Arrange instead of asking you to create a first part in the Tab view. The first track in a new, empty project is 50 bars long instead of 10. Adding, deleting or moving a track while a song plays keeps every track's sound: before, the tracks below it played through their neighbours' plug-ins, faders and sends until playback was started again. + Add Track stays in view in a long track list. Tabber Amp uses about half the processor and sounds the same, a song with it no longer waits about 2 seconds for the first Amp when it opens, and silence in gives true silence out, so the plug-ins after it can rest. To update the Amp, double-click Install Plug-ins in the disk image again.

macOS 0.3.12

Recordings that survive a crash, and plug-in timing fixes

macOS 0.3.12, 5 November 2026, build 572cb993

Fixes to 0.3.11. An audio take that was recording when Tabber closed unexpectedly is kept: the next time Tabber opens, it offers to put the take back on its track where you recorded it, and opens the song first if needed. MIDI recordings are not kept yet. When a song opens, the plug-ins on the selected track and on the tracks that play next load first, so Play gives sound sooner, and the waveforms and the mixer appear in about half the time. An audio file at another sample rate than the session plays cleanly, AIFF files read three to four times faster, and with playback stopped, plug-ins that hear only silence no longer use the processor. Plug-in delay compensation is right in more cases: monitoring a live input is no longer delayed by other tracks' plug-ins, automation on a plug-in after one that adds delay lines up with its audio, a plug-in that fails no longer makes its track play early, a plug-in changing its delay while playing no longer silences the mix, and a CLAP plug-in that asks to be restarted is restarted. An edit you make while the chat is working is its own undo step, and a web page in your browser can no longer send commands to Tabber.

macOS 0.3.11

Much less memory for songs with long audio files

macOS 0.3.11, 5 November 2026, build 4bf3f767

Fixes to 0.3.10. Tabber reads WAV and AIFF files of 30 seconds or more from the disk while it plays, a little ahead of the playhead, instead of holding every file whole in memory: a song of 23 stems took about 1.3 GB while playing and now takes under 0.5 GB. This applies to files on the Mac's internal disk and other solid-state disks; shorter files, MP3 and FLAC files, and files on other disks are held in memory as before, and bounces sound exactly the same. Pressing Play right after opening such a song starts at once; before, Play waited for the files still being read. Zooming out and scrolling the Arrange view of a song with many audio clips is smooth: a song split into a few thousand clips took about 70 ms to redraw when zoomed out and now takes about 20 ms. A loop set through the chat or the Control API stays set when the playhead moves or Play is pressed, also in a song with only audio tracks.

macOS 0.3.10

Up to 500 tracks, and faster, lighter songs with audio

macOS 0.3.10, 4 November 2026, build 495f253f

Fixes to 0.3.6. A project can have up to 500 tracks; before, every track after the 64th was silent without a warning, and a saved project with more than 64 tracks could not be opened again. In a song with audio files, Play starts at once: Tabber reads the files in the background as soon as the song opens, and a Play pressed before that has finished waits only for the files still being read; before, the first Play read every file whole with the window frozen, about a second for a song of 23 stems. That audio's memory is now in use from the moment the song opens. Songs with many audio files use less memory (the waveforms of 23 stems took about 400 MB and now take about 40 MB, and splitting clips no longer makes memory grow without limit), the window no longer freezes while their waveforms are drawn, scrolling the Arrange view redraws only what comes into view, and zooming a song split into a few thousand clips no longer stops the window at every step. MP3 files play in time; before, an MP3 started about 50 ms late. A project plays at the master volume it was saved with; before, it played at 0 dB until you moved the master fader. An audio file imported onto a new track plays through that track's channel; before, it went straight to the master, so the track's fader, mute, solo, effects and meter did nothing to it.

macOS 0.3.6

The mixer shows a project's plug-ins at once

macOS 0.3.6, 3 November 2026, build 29f737ce

Fix to 0.3.5: after opening a project, the mixer lists every strip's plug-ins straight away, and its meters run while stopped. Before, the plug-in lists stayed empty until you pressed Play or inserted a plug-in, although the plug-ins were loaded and working.

macOS 0.3.5

Text that fits: mixer plug-ins, track names and dropdowns

macOS 0.3.5, 3 November 2026, build 50b2e4e2

Fixes to 0.3.4 on the Mac. In the mixer, a strip with several plug-ins shows each one in full; before, each plug-in's row covered the lower half of the one above it. In the Tab view's Tracks panel, an audio track's name has room, with the input button on the Audio line, and the buttons on every track line up; before, a name like 01_AcousticGtr showed as 01_…. Dropdown lists are readable, such as the Track ducking dialog's Starting point; before, they showed light text on a light background.

macOS 0.3.4

AIFF import, and a new sound heard at once

macOS 0.3.4, 2 November 2026, build 68d30392

New: AIFF files import. Import Audio File and drag-and-drop now take .aif, .aiff and .aifc files, the default export of Logic and GarageBand, and they play exactly like the same audio as WAV. Fixes to 0.3.3: a new sound chosen for a MIDI track is heard at once, while the song plays and when you play a keyboard through the track; before, the old sound stayed until you pressed Play, and the switch makes no gap. A keyboard played through a MIDI track is heard from the first key, also on a new track, on a track whose notes the song has not reached yet, and after a bounce or export; before, such a track stayed silent until playback reached one of its notes. An audio file imported while Tab view shows appears there at once; before, it showed only after switching to another view and back.

macOS 0.3.3

Ducking window and piano keyboard fixes

macOS 0.3.3, 2 November 2026, build 647b5467

Fixes to 0.3.2. In Tabber EQ's window, the Ducking button now opens its window in front; before, it opened behind the plug-in window and behind the mixer. With the fretboard open when Tabber last quit, showing the piano keyboard now gives it half the row beside the fretboard; before, only a narrow sliver of the piano showed until both panels were closed and opened again.

macOS 0.3.2

Playhead and bus meter fixes

macOS 0.3.2, 31 October 2026, build 675f2343

Fixes to 0.3.1. In a project with only audio tracks, the playhead and the bar and beat display now move during playback; before, they stayed at the start while the audio played. After New Project or opening a project, a new bus shows its own level in the mixer; before, the previous project's buses stayed in the audio engine and a new bus's meter could show an old, silent bus instead.

macOS 0.3.1
