Advanced Paula Features
Paula was mainly used to play samples and IIRC very occasionally wavetables.
However, it was capable of more than just sample playback. It should also be capable of AM and FM synthesis. There is an order you can set the channels to modulate each other with modulation being AM, FM or both. The FM modulation is 14 bit but being read as a pair of bytes means it'll only run up to 14KHz. The AM modulation is the same but it's only 6 bit out of the 16 bits read. You can chain the 4 channels together so it should be able to do something like 4 operator FM synthesis (or AM or AM/FM). Did any Amiga software ever do this? |

Technically it would be Period Modulation, not Frequency Modulation. It's an important difference because the period value is inversely proportional. What people usually think of with FM, i.e. Yamaha OPL etc. is also a different mechanism again, Phase Modulation. This is a numerically (and computationally) better behaved approach.
The Period Modulation is not especially useful musically but you could presumably get some interesting clangs out of it |
