[PD] note data record / playback

[David Powers]

Try using two arrays, one for the data, one for a timestamp. The two
pieces of data would be associated based on a common array index. Then
you can use the [textfile] object to store the data, in a form like
"$data $timestamp;" on each line. Thus, each line of the textfile
corresponds to an index of the array. There are some timer objects in
PD to get a timestamp - you may or may not want to quantize this. If
you wish to capture note events, you may need a more complicated
scheme, such as: array 1: velocity, array 2: note#, array 3:
timestamp.

In this scheme, you are limited in the number of total events, but not
in the length of time a loop can be.

Note that PD doesn't know where a "1" is, so you will have to develop
a custom timing scheme to represent loops and metred time. The
standard 96 ppq timing is fairly simple to implement, depending on
what resolution you need.
