Ketron SD2, SD1000, Motif and GM sounds are in vArranger your SF2 sounds too
All other can be selected by INS files
Most of GM/GM2/XG/GS messages are supported, including filter cuttof, fine tuning, etc...
I think i7 can handle full arranger and vocal processor. vArranger actually does not handle microphone input, so you need another software to do that. so you need sound card with drivers that can play many software together.
I had the Integra 7 for some days, and was able to tune it for vArranger after few hours.
