Also, VDMSound does not slow down the SysEx's, though it buffers them (one by one) before sending them. I forget what the serial buffer is on the MT-32's microcontroller, but if dealing with small SysEx's then VDMSound's sysex buffering will help; if however the sysex's are larger than the ucontroller's buffer then it's not so easy.

Would it be worth introducing a parameter in VDMSound "max. MIDI bandwidth" or so to regulate this?

Just being curious what has happened with this idea.
