User Manual

The only suitable Expression Pedal for your PRODYSSEY is

the model "Yamaha

FC7" (or 100% compatible). Other mo-

dels MUST NOT be connected as these may cause permanent

damage to your PRODYSSEY!

The PRODYSSEY ASB automatically recognizes a connected foot

slider once the unit it switched on; however, it is activated only after

it has been fully pressed and released.

With Key Follow selected, the cutoff frequency follows the played

note according to the selected intensity. Setting the fader to maxi-

mum sets the frequency control to 100%, thus tuning the filter out-

put, so it can be played via the keyboard.

Selecting the Sample/Hold function enables noise or one of the

oscillators to function as a modulation source for the filter cutoff.

This makes it possible to use Filter FM in the audible range, which

can create particularly interesting sounds.

The Sample/Hold function produces a stair-step or random modu-

lation signal that can be used to create fascinating sound effects by

tweaking the cutoff and resonance. For example, you can try ran-

domly jumping the cutoff frequency or playing a pattern. Play around

with the parameters of the Sample/Hold mixer and the Sample/

Hold itself.

You can use the LFO’s sine wave to modulate the filter periodically.

Change the LFO’s frequency to change the modulation rate.

You can use the AR or the ADSR envelope to modulate the filter

cutoff frequency. The cutoff frequency follows the envelope’s shape

according to the selected intensity.

HPF Cutoff Frequency

The cutoff frequency of the high-pass filter is the frequency below

which the spectrum is attenuated, and the sound’s fundamental

tone is de-emphasized. You can change the cutoff frequency ma-

nually. The high-pass filter has no resonance and cannot be modu-

lated. Use it to create unusual sounds, like for example to re-create

the sound of analog hi-hats or other sounds that should be free of

bass components.
