FREE · FROM MY COMMODORE 64 VIDEO

Rob Hubbard’s Commando,
voice by voice.

The visualiser from my Commodore 64 video. Free.

When Cris and I unboxed the new Commodore 64 Ultimate, the first thing I wanted to do was pull Rob Hubbard’s Commando theme apart. This visualiser does exactly that, right in your browser. Load the tune and it gives each of the SID chip’s three voices its own lane, so you can see which waveform it’s using and which note it’s playing. Mute one, solo another, step through the tunes, and you can hear how Rob built a whole soundtrack out of three channels. It’s free.

THE VIDEO

Watch it work, first time.

WHAT IT DOES

Three voices. One legendary tune.

All three voices of Commando playing in the visualiser
01

SEE EVERY VOICE

Each of the SID chip’s three voices gets its own lane: the waveform it’s using (pulse, saw, triangle or noise), the note it’s playing, and a trace that scrolls across the screen as the music plays.

Voice 2 soloed in the visualiser, with voices 1 and 3 marked MUTED
02

MUTE IT. SOLO IT.

Press 1, 2 or 3 to mute a voice, or Q, W or E to solo one. Here voice 2’s sawtooth part is playing on its own, with voices 1 and 3 muted.

HOW IT WORKS

Open it, load the tune, play.

  1. Pop your email in and the visualiser opens straight away, right here in your browser. I’ll also email you a link so you can come back to it.
  2. Load your own copy of Commando as a .sid file. It plays in your browser and is never uploaded anywhere.
  3. No copy yet? Check the MUSIC folder on your C64 Ultimate USB stick, or the High Voltage SID Collection at hvsc.c64.org.
  4. Use the keys below to mute, solo and switch tunes. It works with other .sid files too.

In the video, Cris and I ran it on the new Commodore 64 Ultimate. See the Commodore 64 Ultimate →

Commando music composed by Rob Hubbard (1985). Doctor Mix doesn’t host or distribute the music: you load your own copy. The visualiser is a Doctor Mix project, not an official Commodore product.
