The intro and first part demonstrates the 4-channel mode, in which the engine basically acts as a Squeeker Plus clone.

In the second part, operators 1 and 2 are linked to create the phasing bass, while channel 3 and 4 make some use of the fx table feature.

In the first half of the third part, various different configurations for the two-op mode on ch1 are demonstrated, including the SID and Earth Shaker effects. The other channels are silent save for some occasional noise (this time without using tables, hence it sounds more rough).

In the second half of the third part, the single channel mode is demonstrated with 3 and 4 operators in use, and various different configurations of phase, detune, coupling mode and so on.

There's obviously no XM converter for this, so for the time being you'll have to hand-code the music in asm, like I did with this demo tune.
