- When I play the Triton, I can hear it, but Digital Performer can't
record the notes.
Make sure you have a record-enabled MIDI track in Digital Performer.
Make sure the pushbutton on the front of the MIDI interface is in the
- When I'm recording a track in Digital Performer, I hear two sounds
when I play a note, instead of the one sound that I want.
Turn off Local Control on the Korg.
- When I click on the Default Patch column in Digital Performer and
choose a bank, the menu of patches covers the menu of banks, so that
I can't change banks.
Move the Tracks window to a different part of the screen and try again.
This should cause the patch menu to pop up without covering the bank
- When I play my sequence in Digital Performer, I don't hear the
sound of any Korg tracks.
This could be due to any number of problems. Here are a few common
- Are the Korg and headphone amp powered on?
- Is the volume slider of the Korg up? How about the volume
knob of the headphone amp?
- How about your headphones? Do they work at another station?
- Try plugging your headphones into the Korg's headphone jack
(front left corner of the synth). If that works, then there
is a cabling problem with the headphone amp, which you should
report to me.
- Look at the list of tracks in the Digital Performer Tracks window.
Do any of the Output Device names appear in italics? (These
names are in the column labeled OUTPUT.) If so, it
probably means there is a communication problem between the
computer and the MIDI interface. Report this to me. You can
often fix this by unplugging the USB cable from the MIDI interface
and then plugging it back in.
- When you play the sequence, does a green light on the MIDI
interface flicker? If not, there might be a MIDI cable problem.
Please report this to me.
- How do I add new tracks in Digital Performer?
Project > Add Track > MIDI Track (or choose whatever kind of track
- When I change a patch on one track in Digital Performer, another
track changes to the same patch.
Make sure that the tracks have unique MIDI channels (e.g., "Triton Le-1"
on the OUTPUT device pop-up menu for a track). Note that when you
add tracks (using Project > Add Track > MIDI Track), the new
track uses channel 1, which another track may already be using.
- When I try to save my Digital Performer project, I get a message that
mentions error number -5000.
This is because you're running your project from the server — that
is, the file you opened is on the server, instead of on your local
computer's hard drive. You can use the Save As command to save your file
onto the Desktop. In the future, always copy projects from the server to
the Desktop before opening them.
- I'm trying to play sounds in Reason, but I don't hear anything. My
Reason rack is set up correctly.
Make sure Digital Performer is not running. (Check the Dock at the
bottom of the screen — there should be no DP icon.) Or, set up
Digital Performer to communicate with Reason, as described in the second
part of Exercise B.
- I'm trying to load a sound file into the Reason sampler, but Reason
refuses, saying the file is in an unrecognized format.
Open the file in QuickTime Player (available from the Multimedia menu in
the Dock). Use File > Export, and choose Sound to Wave
from the Export pop-up menu. Set Desktop as the
destination for your file, and press Save.
