Here is first sound made using simple granular synthesizer I have written in Pure Data running on Raspberry Pi 3b+.
Arduino synth using Mozzi library adding some noise, Volca Bass for lower notes, arpeggio sound from NTS-1 (and reverb), Zoom MS-70CDR (reverb, delay), Arturia Keystep sequencer.
You can download original audio file from soundcloud & feel free to use it.
