I was wondering about the expression pedal : According to the answer I got from an email to Korg, I should use the EXP2. Will this pedal be of any use outside of the G5 ? As in, can I use it as a volume pedal ? My guess is not, since it's a keyboard pedal. And I can't find anything on the net that suggests otherwise. But I thought I'd ask. And are there options other than the EXP2 (or the other 2 discontinued pedals mentionned in the G5 manual) ? Thanks.
