Man, this has proven to be harder than we thought it would be. We really don't know enough about synthesizer theory to create something really 'tuneful' yet. It's better than our earlier effort though. So far we've managed thirty minutes of this kind of stuff on the old synth (don't worry

, it's only three minutes of it)...
This has been digitized off the C60 chrome cassette that it was recorded directly on to. It seems to have a huge amount of bottom end mass in the 13Hz ~ 20Hz range. Probably because we chose a 128' and a 64' wavelength to start from. I'm surprised the cassette deck managed to record it down there. I could have chopped it out with a 20 Hz high pass filter I guess but it lost something when I did it.
This old synth is mono analog and has no midi and no pattern storage so you have to set up your initial patch manually. Then you can go and twiddle knobs and sliders once it's up and running. This patch has been set up with one of the two VCO/VCF/VCA combinations and the three envelope generators being driven off the eight step sequencer and the other VCO/VCF/VCA combination off the keyboard. That's why the repetitious pattern is coming out the right (sequencer) and the atmospheric (keyboard) stuff is coming out the left.
The old synth's sequencer is not like a modern midi one. It just allows you to create a new note from the key currently being played by turning one of it's eight knobs to the right to create a higher note or to the left to create a lower one. It sounds like it can manage about four octaves difference from fully left to fully right. Then you can choose how many steps you want it to cycle through - from 1 to 8. This one was 8 steps. Finally you can vary the speed of it. I think it's the kind of sequencer that created the synth line in The Who's Baba O'Riley.
This whole thirty minute piece was created by setting up the initial patch, setting off the sequencer then adjusting one knob at a time to try and 'play' the synth's various oscillators, filters, envelope generators and amplifiers in some sort of sympathy with the sequencer. The keyboard wasn't touched at all aside from the initial note.
There's spring reverb and tape echo running around from the board as well. It's been kind of fun keeping it up for thirty minutes not really knowing what is going to happen when a knob gets turned.
We're a bit bereft of ideas for side two at the moment. Our current efforts haven't produced much. We'll have another go tonight.
