Nope... not possible... but you can do it via stacked mode... press both split and stack buttons at the same time, choose to copy layer A to B, hit write... now you have two identical layers, and you can set each layer completely independant of each other... thus you have two AMP envelopes.... in addition to all the other stuff... Stacked mode is more useful than you'd probably think
Now why didn’t I think of that! great tip, it’s got my brain churning now thinking of what else I could be doing with this. Thanks
... a lot actually... one trick i use quite often is to use layer B as an "FX layer"... I copy layer A to B, then I choose a delay on layer B, and set the FX Mix to 100%... after that i control the mix amount with layer B's volume parameter... both layers are then playing the same sound, but you only hear the repeats from Layer B...
Why not use a delay on layer A instead? ... well... because you can make all different kinds of crazy delays this way... if you transpose layer B an octave up or down you'll have pitch transposed delays... if you change the attack and release parameters on the AMP envelope, you can get softer repeats... if you change the cutoff to darker, you'll have darker repeats, even with the stereo delay... you can even copy in totally different layer programs and have delays that play along in a delayed fashion to the main layer A sound...
You can also copy layer A to B, and then hard pan each to the left and right for very wide stereo perspectives without any beating like with a standard chorus...
There are loads of options when using layer B...
... only drawback is the halved polyphony, but 8 voices should be enough for most tasks anyway...
