For this you might really want to investigate Jesse Chappel's 
SooperLooper application. It's an emulation of the Oberheim digital 
Echoplex, and does great work for looping, overdubbing, loop 
quantization and all kinds of other tricks.

You are welcome to test drive my Looper abstraction, which is attached. 
It's an upcoming release, and allows you to capture a loop and play it 
back or granulate it. It doesn't do overdubs, which is what I gather you 
are after. But maybe some of the mechanics would be interesting for you.

Abstractions:

1) looper.pd
2) loopreader.pd
3) random_range.pd

Looper usage: [looper /uniquename keyname1 keyname2]

keyname1 = key to toggle looper on/off
keyname2 = key to toggle grainer on/off

I usually use it with [hid] and a footswitch, but it takes simply 0/127 
to trigger recording. Have fun!
