i did a google and came across some interesting stuff about the board, but no yay or nay on my question. i don't own the board so i have little time for experimentation, and as far as i've seen so far on the ipad control program, you can't adjust effects parameters. my example would be, trying to adjust the pre delay on a reverb. other examples would be selecting different verbs, or adjusting echoes time/feedback. the only workaround i can think of would be somehow acessing some efx presets on the fly, but still if there was a better way it'd be cool. as i'm slowly getting the basics down, i'm starting to miss my old efx knobs, when mix problems have been solved and it's time to have some fun. i think alot of these types of questions are gonna come up and be addressed as tablet mixing evolves, and the end users and manufacturers are gonna benefit from it! thanks again.
