I started working on individual synth detection a long time ago but because of other bugs at the time I put it aside and rewrote the drivers to just pretend they have the right synth when they find something that talks on the serial port they are probing. Some synths you can look for specific commands and responces to determine you have the correct synth but on others I have never found ways of deciding specific synth characteristics. If someone wanted to take on writing probing and detection code that would be really cool. Currently, it isn't even on my list of things to do.
