Well, kinda in C Minor. In retrospect, it sounds just the least bit sharp. Duration is about 27 minutes. File size: 16.2 MB.
The diagram hints at just how flexible (and a bit overwhelming) an analog synth can be … and I don’t even have sequencers yet. Major, minor, augmented, diminished scales or triads; sweeping the VCF with different waveforms at different depths; changing the scale pitch with the modulation wheel; adding low-frequency noise for “interest” — just a few of the parameters that can be varied with this one patch. It pays to write down the various knob and switch settings when you get a sound you really like. Recreating it can be a bear.
