Have a look inside the [waveform~] helpfile. You could also use [multislider] and [poke~] or [peek~] to write this information to a [buffer~] and play it back with [cycle~], [wave~], [groove~] or [play~] depending on what extra functionality you might need.

yes same method very easy. but there would not be much point? use multislider or waveform (that’s what i do anyway).
there are plenty examples in your examples folder / other hiding max folders / on forums
