Maybe using tabplay~ and soufiler would work best ? Would tabread~ be better ?

I think one advantage of using tables is the fact that one could start playing anywhere in the sound file. It is not the case with reasf~, right ? (might not interest Patrick, but it is interesting for me)

Then, using tabread4~ would consume too much CPU, right ?

So, dynamic table + tabread creation with throws would be the way to go.

Do you guys know a way to clear only several objects of a subpatch ? I use [; pd-subpatch clear< for now. But I would prefer not to clear everything.

i guess the simplest thing would be to use [readsf~] for playback of the
samples from a ramdisk: this way the samples will still be kept at 16bit
(or whatever you choose) and thus take little memory and the access to
the ramdisk will be lightning fast.
