Designed especially for musicians and music educators who use music CDs for accompaniment, the Superscope PSD340 featurers both a CD recording drive and an innovative MP3 CD player drive capable of real-time changes in key, tempo and voice reduction on any music CD or MP3 audio file.

This rugged and reliable music rehersal and recording tool will help anyone make great sounding CD recordings, create custom CDs, and duplicate CDs right on the spot.

Significant improvements in Superscope's real-time tempo and key change controls for CD's (and now MP3 files) mean you can slow down a song's tempo by 75% while retaining the original musical pitch.

Shift the key of any song at the touch of a button up or down as much an octave while the tempo remains unchanged. Fine tune a CD or MP3 file on a CD to match a voice or instrument. All these changes may be recorded to a new CD as a take-home accompaniment.
