Welcome to the OscPocketM (OPM) - the portable beatmaker for the M5Stack Core 2!
In your hands you will have 3 synthesizers and 1 drum machine that all can be sequenced and used to produce songs.
The synthesizers have selectable waveform, a low pass filter that can be modulated, an adjustable envelope and an optional second detunable oscillator.
The drum machine has seven sounds: kick, snare, open and closed hihat, clap, tom lo and tom hi. All sounds can be tweaked.
All sounds can be balanced using the built in mixer.
The synths have a piano roll step sequencer and the drum machine has dedicated 5 track step sequencer.
Sequences can be chained using the song editor.
There are also utility functions for saving and loading setups and sequences, as well as copying and clearing sequences and settings gate times.
All software is running on the Core2 including sound generation using the excellent Mozzi library.
OPM is free software and open source. Download, build, learn, modify, improve and share!

That's crazy!
Does it have some midi (or other protocols) connection possibilities?

Thanks!
It is based on the Core2, it is a fun ESP32-based small unit I got as a gift. No high level connections out of the box, but MIDI would be possible. But as it has micro SD-card reader, I plan to add a MIDI export function.
It also has a DAC out, but I didn't get that to work properly to wire up an audio out. All audio is recorded with the Zoom H1 put very close to the small built in speaker!
It was a fun project, but it got a little bigger than I had anticipated.

DAC output now works and is described in the updated manual. You can now easily connect the OPM to an audio input.oscillator wrote: ↑Sun Sep 19, 2021 7:45 am It also has a DAC out, but I didn't get that to work properly to wire up an audio out.
