Ambience

Composed and performed on my eurorack modular system, there are no post edits or processing after recording. Only two sine wave oscillators are in use here, in concert with a lot of CV and processing. The key motion is derived from a cycling envelope going through a sequential switch which is advanced by the EOC trigger from the envelope. That envelope is CV multiplied with two quasi-sync'd LFOs, and drives modulation of four drone parameters in sequence: wave fold amount, wave offset, sub-oscillator filter cutoff, drone pitch. The drone is frequency divided with a sequencer, for use as the sub-oscillator and as the clock source for the arpeggiated texture. The arp texture is heavily processed with clouds in spectral madness mode. The arpeggio sequence is generated with arpitecht clocked at the frequency of the suboscillator, which is fed into brainseed which is clocked and seeded with random ticks of the fast clock. Additionally, a turing machine is advanced with a subdivision of the envelope clocks, and which in turn changes the notes in the arpeggio and the envelope length.
