[PD] triggering a linear ramp with a signal

[Micha Thies]

hello frank,

thanks   for  the  answer  which is quite helpful. i already thought about
using  vline~, but didn't had a closer look at it. one reason is that i
wanted  to  avoid  the  message  level  at  any cost, because all this
message  timing  and  pre-microsequencing  makes  granular  synthesis
(and basically almost everything) unnecessary complicated.

and   you're  right, rampsmooth~ is message based, this is why i wrote
some  java external which triggers a defined ramp upon a click, all on
the  signal level, with some extended modes. this made my life so much
easier,  i  can't understand why such a thing isn't implemented in max
or why there is no external doing that kind of stuff.

one  workaround would be, to multiply the ramp generated by rampsmooth
or  any other linear ramp generator and then clip it. the problem with
that is obvious, you can make the ramp only faster and can't retrigger
it for a fixed time.

another    solution    would    involve  some signal accumulator (btw,
what  is it called in pd?) and summing up the delta values. in max the
+=~ is not resettable by a signal, so i went for my own external.

unfortunately  i  am no good c programmer, so i could have now ported
it  easily.  the  code in java is extremely short and i can give it to
you off course.


well,  looking  forward to exchange some ideas tomorrow, would be nice
if you can make it...
