I love to know how many sonar users think ACT needs to be redesigned . Does it work as intended all the time for you ?
How many times do you have to fiddle with the settings to make it work?

I could never figure out how the heck it works... admittedly I didn't try very hard. If I can't manually set the controller to a parameter in Sonar or use the right click MIDI learn feature (which may be part of ACT... IDK) then I just don't bother. I should probably learn how to use ACT properly though.

I use it with my Roland PCR to manage my synth and plugs,it's okay here.

Midi learn .. ? Last time midi learn worked for me was sonar 6 ..

When using your Roland PRC how many times did you have reset up act in preferences ? And dose it work every time you wanna map a knob? My akai mpk 49 frequently needs to be set up over and over..
I never can just grab a knob and learn it 1,2,3 . Always fiddling to get it to work .

MIDI learn is indeed very hit or miss. I'd say it works for about 50% of the parameters I've tried it with and sometimes it will respond to certain controls on my controllers but not others. Kind of strange actually and the way it works seems to be different in different areas of the program. One nice thing though is it seems to work quite well with FX Chains so if you set up the effects in the chain to respond to the chain's controls then map those controls to the controller the success rate goes way up.
 
Obviously that only works for things you can cram into an FX Chain though.
 
That actually gave me an idea. Wouldn't it be cool if we could send channel and other parameters to the FX Chains? It would make it a convenient place to control a whole range of related stuff in one place while taking advantage of the better MIDI communication set up. There is however Channel Tools which works great in the Chain Modules and it controls many of the things you'd do right on the console strips anyway so it's a nice alternative.

It has worked ok for me when I use it, which admittedly isn't all that often. I use it with my AlphaTrack and with my GR20 Guitar Synth so I can use the pedal on the GR20 to control pedals in TH2.

I combine ACT and Remote Control (MIDI learn) together because ACT alone doesn't allow my MIDI keyboard (A-800PRO) to control tracks/buses flexibly. I sent a feature request for ACT redesign (A-Pro control surface plugin redesign to be more precise) early this year but I'm not sure if CW cares about ACT anymore.

Funny this thread came out. I just pulled out my Axiom 61. I need to set it up in X2.

I think ACT could be a lot more user friendly.  I have found it very unintuitive and haven't had much luck getting it to work.
When I have tried to work it, I found it did weird things that weren't consistent and didn't seem to keep my settings.
I have since ignored it.

ACT is a good idea that could use a better implementation.
