Analogue-sequencer

I had this mad idea last night (whilst watching the very excellent
portico quartet do their stuff in the union chapel in islington)....

you know how you can switch parts & have the mutes stay as they are,
or follow whatever is set up in the new part?

I'd like to be able to switch to a new part but have some of the
/tracks/ carry on playing what they are playing from the previous part.

in my hypothesis, one would achieve this by holding down the track
buttons for the tracks one wanted to keep going, whilst selecting the
new part.
reselecting the new part would introduce the new part's patterns for
these tracks. one could perhaps change the tracks from the "old"
pattern to the "new" pattern one at a time using this method.

there would need to be some way to indicate which patterns were active
from each part- maybe the part indicators could flash alternately..

obviously, the same effect can be achieved by simply copying or
ghosting patterns/bars amongst parts, but one needs to plan this in
advance & what I want to do is be a little more spontaneous than that.
 

I am really liking the v4 software now, & have it & the mem-x in both
machines. btw, the older machine (the RGB one with no sides on it) had
the main proc. board nearer the front of the case & so I had to do a
little metal-bending to get the mem-x to fit. no biggy, but a caveat
for other early-adopters, perhaps.

something I couldn't figure out- I have a track with several short
arpeggio bars one after the other. I can get the bars to repeat as
many or as few times as I want by using the reps count, but the last
bar just keeps looping around when what I want is for it to play up to
it's rep count & then go back to the first bar. I'm guessing this is a
global bar count thing, but I couldn't disable it.
what's the quickest way to get each track to loop around independently
of the others, i.e. based purely on it's own bar lengths, rep counts &
so forth? I'm quite happy to do the maths myself when I want two
tracks to last the same number of bars.... paul?

ah, one last thing- does anyone else feel that the midi-mixer controls
are in the wrong place now (v4)? I keep reaching for the knobs above
the track buttons.... wouldn't that make more sense?
