I asked Roland for these:
- remote control so there's no handling noise
- lower low pass filter freqs (40 and 80hz)
- optionally treat 1/8" as line input instead of mic input
- optionally treat headphone out as line output instead of headphone output
At least the guy said the requests were forwarded to R&D, though that'll probably take forever for a V2 given how slow Roland is at releasing gear updates :-P
So if nothing else, take a few moments and email Roland on their contact page if you're missing anything ;-)
