Each switch was scanned in succession by a looping machine code routine.

The board is shown here without the multiplexer chips.Ĭustom designed software on the C64 performed MIDI routing to as many as 16 different MIDI devices (percussion and synth). The 4 ins (4 bits = 16 triggers) returned data from these multiplexers. The 4 outs selected one of 4 '1 of 16 multiplexers', each capable of scanning up to 16 triggers (a maximum of 64). The port's 8 data lines were configured as 4 outs and 4 ins (8 bits). The drum triggers were made from film cans, stuffed with pieces of blanket to deaden the sound.Ħ1 trigger switches (37 keys, 24 drums) were connected via this custom Commodore 64 parallel port interface. The keyboard was removed from the Hammond Sounder and wired such that it was easily moved back and forth between the two units in a few minutes. It was easily disassembled for transporting and storage. The Hammond d'Eggs controller was designed specifically for use in live performance. Young Monkey designed back in 1988 this monster MIDI controller for the Commodore 64.

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.Īnd to finish off this MIDI retro nostalgia, check out in this pic how good the Commodore SX64 looks when racked up in a studio full of Sequential Circuits stuff !!! thanks to this photo I NEED a SX64 in my rack immediately. 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. Owing much of its design to the Six-Trak, the Max lacks pitch and modulation wheels as well as the Six-Trak's "stack" mode which allow you to stack all six multi-timbral voices for a very complex monophonic sound. It was designed to be attached to a Commodore 64 computer (one of the more music-oriented personal computers of the time). The Max is a 6-voic e, multi-timbral analog synthesizer with a 4-octave, 49-note (C-C) keyboard. This is the MAX, which stands for "MIDI Voice Expander/Computer Peripheral" and it was one of the keyboards that Sequential Circuits built between 1984-86. The channel messages can be displayed all together, or limited to any channel with a single keystroke. This is useful for finding specific activity. The space bar clears the screen and resets the graphics.

There is extensive help built in, but the operation is pretty simple. The typical application might well be to simply start MIDIMon and let it run.

Channels active since last screen reset (black).If you are not really using your Commodore right now, why not use it as a MIDI monitor for your studio ? Nothing beats a MIDI monitor on top of a rack, even if you never look at it.
