Suzuki QChord - help filtering the midi output into my DAW 2009-03-16T20:39:38+00:00 I've got a Suzuki QChord solely for the "midi strumplate" and chord buttons. Follow that link to see what I mean. However, the midi data it sends is quite poorly implemented. I've edited the relevant information from an article by Jeff Obee in Electronic Musician magazine. MIDI OVERBOARD The Q Chord receives and transmits MIDI in Omni mode only. It transmits its various parts on 12 separate channels. For instance, the Melody Keyboard is on channel 1, Chord Plus on channels 3 and 4, and the Strumplate on channels 14, 15, and 16. As noted previously, most Q Chord sections can be turned off, but not drums-so MIDI data is constantly output on channel 10. Strangely, the Q Chord regularly sends MSB, LSB, and Pitch Bend value 64 (the middle, "neutral" position on a pitch wheel) messages on all accompaniment channels, even those that are supposed to be turned off. Presumably this data is intended to reset synth voices on all channels, but when a part is off, it ought to send no data. To top that off, when you change chords with the buttons, the Q Chord sends unexpected Pitch Bend messages in order to shift sustaining Strumplate notes to the proper pitch. (Remember, the Strumplate triggers chord tones determined by the buttons.) These Pitch Bend messages can make a non-GM synth sound drastically out of tune. Add the three channels for Strumplate output, and you have enough extraneous data to annoy the average sequencer jockey. With some effort, you can sequence Strumplate parts, even in odd meters. To sequence the Strumplate on its own, I had to turn down the drum part (turning down the Rhythm volume on the Q Chord sends CC 7 messages to the GM module) so I didn't have to listen to it. But I was still forced to remove the superfluous drum, Pitch Bend, and other data recorded to the sequencer. Jeff Obee is a San Francisco Bay Area-based composer and producer who plays the synthesizer and fretless bass. What can I use that'll most efficiently filter out all the useless midi data so that the chord buttons and strum plate can be used to play VSTi in my DAW? I use Usine so modularly routing midi data isn't a problem. Thanks in advance for any help. If I get it working the way I want I'll post files to help other QChord owners utilize them as a controller for VST instruments. runagate https://www.kvraudio.com/forum/memberlist.php?mode=viewprofile&u=41055

Sorry for reviving this thread again

. I've had a qchord for about a year or so and it just occured to me to try hooking it up over midi. I am using a y-cable (midi in + midi out > usb) to go into my computer (windows 10). it shows up in the device manager, and in midi ox, but i am getting absolutely no data sent from the qchord to the computer. I only have the midi out plugged into the out (and the in left open as per the manual), but i have tried every combination and can't get data to show.

I am very new to the world of DAWs and midi input devices, but I am struggling to figure out what i'm doing wrong. I understand this device sends midi over the channels in a funky way, but i should be getting too much midi data...not none at all!
