Degenerator2 Polyhonic DIY Synthesizer & Sampler

[SteveBar]

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.

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?

Ich fände es sehr cool, wenn es jede Menge ordentliche Funktionen für ne Drumsektion gäbe! Ratcheting, Verstotterbiegung, die ganzen Schmankerl halt. Mir fehlt irgendwie immer ne gute Drumabteilung.

Gute Idee, aber der Degenerator soll in erster Linie ein Synthesizer & Sampler werden.

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.

Kleines Update am File System.. Die Patch-Parameter stehen jetzt in einer JSON Datei und können beliebig erweitert werden. Dazu nutze ich die JSON Library in Arduino.
Die meiste Arbeit steckt mal wieder in den Details und der grafischen Benutzeroberfläche (GUI)
