Variation; Sync; Bpm - E-Mu ProteusX Operation Manual

Variation

Sets the amount of random variation on an LFO each time a key is pressed, which is
useful for ensemble effects, where each note played has a slightly different modulation
rate. The higher the number, the greater the note to note variation in the LFO rate.

Sync

Key Sync or Free Running. With key sync selected, the LFO wave starts at the beginning
of its cycle at each key depression. With Key Sync off, the LFO wave begins at a random
point in its cycle on each key depression.

BPM

The BPM button allows the LFO rate to be controlled by the Master Tempo (located in
the Multisetup window). The Master Tempo can also be derived from an external MIDI
clock to synchronize the envelope times with external sequencer or arpeggiator tempo
changes. The chart below lists all the displayed musical note divisions when the LFO is
set to BPM. The "Master Tempo Clock Pulses" column shows the exact number of clocks
used by each note division based on the MIDI standard of 24 pulses per quarter note.
The LFO cycle will last for the exact note division shown.
