"The synth is triggered by a piezo disc which is sensitive to how hard you tap the top panel giving subtle differences in the envelope. The sounds are generated by a VCO optionally modulated by a frequency sweep, LFO, Pitch CV or all three. There is a simple envelope generator with a fixed fast attack for punchy percussive envelopes and variable decay for super short to really long decays (5 seconds+).


The sounds produced by the synth are not limited to what you would expect to associate with drum sounds and can vary from big bass drums to tapping on glass to UFO space drum-wobbly things! Not only does this Drum Synth do sonic justice to the original but we have also put our own spin on it with extra modifications including:
* Attack on/off
* VCO & LFO wave shape selection
* Pitch CV input"

"The Teenage Engineering is a endless pandoras box of workflow and fun. This video jumps into the void which we call the Teenage Engineering OP-1."

In honour of #DoctorWhoDay w/ a Raspberry Pi Zero


Published on Nov 23, 2017 Pi Synth

"As always, synthesized live on a Raspberry Pi Zero, featuring 10 simultaneous synths, 3 different synthesis models, audio and graphics captured real-time running on a £4 computer.

It's nice that the software still works - mine has a dreadful tendency to code rot if I look away for a few months. The visualisation is somewhat different since the last time I posted this - the texture that drives the colours is now computed rather than loaded, and as a result it's easier to tweak the visuals, so it all looks cooler and more electro-neon than it did before. The software now runs client/server. Synthesis is within a separate server application, the client is in charge of pushing MIDI into the server, and - unusually - pulling audio back. So the server knows nothing whatsoever about platform MIDI or audio capabilities. Visualisation is also done client-side. So the server does nothing except pull in commands and push out short blocks of synthesized audio."
