MultitrackStudio version history

Release 10.8 (January 24, 2024): (read more)

New:

Samplerate conversion is applied behind the scenes if a song uses a samplerate which isn't supported by the audio device(s). (Mac, and "Windows" driver type on Windows)
"Windows" audio driver type: Automatically uses shared mode if exclusive mode isn't available. Newly recorded audio tracks align better with existing tracks. Soft Monitoring latency is a bit lower.
Effect, Instrument and MIDI Effect windows: there are now up/down arrows next to the Presets button. You can click them to step through the presets without opening the presets menu.
"Mute click track during playback" option in Preferences window.
The articulation settings from the Note Editor are now available in the Multi Note Editor too.

Improved:

External MIDI Instrument: the up/down keys now step through the patches in the order you see in the Patch Selector. They used to control the MIDI program directly.
MIDI Pattern Editor: horizontal scale is automatically adjusted to a reasonable value if the main editors are zoomed out quite a bit.
EQ: spectrum display works if EQ is visible and transport isn't running, even if neither the track's Rec button nor Soft Monitoring are enabled. Just like the Tuner.
CLAP plugin scanning is more robust.
Windows: VST3 plugin loading/unloading is more robust.
"Export song" is more robust.
"Windows" driver type: unplugging audio device is handled better.

Fixed:

Bypassed MIDI Effect plugins were no longer bypassed after re-opening the song.
Noise shaping was applied to 16 bit mixdowns even if you turned this option off.
Sidechain input issue with some VST3 instrument plugins.
Mac: file save dialogs wouldn't let you change file format in recent macOS versions.
Issue with drum instrument selector in Multi MIDI Editor.
Issue with text edit box for renaming tracks or labels. (Mac)
LV2 plugin support has been disabled. It needed some work, but the small number of plugins available for Mac/Windows doesn't justify spending more time on this.

Various other improvements and fixes.

Release 10.7 (September 26, 2023): (read more)

New:

Mac: Uses MIDI-CI to retrieve program names and controller names from MIDI Out Device 1. MIDI-CI is part of MIDI 2.0. Works with USB MIDI 2.0 class compliant devices (requires macOS 14).
Can import .midi2 files (MIDI 2.0 Clip File).
MIDI Multi Effect.
Effect windows: S+Left/Right Arrow key closes current window and opens the first slot on the left/right that isn't empty. Works in Mixer Sections, and also in the Multi Effect etc.

Improved:

Sampler: improved .dls importing. On Windows you can now import the system MIDI bank (see the manual).
Note Velocity editor now tries to keep the vertical bars within the measure the note's in. The vertical bars will be narrower for measures with many notes.
MIDI 2.0: the new RPN 7 (per-note pitchbend sensitivity) is sent to MIDI Out Devices and AU / CLAP / LV2 plugins that support the MIDI 2.0 protocol.
VST3 plugins: MIDI controller info (names and which ones are supported) from plugin is used if it looks like the plugin implements this correctly.
Windows: Multi MIDI Editor doesn't have OK button for score view, so there's a bit more room for the score.
Windows: Multi MIDI Editor window appears a little bit taller, so it fills the available space.
Windows touchscreen: Note Velocity editor indicates which note you're pressing immediately, so you can see it without having to wait for the mode selector to pop up.
Windows touchscreen: MIDI controller editor / Automated Fader / Automation editor (Pro edition) 'draw' mode: the first bit you draw is now predictably smooth.
Windows touchscreen: External MIDI Instrument: swiping over the patch name box vertically increases/decreases the MIDI program number.

Fixed:

MIDI controller editor / Automated Fader / Automation editor (Pro edition): clicking to unselect could accidentally select a dot.
VST3 plugins: some plugins containing an editor would keep their position needle moving while the transport was stopped.

Release 10.6.1, Mac only (September 6, 2023):

Fixed:

Fixed several significant graphics issues with macOS 14 (Sonoma) betas.

Release 10.6 (May 23, 2023):

New:

Remote Controls work better with effects/instruments. Pages of controls have better layouts. 'Find on Remote Control' option on rightclick menus of controls.
MIDI Controller editor 'view' menu: 'Other' submenu is now 'All', and contains all controllers, including the ones in the VIEW menu itself. This makes finding controllers using the search box easier.
Automation Editor VIEW menu (Pro edition): parameters now always appear in the VIEW menu itself (no submenu).
AU plugins: MIDI output can be MIDI 2.0 (requires macOS 13).
CLAP plugins: Preset menu now lists the plugin's own presets.
VST3 instrument plugins: note names defined by plugin appear in Drum Editor.
MultitrackStudio Instruments: Sine Wave instrument now responds to polyphonic aftertouch.

