What BEETLE-BLUE does

  • Six drum lanes play two built-in kits: BEETLE's 14-sound PCM ROM kit and MONOLITH's 16 procedural drum patches.
  • Build 48 patterns of up to 16 steps and chain 64 positions in Song Mode.
  • Press SEQ for the tracker, then K1 moves steps, K2 picks a field, K3 sets values and K4 sets BPM.
  • Give any step up to three effects: FILTER, DRIVE, DELAY, REVERB, CHORUS, VIB, ARP, CUT, TREMOLO, VOLUME, PITCH and REV.
  • Hold FX and press keyboard keys for momentary Punch-In FX, with a global dry/wet BLEND and pitch shifting.
  • Load your own samples into slots U01 to U13 and shape START, END, ADSR, GAIN, DRIVE and CHOKE.
  • Mix the six lanes with GLO, tune each component, and store twelve global User Kits shared across projects.
  • Save to 12 project slots, back up as .bdrum files, and record stereo or six mono stems over USB-C.

StatusNot scanned yet

We couldn't tell which file in this release is the FM-1 one, so we didn't scan it.

Les scans every firmware here whose file is public, and shows what it checked and what it found. A scan lowers the risk; it can't rule it out. This firmware is made by its author, not by Les or M-VAVE. Back up first, and install at your own risk. How Les scans firmware
