Midi2CV-Connecting worlds!

I was not sure this would be a very interesting build as it is not a sound generator per se, but it still will gonna save me the 150E it costs to get a nice commercial Midi 2 CV interface. This looked like the best DIY project I’ve found, it comes complete with the arduino code and all: It…

BH-101 Synthetiser

This is my first “real” voltage-controlled synth build using the CEM3340 clone the AS3340: The CEM3340 was the oscillator used in the famous Roland SH-101 and MKS-80. It has 3 waveforms: Ramp, Triangle, and variable-width Pulse. In my build I added a white noise generator, the Noise1B from ED: I’m mixing the 4 outputs with a GrandMixer DIY,…

BB BP-1 Filter

Next on the list is building great filters, both resonating High and Low Pass, voltage control is a must if I want this to integrate further on a CV controlled system. I found this great component manufactured by Alfa and distributed by Electric Druid: the AS3320, a clone of the CEM3320 as featured in the Sequential Pro-One and the Oberheim…

I just put together all the units I’ve been building. I just sticked the SSS sequencer, the PT39 delay, the 3080 Phaser, the Grand-Mixer, the 808 Kick Clone and the Nano-B synths onto a piece of plywood. Here is how it sounds through my iPhones mic and Youtube audio encoding.

808 Hi-Hats Clone on stripboard

After the successful cloning of the 808 Kick, I needed at least a hi-hat to go along. I found this great thread on electro-music, about building the 808 hats on a stripboard: Check the thread out here : So I decided to step up my game a little bit, and turned the soldering iron on.. After a first attempt,…

Grand Mixer DIY

Now I need to put all thiese “modules” together, so I’m going to build the simpler mixer I can think of… That design is exactly what I think I need:

808 Kick Clone

Nothing better than the 808 kick as a first beatbox build, a solid foundation… There are many designs around based on the original service manual published by Roland, including all the schematics. I got help from this one, as the original schematics have been redone at a larger scale: Just be aware that you are going to need…

SSS-Super Simple Sequencer

The Hackadays series by Elliot Williams are a gold mine: Logic Noise: Sequencing in Silicon This is a super simple 8 steps sequencer based on the Baby 10  featuring two 4017 ICs. Here is my breadboard rendition of it gating the power of a 4069/40106 based oscillator:

CA3080 4 Stages Phaser

I just love Electro-Harmonix phasers such as the Small Stone or the Electric Mistress.. I found these schematics to build a Small Stone replica using the CA3080 Operational Transconductance Amplifiers: The build on a breadboard looks like this: And the sound is great, here’s a demo using a great song by Adrian Nation, Five Fingers Rapid:
