Hi folks,
If this seems like a stupid question, it's because I'm very new at this.
Is there a way to control the jack transport system start/stop with a
hardware controller or footpedal? I want to control jack, thereby
controlling other jack aware applications which do not have
implementations of start/stop via midi.
USB keyboards are cheap (I'm talking about the qwerty kind). Inside is a
tiny circuit board and lots of switches. Figure out the lines that go to
the space, left arrow, right arrow (or whatever you think would be
useful). Most programs will deal with key strokes. If you want it to be
separate from your desktop KB there are ways of doing that probably in X
or use a raspberry pi and run netjack and jack_transport or
jack.transport... Or no jack at all on the pi and just have it ssh into
your computer and run jack_transport.

New subject: hardware midi control--footswitch? or Jack audio transport
Btw. another issue might be that the OP perhaps wants one foot switch to
start and stop, but the quasi default is that there are different
switches/commands for start and stop and stop might provide an option to
continue playing from the start position. So preparing a qwerty-keyboard
might need a script to change the command between play and stop after
each usage of the footswitch.
Do those USB MIDI foot controllers work with Linux, IOW is it possible
to allocate MIDI commands to the switches, without the need to run
Windows/Mac software for doing this?

It's less expensive to buy such a device instead DIY.

I found out that some don't need a driver, so they should work for Linux
too, assumed there's no need to send a special command. IMO a command
could be transformed to another and I guess some apps allow to allocate
MIDI commands to the software's knobs.
