Moog Sonic Six

Because of its portable design and built-in speaker, the Sonic Six was widely used for lectures and educational purposes, often by Bob Moog himself.

[1] The Sonic Six is the result of Bill Waytena, then the owner of synthesizer manufacturer Musonics, acquiring R.A. Moog Inc.

[2] The Sonic Six is mounted in its own briefcase; the upper control panel folds and latches over the keyboard to ease transportation and storage.

This feature was used by a number of synthesizer manufacturers of the time, however the Sonic Six was Moog Music's only product that incorporated this into its design.

The Sonic Six is also the only Moog synthesizer that featured a built-in speaker rather than requiring the user to use an external amplifier.

The Sonic Six features two VCOs with changeable waveform (sawtooth, triangle, square, pulse), one low-pass VCF, a VCA, two multimode LFOs for modulation and a 49-note keyboard.
