|My synthesizer was now essentially made up of the Oscillator, a VCA and an Envelope. I had also built myself a Keyboard from the manual of a “Dr.Boehm” organ building kit. The key contacts were self soldered.
So far this was quite nice but I still wasn’t able to produce the typical “moog sounds” with it. At this point I still had no clue of how to get it working. Instead I enriched my synth with a sequencer. To that time the “field-effect transistors” had just come out and were available to people like me. I didn’t build the sequencer like one knows it from the moog with all the knobs, but completely electronic by using the field-effect transistors together with condensers for memorizing the pitch value.On one of our following gigs, where I had used the sequencer, there was a well known scene musician from Hamburg, Okko Becker. After the gig he came up to me and told me that he had a minimoog which he would love to connect with my sequencer.
I told him that I could arrange this but that I would need to take his minimoog with me for a few days, to be able to ajust my sequencer to it.
No sooner said than done.. for the first time in my life I got my hands on a real moog. In that instant the scales fell from my eyes and it was clear that the only element I was missing was the filter.
I tried different circuits from a good electronics handbook, which should make the filter controllable, but the typical moog sound still didn’t come out. So I borrowed Okko’s moog once again and opened it up to look at how the VCF was built.
I had a weird feeling for a long time, because I knew that the VCF was patent-registered. But one could only build a VCF one way.
The few units which were built by PPG were in low count compared to the quantities of moog. (At the moment I am only talking about the analogue synths, later in the Wave, we built in chips which were licensed on their part)
2. “Der Sequenzer”
Mein Synthesizer bestand nun im Wesentlichen aus dem Oscillator, einem VCA und einer Envelope. Ein Keyboard hatte ich mir auch zusammengebastelt – aus einem Orgelmanual von einer “Dr. Böhm”-Bausatzorgel sowie selbst zusammengelöteten Tastenkontakten.
