yes I have some conversion programs for DW6000 and DW8000 and Yamaha TQ5 (might work on other 4 op FM synths). It was an attempt to make the BCR as if were part of the synth.
You will find videos and the programs on Royce Craven
I believe there are others that have done this 'machine in the middle' conversion program with a micro-controller of some sort.
All the best
Royce
