Hello all,
I'm trying to look inside long sysex messages, change them and resend
My code is not working as I expect.
After 7F messages there goes some garbage zero and then it proceeds from 80. How can I do this ?
Subroutine showmessage prefix
Ass LA = 0
Ass LB = 0
If LB < ML +L
Mat LB = LB + $128
If LB > ML
Ass LB = ML
End
If LA < LB +L
if prefix != 0
Snd LA 00 00 MLA +F # for debug
else
Snd MLA +F # for re-send
end
Mat LA = LA + 1
End
End
End

Hi slmnv , To prevent infinite loops and 'play nice' as a processor, StreamByter has a maximum loop iteration limit of 128. If you need to get around this, then you can double-nest the loop giving you 128x128 max iterations as follows: assign LB = 0
while LB < ML
while LB < ML
math LB = LB + 1
end
endRegards, Nic. |

Hi Nic, apologies for not being clear with my question. I tried to do what you suggest with code shown above. But I see some unexpected output as shown in the attached image. Can you please explain what is wrong with the code I put above ? when I spot sysex message I start this subroutine and show all the bytes in the sysex before changing them and sending them back. Something like if M0 == F0 showmessage 1 end I expect to see ..... 7E 00 00 00 7F 00 00 00 80 00 00 00 81 00 00 40 ......... but instead I see what is shown in the screenshot. Attachments:

Hi slmnv , Hmm, that looks really strange. Have you tried adding 'log' statements after each of those send rules to see if either the 'else clause is being triggered or the event is being generated from something else. Regards. Nic. |
