16-step sequencer and granular synth
More info: https://groovesizer.com/red/
It’s based on the original Groovesizer mk1 Arduino project. It features 16 LEDs (one per step), 5 potentiometers, and 5 buttons, MIDI input and ouput on 5-pin DINs, MIDI sync in and out, and audio out (mono) on an 1/8″ jack. There are 32 user locations for saving patterns and patches. Up to 4 patterns can be chained together to create a 4 bar pattern. Note entry can be quantized to one of 12 pre-defined scales. Patterns can be triggered and transposed via MIDI. Notes can also be entered via an attached MIDI keyboard.
Features at a glance:
SYNTH
- granular synth based on Auduino
- synth settings saved with pattern
- Live Play mode (via MIDI keyboard)
- automatable grain decay 1 (sounds similar to filter cutoff)
SEQUENCER
- note entry for individual steps or groups of up to 4 steps at once
- rests, ties, slides and accents for each step
- pattern length from 1 – 16 steps
- pattern retrigger
- tap tempo
- 6 play modes (forward, reverse, pendulum, random interval, drunk, random)
- pattern transpose (semitones or octaves)
- adjustable note duration
- swing/shuffle
- MIDI in/out (note, clock sync, trigger)
- MIDI note entry
- MIDI transpose pattern
- send automation via MIDI cc
- note entry quantized to 12 preset or 4 user defined scales
- 32 save locations arranged in 8 banks of 4 patterns
- 4 play modes per bank (loop 1, loop 2, loop 4, random)
