VI49 with Ableton Live: Undesired notes when triggering

Hi!

I use the drum pads and keys of a VI49 with Ableton Live to trigger audio files and MIDI notes. I really feel it was doing all fine for a few years but recently, when a press a key to trigger a sound, that sound starts but also a long undesired grand piano note corresponding to the note I played. It's like there was an other MIDI piano track, but there is none.

It's strange because the sound doesn't even appear on any the vu-meter but I hear it lound and clear. Is there a setting I changed without realizing? Have you heard of that problem before? I'm on a Asus, Windows 10. I have a feeling it may have started when I changed my computer but I don't see how to make it stop.

Thank you very much.

Hey Vegetarium,

Thanks for posting!

We can verify whether your VI49 is sending the correct MIDI data to your computer with MIDI monitoring software. A MIDI monitor will show you all the incoming data from any MIDI controllers or MIDI interfaces that you have connected to your computer.

For testing MIDI devices on PC:
Download MIDI-OX

This video will get you set up quickly for MIDI input monitoring in MIDI-OX:
Monitoring MIDI Input with MIDI-OX

For testing MIDI devices on Mac:
Download snoize: MIDI Monitor

Select the VI49 as a MIDI input source in the monitor and send some data with its keys and controllers. If you see data appear in the input monitor window that does not correspond to the key that you pressed then the MIDI module is sending ghost data and will need to be repaired.

Try this and let me know how it goes!

Hi Eliza,

Thanks a lot for responding me.

I used MIDI-OX as you suggested me. From what I know it looks coherent. When I press a key, there is only a note on a the right pitch that goes on. The corresponding note off writes itself when I release. There's no other data being writen.

Also, I also made some tests to see the extent of the problem. In Ableton Live, I tried to trigger sound files with knobs, on/off buttons and even the pitch wheel and there where no undesired notes (I also tested these buttons with MIDI-OX). But, when I associate a trigger with a keyboard (or drumpad) key, those parasite piano notes are played when I, for instance, click the stop button, create a new track(!) or even close the software(!!).

If you have an other cue, thank you. :)

Hello, Vegetarium

This controller does not have any internal sounds. It is triggering something thats opened on your computer, perhaps there is another software open in the background that is causing a piano sound to trigger. Also, make sure there are no MIDI tracks record enabled, that would stop any MIDI from triggering a MIDI track in your project.

Hope this helps!

Hi Criss,

Thanks for that idea, it sounds logical. Apparently the sound's produced by Live. That is what my computer mixer shows. And that's strange because, in Live, on the master vu-meter, it doesn't show like any sound is being produced.

For instance, I trigger a track wich starts with few seconds of silence; I hear the intruding note when I press the trigger but it doesn't appear on the vu-meter, then the music starts, as supposed, and appear normally on the vu-meter. I'll try to find where is that secret layer that appears on my computer mixer but not in Live.
