If you try to sequence the Harmonic Weightings in the Shaper CPU usage goes extremly high, up to a level where the computer isn't usuable anymore.
Though, if I use a midi controler on the Harmonic Weightings to change the settings this does not happen.
Not sure if this is a bug or just in how the contraptoin works. But wanted to point this out.
Check out the Help pages on this contraption and you'll see that each time Shaper gets reconfigured, it runs through a fairly taxing arithmetic calculation. Probably, that's what's sucking so many CPU cycles. Though this may no explain the difference you see in using a MIDI controller.
Exactly, that's the whole thing. Why can I manipulate it live with controller, but not sequence it. Seems to me it should be similar in CPU usage.
