I want to begin transitioning away from Gigastudio (into which I have invested heavy time and $$$ sadly) and into something else. Supposedly MachFive 2 will read Giga libraries, so it seems like a possible choice, though MachFive has some limitations (e.g. according to MOTU it won't translate Giga key layers, supports fewer simultaneous midi channels in stand-alone).

If I could install both Giga and MachFive on the same PC and use them both at the same time, that would be a very helpful way to bridge the transition. Anyone know if this is possible?

This is for a stand-alone (not plugin) use.
