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)
