I strongly feel if you are going through ACT to control a softsynth, Sonar should STOP MIDI CC to the softsynth as well.
Normally that is the case. When CC is used by ACT plug-in, it is no longer sent to the Synth.
But there is one exception: if you have more then one ACT Plug-ins with this MIDI input, only CCs assigned in the last one are blocked.
Possible solutions:
a) use only one ACT plug-in per MIDI device
b) reprogram your controller to use undefined CCs, not used in softsynths (but they still will be recorded into MIDI track if you modify parameters with track armed)
c) add AZ Controller as yet another ACT plug-in (as the LAST) and in its Options tab set "Block all channel messages". That is not going to work in case you really want some controls or keys from the same device delivered to Synth.
For ACT Dynamic Mapping (Learn) I strongly recommend to install and use "AZ ACT Fix" utility. Alternatively, you can use "ACT Editor" from MarKo or manually edit XML files. If you ignore that advise, sooner or later you will be confused even more.
