Also, I don't have to adjust Pd's audio settings. I can use the standard settings (44100, 64 blocksize, 25 msec) and I don't get audio pops, which is good.

But there is one thing that I realised: The wav-files are not played at original speed. They are all recorded in 122 bpm. When I play them with Giulois patch, the samples are played quite slowly, at around 111 bpm.
