MONOTONE (.mon), Jim "Trixter" Leonard / Hornet's PC-speaker tracker — up
to a dozen square-wave tracks summed into the IBM PC's single 1-bit beeper.
Extensions: .mon
The mixing wraps the PTPlayer-style channel model; the output is a 1-bit speaker sampled to PCM, as in bbsongplugin.
Note: .mon is also a UADE extension (Legless Music Editor); routing is by
content and by plugin priority.
