Mod

Mod to vectrex conversion is not an entirely trivial thing. Here a couple of notes:

• ←the orginal MOD has 4 voices (later versions can have even more than 4)

• →vectrex only as 3 voices

• ←MODs play samples

• →although vectrex can be brought to play samples, it is not its "natural" cause (unlike theg good old Amiga), therefor vectrex will play generated sound after conversion (not samples)

• ←because MODs play samples there is no way to "auto-map" one instrument (sample) to a PSG setting (something instrument like), since every MOD can have different samples

• →not all samples have a "fitting" counterpart in vectrex "instruments".

Therefor:
In order to achieve conversion results which are at least somewhat pleasing, you as a user have to help!

1. You must tell which of the 4 voices are supposed to be matched to the three vectrex voices

2. You must tell which of the instruments(samples) of the MOD are mapped to what PSG settings [The vectrex mod-routines use the BIOS sound playing routines]

(This might not be an easy task, since there are two stumbling blocks:

1. Mod writers often do not name their instruments very descriptive

2. You have to know how the vectrex sound routines work in order to find settings for "instruments")
