The 921B type slave oscillators possess four outputs that can be used simultaneously: sawtooth, sinusoid, triangle, square.

There is also an output generating a trigger signal synchronous with the square signal and with an identical width, which lets us trigger envelopes and sequencer in a cyclic manner. This output is visible only visible at trigger input menu level.

Sawtooth

Square

Triangle

Sinusoid

These oscillators are independently tuned with the “frequency” knob. This button possesses a coarse +/- an octave per semi-tone setting with a left click and a fine tune setting +/- a semi- tone with a right click.

The “range” selector allows the setting of oscillator range on 6 positions: Low, 32, 16, 8, 4 and

2.With the Low position the oscillator can be used at a very low frequency (on a cycle of more than 6 minutes). The other positions set the oscillator to octaves 1,2,3,4 and 5. That is to say the note C3 is played respectively on C1, C2, C3, C4 and C5.

At the Low position the oscillators perform modulations using lower calculation power than the other positions.

Two modulation inputs allow the separate setting of each of the oscillators in the group. They are very useful for modifying the tuning between oscillators thanks to a low frequency oscillator, a keyboard follow or other modulation source.

Like the controller modulation inputs, they can be connected to the output of another module. Connected to an oscillator functioning in the same audible spectrum, they can obtain sonorities with FM characteristics.

A synchronization input and the associated interrupter allow the synchronization of the slave oscillator on one of the other oscillators. In this case, the synchronizing oscillator will be heard while the synchronized oscillator will improve the tone.

In the low position, the synchronization is said to be “hard”, which is to say that the synchronized oscillator will restart a cycle for every cycle on the synchronizing oscillator.

In the high position, the synchronization is said to be “soft”, and in this case, the synchronized oscillator will only restart its cycle if it is coming to the end of the cycle when the synchronizing oscillator begins its cycle.
