Degenerator2 Polyhonic DIY Synthesizer & Sampler

Hello Steve..😀
Take a look here. I've described the query for the 360° pots in detail in the Teensy forum. https://forum.pjrc.com/index.php?threads/new-polyhonic-teensy-diy-sampler.76219/page-3#post-359161

Here is the current circuit diagram of the Pot panel in Degenerator2. The outputs Pot_COM0 and Pot_COM1 go to two Teensy Analog inputs

Thanks for sharing and your quick response! What a great resource!!!!
I was looking at the Alpha website yesterday and there is a new 3 phase endless pot called the RV113FF. Requires another ADC read per pot but has a very nice symmetrical output characteristic with respect to angle, which would greatly reduce the code and maybe even "free" smoothing.
RV113FF -> https://www.taiwanalpha.com/downloads?target=products&id=80

Also I noticed your clever idea about heating the pot to reduce physical resistance. What is the torque rating of the pots you ordered? Alpha's data sheet says: Rotational Torque = 10-200 gf.cm. Can you specify the Rot Torque when ordering?

I ordered the 360° pots from Mouser. Mouser doesn't offer a rotational torque option 🤔 At Soundwell, you can also order 360 pods. The farmers can also order them on request. However, the quantity is limited to 1,000.

So.. kleine Sommerpause 🌞🏖️🌻😎🌇
In dieser Zeit werde ich mein PC System erneuern. Das altes Mainboard mit einem i5 8600K und 16GB DDR4 Ram hat ausgedient und wird durch neues Mainboard mit einem Intel i5 14600K, 32GB DDR5 Ram und eine Samsung M.2 9100 SSD 1T ersetzt. Wegen der höheren Leistungsaufnahme habe ich dem System noch ein neues 850Watt Netzteil spendiert. Das sollte wieder für ein paar Jahre reichen. Mein altes System "entsorge" ich für ein paar Dollar bei einem guten Freund.

Der nächste Schritt in der Degenerator2 Entwicklung ist die Oszillator Sektion. Die Oszillatoren werden die VA Synthes, Wavetable und Sample Synthese besitzen ähnlich wie in der Jeannie.
Ich wünsche euch sonnige Grüße aus Wuppertal :)
