I’ve been searching and searching and can’t manage to get this to work. I have a buffer with three audio files in it. If one is playing one of the others gets a bang, the one playing needs to crossfade with the new one. I have attempted to use the line~ object but to no avail. Any help is greatly appreciated. Patch is posted below.

thanks,
Dan

you don’t have one buffer, you have one polybuffer which contains several buffers
you should have three different play~ objects if you want to read three sounds at the same time
something like that could work if you have short samples

you should definitely check out the help file of polybuffer under the tab “sampler”
and the help of poly~
best

Is that what the [change] object is used to ?

Is that what you mean ? Maybe a solution could be to delay the bang accroding to each sample duration ?

one possible way to deal with that would be to keep track of the previous “player” played
something like that might work

I tried and it seems to work
