[PD] block~ vs. freeverb~

[Derek Holzer]

Try sending very large values to "roomsize", which would make longer 
reverb tails, and very small or 0 value to "damping", which increases 
decay time. My guess is that [freeverb~] calculates the decay time in 
samples somehow, thus the very short reverb times at very fast sampling 
rates. Alternately, move [freeverb~] out of the upsampled subptach, it's 
probably eating tons of CPU by being there anyways. Try to concentrate 
only the objects which might produce aliasing in you upsampled 
section... oscillators, pretty much, although I don't know exactly what 
you are doing with waveshaping so I can't tell if that could produce 
aliasing as well. But anything else getting upsampled besides the 
potentially aliasing objects and the filters used to anti-alias them is 
really a huge waste of CPU.

best!
