Serge Modular

"This is a mid-vintage serge panel, probably dates back to the early eighties. Serge panels are still being produced by a company called STS systems. The panel modules and functionality can be found there. This particular panel can be used as a complete 2 osc synthesiser in itself (minus a dedicated lfo) or can be used to expand a current modular synth. It might make a good starter panel because includes a psu purchased from STS systems that will power 2 panels. I also have 8 or so patch cords i can include. The unit is also rack mountable. This synth is a bit difficult to describe in comparison to hardwired commercial synths, the closest thing I can compare it to soundwise might be an arp 2600, the oscillators sound bright and musical, and are very stable. the filters are very 'natural' sounding really unlike any other synth I've heard. You can get an enoumous range of timbres by cross modulating the oscillators together, sync sounds, ring mod type sounds. the wavemultipliers are used to take a simple waveform and shift its harmonics around in different ways. They are good for metallic tones and strange textures and each one has a slightly different flavor. There are many ways to overdrive or feedback audio signals at different points in the synth which can be useful as well. The slope generators can be used in too many ways to list; simple envelopes or as weird lfos for example. One of the unique features of serge synths in general is the versitility of the modules for the amout of space they use. This synth is really for someone who wants to explore textural sounds,it can be wired to do 'classic' analog sounds extremely well but you would only be using 5% of what it can do. It is controlled via standard 1v/octave cv/gate."
