In the tracker RED, the last 2 digits (HEX) of each note indicates how the note is played.

This 2 digit-code is called the 'effect'. Besides playing a note 'normally', there are effects
for volume manipulation, vibrations, slides, arpeggio-effects, PSG-drums and much more.


In code (REPLAY.GEN), every effect is described in a 'kind of' declarative way
(see labels 'EFFPSG??' and 'EFFFM??').

For example (see also image 'PSG_and_FM_effects.png'):

Function of effects
===================
Examples of simple basic effects:
- Effect '03' just plays the note (in code, see: EFFPSG3 / EFFFM3).
- Effect '04' plays the note and also sets instrument & volume (in code, see: EFFPSG4 / EFFFM4).
