USB-Midi Software
Note : (to work without gdm) : nmtui is the terminal wireless manager
Install the alsa-utils package.

- If needed, insert module manually, only since the 3.19 kernels and following:
# modprobe snd_seq_midi
- Check loaded USB Midi module:
# lsmod | grep snd_seq_midi
- Check your hardware, for presence:
$ lsusb $ amidi -l $ aconnect -i or aconnect lio
- Check your hardware, for actual input:
$ aseqdump -p ##
(where you should replace ## with the client number of your keyboard from aconnect -i)
IF you're not already on Pipewire, but still on Jack: (but you should be on pipewire)
- Create connection in patchage:
$ a2jmidid -e
(After starting jack)
USB-Midi Hardware
The Ubiquitous Korg:
http://www.korg.com/us/products/controllers/nanokontrol2/ 0944:0117 KORG, Inc. nanoKONTROL2 MIDI Controller
The Korg Setup software is an .exe, but works with wine
The new MIDImix from Akai works great !
The setup software works with wine.
The Hungarian Pedal:
http://www.ebay.fr/usr/guitar.fun.stuff?_trksid=p2047675.l2559
is on the Linux-USB list of vendor IDs
http://www.linux-usb.org/usb.ids
as:
05e4 Free shared USB VID/PID pair for MIDI devices
and returns here as it should as:
ID 16c0:05e4 Van Ooijen Technische Informatica Free shared USB VID/PID pair for MIDI devices
The short manual on the ebay page reads as follows:
Plug and play, no driver or installation needed. Just plug it into a free USB slot and your OS will recognize it.
Choose USB Midi device in your software settings and you're ready to go.
Two controller mode:
* Mode 1: Changing whole presets. The controller sends program change messages.
The LEDs indicates which preset is working.
* Mode 2: To activate this mode, press buttons 2&3&4. To change back to mode 1, press buttons 1&2&3
(All LEDs will blink for half a second to indicate this).
In mode 2 the controller sends control change messages. It allows you turn functions/effects on and off individually.
The LEDs indicate their status.
In mode 2, press a button for 10 seconds to switch to momentary mode. (All LEDs will blink for half a second to indicate this).
It allows you to use non-on/off functions like 'previous/next preset', 'tape deck play' etc.
The LEDs do not light up in momentary mode since it's unnecessary.
External pedal input. You can connect any standard pedal with a 6.3mm (¼ inch) stereo jack. Using an “insert” or “Y-shaped” cable.
To use the full range of the pedal you may have to calibrate it.
Calibration: Step 1:turn the pedal to minimum position and press button 1 AND button 3.
(All LEDs will blink for half a second to indicate this).
Step 2:turn the pedal to maximum position and press button 1 AND button 4.
(All LEDs will blink for half a second to indicate this)
The device will save the calibration data so you only have to do it once.

The Full Monty: HungarianPedal + IDJC + D::Light/Whitecat
AKA Show Control with USB MIDI Footswitch MIDI Foot Controller with external pedal input -> Sound output AND light cues. With ONE foot
WILL NEED ALSO: a2jmidid qmidiroute and Patchage
0. Set your pedal's keys to Note/Momentary as described above.
1. We'll need the a2jmidi daemon to Create IDJC midi connection in patchage; it will only load if Jack is already running,
the easiest is to start jack, by, i.e.... Starting idjc! Then, do:
$ a2jmidid -e
2. Now start qmidiroute, and create the inputs/outputs pairs needed like this (or load them if you already did):
This is to "speak" a language D::Light understand, since it doesn't do Go on ControlChanges, and receive all 4 ProgramChanges from the pedal as the same event
Hit the "Add New MIDI Route" yellow button on top to create a new tab; Set input to "controller" Set Channel to 1 / 16 Set Controller to 0 / 96 (that is the value of the first button) Leave Value to 0 / 127 Set Output to "Note" Set Channel Offset to 0 (Change this only if you have multiple devices to which you cannot set the channel manually) Set Note Offset to 0 (This way, the former CC signal is transformed into a Note signal, but still is patched to 96) Set Velocity at 0 / 127 Leave ALSA port to 1 Hit "Duplicate" and do the same with Controller to "97" Save your map!
3. Go back to Patchage, after successful launch of the a2jmidid -e daemon, and with qmidiroute running, do:
hit Ctrl-G to re-arrange the view, and now connect the following:
From the the a2j Output box (Left one): The RED output labelled: "USB Midi controller[XX](capture): USB Midi Controller MIDI 1" Goes to BOTH: in the idjc input box (right one) * RED midi_control (You may have to re-launch IDJC if the red midi_control input is absent) in the a2j input box (right one) * RED qmidiroute[XXX](playback): in
4. Configure D::Light
In D::Light / Setup, refresh the Midi section with the blue arrows and select "Out1" In D::Light / Midi, you should see the output when you hit button 1 or 2 of the pedal; assign them as you wish.
5. Do the same with IDJC, assign keys 3 and 4 to your liking.
Note that the "HungarianPedal" has many versions with much more, or sturdier, buttons
The Full Monty: Start from Cold
To get IDJC + Whitecat or D::Light running with cues triggered from external USB-MIDI hardware
Don't plug nothing. Start qjacjctl with scripts to modprobe snd_seq_midi before start, and to start the a2jmidid daemon with the -e option. Start a terminal, check that snd_seq_midi is loaded with lsmod | grep snd_seq_midi and that a2jmidid and jack are running with ps -a | grep ... Start qmidiroute, load your needed preset translating CC into notes, and activate them. Note to Self: With the "activate" button, idiot. Start IDJC Plug hardware. Back to qjackctl, built or re-call if saved previously the needed patch connections in the patchbay, from hardware to IDJC and qmidiroute in the Midi Tab Start Whitecat / D::Light etc. You are now allowed to breathe again.
