MIDI-to-Parallel decoder with 32 TTL-compatible outputs

• 32 parallel TTL-compatible outputs
• mdec32-s firmware for controlling up to 32 general loads (solenoids, relays, lamps etc.) via external drivers:
  • user selectable MIDI channel 1-16
  • user selectable starting note
• mdec32-sam firmware for controlling up to 16 Stop Action Magnet (SAM) switches via external drivers:
  • user selectable MIDI channel 1-16
  • user selectable output pulse length (range 100mS - 1.6S, step 100mS)
  • fixed starting note (per request)
• mdec32-pwm firmware for controlling up to 32 solenoid-driven percussive instruments via external drivers by single pulses or PWM signals depending on note velocity parameter:
  • user selectable MIDI channel (1 out of 2)
  • user selectable starting note (1 out of 8)
  • user selectable velocity responce curve (1 out of 2)
  • Pulse mode with selectable velocity-over-pulse-width mapping (1 out of 4)
  • PWM mode with selectable velocity-over-duty-cycle mapping (1 out of 4)
• opto-insulated MIDI input
• MIDI Thru output
• recognizes MIDI Note On/NoteOff messages
• recognizes MIDI All Notes Off message
• supports Running Status and Zero-velocity
• recognizes and ignores System Exclusive and Realtimemessages as well
• user options (on request):
  • non-continuous note range
  • responding to other MIDI messages instead of Note On/Note Off messages​
