Hi!
Can somebody explain me what happens with element 3 of Cool Cat Organ PRE1 087 (F07)
I'd like to understand why that high short sound doesn't repeat if I play legato; or better it repeats only if I play legato very fast, but if I play two notes legato with a gap of one second I don't ear element 3 on the second sound.
I'd like to control this thing in this sound making it play every time I press a key, even if legato and slow.
Furthermore I'd like to use this feature on other sounds.
I hope I was clear.
Thank you.

Ok,
I've found the answer myself.
It's in the common LFO which has a user wave that affetcs on the amplitude of element 3 bringing it down very quickly

Am I right?

Yes, you are.

The USER LFO in the MOXF engine can be set to be used as a modulation source in either a "loop" (repeating) or "one shot" fashion. This allows it to be used to create a one time event (which means it can be used to setup to behave like an envelope generator) - and not just the typical repeating modulation function so commonly associated with an LFO.

The percussion on a Tone Wheel organ has this type of behavior - this programming trick was used to mimic the behavior of percussion in the real thing using the sample-playback-based engine... "hit it and quit it" to get percussion, play legato for no percussion.

The COMMON LFO can be programmed to create a repeating or one time control function directed at any one, all or any combination of Elements. The Destination parameters include the available parameters within the INSERTION EFFECT, the VOCODER, or within the VOICE: Pitch Modulation, Filter Modulation, Amplitude modulation, Pan position, Resonance or LFO Speed (of the selected Element LFO)

This programmable matrix within the COMMON LFO allows you to address specific destinations. You can control the speed of an individual Element's own LFO with the Common LFO. (There is one Common LFO and each of the eight Elements has its own Element LFO). This LFO Control Matrix (called the "Box";) can be useful when programming behaviors within sounds like pads, that evolve over time, etc. Instead of the modulation being a static repeating speed you can adjust the speed (up or down) as time goes forward. Or use it to fade out or fade in Elements, etc.

In the organ Voices (tone wheel-type) that feature percussion, this USER LFO programming "trick" is used to recreate the important note-on behavior of the real thing. The USER LFO which has sixteen steps can be used to create a short, one-shot envelope, that happens only at 'first key-on' event. Here a very short 1-step USER LFO was setup to control (modulate) Amplitude. After the "1-step", the Amplitude is turned down so you cannot hear additional contributions from this Element until a new "1st On" event occurs.
