This last week has been an exciting time for my pursuit of adding aftertouch to my Korg Polysix. As you know by now, I *really* want aftertouch vibrato on my Polysix…so a while back, I ordered a bunch of parts and dived in. I’ve been posting about my progress. In my last post, I described the electronics elements that I used to implement the arbitrary pitch bending that would allow for my aftertouch-driven vibrato. As a bonus, having arbitrary pitch control also enabled me to add portamento to my Polysix, which is another effect that I absolutely love. So, without further ado, now that I’ve put her back together, here’s my first demo of what she can do…
MCP4725 Breakout Board – 12-Bit DAC w/I2C Interface – Your microcontroller probably has an ADC (analog -> digital converter) but does it have a DAC (digital -> analog converter)??? Now it can! This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it the value you want it to output, and the VOUT pin will have it. Great for audio / analog projects, such as when you can’t use PWM but need a sine wave or adjustable bias point. (read more)

Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
