10 years and a few days ago, I was running a DIY Synth workshop with STM32F7 dev boards in our kitchen in North London... Still have ~10 of these boards.

Here are also two videos (live performances) of some softsynths (some with MIDI via USB support) which we built in these workshops (I did quite a few of those in that year)...

Another track/demo made with Forth and https://thi.ng/synstack (see previous toot), at least partially, i.e. everything but the drums... Improvised live via MIDI (Korg Nanocontrol), then sampled and arranged in Ableton...

Just discovering #looptober and wanted to share this old Forth experiment (from already 9-10 years ago 😱) with my https://thi.ng/synstack VM and its DSP/Synth vocab, all running on STM32 dev boards. This Forth-based stack VM and also its earlier non-Forth, DSP graph-based version in the same repo are all portable C11 code, independent from any audio drivers/libs.

The first example an extended version of the second. The entire Forth source for the 2nd example is shown in the attached image. It includes the note/scale selection/definition, code to create a synth with 2x oscillators and 2x LFOs, ADSR, foldback distortion and the probabilistic sequencer.

Playlist of 40 other demos (more varied & interesting than the above two examples. Will share & talk about some more of them in due course... ;)
