Hi all of you,I'm goldmember since 2 years but still a very newbie
in fact I totally am hermetic to all that can be mathematic and programming
in Usine it takes a great place to realise patches I open existing patches
to see how they are build I read the manual even in french I don't understand
the action of multipliers,dividers,0to1,A=B etc.....
Since 2 nights I attempt to build a patch which would shuttle back and forth between
the end and the beginning of a sample ( when the sample reaches the end it plays backward
as if I pressed the "reverse" switch and when it reaches the beginning it plays forward and like
this infinitely) and as we can set exactly the length into the sample it may be interesting
So is there anybody who can show me how to realise this patch ?
it will help me to understand how to use modules
thank you for your answers
sincerely

with sampler set to button playng mode.
so when u press play the sample start playing, when the sample stop playing, (so when playing goes "from 1 to 0" it send a pulse to restart automatically, and toggle (alternates 0 then 1 then 0 ect) the reverse fonction at each loop end.

just one detail , 23fx use the new sampler of the beta version...
so you don't have the outlet "is playing"
but 'it's not a problem , cause you can do the same patch , just use the "stop play " in the place of the "is playing "

hi, thank you for your answers and forgive me for the lateness of mine
it works very fine !
I already tried with the toggle module and the 0to1 but I placed them
on the line of the endpos or startpos and thus the toggle module was always
exited then it didn't reverse and the sampler was on loop
thank you once again
but if it does not derange I'll be back on this post to have explanation
for the use of other modules (where to put and what can I connect )
good evening and have a nice night too
