modular · berlin school territory

before techno had a name, before drum machines were affordable, there was a small group of West German musicians playing modular synthesizers in basement studios with extreme patience. klaus schulze, tangerine dream's edgar froese + chris franke + peter baumann, ash ra tempel's manuel göttsching. they took the english psychedelic-rock improvisation impulse and rebuilt it around the modular sequencer — a 16-step or 32-step machine that played the same pattern forever while the player adjusted filters, oscillators, and modulation depth in real time.

the result was hypnotic music. nothing CHANGES at the note level — the same 8-note pattern repeats for 20 minutes. what changes is the TIMBRE. the filter slowly opens. an LFO modulates the resonance. a second oscillator detunes against the first. nothing about the notes tells you what minute of the song you're in; only the timbre does. that's the genre.

the pattern here is a classic Berlin School motif in C minor: root, 5, root, b3, 5, root, 5, b3 — eight notes, repeats four times. on the pulse-pad program the modular's filter is doing the work, sweeping under the LFO. think of this as the START of a song you'd let run for 20 minutes, adjusting filter cutoff and resonance live.

delay + plate on by default. half of berlin school is the SPACE around each note. every modular session was tracked through tape delay + plate reverb; the dry signal was almost incidental. push: also enable tape for that slightly-wow'd cassette dub feel that the genre exited into during the late 70s.
