Hey - you asked for the same thing in another post (https://cycling74.com/forums/sampler-patch-to-sample-and-manipulate-a-few-audio-files-pitch-speedetc).

Check out [groove~], using [waveform~] for selecting the area which you want to play back.

The rest is just a lot of [slider], [led], [umenu], a [meter~], a [pictslider], and some number boxes and toggles.

As for the underlying structure of the patch - it does what you see, just connect each number box/slider/umenu/led to a particular attribute/inlet of the [groove~] object.

I guess what the [sequencer] does is that it splits the file into the amount of sliders, and each slider is the volume.

Also check the MaxMSP extras which come with the application, you'll find a lot of that kind of stuff there (granulators, sequencers, scrubbers etc).

If you really desperately want to get your hands on the patch - why not send a message to the youtube member who uploaded it? :

Although I always advice someone to challenge himself, here's something I did a while ago, close to what you ask for. For multiple audio files playing simultaneously, just copy/paste what you need and go crazy.

And please, don't spam!

Take care, Yiannis
