The Micro Synthesizer can create many of the most popular analog lead synthesizer voicings at a fraction of the normal cost for such capabilities. Its four voices: GUITAR, OCTAVE, SUB-OCTAVE, and SQUARE WAVE are completely independent and fully mixable. The MICRO SYNTHESIZER can modify these signals with envelope control for a variety of "bowed" or "blown" sounds. In addition, a sophisticated swept filter control allows highly variable frequency adjustments to be made to the signal. When combined, these controls offer the user a creative capability that is virtually limitless.
