Hey Mac,
I just read the article and learned how to get into the IRQ list and I think I solved the problem.
The only conflicts I found were on my PCI card for my USB slots
VIA rev 5 or later USB Universal host controller is what it is coming up as.
I have 4 usb slots on this card.Two of them are on address 3 and two of them are on 5
then the same thing shows up again with two slots at address 12.
I'm thinking these are not on the card itself and are the ones for my computer keyboard and mouse.
All the card slots are full. An air card for my web access, my printer, my Tascam US428 control surface and finally a USB hub with 4 extra slots,which are not currently used.
I had the Tascam contoller and the Aircard on slots 1 and 2( sharing the same address I assume), followed by my printer and the USB hub.
I put the Air card onto slot 3, so that it is a different address from the Tascam and that did it.
I had another sequence (Lightyears,Chick Corea) with a lot of pitch control events for the guitar and sax tracks.That was unplayable before and I thought that it might have been a bad sequence, but that plays OK now too.Amazing how one little thing can mess up so many seemingly unrelated functions
So thank you Mac for pointing me in the right direction.I could have never figured this out on my own!
