that's really sad... and of course annoying for us customers who spent a lot of time preparing complex sets. However, that's how business goes... Thanks Mike for the great work and support in the last few years :_(.
Years ago, I tested Forte as a basis for the Live setup to be used with my master keyboards and with multiple VSTis and VSTs, .
I found it not versatile enough. So I dumped it ans started to use Reaper as an Audio toolbox. I was able to do a rather complex and perfectly working setup, but I had to do quite a lot of programming with the built-in tools Reaper provides.
So I invite all Forte refugees to come over and join the Reaper forums. I and others will be happy to help with getting started.
