Hi @ll,
I just bought a TSynth at Tindie. It’s a really cool thing! It simulates an analog synth on the Teensy-3.6. 6 voices are possible. 2 oscillators, LFO, filter with ADSR and various small specialties make a lot of fun creating sounds.
Additionally to the kit you need the Teensy-3.6, audio-shield, pots, encoder, OLED display, buttons, LEDs. Altogether (with shipping to Germany) I spent nearly 100€. It took a day (about 6 hours) to build it. Now I have to make some additional parts for the case and several knobs for the pots (3D print).
Here a re some pics:
Perhaps later I can send some audio examples. But Simon from Electrotechnique has made some good ones already. And he is working on a T_4.1 version…
