MT doesn't swallow incoming NRPN

I'm working with my Alesis Ion, which knobs sends absolute NRPN control.

I have some algoritms to translate those to RELATIVE midi cc, that works well

when making a mdi thru in order to pass the key playing and some not translated nrpns, MT doesn't swallow the entire NRPN, only swallows the last part of it (cc 38 and its value. B0 26 xx)

example of midi message trigger:
B0 63 0E B0 62 01 B0 06 pp B0 26 qq

swallow incoming message checkbox checked and stop processing unchecked.

I've tried between "" and (). doesnt work

Thanks

Hi Rick,

You could try 'swallowing' each message in the string individually?

B0 63 0E

B0 62 01

etc...

Hope this helps..
