Help with adding the rest of the JSFX waveforms?

[DavidsonAudioMulti]

I have been trying to add the rest of the wave forms from Tales JSFX. I have been able to get a couple of them but as the formulas get more complex I am having less luck. It seems one little mistake makes for bad aliasing. Is there anyway you could help me include the rest of the wave forms. I would be willing to help do this but I am not real familiar with JSFX. Any help would be appreciated thank you! Davidson
