I'm working on a sample based autogenerative patch. However I've been wracking my brains as to how to make files in sflist or sfplay crossfade into the next track that plays straight after so as to create a seamless transition.

I've been experimenting with a couple of approaches so far 1) to extract the file length of playing and instruct another sf play to start playing with a ramp when at a certain point towards the end of the file (perhaps through scale? Or division to get a percentage variable?) or 2) to delay the output audio and use the bang when finished.

I'm on the bus now so I can't upload the patch ATM but I can do if it's be helpful to see. I just thought I'd ask in the event that one of you nice folks would know straight away.

Thank you for any help you might be able to share

I think those should help. Also look at the matrix object.

Thanks Richard for the reply, those links are certainly helpful, however the part I'm struggling with is less to do with the crossfade itself but more to do with initiating the playback of track (b) slightly before the end of track (a) and then do a xfade relative to the file length if that makes sense, thanks again though much appreciated!

Try this: When you start playing a file in sfplay~, at that same moment fade its volume to 1 and also use sfinfo~ to get the soundfile's duration, subtract your desired fadeout time (e.g. 2000 ms) from the total duration of the soundfile, wait that amount of time (with a delay object) then bang a message to matrix~ to fade it out and also to start the next soundfile (with a fadein, etc.).

Christopher Dobrian, you are an absolute legend thank you SO much; I can't tell you how much I appreciate it! :)
