This was a fun thing: designing and building your own synth with low-cost parts. The Teensy 3.6 comes with PD and DSP functions. Listen to the example: all done with teensy in 1 take, no processing. Recorded with Xite-1.

I dig the Teensy 3.6, was gearing to make it an effect box for a didgeridoo.
Easy getting it up & running?

Yes, plug & play. But if you need more than the supplied delay time, you need to solder a memory chip on the audio board. I'm using the 6s delay one.
You also need to solder a SMD resistor over an capacitor, because the DAC is else quite noisy. And another tip: use separfate power suplly and USB connction, the USB port is otherwise noisy.
The library is quite powerful, but I added some changes to make it even better. If you like, I can give you my sources.

Sure, I'll try your additions!
Your first synth is pretty good, really!

wow, this is pretty impressive! running on such a tiny thing. How do you program the thing? And how do you get audio out?

I&m using the Teensy Audio board for audio out. The programming is working with Arduino IDE (Teensyuido). For the audio flow, there is a GUI (inluded or online), which creates the necessary data to be included into the main program. Search
https://www.sparkfun.com/news/2222#comm ... 81388b4567 and see a nice example. I also commented on this page and you can find my exttension there.
BTW: If you buy the Teensy, the Audio board and the 1MB memory chip together, Mouser sends them free to Japan.
