KeyPad MIDI Controller

MPE pitch bend now broadcasts to all member channels, so notes you're already holding bend correctly instead of staying fixed. Added a Big Piano grid view with refined sharp corners and cleaner natural-key labels. Grid layouts are now a radio group in the View menu, and a new scale remap mode plus piano sharp shift give you more ways to lay out the keyboard. Key Width moved into the View menu as its own group for consistency. Added a minor-thirds grid mode (columns step up by 3 semitones, rows go chromatic). Double-tapping SUSTAIN (or tapping it with two fingers) now latches it on, with a red border and held-key lighting; a single tap releases the lock. MPE sustain broadcasts CC64 across all member channels so held notes sustain reliably. Fixed grid slide velocity to keep the original strike velocity instead of re-reading at the cell edge. Grid MPE output is now deduplicated for parity with the piano, and MPE pitch-bend stepping is smoother thanks to non-blocking MIDI output and deduplication.

Major overhaul of MPE. All per-note expression settings now live in a dedicated MPE menu with a single toggle to enable it. Aftertouch and MPE are mutually exclusive, keeping the controls clean. The vertical axis to Up only (CC74, the new default), Up/Down (CC74), or Down only (Aftertouch/Z), and assign the horizontal axis to Pitch Bend with a selectable range (2 to 96 semitones), a MIDI CC of your choice, or off entirely. MPE now behaves like a proper MPE controller. Pressing a key no longer jumps the timbre or filter value — expression starts centered and responds to how you slide from the touch point, matching hardware like Seaboard and LinnStrument. Pitch bend on the piano is now smooth and continuous instead of stepped, scaled to the chosen range, and expression responds immediately on press with no delay. Key lighting updates correctly while pressing and holding, sliding down in "Up only" mode no longer changes the key color, and remapped horizontal CCs sweep their full range across the key. Under the hood, MPE setup messages are now spec-compliant for better compatibility across synths, CC74 is centered on note-on with expression values reset cleanly on release, and all MPE settings are saved and restored between sessions.

Added an isomorphic grid view with single-row and 2-row piano layouts, dedicated mod-wheel cells, MPE per-note expression, pitch bend, a vibrant gradient colour scheme, optional note labels, and persistent view, layout, and root note. Added persistent Remap Mod Wheel CC option and fixed velocity menu options (127/100/64/32) that disable the fader. Improved the 3D wheel gradient curvature and cleaned up menus by hiding unavailable options.

Added Bliss Sampler ZBP/ZBB preset and bank format support. Added velocity-based key color saturation in height-based velocity mode. Pressed keys visually reflect velocity intensity when height-based velocity is active, composing naturally with aftertouch feedback. Fixed issue causing silent notes at low velocities.
