FAQ (possibly)
--------------
* Some programs can generate distortion : This is because the voice summing still needs some tuning. You can simply lower the volume on those programs.
* Some sysex seems to be corrupted : Even if the sysex checksum doesn't match, Dexed will try to load it (this is a kind of randomize feature). Right now Dexed supports only original DX7 sysex, other DX family sysex (like the DX21) is considered as random data.
* Dexed doesn't receive/send parameter data from/to my DX7 : Most DX7 parameter change are done via sysex and very few VST host actually implements sysex. I'm planning to do a standalone executable to handle this issue.
