EDIT: this is actually working as I originally expected: the MIDI channel is all that is needed to target specific tracks in the Syntakt. The problem was that I misunderstood how a Max object routed CC messages to different channels. Leaving this in place in case it helps anyone looking to route the same CC to multiple tracks. Thanks to @sezare56 for the help.
I have an intermediate MIDI cc question for the Syntakt (though it may be general enough that other devices behave the same way). A simplified version of what I am trying to do map a single slider from from Max/MSP and have it change the same parameter on multiple Syntakt tracks at the same time via MIDI CC messages.
As an example, the slider value should change the tracks’ Amp attack value on tracks 1 and 2 at the same time. From the manual in Appendix B, the Amp Attack Time is mapped to CC 79.
What I have tried so far was to set up something so that CC messages for CC 79 are sent to the Syntakt on both MIDI channels 1 and 2 (default MIDI channels for each track). However, only channel 1’s Amp attack is changed. Even if I disconnect the routing for channel 1, when I send the values to CC 79 on MIDI channel 2, it still changes track 1.
The manual also notes that Amp Attack Time is associated with NRPN MSB 1 and LSB 24. Do I also need to send some kind of NRPN message so that it knows what track the CC 79 messages should be targeting?
Thanks for looking at this and let me know if anything is unclear.
