Using USB keyboard knobs and sliders in linux - Linux-audio-user

In my limited experience I've found that the ease of mapping MIDI controller knobs to their software equivalents varies from application to application. In Ardour, for example, one middle clicks on a screen control, say, a mixer fader and a prompt appears telling you to move the desired hardware knob. This seems to work quite well. In something like ingen or AlsaModular Synth, you have to add a module that allows reception of MIDI controller input. In AMS, there's a quad MIDI-CV module that allows you to assign four MIDI CC controllers. Hope this helps.... cheers, ernie On Thu, Sep 3, 2009 at 10:24 AM, Matt Henley <nwmatt(a)gmail.com> wrote:

I recently got access (on loan) to a Edirol PCR-300 USB midi keyboard. When I plug it into the computer it shows up under QJackCtl and is quite usable as a midi keyboard for the Synths that I use (ZynAddSubFX and AmSynth). The question that I have is that the keyboard has a full compliment of sliders, pads and rotary knobs which I don't know how to use for anything. Is there documentation on how to set these up to control parameters on software such as Ardour/Rosegarden/LMMS/Ingen? If so where would i find it? Do these controls go to midi channels and can they be assigned to OSC controls? Sorry for my ignorance, I just didn't know where to start.

At least on my system, that is Ctrl+middle click Renato

Sorry, I stand corrected. I'm a new Ardour user and have only done it once.... cheers, ernie -- ++++++++++++++++ Ernie Dulanowsky www.pulsewidth.ca ++++++++++++++++ oblique: Cascades <http://twitter.com/oblique/statuses/3730922770>

Concerning AMS you forgot to mention that you could simply use the build in "Control Center" (menu "View/Control Center), which allows to match any MIDI controller to any kind of slider/parameter and module you assembled in your patch (without using a special type of module).

Yeah! I was really happy once I found that capability of AMS! Connecting sliders and knobs works easily but as you are involved in AMS: do you know a trick to use MIDI-switches (to switch presets for instance) in AMS? best regs HZN

really delved into AMS that much, so the MIDI to CV modules were the first thing I encountered to do that function. I will definitely check out the Control Centre/Center. That will serve to clean up the few patches I've made. Thanks for this information! cheers, ernie -- ++++++++++++++++ Ernie Dulanowsky www.pulsewidth.ca ++++++++++++++++ oblique: Change nothing and continue with immaculate consistency<http://twitter.com/oblique/statuses/3730358467>

Hey Matt, One thing to note: In qjackctl, you'll notice that the PCR has three entries, PCR MIDI, PCR1 and PCR2. IIRC, one of the MIDI devices sends keyboard MIDI data, while the other sends controller (knob, slider) data. It's in the manual, I can't recall which is which, but at least you'll be on the lookout for it. :) --

hi Matt, there are applications like kmidimon and gmidimon for monitoring MIDI, they might be useful for checking the data coming from the Edirol. In the case of ZynAddSubFx there are a limited set of fixed controller numbers assigned to certain parameters, found here: http://zynaddsubfx.sourceforge.net/doc_3.html AmSynth has menu item: Config -> MIDI Controllers In Phasex: right click on parameter name It is pretty much different for each app. If translation of midi signals is required, qmidiroute or even pd (overkill but flexible) are useful. best, d
