MultitrackStudio for iPad

June 27, 2024

• MultitrackStudio Instruments 2.0. Almost all instruments sound better, with a special mention to the acoustic pianos. Acoustic pianos, Harpsichord and Harp have a Width knob and better stereo sound. Acoustic pianos support Sostenuto pedal, Soft pedal is now continuous rather than on/off. New Upright Piano. Honky Tonk Piano now really is honky tonk. Drum Kit is panned stereo and has a Width knob. Drum Kit, Timpani and Synth Drum can be panned using per-note pan controllers. • The MultitrackStudio Instruments support some articulations for Overdrive Guitar / Distortion Guitar (Normal, Muted, Harmonic), Electric Bass (finger) (Normal, Slap), and Violin/Viola/Cello/Contrabass (Bowed, Pizzicato). • You can define articulation selection keys in the Keyboard Mapper, so you can easily play articulations live. • 'Make monophonic' option in Keyboard Mapper. • MultitrackStudio now tries to avoid losing the MIDI 2.0 note attribute in AU MIDI effect plugins which don't support MIDI 2.0. The note attribute is used for articulations. • Higher math accuracy in many audio effects. • Rotor effect: improved speed up/down timing. • Guitar Amp effect uses higher oversampling rate (8x). • Velocity Curve (MIDI Effect): Curve knob now works the other way round. The range has been extended from 0.5..2 to 0.33..3. • MIDI editors handle per-note controllers smarter when adding new notes, so the new note fits in better. • Drum note names appear in controller editor for per-note controllers. • You can now type MIDI note numbers (0..127) in text boxes that accept notes (like C#5 etc). • Fixed: transport buttons work again after hiding the keyboard in the Lyrics/Chords editor. • Fixed: EQ: the spectrum value displayed for the current mouse position wasn't correct for 'No Bands'. • Several other fixes.

• Effect, Instrument and MIDI Effect panes: you can swipe up/down over the Presets button to move to the next/previous preset. • External MIDI Instrument: swiping up/down over the Patch box now steps through the patches in the order you see in the Patch Selector. It used to control the MIDI program directly. • Newly recorded audio tracks align better with existing tracks. • The articulation settings from the Note Editor are now available in the Multi Note Editor too. • 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. • MIDI Pattern Editor: horizontal scale is automatically adjusted to a reasonable value if the main editors are zoomed out quite a bit. • Fixed: Bypassed MIDI Effect plugins were no longer bypassed after re-opening the song. • Fixed: several dialogs could freeze on some 2017 iPad Pro models. • Several other fixes.

• Fixed: there could be glitches in audio recordings using the built-in mic of some iPad models.

• Uses MIDI-CI to retrieve program names and controller names from the MIDI Output Device. MIDI-CI is part of MIDI 2.0. Works with USB MIDI 2.0 class compliant devices (requires iPadOS 17). • Can import .midi2 files (MIDI 2.0 Clip File). • Fixed: Pro Extension price could take a long time to appear.

• Fixed: USB audio devices didn't work with iPadOS 17.

• 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. The controller editor's Dot Editor accepts values like 60.9. • MIDI 2.0: the new RPN 7 (per-note pitchbend sensitivity) is sent to MIDI Out Device and AU plugins that support the MIDI 2.0 protocol. • AU plugins: MIDI output can be MIDI 2.0 (requires iPadOS 16). • Matrix Sampler supports pan MIDI controller and per-note aftertouch ('poly aftertouch'). Also supports MIDI 2.0 per-note volume, pan and expression. • MIDI Controller editor: the controller selector menu now lists the controllers that are actually supported by the track's current MIDI instrument. This isn't possible for External MIDI Instruments and plugins, some widely supported controllers appear instead for those. The 'Other' submenu is now 'All', and contains all controllers. • 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. • Note Velocity editor now tries to keep the vertical bars within in the measure the note's in. The vertical bars will be narrower for measures with many notes. This works better, especially with Pencil or mouse. • MIDI controller editor / Automated Fader / Automation editor (Pro Extension) 'draw' mode: the first bit you draw is now predictably smooth. • Multi MIDI Editor: the score view now has a System Spacing setting (tap a clef on the left to access it). Also, the system spacing now takes the actual notes into account. As a result you can see more systems simultaneously. • 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. • Keyboard Mapper can now convert incoming controllers to NRPN. • PatchMap files can define names for MIDI channels. They appear in the External MIDI Instrument channel selector dropdown menu. • External MIDI Instrument: swiping over the patch name box vertically increases/decreases the MIDI program number. • Fixed: Clicking with mouse or Apple Pencil to unselect could accidentally select a dot in MIDI controller editor / Automated Fader / Automation editor (Pro Extension). • Fixed: 'Import Song' could cause an error. • Fixed: audio track editor could cause error for a stereo track if a mono audio playback device was used.

• Fixed: Onscreen keyboard Fourths and string layouts didn't work on iPad Mini.

February 20, 2023

• Onscreen keyboard supports presets. • Onscreen keyboard features new 'Fourths' layout. Has 8 rows of cells, supports Glide and supports playing multiple notes on a single row. • Onscreen keyboard Guitar, Bass and Violin layouts now support Glide (optionally). • Automation Recording for AU plugins (Pro Extension). • EQ: preset menu items show a small version of the curve you see in the EQ window. • MultitrackStudio Instruments: Sine Wave instrument now responds to polyphonic aftertouch. • Grid bars (above the editors) now show markers names instead of just a triangle. • Fixed: MIDI "poly mode" controller messages were sent instead of "all notes off". • Fixed: an error could occur if you tapped the 'MIDI Keyboard' button multiple times while an AU plugin was loading.

• Fixed: Document Picker didn't work in iPadOS 16.

• New Poly Modulator MIDI effect. • New Velocity Curve MIDI Effect. • Automation editors (Pro Extension), MIDI controller editors and Automated Fader effects: the Dots Editor window that pops up on clicking EDIT when multiple dots are selected can now generate Square waves. The Triangle option now has a Shape slider that can turn the triangle into a sawtooth. • Audio effects no longer emit old reverb tails etc. when the effect is un-bypassed. • Note Velocity Editor: with the Drum editor you can now make just a single instrument appear in the Note Velocity Editor by clicking an instrument name on the left (so it's highlighted). • Onscreen Midi Keyboard now keeps AU plugin loaded if you hide the keyboard, so it's immediately available when you open the keyboard again. • MIDI effects: 'Apply to track' option can now generate MIDI controllers etc. (it used to do notes only). • 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. • Remote Control for transport ("MIDI Learn"). (requires Pro Extension) • iPadOS 16: layout takes Stage Manager's multitasking handle into account. • Fixed: Plugin Manager category selector menus didn't fit the screen if the number of categories was very high. • Fixed: issue with saving/loading MIDI patterns.
