I just happened to be looking for updated info on getting Catanya to work in Sonar. I'm running Sonar X1 Producer Expanded 64-bit and I have Catanya visible as a soft synth through jBridge. This edition of Sonar does now appear to recognize this 32-bit VST plugin. I used jBridge, however, just to see if it made a difference. I still can't get Catanya to do anything in Sonar.
As another forum member in this thread said, Sonar apparently can't see it as a soft synth even if if it's configured that way, which it should be, so it doesn't show up as a MIDI input.
I don't think this has anything to do with 7Aliens, it's a Cakewalk issue. Catanya works swell in other DAWS such as Reaper, which is the option I tend to use to employ it. Reaper also has many more MIDI and audio I/O features than Sonar.
If you insert through the track inspector FX option as a soft synth, it will disrupt the MIDI track and you won't hear a thing until you click the blue button to turn it off as a soft synth FX.
I've e-mailed 7Aliens to ask about a 64-bit version of Catanya.