Multi MIDI Editor: the score view now has a System Spacing setting (click a clef on the left to access it).
Multi MIDI Editor now simply remembers the state of the 3 editor mode buttons in the bottom left corner (it tried to be smart instead until now).
The MIDI 2.0 resolutions (16 bits for velocity, 32 bits for controllers etc.) are now preserved in MIDI files used in tracks. The high resolutions do not appear in exported MIDI files. NRPN parameters are used for this, similar to how MultitrackStudio stores per-note controllers in MIDI 1.0 files.
MIDI values that are 7 bits in MIDI 1.0 are now displayed with one decimal place, unless the decimal is zero (60.9, 61, 61.1 etc.). This applies to note velocities, controller values, aftertouch etc.
You can rightclick a Note Editor window's Velocity fader and choose Type Value to enter values like 60.9. The controller editor's Dot Editor accepts values like 60.9.
PatchMap files can define names for MIDI channels. They appear in the External MIDI Instrument window channel selector dropdown menu.
Onscreen MIDI Keyboard: Matrix layout pads display note names. The names depend on the MIDI instrument that's responding to the keyboard. The Keyboard Mapper is taken into account.
Onscreen MIDI Keyboard: Slider menu controller names depend on the MIDI instrument that's responding to the keyboard. Controllers that are actually supported appear bold.
Onscreen MIDI Keyboard: Presets and Layout menus now have icons.
Onscreen MIDI Keyboard: Supports presets.
Onscreen MIDI Keyboard: New 'Fourths' layout. Has 8 rows of cells, supports Glide and supports playing multiple notes on a single row.
Onscreen MIDI Keyboard: Guitar, Bass and Violin layouts now (optionally) support Glide.
Onscreen MIDI Keyboard (Mac): added 'Finger Vibrato' and 'Use per note pitch bend'.
When a song is saved for the first time the program settings are now saved too, so the song will still appear at the bottom of the Song menu even if MultitrackStudio crashes.

Fixed:

MIDI "poly mode" controller messages were sent instead of "all notes off".
Remote Control didn't handle certain incoming note-off MIDI messages correctly.
MultitrackStudio Remote preset didn't map the Add Group/Add Effect Return actions.
Error could occur on closing Master section audio view using the X on the left (using the Desktop layout).

Various other improvements and fixes.

Sampler: importing .exs files works significantly better. On Mac .caf files are now supported, including consolidated ones.
Remote Control: MIDI device selectors are now in the Remote Control window itself.
CLAP plugins: supports a few new draft extensions.

Fixed:

Mac: ARA didn't work on M1 Mac (unless running in Rosetta).
Mac: Sampler's Loop Editor display showed no data.
Un-bypassing Saturator effect could cause exception error.
Issue with saving/loading MIDI patterns.

Some other fixes.

MIDI effects: 'Apply to track' option can now generate MIDI controllers etc. (it used to do notes only).
Mac: AU plugins can now receive MIDI 2.0 protocol messages (requires macOS 12).
MultitrackStudio Instruments: synths have a MIDI effect slot. Some sounds use a Poly Modulator.
MultitrackStudio Instruments: synths respond to MIDI 2.0 per-note Timbre controllers (controls Resonance).
MultitrackStudio Instruments: synths respond to MIDI 2.0 per-note Attack and Decay controllers (values at start of note count).
MultitrackStudio Instruments respond to MIDI 2.0 per-note Release Time controller (value at note-off time counts).
MultitrackStudio Instruments: Electric pianos respond to note-off velocity.

When the song is back on the original device you can load the substitute using the instrument/MIDI effect's options menu. Not available for External MIDI Instruments.
.midi and .kar files can be imported, pasted or dropped.

Improved:

There's now just one message dialog if multiple plugins are missing while loading a song. Also applies to SoundFonts for the Mac version's SoundFont Player.

Help/manual layout and image quality improvements.
Mac: help viewer table-of-contents button is now enabled.
Mac: Onscreen MIDI Keyboard in macOS 10.13 and older: the keyboard shortcuts which were missing since version 9.4 now do appear after the corresponding computer keyboard key has been pressed.

Some other improvements and fixes.

Release 9.2 (Feb 14, 2019): (read more)

New/Improved:

Audio/MIDI editors: 'edit controls' (the windows that appear on clicking an EDIT button) now work live. Any changes you make are applied immediately, so the result is visible (and audible if transport is running). The Apply button is removed, you can of course use the editor's Undo button if necessary. There are several other 'edit control'-related improvements.
Note velocity editor: mouse moves are now applied immediately, so you can hear the result before releasing the mouse button.

The Devices window, with the 'Select Devices' button, is removed. You now go straight to the former 'Select Devices' window. The info that was displayed in the Devices window now appears on hovering the Devices menu item.
Windows 10: a helpful message appears if audio recording isn't possible because of Windows privacy settings.
Master Limiter / Noise Gate: histogram 'curtain' movements can be recorded as automation (Pro edition).
External MIDI Instrument windows: Patchmap selection is moved to options menu ('hamburger' button). The default patchmap can be selected there as well (it was in the MIDI Out Options window).
