Controller
Separate pitch, gate, and modulation outputs with a 0–5 V control range.
Instrument design.
The design targets six waveforms, independent pitch and gate control, frequency modulation, and a 12 dB/octave filter.
Signal and control.
Oscillator
Sawtooth, square, pulse, reverse saw, triangle, and sine outputs. Coarse and fine tuning, FM input, and pulse-width control.
Filter and amplifier
The signal passes from VCO to VCF to VCA. Low-pass, band-pass, and high-pass filtering combine with ADSR envelope shaping.
The hardware.
Front panel
Module controls and patch points on the assembled panel.
Breadboard prototype
Module testing before final assembly.
Thesis results.
The thesis presentation reports tuning across the 0–5 V control range, filter operation, amplitude control, and envelope shaping.
