The Xpander is a six-voice desktop version of the Matrix 12 with which it shares an identical voice architecture. In many ways they are the most flexible non-modular analog synths ever built.

Extended information

Each voice has five LFOs, each with about five different wave shapes, plus the ability to sample most other modulators; five envelopes that can repeat themselves, sync to an LFO, and so on; a lag processor (like portamento, but more general); 3 tracking generators (that apply a series of linear functions to a value over its range); some ramp generators (the attack portion of an envelope); a 15-mode filter and a user interface to make all of this accessible.

You'll also find six additional individual outputs and an external audio input which can be routed through the filter. Another very useful feature is its MIDI-CV/gate conversion capabilities that the Xpander offers for external control of other synths. It can convert 8 voices of these control signals, which output standard 1V/8va CV and positive gating. And like The Matrix synths, the Xpander sounds wonderful, capable of thick analog basses, pads and textures.
