OK, I'm a little slow, but let me see if I understand:
I can set the Timefactor to send midi clock data (if I'm up to date), but setting this means i can no longer pass any other data through the time factor, such as the program change or CC messages for the device I'm trying to send the clock data to? Is what I'm trying to do really so wierd? So maybe I need to find something to put further upstream in the midi signal that will send the midi clock data to be streamed through the devices and leave the factors set to thru? is there another device that sends clock messages wia tap tempo that i can buy besides the ploytec 34one? Is there anythig else that i can do? Arghh!
