I may be completely mistaken about this, but this is how I remember voice
 allocation working on the 6r.
 When you play a note, and then repeat that same note the 6r plays that note
 on the exact same oscillator that it did previously until more than six
 notes are played, in which case it will shift to another note for that
 oscillator. What this implies to me that in playing twelve notes the first
 six will play on the first machine and then the next six will play on the
 second machine, just like this is a twelve note polyphony machine. I of
 course may be mistaken, since I didn't know it had this mode, much less use
 it at any time.

 Subject: [oberheim] Matrix 6R Spillover vs. Matrix 1000 Group Mode
 Hello, I am a new Matrix 6R owner, and I want to expand it to 12 voices by
 adding another unit. I have read that the 6R and 1000 sound slightly
 different (though this is highly contentious) and I want to minimise that
 difference as much as possible when using two units together, obviously.
 So, I have a choice between the two to buy, they both seem well priced, so
 that is not a factor, nor is the extra space taken by the 6R. What I want to
 know about is how well each of the "added polyphony" systems work, and if
 one is superior to another. I must admit that I much prefer the idea of
 alternating notes that adding the 1000 would bring (I understand that I
 would need to have the 1000 chained first as the "master" in this
 situation). But how well do two 6Rs work together
Once the maximum 6 voices
 is reached it spills over to the second unit, but I'm not sure if this will
 happen simply at a note off message (which is undesireable) or after the VCA
 envelope release frees the voice. Basically I'm concerned that I'll be
 playing say, all six notes, with a long release, lift my hands to play
 another six notes and it will play the new chord on the same machine because
 all six note-offs have been receieved, the effect being that the release
 will be cut on the first chord, rather than switching to the second machine
 to play the second chord, as the first plays out on the first machine.
 Any advice is greatly appreciated! Sorry to jump straight in with a
 question, but I need to know, and this seems like the best place there is!
 Also, I'm very happy to see that BCR2000 template in the files section -
 can't wait to try that out!
 Cheers, Fylthy
