Hi again folks: The current way that I do probing for synths is reliable sometimes and with some synths. I have been trying to decide how I could make it more reliable more often. The reason we have these probing problems is because many of the synths are not designed to interact with the system controlling them. They are designed to take data and commands and just execute them. What I have been toying with doing is just cycle through the ports checking to see if I have CTS and if so, saying okay, I got it. My question to you all is do you think this is an acceptable way of going about it? It would mean that a person with a serial synth would need to have it on the lowest serial port to have it found reliably. I would be interested in your opinions. If you don't like the idea, then I would like a workable suggestion for how to make it work. I am not interested in criticism without an alternative solution. Kirk
