In the screenshot you have two structures to select a midi channel (roland sysex) , a midi channel is made out of a tuple of two values e.g. midi channel 1 =(25,0) , channel 2 = ( 25,32) etc..These are then separated to feed into a template (not shown in screenshot )
In the past I used a data switch and depending on the input selector , it outputs/triggers the tuple ( blue structure )
The streamlined version ( red ) is a 'get element from an array that houses all tuples
[(25,0),(25,32),(25,64),(25,96),(26,0),(26,32),(26,64),(26,96),(27,0),(27,32),(27,64),(27,96),(28,0),(28,32),(28,64),(28,96)].
It's a life saver
