Re: [sc-users] Help me map a control rate signal with a buffer

Hi Carlo -

One way you can do it is using IndexInBetween to "unmap" your input
into integer slots, and then use IndexL to do the reverse, to "map"
onto your other distribution. This example maps a sort-of-exponential
curve onto a sort-of-sinusoidal curve:

~from = [1, 2, 4, 8, 16];
~to   = [0, 1,  0,  -1,    0];
x={IndexL.kr(~to.as(LocalBuf), IndexInBetween.kr(~from.as(LocalBuf),
MouseX.kr(~from.first,~from.last).poll).poll).poll}.play

Hi! Thanks for reading. I'm looking for some help... I need to
re-shape a control rate signal with a mapping function defined by a
series of float (X|Y) values and linear interpolation in-between.
Using a buffer seems to be the most elegant way to do this, could you
kindly point me to Ugens that might do this? IndexInBetween seemed
promising but then the X-Values have to be integers. Thanks!

 Carlo
