Hi Donny,
My previous reply to your question did'nt show up, even though the reply counter showed "1", very strange, oh well I will try again.
The only DSP Blocks that can be applied to the multipads are "Reverb 1" and "chorus 2" both of which also provide the reverb/chorus on a global basis to all the sections.
You can change the type of Reverb/chorus by entering the mixer and selecting "eff type" page, then select the relevent DSP block on the left side "Reverb 1/ Chorus 2" and then selecting the effect type on the right.
To adjust the level of the chosen effect select "eff depth" page (in the mixer) and adjust the "Reverb 1/Chorus 2 levels" on the PADS section.
Hope this makes sense.
Paul.
