DIY drum machine sequencer with samples

From wikiluntti

Introduction

Teensy / Arduino/ ESP32 based drum machine/ sequencer with high quality samples. Use MIDI to transfer data from sequencer to synth. / Groovebox.

The knobs:

  • Bpm
  • Play/ record
  • Free rhythm / on beat
  • Track number selection
  • Length: 8 / 16 beats
  • number showing current step
  • Drums; shown below.
  • Display? showing the situation

Arduino can play some audio samples at the same time, but the memory and clipping might be problems. ESP32 is more powerful. Teensy is very expensive.
