This has probably been covered before, as it is something I'm sure many GPO newbies have been curious about, but I'm not sure how to do a search for topics related to it, and it probably doesn't hurt for it to be discussed again.
I know the mod wheel is considered an important aspect of using GPO. However, what about if one has a pre-existing MIDI or sequencer file, and wants to change the pre-existing string parts to GPO instruments?
Since those parts were not recorded using the mod wheel, one might not hear any sound. What does one have to do to hear the parts in GPO?
Also, since thereby one might have lost some of the expressivity possible in GPO, is there any way to get that back, without re-recording each part using the mod wheel?
(I can't say I'm used to that mod wheel recording yet either. I guess it takes some getting used to. One could only play the keyboard with one hard, if using the other hand to manipulate the mod wheel while playing.)
