Sure - that's a fair comment and a design decision once some project
like this gets started. I just brainstorming. However, even with an
onboard DSP, which is most likely what Pro Tools does, we'd still need
to map from LADSPA C code to DSP code. Is that easy? I don't know.
Luckily I think we have many people here who probably could do good
stuff if they thought it was important to do.
Thanks for your input.
