MidiPaddy release notes

What changed, version by version.

Beta release · August 2026

1.0.0 (4)

B-System (4-row) replaces Linear rows on Mac, providing 43 consecutive chromatic notes and a binding for every visible piano key.
Split hands has correctly aligned upper sharps, and DAW two-row extends both hands across the remaining right-side keys.
Left and Right Arrow change the Studio octave; Down and Up Arrow select the previous or next program in any layout.
Arrow-key shortcuts pause during editing and while sheets are open.
Octave and program controls have larger clickable areas on iPad and Mac; program controls now use down and up arrows.

Both platforms use the same public beta invitation.
