I am looking at purchasing a MIDI foot controller board which also includes 2 expression/volume pedals. When using the control board with a midi link, can both pedals be used simultaneously with the nova system (ie. one to control the volume on a preset and one to control a particular effect within the same preset), or, do you need to assign them to either volume or expression but not both?
Unfortunately, it is not possible to use both pedals. The Nova System software only allows the use of one pedal (even through MIDI) and you'll have to choose between Volume (global) or expression (at preset level).
This feature is possible in G-Major 2. (it can actually support up to 4 pedals).
