i'm sorry, phil, but this is far too complicated. the whole undertaking does not meet practical needs. for comparison purposes: let's take a quick look at this excerpt of the manual of korg's m1:
this simple function transfers play data to a pattern by coping from a track. the only thing you have to do beforehand is to set the time signature and the length of the pattern by using the pattern initialize function. compare that easy method to montage's complex and convoluted procedure! let's face it: user arps are frighteningly difficult to make, therefore, i put user arp creation somewhere in between rocket science and brain surgery. unfortunately, the montage is an overly and unnecessarily complicated board.
