932 Troubleshooting

synthesizer, you need to 1) check that your instrument is able to receive

MIDI data on multiple channels, and 2) configure your instrument to play a

different patch on each channel (this is called Multi Mode on many

instruments). See the documentation for your instrument for more

information.

Another possibility is that you are playing back a GM (General MIDI)-

authored MIDI file on a non-GM compatible device.

My Keyboard Doubles Every Note I Play

When your keyboard doubles the notes, each note seems heavier or thicker

than usual, as if two notes of the same pitch are emitted when you press

the key. Also, you may find that you can play only half as many notes at one

time before some of the held notes drop out.

This can occur when MIDI echo is enabled. The keyboard plays the note for

the key you’ve pressed. At the same time, the note is sent through the MIDI

interface and echoed back to the keyboard, where it is played a second

time.

The best way to resolve the problem is to disable Local Control on the

keyboard, following the instructions that came with the keyboard. This stops

the keyboard from playing independently. The keys you play still produce

sound on the keyboard because they are echoed back by the MIDI

interface. In many cases, SONAR disables local control automatically when

the program is started, but this is not always possible.

It’s also possible that your keyboard is transmitting information on two

channels at once. To see if this is so, create a new project and record two

notes from the keyboard. Then look at what you’ve recorded in the Event

list view. If you see four notes displayed instead of two, then your keyboard

is transmitting on two channels. See the documentation for your keyboard

to learn how to correct the problem.
