  1. v1.2Erik37 1.2Latest4 files

    Install from https://genkigenki.github.io/smk37/ (Chrome or Edge), or with any Felucca installer: one package per model.

    • Release noise level: TONE & TOUCH K4, 0 (off) to 100. 100 is 1.1's level; 40 at first.
    • Notes that held on (erik37#1): only the pedal holds notes by default.
      • The PEDAL jack's rest position is learnt once the reading is steady, or set on PEDALS & PADS K3 (auto, open, closed).
      • The mod wheel does nothing unless PEDALS & PADS K2 makes it sustain.
      • SEQ REC is a sustain on/off toggle, its light on while on (SUSTAIN ON in the header).
    • Pad light: PEDALS & PADS K4, 45 / 60 / 80 / 100 %; empty preset pads are now pale instead of dark.
    • USB: pitch bend is sent only on real changes (no stream from a wheel held off centre); a note the keys hold is not struck again when the computer echoes it back; the auto-save waits until the reverb has died away.
    • Sound: a cleaner output stage (the full 24-bit word, no DC after the room and resonance, a finer tone EQ).

    Packages: erik37.fwsc SMK-37 Pro (and Starrykey 37 Play), erik37-elite.fwsc SMK-37 Elite, erik37-mke.fwsc MKE-P37, erik37-fm1.fwsc FM-1 (untested on a unit). Identity _480102.

  2. v1.2-usbtest1Erik37 USB test (macOS)Beta2 files

    Test build only, for checking the USB audio device on macOS. Not a release.

    On macOS 15 and older, Erik37's USB audio device may not appear (MIDI does). This build lists the audio interfaces first, as Vox37 does since its fix for the same problem.

    • For the SMK-37 Pro only (identity SMK-37 Pro_480102).
    • Install it with the page's "install a file" option or M-UPGRADE, as any package.
    • Please report: does "ERIK37" appear in Audio MIDI Setup on your Mac (and on Windows / Linux, does it still work)? Does playing fast still lag or crackle?
