Im trying to use Max to hack the controls on my padKontrol... So i send some sysex to the padKontrol to envoke native mode...cool

When the PK is in native mode it sends out SYSEX from allknobs, buttons, pads, encoders... So i have max set up to recieve the SYSEX from the buttons and pads, and then convert it to a MIDI Note message...cool...

When i turn a knob on the pk it sends out the sysex to max, i use match, then unpack, and route the bytes nessesary to convert byte 7 to MIDI CC#, and byte 8 is just sent to a ctlout to preserve the changing CC value. 

Problem is Max locks up on me all of the time when i start turning the knob, it will work for about 30 seconds or so then Max will lock up- and i have to do a hard reboot of windows. Can someone take a look at my simple patch and maybe tell me what im doing wrong, or let me know if there is another way to convert sysex to a cc. I have the latest version of Max, Ableton Live 6.07 ( latest version ) and win xp pro sp3. I also see that it has locked up on me even if i dont have Live open. I am also 99% sure that no MIDI is feeding back from Max or Live. Thanks!!

sysex-to-midi-cc-question

Two things about your patch. First, whenever a sysex message would be sent with a length other then 9, the synchronization is lost. It might be better to use the designated 240 / 247 as separators. The other thing is that the patch chords going from unpack to ctlout cross, meaning that the order is reversed. Still this might not be contributing to the fact that max crashes on you. Did you try playing with the overdrive settings?

Thanks!!! Turning Overdrive on seemed to do the trick. I guess i can further play with the overdrive settings in the DSP status menu. Just wondering what the overdrive actually does?

AFAIK, Overdrive means that the event-level scheduler operates at the CPU interrupt level.

I don't see why this should lock up, I am 100% sure its your 1% 

As jvkr already pointed out, the zl group will get you unsynced, just 

imagine its playing a note in-between which will have 3 bytes...

simply skip the zl group, match is designed for listening to a stream, 

and the reversed order could be corrected by two ctlouts.

Defining the Midi outport by a letter is pretty old style, have a look 

at midiinfo, that way a changing Midi setup won't be that difficult to 

(If you paste the patch double click the loadbangs, to fire them...)
