There is something verry weird about the filter freqency range .
Most noticeable on a init patch .
Set all filter parameters to init values and set key follow to zero , add some resonance
THe filter frequency between value 0.2 and 0.5 hardly moves.
When applying a decaying envelopev to the filter freq (filter freq. to zero , and filter mod to full ) , the reponse just feels verry weird when this region is reached with the envelope .
No matter the curve of the envelope .
