I'm not sure they'd give you floating point operations. Another route would be to weld a lowend cpu on the board, but I'd guess that will be expensive and difficult. > It might be more cost effective to use DSPs -- that is: more cost > effective in the long run for everybody -- mostly the end user. Yes, but coding for DSPs is really hard work, and LADSPA plugins wont port over as they use floating point maths. - Steve
