For those of us who are novices with synthesizers, could someone please explain what “dual processor effects” and “chorus effects” are. Thanks

The dual INSERTION EFFECTS are those that are applied to any VOICE that are apart of the Voice routing.

Call up any VOICE in VOICE mode:
Press [F6] EFFECT>
This is a shortcut to the EFFECT edit screen
Press [SF1] CONNECT
Here you can view the various EFFECT blocks. The ones labeled “INS A” and “INS B” are the dual Insertion Effect blocks. In the upper left corner you can see the potential 8 Elements (multi-samples) in this Voice. They can each be routed either to the “INS A” block or the “INS B” block or “THRU”. You will notice if you move the cursor around in this screen, that you can route A>B, B>A or A and B can be in parallel.

The dual Insertion Effects are very akin to the effects an individual musician would connect to directly. Like on a Guitar it could be a Distortion and Wah-Wah - we’d consider these the “personal” effects belonging to that individual musician. On a B3 it might be an Overdrive and a Rotary Speaker Effect - again these would be the personal effects of the organ player.

The SYSTEM EFFECT on the other hand (REV and CHO) are effects that recreate the outside environment. The REV (or Reverb), is reverberation and is the decay in the sound environment after the signal source has ceased to vibrate. It gives the sense of room acoustics. The CHO (or Chorus) block would be better titled “Time Delay” effects as these range from very short delays (Phasing, Flanging, Chorusing) on out to long delays (echoes, multiple repeats, etc.). Again, these are designed to recreate the environment in which the music takes place. These work exactly like a mixer with two auxiliary sends - every channel on the mixer has a send amount control to these two effects - they are shared by all PARTS on the mixer in a SEND/RETURN scenario

Personal Effects = INSERTION EFFECTS - signal routed inline
Environmental Effects = SYSTEM EFFECTS - signal routed via SEND/RETURN

You can see the routing scenario diagrams of the signal by looking in your REFERENCE MANUAL on the following pages:
VOICE mode = page 19
PERFORMANCE mode = page 20
MIXING mode = page 20

THanks, makes a little more sense now
