  1. v2.0v2.0: seventeen effects, stereo and a looperLatest18 files

    v2.0: seventeen effects, stereo and a looper

    Made alongside MIDISTOMP v2.0. Every effect also works on stock firmware.

    New effects

    • GRDLOOP: a looper that records whole bars on the song grid. On MIDISTOMP v2.0 up to about 24 s stereo or 48 s mono, with latched rolls and footswitch control.
    • LOUDER: a mastering limiter.
    • DJFilter: a DJ filter and kick kill.
    • Washout: a delay that melts into a cloud.
    • Takeoff: risers and downlifters.
    • Gooey: a mix bus compressor.
    • GRDELAY (was GridDly): one tempo-synced delay with six engines.

    Stereo: on the MS-70CDR, EuGate, Sweep, Breather, S.GN_L, Scrub, GRDELAY, Choral and GRDLOOP are stereo. WaveFold, DualShft, DirtBox and DubSiren hear both inputs added together and keep the dry in stereo.

    Every effect has a cover picture and a knob table in EFFECTS.md.

    Install: download Matujuice_ZoomMS_pack.zip (all seventeen) or single .ZDL files below and write them with Zoom Effect Manager. Steps in the README.

  2. v1.6v1.6: tempo from the custom firmware12 files

    v1.6: tempo from the custom firmware

    The tempo effects (DualShft, Choral, EuGate, DubSiren, Scrub, Breather, GridDly, Sweep) are now made for the custom MS-50G firmware zoom-ms-modding (MOD 0.4 or later). Tested on a Zoom MS-60B running MS-50G firmware.

    • No Tempo knob: they play at the pedal's tempo (MIDI clock, tap or patch tempo), and the pedal's tap button shows on them.
    • While a MIDI clock runs they stay on its grid. MIDI Start restarts them on the downbeat, and an effect switched on or loaded mid-song lands in the right place.
    • After Stop they keep running at the last tempo. On stock firmware they play at 120 BPM.
    • Rate and time knobs keep their free Hz/ms values and note values.
    • EuGate's Reset loses SYNC (OFF, NOTE, PEDAL).
    • Removed: SyncEQ, the iPhone (Mozaic) bar sync, FOLLW and the twin Tempo copies. For stock firmware and the Mozaic sync, use v1.5.

    Eleven effects: WaveFold, DualShft, Choral, EuGate, DubSiren, S.GN_L, Scrub, DIRTBOX, Breather, GridDly, Sweep. Knob reference in the pack README.

  3. v1.513 files

    Twelve free effects for Zoom MS pedals, made for synths and drum machines. All tested on a Zoom MS-60B (MS-50G firmware).

    New effects

    • DirtBox: multi-model distortion with a 3-band EQ.
    • Breather: tempo-synced pump with a built-in reverb.
    • SyncEQ: bar-synced EQ.
    • GridDly: tempo-synced delay with several engines on a Type knob.
    • Sweep: phaser, flanger and filter in one bar-synced effect.

    Changed

    • Choral is rewritten as a pitch-tracked choir that sings the note you play.
    • Bar sync on slots 4-6 now works through FOLLW (see docs/IPHONE-SYNC.md).

    Install: unzip Matujuice_ZoomMS_pack.zip (or take single .ZDL files), load them with Zoom Effect Manager. Patches that use Choral need their knobs set again.

  4. v1.41 file
    • Tempo is now on knob 8 for DualShft, Choral, EuGate and DubSiren, matching Scrub. Patches saved with older versions of those four need their knobs set again.
    • DubSiren: new Trig modes SHold and SPuls wait for the next beat, so the siren starts on the beat and stays in step with the bar.
    • EuGate: new Sync setting Reset SYNC (works like OFF) for bar sync. Shift now delays the pattern instead of advancing it.
    • DualShft: delay times can sync to the tempo (1/32 up to 1 bar).
    • iPhone bar sync v2: the Mozaic script no longer needs to know which effect is in each slot. See docs/IPHONE-SYNC.md or PatchStorage.
  5. v1.31 file
    • Bar-sync reset on the Tempo knob: DualShft, Choral, EuGate, DubSiren and Scrub now have a twin Tempo knob that holds each BPM twice. Stepping between the two copies of the same BPM restarts the effect on the bar.
    • iPhone bar sync: a Mozaic script in AUM flips the Tempo knob of the effects in slots 1 to 3 over USB SysEx on every downbeat, so they stay locked to your drum machine. Setup: docs/IPHONE-SYNC.md
  6. v1.21 file

    Scrub buffer 7.9 s, Pos reaches 6 s back.

  7. v1.11 file

    Two new effects and a better Mix.

    • S.GN_L: a broken digital line (packet loss, codec damage). File SGNL.ZDL.
    • Scrub: scrub through the last 6 s and freeze the grain where you stop.
    • Mix on every effect is now a DJ-style crossfade: dry full up to 50, wet full from 50, both full at 50.
    • New Choral cover. Tested on a Zoom MS-60B running MS-50G firmware.
