Hello Samuel,
i did run some tests:
Reaper 4.78, Win7, x64:
Automation works when i draw an automation item. In my test i did route to 'osc1 morph'
Orion x32:
Automation works
Reason 10:
This host added vst support only some months ago. The implementation still can be buggy.
I am unable to reproduce your problem. I also did not receive similar reports from other users.
1) It would be helpful for me if you record a step-by-step video with your mobile phone and send it to me. I sent you a PM with my number.
2) I must know if you refer to the 32bit version or 64 bit version of Icarus
3) Do other Tone2 plugins work?
Best Regards,
Markus
