Hello, I'm just getting back in to max after a few years away and I could do with some help.

I'm trying to create a patch that will conduct pitch analysis on a sound source, and then alter the playback speed of a ~groove object until the output from that matches the pitch of the first sound source. I feel like the answer lies in sel, > and < objects, but I can't seem to work out the right way to use them. Help would be much appreciated!

Interesting. Your first step might be to sketch how you would do it with an old-style tape machine. You will also have to decide if you do analysis on the tape as well, of if the pitch on the tape is constant. To convert from pitch difference to playback speed, have a look at the [transratio] abstraction (see [gizmo~]'s Help File for instance).
