Alesis Q and QX Series - Troubleshooting USB Connection Issues

alesis qx49 main2The Alesis Q and QX series controllers provide incredible control of MIDI mappable DAW and plugin environments without the necessity of drivers.  This tutorial explains how to troubleshoot USB connection issues with the Q and QX series keyboard controllers in the Windows and OSX environments.




Getting Connected

Make sure that the USB cable is plugged firmly into the USB port on the rear of the Q or QX keyboard.  The other end should be firmly plugged into the computer's USB port.  On desktop computers, rear USB ports are preferable as front ports may not meet the power demands of some bus powered devices.

The Alesis Q and QX series USB MIDI keyboard controllers are class-compliant. This means that they do not require any separate software drivers to be installed, but use generic MIDI device drivers built into the operating system. When connecting your Q or QX series keyboard via USB, both Windows and Mac computers automatically recognize it, install the generic MIDI device drivers, and make it available to use. This is the very definition of "plug and play."
