Ensoniq VFX device. Copied from the ESQ1. My VFX version seems to be 2.10 (02
0A in the inquiry result ID message). Unfortunately, my documentation is not
up to date so if this driver does not work with yours, check the sysex size
first and then the message types. I can't deal with several version of VFX
because I have only one. This could be made with first getting the version
and then choosing the good parameters in a table with the version as the key.
