one thing i always use a lot in my pd patches is called a 'wetfilter'. basically it is a bunch of bandpass filters, followed by delaylines of increasing length. kind of oldschool 'spectral delay'.
so, i'd love to have this effect in a small hardware box, so i can put some drum machines and synths through it easily.
what options are available for putting pd patches into small devices with audio in and out?
and, slightly off topic for the pd list, is there already some type of generic 'stomp box' that can load C++ code or something to make effects?
