Jeff Hunt DIY Synth Project - The Portal

Published on Oct 2, 2016 Jeff Hunt

"My DIY groovebox. I am a beginner. Just got started this year after watching videos by Casper Electronics. Highly recommended! I followed up by researching 9v/12v single supply circuits, and after much trial and error I came up with this final product. Many thanks to the folks on the Synth DIY forums on Facebook and elsewhere for tons of advice. Also many thanks to Nicolas Collins and his book Handmade Electronic Music for lots of tips. Feel free to ask any questions, and thanks for watching!

Square/Sawtooth/Triangle waves
16-step sequencer based on a simple 40106/4040/4067 design for the oscillator
8-step sequencer based on a 40106/4040/4051 design for drums

I did install a clock input but haven't even tried it yet. I think I may have to build an external clock adapter module to make it work right due to the way I timed everything.

Sound processing circuits based on the following designs with my modifications:

--MS20 style lowpass filter with lfo modulation by Tim Escobedo

--"Little Angel" chorus by Frequency Central

--"Funky MF" multimode envelope follower filter by Frequency Central

--"Echo Bender" delay by Casper Electronics

Rhythm Section comprised of variations of Andromeda Space Rockers by Eric Archer"
