True. But DX11 ACED2, V50 ACED3, YS200 EFEDS, and DS55 DELAY are not yet 
supported.

VCED parameters: same for all models, with a few exceptions (e.g. DX21 
stereo chorus)
ACED parameters: not available on DX100/27/21
ACED2 parameters: not available on DX100/27/21, TX81z
ACED3 parameters: V50 only, DSP FX parameters 
EFEDS parameters: YS200/YS100/B200/TQ5 only, DSP FX parameters
DELAY paramaters: a simple digital delay with only 2 parameters (ON/OFF, 
LONG/SHORT) available only on the DS55.

I think we could have several different drivers, but they could share the 
same patch/bank/library format and a lot of common source code. Maybe it 
is possible to disable those parameters that are not supported by a 
selected synth type, but still keep the edit parameters visible, maybe 
grey colored ?

I am afraid not. The DX100/DX21/27 are not multitimbral. I don't know how 
much the DX11 and TX81Z are similar. The V50 and is probably more 
complex. This model even has a bank memory for 100 performances.

I have to take a look in my old YSEDITOR source code and the SysEx specs. 
But if I remember correctly I had to write different code for the TX81Z 
performances and for for example the YS200 performances. The performances 
look very similar (8 parts, each with things like volume, pan, patch 
number, note-limit H/L, etc.) but the sysex code is not compatible. But as 
I said, I have to look into that to be sure.
