Are you sure about that Joe?
I thought I knew what I was talking about but I researched it and here's what I came up with.
Select any R1 Voice and enter
VOICE SET.
TAB to the
Effect / EQ page
Scroll down to the 2nd listing: DSP... there are 2 parameters for this. Top line is to select the
DSP Type, the bottom line will display the
Variation for that particular DSP Type. There doesn't appear to be a way to edit the variation... it is set by Yamaha.
Example: If the DSP is Reverb, the variation will be the
Reverb Time. If the DSP is Delay, then the variation will be
Delay Time or some other variation such as
L/R, C, or R/L.... etc.
Thanks for bringing up the question. Even after years of playing the keyboard, I'm still learning something new.
