K.B. Modular synthesizer

Here you can see the two main boxes plus most of the smaller one and a portion of the rack mounted ones to the right. Above the speaker you can see some of the unmounted modules.

These are the two K.B. keyboards, the lower one has a dual vca with 2 inputs/ channel at the far end, looking at the bottom one you can also see pots for the "keyed sequencer". The close ends of the keyboards show envelope generators and volt/ octave outputs.

This is a horrid picture of the setup on a card table I think it kind of gives a descent idea of the size of the system.

Here again at a later stage you can see some of it. The top box of knobs shows what the internal/ external patching looked like, the second box down was somewhat internally patched although I chopped most of the wiring as it was not functional and most of the labeling for the switching was a number from 1 to 5 making patching interesting in that one could just record numbers instead of patch configurations in a notebook. Some of the modules had neat voltage controlled panning functions, None of the vco's were tuned, it was never right with the keyboard scaling either, I could never keep more than an octave in tune at once and that was only with one of the vco's, adding another just didn't work. The phasers were well beyond the average 90 deg shift , they were probably at least 180 or some undetermined amount, all filters could be brought to oscillate through the resonance control setting, they may have been built around the "Curtis modules" as I seem to remember sealed black multi pin cubes in most of them. Everything drifted like crazy, the power supplies were under regulated or loaded too much by the time all of the modules were hooked up. I never had any literature on this beast making repairs and adjustment quite difficult and time consuming. I owned this for almost ten years, I sold it a few months ago and miss it dearly.
