It looks like the third from the last number is the value. If so the attached should help. In this example I’m sending the value pp to CC 60 on MIDI CH 1. Change the output to any CC you would like. The second to last pair of digits looks like it is just a checksum so we capture the pattern in local variable oo but ignore it. It is only there to complete the pattern.

Just an educated guess due to the pattern of numbers. I suspect the number oo is just a checksum. Different vendors calculate the checksum in different ways. Steve Caldwell Bome Customer Care * * * _Also available for paid consulting services: bome@sniz.biz_ ---

My guess is this is a Roland device (by the second digit). You can find their checksum calculations in most of their manuals or maybe even search on this forum. ---
