[PD-dev] interpolating scalar dsp fuctions

[Tim Blechmann]

hi all ...

at the moment the scalar dsp fuctions are working on one float ... if
this float changes it will most likely produce an audible click:

     |float 1(
|    | 
|*~ 0|
|

the usual way to avoid that in pd is to use a line~ object, that both
uses cpu power itself and adds overhead since it's a vector/vector
operation, not a vector/scalar operation any more ...

it would be possible to implement an interpolation between the two
scalars (for one dsp block or so) and thus smooth the transition from
one float argument to another ...

on the one hand this would add some overhead (the check if the scalar
has been changed), but it would be possible to replace line~ objects
with line objects that don't have the dsp overhead ...

i'm curious, what other people think of this ... i could change the
behaviour of the pd interal object or write an external for that ...

cheers ... tim
