hi ludi!
try passing nrev not ‘nrev (because scheme uses variables to hold
functions...)
for example this works for me in a lisp buffer :
(load "nrev.scm")
(load "v.scm")
(with-sound (:statistics #t :scaled-to 0.95
:output "test.aiff" :reverb nrev)
(fm-violin 0 1 440 .1 :reverb-amount 0.1))
On fomus, when I built the app I wasnt sure if it legal for me to link to it on
the app store (im checking…)
regardless you can build the system from sources very easily and include fomus
there without any problem, i know it works because thats what I used to teach
last semesters
hope all is well with you!
