C64 Ultimate: Doctor Mix Dissects the Commando Groove

First, the two rummage through the included music material on USB. Later, the online file search in the music category leads to further finds. The network access is explicitly described in the conversation as a gateway, not as unrestricted internet access. For this afternoon, something more tangible counts anyway: finding music, loading it, and working with it.

Doctor Mix already knows videos about Hubbard’s programming. But he’s interested in the arrangement: how are musical tasks distributed among the three voices, how do drums appear in them? He wants to see waveforms and be able to listen to voices individually. Instead of just wishing, he commissions Claude to write a suitable program.

The program, which according to the two was created by Claude, is finally started via the file browser. In the demonstration, it runs, voices can be muted; both celebrate this as a first-try success. More interesting than this AI euphoria, however, is what they work out with it.

When listening to an isolated voice, they describe a snare-like noise component in the attack, immediately followed by the note. So one voice rapidly takes on changing tasks, rather than simply corresponding to an instrument track. Anyone wanting to understand the groove here also has to listen to the small transitions. Doctor Mix doesn’t stay long in analysis: he mutes and unmutes voices until they’re talking about breakdowns and drops. Analytical access becomes musical intervention.

That Doctor Mix prefers to get hands-on with the C64 rather than just admire it has a concrete backstory. In his 2019 Cynthcart Megamod video, LOOK MUM NO COMPUTER builds a control panel for him: Arduino Nano, twelve knobs, and MIDI control commands for the synthesizer software. The basis is a MIDI controller tutorial by Notes and Volts, whose code he adapts.

In the demonstration, he changes pulse width and waveforms, can edit voices two and three separately, and add noise to the third. This is sound design, not analysis of a finished Commando arrangement. Practical access also has its limits: he reports an increasingly noisy filter, the cause of which he cannot determine. According to his own statements, he provides PCB documentation and adapted Arduino code for others to build.

Espen Kraft, in his C64 music video from January 2020, starts from his own song. For the new version of The Golden Boy, he develops bass and drum sounds with the MIDI software referred to as Messiah in the transcript, plays them in, and records them in the DAW. His arpeggiated bass figure doesn’t come from a fundamental love of acid: he needs it for the bridge. First the musical task, then the sound.

For chords, Kraft circumvents the limitation of the mono synthesizer module used by multitrack recording. This is not additional real-time polyphony of the C64, but studio craft: individual lines are combined in the arrangement. Where Doctor Mix makes audible how much happens within a single voice, Kraft lets several recorded voices work together.
