  1. v1.1.01.1.0Latest2 files

    New

    • FX Para 1, FX Para 2 and FX Para 3: modulation destinations that move the three settings of a Sound's effect, such as a Chorus's Speed, a Delay's Feedback or an effect's Mix. Overdrive's Amp Type ignores FX Para 3. The note played last sets them. On release 1.0.0, a Sound that uses them moves the warp amounts of other voices instead, which is heard only when those voices' Sounds have a warp on.
    • The FX Sounds: 16 bass Sounds that play their effect from velocity, key, clock LFOs, pressure and the wheel, four of them arpeggios. The Tallent Edition Sounds now fill B049 to B128.

    Changed

    • MPE: Y is CC 74 alone, as the MPE specification sets it. The [MPE] page no longer chooses a second controller for Y.

    Fixed

    • Microwave II: the effects no longer freeze the sound or distort the warps. A Microwave II (Board #1 on the Version page) plays 8 voices and has no X-Mod or Warp; their pages are hidden, and their MIDI controllers do nothing. Thanks to @nickb808-dev for reporting it (#1) and testing the fixes on a Microwave II.
    • Microwave II: the modulation destination menu leaves out W1 Warp and W2 Warp.
    • The modulation Destination dial reaches every destination after a Multi has been loaded.
    • Multi mode: the Multi keeps its name and part settings while notes play.
    • MPE: when Manager pressure, Y or bend pushes a note to its limit and then returns, the note goes back to its own Member value instead of below it.
  2. v1.0.01.0.02 files

    New

    • Oscillator 2's wavetable: Osc2 can play a wavetable of its own.
    • X-Mod: phase and amplitude modulation alongside FM, in either direction.
    • Warp: nine ways to reshape each oscillator's wave, with W1 Warp and W2 Warp as modulation destinations.
    • Honda Aliasing: two Aliasing settings that follow the Piston Honda Mk II.
    • Interpolation: the wave position glides between waves, as on the E352 and the Piston Honda, with Startwave Fine in hundredths of a wave.
    • MPE input with per-note pitch bend, pressure and Y.
    • MIDI controllers for every new setting.
    • The Tallent Edition Sounds: 60 Sounds and nine wavetables.

    Changed

    • An XT with the 30-voice expansion plays 25 voices.
    • The demo song and the power-up front-panel test are removed.
