Bueno pues hoy buscando Sintes Free por casualidad me he encontrado con este beat slicer el h4xx0r, se pueden trocear wavs claro esta, y ajustarlos como queramos. Aqui dejo la dirección, descripción y la imagen por si le sirve a alguien.

Introduction
H4xxor is a simple beatslicer featuring twelve user-definable slice regions, each mapped to a midi note. A sample is loaded, optionally stretched to fit host tempo, slices defined, and then played back via midi notes.
Each slice has its own start, end, loop, pitch and amplitude envelope settings, and can be routed to one of four stereo outputs. All slice parameters can be automated in realtime.
Caveats
H4xxor tends to create cpu spikes when slice points are animated quickly while the waveform view is on. These spikes are not reported by the host, however (tested in FLS 5&6, ArtTeknika Console, Savihost, VstHost), only by windows.
To avoid any undue problems, switch the waveform view off if you are automating slicepoints with the gui visible
