i know i can easily speed up a sound file's playback by altering the

playback speed in sfplay objects etc. and other software does things

like time stretch/compress with pitch correction. my question: is

there something out there for maxmsp that would enable us to make a

soundfile play progressively faster but doesn't raise the pitch?

again, the first part can be done with a ramp to the speed input on a

groove object, but what about pitch correction?

alternatively, is there other software out there that can do a dynamic

real time speed increase/decrease with pitch kept stable?

Have a look in the Examples/Sampling/granular folder.

For external software you might wanna try SoundHack (free). You can 

draw Graphs for speed or pitch change and then save output to a new 

Or if you really need the real time thing try ableton live - though not

The residency~ external from FFTease can easily do this.

or use standard msp-objects like gizmo~ and feed it with a speed-

doesn't sound too bad.

Here is an example of how to do this with standard MSP objects:

Uses about ~2% CPU on my Powerbook. The idea was to keep it efficient

so I could use 20-30 in parallel.
