@Thrifleganger, I’ve been testing the plugins here and Reaper will only show the number of channels defined in the .csd file. AudioMulch seems to, more often than not, show the maximum number of available channels, i.e, 64. There must be something odd in how AudioMulch is reading the number of channels. The strange thing is it that is labels the valid inputs/outputs with parentheses. But it is annoying. In saying that, I’m not really sure how best to fix it. I would rather produce a single plugin that is capable of any channel config than several that are fixed configs.
