Change kit using MIDI

I know i can do this on the mono machine with

F0 0 20 3C 03 0 58 n F7

where n is the kit number

but I can’t seem to crack the Rytm. From some other posts like Program change messages not handled as expected I thought it should be

F0 0 20 3C 07 0 52 n F0

F0 0 20 3C 07 0 52 n F7 but that doesn’t seem to work
