For MIDI composers and musicians using controller keyboards, the QSR™ offers the excellent sounds and powerful synthesis engine from our advanced QS7 and QS8 keyboards in a single-space, rack-mount module. 16 megabytes of great Alesis sounds are packed into the QSR, and you can easily expand its sonic library by plugging in a QCard. Plus, the QSR offers the same dual expansion card slots, serial port and CD-ROM software package as the QS Series keyboards, making it one of the best values today in professional-quality sound generation tools.

• The QSR is a single rack-space module version of the QS7 and QS8. It has all the sounds, features and interfaces of the QS7 and QS8 with the exception of the keyboard and the master controller section.
