as an instrument.
The voice begins with logic-driven oscillators. Frequency modulation, detune and PLL/ring-inspired treatments are being explored as a flexible sound-generation core.

DESIGN NOTES
Inside CMOS Voice.
01
Two oscillator paths
Oscillator paths are planned to support layered tones, detune and audio-rate experimentation.
02
Modulation and treatment
FM inputs, CD4046 PLL-based techniques and CMOS switching invite nontraditional timbres.
03
Analog conditioning
TL074 stages are planned for buffering, summing and level handling.
