Hi Dash. Thanks for your question. The problem we've been facing is that JUCE, the audio library that DecentSampler is based on, doesn't support dynamically adding and removing automation parameters. This is a problem because each sample library is necessarily going to have different parameters. I'm thinking the appropriate approach might be to sort of "pre-declare" a certain number of parameters that will then be mapped onto whatever controls show up for a specific sample instrument. In other words, it's on the roadmap.
