Troubleshooting
General
Here are answers to common questions you may have, using your Q88 MKII keyboard:
Problem 1: My Alesis hardware suddenly stopped working after having performed fine
since installation.
Solution 1: Switch off the unit and let it sit for 10 seconds. Then restart your computer and try
again.
Problem 2: I have plugged a sustain pedal into my Alesis keyboard, but it works the
wrong way around.
Solution 2: The polarity of the sustain pedal is calculated by the keyboard when it is powered
up. On power up, the sustain pedal is assumed to be in the OFF position. So if you want the
sustain pedal to be off when it is not depressed, make sure the pedal is not depressed when
you power up.
Problem 3: When I press a key, there is a delay before I hear any sound.
Solution 3: This delay is known as latency. Latency with MIDI signals is due to the software
application you are using. MIDI data is simply control data. The MIDI data is read by your
software. The software then completes a large number of complex calculations in order to
produce the sound you hear—all this takes time.
We strongly recommend a proper audio interface. Refer to alesis.com for a selection of
options. If you already have an adequate audio interface, try reinstalling the latest drivers for
the audio interface, or try reducing the buffer sizes of the audio drivers.
