autochords

This special feature is dedicated to what SounDemoN once called "autochords" and which is an attempt to achieve chord-like effects using a single SID voice that is frequently updated. While different songs may be using slightly different approaches, the implementation usually resembles that of a digi-player in which waveform settings are changed via some well timed NMI.

Contrary to regular songs which update SID registers rather infrequently (e.g. 50 times a second) respective register updates here are sometimes only a few clock cycles (1MHz) apart - which means that respective songs use up a more significant portion of the available CPU cycles while also depending on very precise timing.
