Hi there all. Here are some DSP chains for Renoise using the native FX.
Load these onto the desired channel, and use the Hydra Input slider to set the desired effect - gain will be compensated (as best as I could get it).
These are a guide only. Please do not take these as absolute solutions - you will need to fine tune DSP settings depending on your input sound and the purpose of effecting. For example with the Exciter, you could disengage certain bands in the Hydra and readjust the ranges accordingly depending on your area of focus.
Hope some people find these, at least in concept, useful.
