Thanks! I realized I could've just adjusted it all on the centroid. It may not be perfect, but I think that's just because I have it all jammed on the one lol.
i mean.... this didn't really help, but i like your spirit. I would turn on keyboard tracking (little kb label down under the filter) so that low notes are more cutoff and closer to sine waves. I would also tighten up the decay, sustain, and release of the whole instrument.
