The problem with adding extra midi channel capacity to a modular synth is now you need more envelopes and amps to shape all that sound. EGs (envelope generators) and VCAs (voltage controlled amplifiers) have been ordered but in the meantime am using other means to trigger the extra channels. (I had enough oscillators.) Here an LFO makes a basic phone signal sound, which runs throughout this extremely modest piece. Drum samples were added in the second half.
