SCSI Guidelines
The following sections contain information on using SCSI with the K2600, as well as speciÞc
sections dealing with the Mac and the K2600.
Disk Size Restrictions
The K2600 accepts hard disks with up to 2 gigabytes of storage capacity. If you attach an
unformatted disk that is larger than 2 gigabytes, the K2600 will still be able to format it, but only
as a 2 gigabyte disk. If you attach a formatted disk larger than 2 gigabytes, the K2600 will not be
able to work with it; you could reformat the disk, but thisÑof courseÑwould erase the disk
entirely.
Configuring a SCSI Chain
Here are some basic guidelines to follow when conÞguring a SCSI chain:
1. According to the SCSI SpeciÞcation, the maximum SCSI cable length is 6 meters
2. The Þrst and last devices in the chain must be terminated. There is a single exception to
3. Each device in the chain (including internal hard drives) must have its own unique
4. Use only true SCSI cables: high quality, twisted pair, shielded SCSI cable. Do not use
(19.69 feet). You should limit the total length of all SCSI cables connecting external SCSI
devices with Kurzweil products to 17 feet (5.2 meters). To calculate the total SCSI cable
length, add the lengths of all SCSI cables, plus eight inches for every external SCSI device
connected. No single cable length in the chain should exceed eight feet.
this rule, however. A K2600 with an internal hard drive and no external SCSI devices
attached should have its termination disabled. If you later add an external device to the
K2600Õs SCSI chain, you must enable the K2600Õs termination at that time.
ThereÕs a switch on the rear panel of the K2600, which you can use to disable the K2600Õs
termination. We recommend, however, that you leave this switch set to Auto , which
enables the K2600 to switch termination on or off depending on your SCSI conÞguration.
Poor termination is a common cause of SCSI problems. Having more than two terminators
on the bus will overload the bus drivers, but this should not cause permanent damage to
the hardware. Poor termination can corrupt the data on your disk, however, as can bad
SCSI cables.
A note about active termination: The K2600 uses active termination of the SCSI bus.
Active termination has some beneÞts over traditional passive termination. Some people
view active termination as a cure for all SCSI problems, but this isnÕt true. Active
terminators are appropriate at the end of a SCSI chain. All APS SR2000-series external
drives use internal active termination that can be switched on or off.
SCSI ID. The default K2600 ID is 6. Macintoshes
RS432 or other nonSCSI cables.

    MIDI, SCSI, and Sample Dumps SCSI Guidelines computer memory can easily be corrupted. You may not know that damage has been done to these bits until unexpected things start to happen for no apparent reason. 13. A good way to verify your SCSI hookup is to save and load some noncritical Þles. K2600 and Macintosh Computers There are several points to consider when using a Macintosh with the K2600: 1.
  • Page 4: Loading Samples With The Midi Standard Sample Dump

    MIDI, SCSI, and Sample Dumps The MIDI Sample Dump Standard The MIDI Sample Dump Standard Samples can be transferred between the K2600 and most other samplers and computer sampling programs using the MIDI Sample Dump Standard. Due to the relatively slow transfer rate of MIDI data, transferring samples into the K2600 via the MIDI Sample Dump Standard can take a long time, on the order of a coffee break for a large sample.
  • Page 5 MIDI, SCSI, and Sample Dumps The MIDI Sample Dump Standard program canÕt transfer samples at numbers greater than 128, specify number 19 (ThereÕs an exception to this; please see Troubleshooting a MIDI Sample Dump on page 6-6). At this point, youÕre ready to try loading a sample. See Accessing a New K2600 Sample on page 6-6 to learn how to use samples once theyÕve been dumped to the K2600.
  • Page 6: Accessing A New K2600 Sample

    MIDI, SCSI, and Sample Dumps The MIDI Sample Dump Standard Accessing a New K2600 Sample First, select the K2600 program you wish to play the new sample from, and press Edit . Then select the layer you wish (using the Chan/Bank buttons if necessary), press the KEYMAP soft button, and select a keymap.
  • Page 7: Aborting A Midi Sample Dump

    MIDI, SCSI, and Sample Dumps SMDI Sample Transfers would ordinarily dump a different sample from the one you intended, possibly causing the dump to fail. The K2600 automatically counteracts this offset by adding a number to sample requests. This was done because more sample editing programs create this offset than do not. If you Þnd that the K2600 is sending samples with higher IDs than the ones you requested, you can compensate by requesting the sample ID one lower than the one you want.
