sounds great, controlling swells like another parameter on preset basis sounds like lot of fun in combination with other parameters controlled by exp pedal

I think this was a key decision, and the main one I was hoping to have implemented.  Among the many other applications across the 'Factor / H9 algorithms, InSwell is one component missing for accurate XP-300 Space Station presets (for example).

I'm curious to see how it all interacts with envelope-controlled effects, or pitch shifts and mix.  We all know how useful this is going to be with delay lines.  But parallel parameter control as a per-preset option is as versatile as it gets.
