I have tried Vstack and Forte2 on my PC to host PLAY Orchestra and both of these programs are not compatible with PLAY. In the case of Vstack, it only plays one side and in the case of Forte2, it crashes.
Any other programs out there that I can try?
I think that this question should be directed at EW, because if you don't use a supported host, they will always deny responsibility for the fact that something doesn't work...!
PLAY works with Bidule for me, even though it's not officially supported.
