#verbos electronics

Just realised that I hadn’t written about this project of mine here, so thought I better make a post sharing this video and a few thoughts.

I sort of put this project on the backburner for a bit and not a lot has changed with the patch since this video was made back in July, but it’s prompted me to go back over it and think about a few ways of improving the patch, though I fell it’s pretty close to where my inital idea was to take it, without further building and implementing this as a part of a larger instrument/synth.

As said in the video, it’s more or less an oscillator patch heavily inspired by the Verbos Electronics Harmonic Oscillator Eurorack and Buchla format modules with a few unique ideas. So it really takes an additive approach at it’s core with a bank of eight sine waves, the first being the fundamental with the rest tuned to proceed through the harmonic series. The amplitude levels of each harmonic can be adjusted independantly allowing for a range of different organ like timbres.

Where it gets interesting though is that each harmonic gets it’s own wavefolder, where higher order harmonics and distortions can be generated through folding the simple sines back in on themselves. There is an oscilloscope implemented for each harmonic so that the wavefolding can be visualised. There are two outputs running from the sine bank which can be balanced with a crossfader. One of these is simply the summed output of all the harmonics, but the other is the output from what’s called the harmonic scanner. This allows crossfading between the eight harmonics and when modulated with the incorporated LFO, makes for nice shifting harmonic and melodic effects. The master output also has it’s own oscilloscope where the signal is plotted on both x and y axis.

Again I’d also like to thank both Randy Jones and Roman Thilenius for their help and design contributions with some of the more tricky aspects.
