I've always done it with a Switcher. This method will allow any number of 'splits': Each output of a Switcher is fed into a separate Monitor. One feed from each Monitor is fed back to the Switcher via a transformer that converts the Note On message to a message that raises the switch position. Another feed from each monitor is sent to your instrument(s). Note Offs become a problem, so I split them to bypass the switch and send them to all outputs. (There is a way of getting a transformer to do this without first converting the data to CCs. I forget exactly what it is right now.) You have to have 'feedback' on the Switcher turned on. Input | Transformer - Splits Note Offs and sends to all Monitors - | Switcher | | (multiple outs) | Monitor | | Out Transformer - feeds back next position message to Switcher - The feedback transformer from the last Monitor in the series resets the switch position to 0. If you set up an array of, say, ten outputs you can always use less, say six, by altering the feedback transformer on output 5 to reset the switch position to 0. You can cycle all sorts of things this way. Cheers, Stephen.
