On Saturday, August 13, 2022 we will be working on the Adafruit Customer Support Forums. If you visit over the weekend and things are not complete yet, please check back later, https://adafruit.com/forumupdates
Just in case your synth rig needs a sub oscillator, here’s a DIY project from Analog Labs Swiss:
This is an easy DIY Sub Oscillator project I’ve made for my Behringer Crave synth but it’ll work for Euroracks also. It tracks a Sawtooth or Triangle signal (10Vpp with 0 offset) or a simple Square wave and output a -1 and a -2 octaves down Square waves. Avoid PWM signals. It’ll not good at traking them. It was tested at 9V and 12V and works well with Crave & Neutron Synths from Behringer but also with Eurorack’s VCO. CD4013 is powered from 0 and 9V (or 12V). The 100k linear potentiometer acts as a mixer to blend the 2 sub osc signal output. At 50% position, it’ll output the famous SH-101 Pulse sub oscillator.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
