While waiting for the expresion pedal and footswitch extension for MOD Duo to finally be ready for shipment , I felt curious about using my Native Instruments Rig Kontrol 3 ( foot pedal controller/audio interface ) to accomplish a similar task but instead of connecting via Control Chain like the two above mentioned, I thought it should also work well by sending Control Change MIDI messages from Rig Kontrol ( when put in MIDI Mode ) to the MOD, through a simple DIN type 5-pin connector MIDI cable between them ( Rig Kontrol Midi-OUT --> Mod Duo Midi-IN jack ).
Note: Though, as some of you may already know, the Rig Kontrol 3 is really meant for both tasks: a hardware footpedal controller and also an external audio interface to connect your instrument and amp, I am only interested here in the Controller part, consisting of 9 foot switches, one expresion pedal, and the MIDI In and MIDI Out pair of DIN 5-pin connectors, but NOT the audio interface part: analog input and oulput 1/4" jacks, volume and gain knobs, and so on… Only want to actuate the pedal and foot switches and get them to send the corresponding MIDI orders to control the virtual pedalboard running on the MOD Duo.
After configuring Rig Kontrol on Windows with NI Controller Editor software and then assigning the pedal and the switches to different plugin parameters on the MOD Web UI by using MIDI Learn, all seems to work fine : the Rig Kontrol sends MIDI messages to the MOD Duo and the parameters assigned changes as expected… Hurrah!!!
The problem that I did not imagine in the begining, comes when you want to get rid of the PC and only keep Mod and Rig Kontrol for a gig or stage situation: Sadly, the successful situation described above only works as long as the NI Rig Kontrol is plugged by USB cable to the computer: not only for powering itself via USB ( that could be resolved getting the 5V power from somewhere else, of course , and not the PC ) but because it seems the controller configuration ( the CC midi numbers assigned to each switch and to the pedal on the Rig Kontrol 3 ) is kept in by a software that runs on the PC itself ( precisely the “NI Hardware Service”, run as a Windows service ). In fact, you dont even need to really disconnect the USB cable in order to render the Hardware Controller useless: it is sufficient just to stop for a moment that service on the local services console, which causes the Rig Kontrol to leave out of “MIDI Mode” ( normally displayed as “CON” on the 7-seg LED Display on top ) and all indication lights go off … If you restart the asociated windows service ( while the USB cable remained plugged all the time ) the lights return along with the indication “CON” on the hardware controller LED display and everything goes back to normal…
My question is: Could it be some way to force the Rig Kontrol to stay on MIDI Mode while disconnected from PC ( though may be still connected to Mod USB Host port A instead ) ?
Would it be too difficult for Mod Duo to replicate the task performed by the NI Hardware Service that runs on the PC and monitors the harwdare via USB ?
Or I will always need to carry my PC in order to use the Rig Kontrol as a MIDI Controller ?
I fear I know the answer, but at least I would like to hear some of your opinions
