Hello,
A few weeks ago I was reminded of my promise to share [soundtouch~], a SoundTouch port for Pure Data. I use this class since quite some time now, and had the code available on my website earlier on, but when I found that it could not work for Linux 64 bit I withdrew the project for a while. Reportedly, Olli Parviainen's newest version of SoundTouch is ready for 64 bit. I can not check this as I have no access to a 64 bit machine at the moment.
