- Scale/root filtering on the Toolbox audition keyboards, matching the tracker
punch-in keyboard: out-of-scale keys are dimmed and inert (Chromatic = all
playable). StackedKeyboard now filters in both punch-in and audition mode,
and SlotAuditionKeyboard (synth / SF2 editors) gained the same filter.
- Sampler editor restructured so the 16-pad grid is pinned at the bottom at the
same height the audition keyboards use, consistent across every instrument
editor. The per-pad volume faders moved to a second swipe page (waveform on
page 1, volumes on page 2, with dot pagination), and pad cells now fill the
pinned region instead of a fixed 46dp. Selected-pad state is hoisted into
ParamEditor so the detail area and the pinned grid stay in sync.
Verified on-device: audition keyboard dims to F harmonic minor; sampler pads
fill the pinned bottom region with volumes on the swipe page.
