Not sure if you would call this a bug or maybe it’s intentional because it’s to cpu heavy for the machine or something.
Anyway if you have waveform view open and try to copy the pad to an empty slot by holding the copy button and press the to & from pad there’s a pop up saying “no sound assigned”.
And if you’re in loop/slice multi mode and have waveform view open and try the copy command nothing happens.
Would love if you didn’t have to close waveform view before you try to copy a pad.
