I tried converting the entire SOV set using Chicken Systems Translator and I found the translated library to be un-useable. For some reason the samples don't trigger at the right velocity and I can barely get any level out of them.
In my Roland 760 they are much much louder. As for the mod wheel, in my Roland the swtching does work well.I don't think the translated files worked in Giga. Perhaps there is some extra programming that has to be done after converting with this library (not impressive). I'm curious if you experience the same thing. Maybe your Akai disks will translate properly.
