Hello,
Here is a compact and very affordable DIY synth. It is build with a Teensy 3.2 microprocessor. I designed it especially for children workshops. Kids from 10 manage to assembly their own unit quite easily, under the supervision of an adult. I found I can teach a lot with it : electronics, coding, wood crafting, and of course music. Children can create and tweak their own presets with a standalone app made with max MSP. It is battery operated and has its own amp and loudspeaker.
Here are some features :
- 15 capacitive pads
- 4 voices polyphony
- 1 band-limited oscillator
- ADSR amplitude envelope, LP filter, filter envelope, LFO, reverb
- portamento effect
- 15 presets, 8 scales, transpose
- stand alone application for presets programming
- MIDI
- budget : around 30€
I won’t start an online tutorial neither give building instructions. Here are some reasons.
- Most of you asked for a ready-made synth, or almost-ready kit.
I don’t want to sell a product. I am not a business and don’t to start one. I am not interested in monetising either the MiniTouch.
- others ask for complete code and design schematics.
You don’t learn anything doing this way. I also don’t want my work to be spread out without any control.
- I receive a lot of requests everyday.
I am just an individual hobbyist. I realise won’t be able to provide support and advice. This project is just getting too big for me.
The tutorial is almost finished, but I won’t lunch it. I continue to do workshops in France where I live, but I won’t go online. I am sorry for those who are waiting. Who can find dozens of tutorials on the internet. I recommend Notes and Volts series.
Emmanuel
