Verifies oscillator output frequencies and signals using scope probes.

Tests LFO output waveforms (sine, sawtooth, noise) and frequency response.

Inspects VCA envelope generator output waveforms and control responses.

Tests a simpler envelope generator for repeat and single-shot modes.

Monitors filter control voltage variations with keyboard and filter controls.

Checks filter output DC level stability and potential bias issues.

Performs audio checks for all oscillators, noise, and pitch controls.
