personally I would prefer 2), simply because it allows you to build custom
widgets as Pd abstractions. a tracking area can be built quite easily with GOP.
Mouseup is a bit of a maverick: you want to be alerted regardless of
mouse position, i.e. any canvas or even outside Pd's territory.
Otherwise one could easily get the equivalent of a dangling midinote.
I wanted to provide an illustration of what is possible with just a
mouse-up event in vanilla Pd.
Here is a small animated gif screen screen capture of two abstractions:
https://raw.githubusercontent.com/chr15m/pd-push-and-hold/master/screencast-examples.gif
These use the pd-push-and-hold GUI plugin which sends global mouse-up
events. Other than that they are built using one vanilla hslider and a
canvas each. The plugin is available via externals search.
The first one is useful when you are building effects which have a
quantized range that you want to operate with a finger on a touch
screen. For example if you are playing live music and you want a
punch-in effect to turn on when you're pressing, and the ability to
quickly switch between four versions/settings of that effect (for
example four different delay line timings, or four different synth notes
to be played as you drag.
The second one is useful for selecting a start/end range. So you might
hook it up to a sample looper and you can use a finger on a touch-screen
to select small ranges to loop over in real time.
Anyway, I've scratched my own itch with this plugin for the Raspberry Pi
touchscreen thing I am building.
If the mouse-up event was made into a global that would do away with the
need for a plugin.
If there was a 2d surface which worked like hslider + vslider in a
single UI that would enable even more interesting widgets to be crafted
as abstractions.
Cheers,
Chris.
