hey m0d !
congrats for the video idea 
First of all
I need 60 tracks to fill
my own screen like
your left screen
devoted to the
pattern matrix
let’s say that you want to work with 100 tracks
that control all the woodwinds, brass, percussions,
keyboards and strings of a
Modern Symphonic Orchestra.
you should logically want to create 5 groups of tracks
maybe more if you need to separate more precisely
violins and violas ans violoncellos for example
with the actual GUI, you can anyway
correctly see 60 tracks in the pattern matrix
if you’ve got enough screen resolution.
so even if you only collapse tracks
in the pattern editor,
the problem will remain the same
in the pattern matrix, still limited
to 60 tracks in a screen…
for now I suppose that you try to circumvent your problems
with the usage of top track colors. (? no?)
for example :
every woodwind = PURE RED
every brass=PURE BLUE
every percussions=PURE WHITE
every keyboards = PURE PINK
every string = PURE GREEN.
.
.
You double-click on a color on the pattern matrix,
your pattern block and view are automatically
deplaced to that position.
but I understand that
with those 3 big screens, and large array of tracks,
the colors on the top of the tracks are not
efficient and helpfull enough to help you to
organise your song setup
I think that grouping and collapsing tracks
BOTH in pattern editor AND in the MATRIX view
will be necessary in your situation
However, we must keep in mind that
Renoise tends to avoid “floating windows”
or “hidden informations”, because we believe
that the power of the interface is that
it allows you to quickly access to all the informations
you need during the complex composition
and mixing process ; so the more you hide,
the less you see what you hide and it could
maybe become slower to handle the
complexity of a try-and-error composition
process.
I also propose that we could be able to “extend”
top track colors so that they become
background track colors.
BTW, top track colors are not available by default in the mixer view.
Why ?
thanx for reading
Whoa. Exactly how many tracks is there in that song of yours?
Let’s move on, and for those that don’t know already - rhowaldt went out of his way to amend things so please don’t be mean to him
