alphaSyntauri
Arguably the zenith of Apple II audio hardware, the alphaSyntauri system is comprised of a 49 or 61 key velocity-sensing keyboard, a set of Mountain Computer Music System synthesizer cards and a variety of waveform editing and sequencing software. In addition to the keyboard, a complete alphaSyntauri system also includes two foot pedals to control sustain and portamento, and a set of game paddles to control other effects.
By contemporary standards, the alphaSyntauri may seem somewhat limited, but its historical significance as one of the earliest home computer-controlled synthesizers is undeniable.

Mountain Computer Music System
The Mountain Computer Music System was made up of two expansion cards connected by a short ribbon cable and a "light pen" used to input notes and edit waveforms directly on the Apple II monitor's screen. The MCMS is capable of playing 8 stereo voices simultaneously, although its 8-bit digital sound may seem harsh and sterile by today's standards.
The MCMS software includes a fairly good sequencer as well as a graphical waveform editor.
