Env:BP Time:Channel B Volume - where is this source?

I can't figure out where this source is in Absynth -

On the Cone Angle preset there is an X - 'Square Gate Rate' and Y 'Gate Depth' pad.

Under the Assignments tab these belong to parameters :

X is Env: BP Time: Channel B Vol
Y is Env: BP Amp: Channel B Vol

Pressing Add does not show these parameters on the list on the assignments tab. I looked at the Envelope page as BP could stand for breakpoint? but found you couldn't assign them.

Going off track - In the envelopes section Channel B vol is listed there, that's the only place I can actually see it.

 

If you go to Envelope panel and select just Channel B Vol envelope, you will see the Control tab is glowing. Now if you right-click the Perform tab and pop it out in a separate window, then tweak that square gate XY pad, you will see that the envelope indeed does change its range and timings, there's an overlay showing you what's happening. If you click on individual segments, you will see Time macro/Time scale/Amp macro/Amp scale parameters show up per segment. That's how you do it.

 

Thanks for explaining how to do it EvilDragon! I was using Absynth in Logic, so no pop out screens (forgot about that in stand alone) it would have taken me a long time to work that out. Thanks again.
