Excelling at simple brassy sounds they we also capable of a wide variety of sounds (which was surprising as it was a single oscillator per voice synth). Sequential Circuits released the Six-Track and their Max synths which featured MIDI and the 6-Track had the ability to layer sounds. In an effort to cut costs and to appear more modern synths started to lose their one knob/slider per function opting instead for an edit one function at a time. Yamaha had exploded onto the scene with their DX7 and everyone wanted one but gigging musicians still needed some of those trusty analog sounds, especially if they were a cover band. The search for something more realistic paved the way for experimentation with various forms of digital synthesis. In 1984 keyboard & synth players were continually looking for something new and many were beginning to grow tired of the old analog sound.

The back panel features a power switch, a power-in jack (8V AC), two 1/4' jacks for stereo out, MIDI IN and OUT jacks, two 1/4' audio output jacks, and a Stereo 1/4' main output jack, which doubles as a headphone out.Sequential Circuits Six-Track/MAX Samples The Max can also be programmed using the Six-Trak keyboard or the Prophet-T8. Programming is accomplished using proprietary software for the Commodore 64 personal computer. On the front panel is a single keypad, a single volume knob, buttons for transpose and tune, and 16 buttons used to operate the sequencer. However, it does not have a MIDI Thru jack. It can send and receive on any MIDI channel and features Mono mode, MIDI program and sequence dumping, and switches to enable it to receive program changes and external wheel receive. The Max's MIDI implementation is pretty good for its time. However, when you turn it back on, you can choose from two demo sequences permanently stored in the Max's memory. Once you shut the Max off, your sequence is lost unless you back it up via MIDI dump. The sequencer features real-time recording (although it has no click-track), looping, and once you assign it to a voice, it will play independent of the rest of the keyboard. It has an onboard sequencer, which has a 500 note maximum. It was designed to be attached to a Commodore 64 computer (one of the more music-oriented personal computers of the time). Background: The Max is a 6-voice, multi-timbral analog synthesizer with a 4-octave, 49-note (C-C) keyboard.

Great working condition and no major cosmetic flaws.
