Re: Lance's 50khz playroutine

Hi !

There is always room for improvement.
It depends on the goals you seek.
I can beat myself with ease using for example around 2MB of memory for generated code.
But who then would use a routine to play a mod, that should be only a small part of the demo, if half of the maximum atari ste memory is used to do that ...
That is why i leave memory hungry stuff optional and i skip completly the super hungry memory possible upgrades.
The same applies for cheating. The goal remains to have good quality sound and so any cheat is left as an option.

Ok, but here is a new and not planned version 12 now ... :)

As i found and corrected a bug of the original Lance code with Note Delay effect (EDx) that has an audible impact in the famous Kefrens Desert Dream 2 mod around 3:35 minutes and i add an idea about a progressive cheat option, i decided to do this build before the possible BPM build.
You can try the file desertd4.mod with the old code or the original Lance code and compare with the result you get now, you get with Octalyser (that does not use Lance feeder), or with the one you get with Winamp or Milky Tracker.
The "read skips" cheat, as i called it, is like a progressive octave 3 cheat.
It allows you to specify a number between 0 an 13.
Value 0 means the cheat is not active.
Any other value, means the cheat is active and it disables the "octave 3 cheat".
Any value will not affect the 12.5 KHz replay.
Only values above 7 affect the 25 KHz replay.
All non zero values affect the 50 KHz replay.
Low values will only affect the top octave 3 notes. A value 13 will have a similar impact to the octave 3 cheat but in a different way.
Low values mean less CPU saving and low sound impact. High values mean more CPU saving and more sound impact.


Enjoy and have fun,
Paulo.
