SQ-80 — Musician's Manual
9. OSC —Oscillator (Waveform) Restart
When ON: All three Oscillators are halted before the start of a sound, and are restarted together
when a key is struck, so that they will start out playing in phase with each other. Any phasing,
or "beating" between the oscillators (due to detuning, etc.) will be the same each time a key is
struck.
When OFF:
The Oscillators are not stopped before a new note is played, but continue to play.
Therefore the relative phase of the Oscillators will be unpredictable. This will tend to randomly
vary the phase shift and tonal characteristics of the sound.
10. CYC —Envelope Full Cycle Mode
When ON: The Envelopes will pass through their full cycles every time a key is struck. In this
Mode the SQ-80 pays no attention to whether you hold the key down or let it go immediately —
each Envelope simply 'runs' through all its stages (ignoring the sustain stage after
TIME 3) with
each keystrike. This can be useful for many percussion-type sounds, bell sounds, filter sweeps
and other sounds where you want consistently repeatable Envelopes that are not dependent on
keyboard technique.
When OFF:
This is the Normal Mode of operation. All Envelopes will go into the Release stage
when the key goes up, whether LEVEL 3 has been reached or not.
