Feature 01

MIDI Learn, just added.

Virtually every knob and slider in TWEAKER can be MIDI-learned via right-click. There’s a new global master pitch wheel parked next to the virtual keyboard — MIDI-learnable too. The main Pitch Slider picked up Pitch Wheel assignment and MIDI Learn as well.

Feature 04

Results List goes virtual.

The Results List is now fully virtualized — the record limit is effectively gone unless you’re trying to search your entire DB at once. Paging arrived as an option, sorting priority is remembered between sessions, and a gang of optimizations landed underneath.

  • VirtualizedRecord limit removed
  • PagingNew, optional
  • SortPriority recalled on next launch
  • UnderneathOptimizations across the panel

Also new in TWEAKER this month

  • Instant sound on launch — hear TWEAKER immediately, no need to play a Results List record first (improved startup triggering & default-preset loading on macOS)

  • Better voice handling and raised reverse-stream polyphony — fixes a Ping-Pong mode issue
  • MIDI 2.0 / Loopback install instructions added inside the MIDI input dropdown (Windows + macOS)

And, more under the surface

  • Presets — fresh content, organization, recall
  • Filter — improvements across the board

  • And a ton of other improvements tucked away throughout
