Here are a few pics of my Song producer setup.
It should be noted, the song producer is not a MIDI to CV unit. It can
output 8 analog drum triggers with no velocity, for use in MIDI sequences.
Or in sync mode it can divide an incomming clock out the 8 outputs.
Or the MIDI command mode for program control of a MIDI synth setup.
Incluning splits, program changes.
Using a Commadore SX-64, a portable self-contained C-64.

Here is a typical setup, using a Drumfire analog drum synthesizer.

The Startup menu.

The drum edit screen.

The MIDI command screen.

The Sync command screen.

Moog Songstepper message.

Very advanced for 1984, but today?
