I have the exact same problem:
Automating the bypass parameter for tse 808 and tse r47 (standalone) doesn't work in SONAR.
All other automation is working fine:
I can automate all the other parameters, can create my automation lanes and the plugin reads it and reacts accordingly.
Only the bypass parameter shows this strange behaviour:
1. When I record my fader moves into an automation lane it doesn't record it correctly.
Normally it should create a continuous line at the bottom or at the top for the two different states, bypass on/off. Instead when I click the bypass button it just clickly jumps from bottom to top or vise versa and then imidiately switches back. So my recorded automation lane doesn't show two different lanes but only one lane with quick spikes whenever I tried to change the bypass parameter.
2. But even if I draw automation lanes by hand and do it correctly it doesn't read it. At that point in the timeline when the automation lane changes, the bypass button on the plugins interface reacts as if it had been pressed but the plugin doesn't really change the sound.
The behaviour goes in both directions. It doesn't matter if I start with bypass on or off. I can use both when I activate it by hand but with automation I cannot change it to the other state.
