Hello Rui,
In the Activate - MIDI Controller window it would be great if a 'Momentary' tick box could be added. This is especially useful for turning plugins or plugin parameters on or off with a MIDI footswitch which mostly are toggle switches (pressing once sends a 127 and releasing it a 0 or the other way around depending on the polarity). Guitarix has this option too, this way I can use my Boss MIDI footswitch as an effect switcher. Thanks in advance!

afaics. most midi foot(switch) controllers can be (re)programmed to operate in the so called "latch" mode, which means that pressing once sends a 127(=on) and pressing it twice later will send 0(=off); at least roland's fc-300 works that way as from factory default.
i may add support to the "momentary" mode of operation, where depressing/releasing the foot-switch does send an immediate 0(=off) control change, also meaning that a value of 127(=on) is to toggle the target parameter state (127<->0), and 0(=off) is about to be simply ignored. or not, if one possibly admits either up or down edge-triggering... whatever.
meanwhile, you should check whether you can reset the foot controller operation to "latch" mode, the only that probably makes practical sense in qtractor atm.
hth.
cheers
Latch, that was the word I was looking for, not momentary :) I guess I need to purchase a Boss FS-5L for my FC-50 because now I only have FS-5U's which are non-latch footswitches. Or use Mididings with the FS-5U but that does make it a bit more complex. Guess I'm going to see if I can find a latching MIDI footswitch. Thanks again Rui!
done. svn trunk [r4106] aka. qtractor v0.6.3.13+
MIDI Controllers now has a new "Latch" mode property, enabled for toggle controls only (on=default; off=momentary/unlatched mode).
check it out!
cheers

Thanks Rui! I'll test it and report back.
The option works but it seems to work in the exact opposite way as I thought it would. Unticking latch turns my non-latching FS-5U switch into a latching switch. Ticking the box, so activating latch mode, makes it keep its non-latching behavior.
maybe we're confusing terms here:
a) re. FS-5U: the "U" is for Unlatched aka."momentary" mode of operation--should work with a MIDI controller with the "Latch" attribute (un)checked OFF;
b) re. FS-5L: the "L" is for Latched mode of operation--should go for a MIDI Controller with the "Latch" attribute checked on (as is the default as ever before).
hth.
cheers

I get it now, thanks. I misunderstood to what the term Latch applied to. It applies to the switch you're using, not an option in Qtractor itself (that was what I was refering to). So if you're using a latching switch you should tick Latch, if you're using a non-latching switch you should untick the Latch option.
I think this ticket can be closed. The latch option works great, I'm using it quite a lot at the moment. Thanks again!
