Adding Aftertouch and Portamento to a Korg Polysix

Excellent Polysix mod by Chip adds aftertouch and portamento:

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)


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
