[Bluemusic-users] Brainstorming Automation Curves (Issue #120)

[Steven Yi <ste...@gm...>]

Hi All,

For Issue #120 [1], the request is for providing different curves for
automation.  Issue #321 [2] is somewhat related but has to do with
BlueSynthBuilder UI elements being exponential.

>From what I understand, there's a relationship between these things
that I'm trying to sort out and would like some input.  What I'm
thinking is:

1. The *value* of a widget should be considered linear across a range.
2. A UI for Widget may provide options to be linear, exponential, or
logarithmic. This would affect how the widget shows and sets the
value.
3. An automation could be presented using linear, logarithmic, or
exponential scales.  These can be different from the widget's
settings. If we add curves to the picture, this would mean that a
linear automation between two points will be visibly rendered in
different ways depending on the type of curve as well as the type of
scale.
4. Because a user might changes scales, each automation curve should
have the values to describe its curve as well as what scale it uses.
5. The user may ultimately decide to further transform the value
within their Csound code.  There's not much I see at this time that
Blue should do for this situation.

I think this makes sense to me and the next step is to create a test
project that renders each type of curve with each scale and has a knob
on the side to see how that all works.

BTW: I would like to get started on 2.7.0 changes soon, so I have
reassigned some 2.6.1 tickets to other milestones. I think
BlueSynthBuilder is well overdue for a full UI overhaul. I will likely
change the Knob look and feel once again.  Also, by redoing the entire
BSB interface using JavaFX, this should prevent the current issue
where if an interface has many knobs, they all slowly render.  I also
started doing experiments with modifying the manual to use LaTeX
instead of Docbook, though I am still experimenting with this, with
plans to make a decision for 2.7.0.

Thanks!
