Yamaha CS70M Dual Channel Polyphonic Synthesizer

   (0 reviews)

The Yamaha CS70M programmable dual channel polyphonic synthesizer offers full six-voice polyphonic capability, an internal memory system capable of storing up to 30 sounds, a built-in magnetic card reader / writer that provides unlimited external sound storage capacity, and a sophisticated built-in polyphonic sequencer.

In addition to these extraordinary features the CS70M has a full complement of sound parameter controls, many of which are remarkably innovative, and an extensive range of effects. Just a few moments at the CS70M's keyboard will convince you of the enormous expressive potential it offers expressive potential and creative freedom so vast that your musical scope will never be limited.

Conventional non-programmable synthesizers are fine for studio work, but they tend to limit your flexibility on stage due to the time required for re-patching whenever a new sound is needed. The CS70M lets you pre-program up to 30 separate voices, each comprising 39 voice parameters, for instant recall during performance at the touch of a button.

It also incorporates a magnetic data card system that provides literally unlimited storage capacity. Sounds you create with the voice parameter controls can be digitally stored on external memory cards, and then later reloaded into the internal memory.

The built-in 4-bank polyphonic sequencer can be valuable as an extra pair of hands in live performance situations. It can record up to 4 independent note sequences exactly as played with six-note polyphonic capability.

The CS70M has an extremely sophisticated split keyboard system. It features a program-mable split point, the capability of playing different pairs of voices on the two sides of the split, and a split balance control.
