Use the rotary knob to select different timbres (1-127 and Random). The selected timbre is shown in the
display box. There is also a blue modulation input for controlling timbre changes from an external source.

This is a gray slave output for controlling slave oscillators. Patch this output to a Mst input of a slave
module. If you control a slave LFO with this signal, the rate of the LFO will be five octaves below the
pitch of the master oscillator.

KBT is the hardwired connection between the oscillator and the keyboard (and the MIDI input). If KBT
is activated the oscillator will track the keyboard at the rate of one semitone for each key. If KBT is not
activated, the keyboard will not affect the oscillator frequency.

A slave oscillator can be controlled by any of the master oscillators for multi oscillator setups. Any pitch
modulation or keyboard tracking that affects a master oscillator pitch will also affect a connected slave
oscillator pitch. If you do not connect a master oscillator to a slave, it will produce a waveform with a
fixed pitch, starting at E4 (329.6 Hz). You can control the fixed pitch with the Detune and Fine controls.
• A slave oscillator is not affected by the Master Tune function unless it is connected to a master oscilla-
tor.

This slave oscillator can produce one of four waveforms. You can select Sine wave, Triangle wave, Saw-
tooth or a Square/Pulse wave. It has an FMA, an AM and a Sync modulation input.

This red input is used for synchronizing the oscillator to a control source, which could be another oscil-
lator, an LFO or the keyboard. Synchronization forces the oscillator to restart its waveform cycle, in sync
with the waveform cycle of the controlling device. The oscillator will restart whenever a signal present at
the sync input increases from 0 units to anything above 0 units.
The pitch of the controlling oscillator will interact with the controlled oscillator pitch. For a traditional
synthesizer sync-sound, start with the two oscillators to the same pitch and connect only the sync-con-
trolled oscillator to an output. Turning the tuning knob or modulating the pitch of the sync-controlled
oscillator will produce radical changes in the timbre. See
