I have been experimenting with "stacking" DSP effects and registrations. ("Stacking" DSP effects involves going to the Effect page of the Mixer and tapping Assign Part Setting.)
In particular, I am trying to modify the preset OverdriveWahWah voice to be touch wah instead of auto wah.
OverdriveWahWah comes with the Multi FX Crunch Wah insertion effect, which does auto wah. I moved this effect to the Insertion Effect1 slot for convenience, and then turned off its auto wah component by setting WAH SW to Off.
Then I added VCM Touch Wah to to the Insertion Effect2 slot, and set it up to sound the way I wanted it to.
I set this modified voice to be Right2. Both effects slots had their Assign Part set to Right2.
I saved this setup in a registration file. But I found that when I loaded the registration later on, I got inconsistent results. It seems like perhaps a registration file does not reliably store this "stacked" effects setting.
Can anyone verify that this is a known property of registration files? Am I doing something wrong? Is there a better way to store this modified voice and its stacked effects setting?
