Re: [Gimp-user] MIDI controllers for controlling brush size and colors [was: Save Export Complaints]

Ah yes, MIDI pedal. Just another feature here. You can control the
brush size with a foot pedal. I do music so have gear like that. Foot
pedals are probably over kill for average users though. The Korg
Nanokontrol is the ideal unit for most users but yeah, that largest
brush size thing needs changing.

Just another insane thing. MIDI can be sequenced so you can run a
sequencer and have say red pulsing into blue or brush size swelling up
and down. I'd suggest that's going to far though. It gets a bit
glitchy with some features if it's changing as you do a stroke. This
is the cool thing with open source software though. Some mad features
get added. Photoshop will never get MIDI, that's for sure.

Yes, exactly, that is the problem. You can change the default brush
largest size before compiling. Presently it's too large and this needs
discussed with developers. I found somewhere how to change that code
and it's very easy to do. Just find that one value and change it but
also some UI that can be added to alter that largest brush size from
Gimps UI. My Gimp is currently installed in the standard way. Next
time I use it for painting I will compile and I'll document how to do
that. At present, I can't even remember how to do that. I'm not even
writing this from Linux. Somewhere on my Linux machine is a note on
how to do it. This needs changing on Gimp. Whether you are using MIDI
or a tablet slider, the largest size of brush is ludicrous. It effects
all the brush sizing - stepping it up etc. It's no good.

One problem with Gimp 2.8 is that the
top size of the brush is far too big. If you compile from scratch you
can change that. This needs to be mentioned in the Gimp developer
list. It's also possible to have UI to set that largest size of brush
so it's not too big. I've seen the code that needs added to do that.
This all needs to be better sorted out to make Gimp more ideal for
painting.These are simple changes that need to be in Gimp. Changing it
and compiling is too much trouble.

Oh well...we used to have logarithmic brush size control. Now, you have a
linear space ranging from 0 to 1000.00 - if you have to control the brush
using a 2 cm course MIDI pedal, it simply won' t do -out of the box -
But I think it could be controled using the dynamics curves:
create a new brush dynamics, map the input control to brush size there, and
its curve so that the maximum size (right) is at roughly 10% of the graphic
