Kurzweil scsi Manual Do Utilizador
want the Kurzweil to be able to access that device. The default Kurzweil ID is #6.
Macintoshes use ID 7 and SCSI cards for PCs are also normally set at 7. The
internal drive of a computer is normally set at 0. For an external drive, there will
usually be an external switch which allows you to choose the ID, although with
some drives, it may have to be done by opening the drive and changing jumper
pins. Most drives will allow you to choose any ID, although there are some which
limit your choices - for example the Zip drive only gives you the choice of 5 or 6.

You can change the SCSI ID of the Kurzweil on the MIDI Receive page, but we
recommend leaving it at 6 and changing your other devices if needed, since each
time you hard reset the Kurzweil, it returns to 6. If you forget to change it after a
reset and have a SCSI ID conflict, you can lock up your SCSI chain and forget
the reason why.

One thing to watch out for if having a hard drive installed in the Kurzweil - many
fixed drives come set with their default at 6 (the same as the Kurzweil). Make
sure your service tech knows to set the ID to a different number (this is normally
done by moving jumper pins on the drive). One curious side effect of this problem
- if the internal drive is set to the same number as the Kurzweil and you have
nothing else in the SCSI chain, then you will see the drive show up on every ID
except for its own (the Kurzweil shows up on that ID, since it is also on the ID).

If you do have more than one device with the same ID, the Kurzweil may lock up
when you scroll through the SCSI numbers in Disk mode, or if you are in a chain
with a computer, it may not boot up at all.

If you have more than one Kurzweil, they can be on the same chain and both be
able to access any drive in the chain (though not at the same time). Make sure to
change the ID on one of them.

If you are having problems getting the Kurzweil to see a device on the chain,
sometimes just changing its ID to a different number may fix the problem, even
there was no device ID conflict before. There is no logic to this phenomenon - it's
just another SCSI weirdness.

As a general rule, we recommend only changing the ID of a drive when the
system is powered off. It is possible (although unlikely) that data could be
corrupted if the ID of a drive is changed while it is turned on.

Theoretically all eight SCSI IDs can be used, however, we often hear of users
having problems with more than 5 IDs. This may be more of a result of not
following all the other rules (especially concerning cables), but some SCSI
devices seem to be picky.

We have also gotten reports from users who state that they can only get their
SCSI chain to work when their devices are hooked up in a specific order. Other
than having the two ends of the chain terminated, order should not matter, and
yet it does for some people. This may be due to impedance variations in the
various units, varying internal cable lengths, etc. The bottom line is that if you are
