Matrix 6, keys die then come back to life

Matrix 6, keys die then come back to life

2012-07-18 by sloppyjoe6412

Ok, now that thanks to this group I got my long neglected Matrix 6 to work, I've found stuff I didn't know before, and I'm not sure whether it's a problem with mine or just a typical feature.

With some patches, especially leads, after playing a fast sequence, one key will "die", meaning it won't respond for a while, as if the contact was gone. Of course this could be just a dirty contact going on and off. But I don't think so because after changing the patch the same key will respond perfectly well, and then next time a completely different key will temporarily die. And so it goes. It seems to affect any of the 61 keys. 

It can't be cutoff after exceeding the six voice limit because it also happens with mono patches. Plus, when you use too many fingers in a chord one or more notes will cutoff but will come back to life immediately after youi lift enough fingers: in this thing I'm describing the given key stays unresponsive until you change the patch, even if you're not playing anything else.

Also, this does not happen when I play slow chord changes. Only with fast fingering riffs, mono or chords. 

Has anybody seen anything like this?

Thanks!

does this happen when triggered from MIDI?

Have you done a voice calibration?  This kind of thing sound like a voice allocation problem. Can you get it to do this on every six key presses counting from when you first get a silent key?

I found that re-seating the ICs in their sockets took care of a mis-matched filter problem.
 
Perhaps it's just a tarnished contact on one of the IC pins that's causing an intermittent problem like this.
 
At any rate, it couldn't hurt to open 'er up, make sure that all the ICs are firmly ensconced in their respective sockets, and see if that helps.  One thing though - It would be best if you were grounded through a grounding strap, so as not to accidentally fry any chips!
 
HTH,
