Sorry, I don’t know of any videos…
I typed this out already though so here it is…
When you have a nice group of machines/samples/settings it’s often worthy to have a few patterns of variations or a progression of sequences that builds. The second pattern can have a different bass line but using the same voice, a different slice remix of a sample with a different order of slices and maybe some pitch locks and fx locks added, maybe you had a thru track going but you want to add a some sequenced fx and stuff to it, maybe you want your vocal sample to reverse, maybe add more hits to your drum tracks, maybe add some trigs to kick in a recorder and some to play the sample warped and sequenced. You make more changes to the third pattern, all on pattern level using trigs and locks, sample locks even.
By using the same part for these you get a nice progression and it allows you to mix(maybe your thru track was too quiet and you turned it up on pattern one, you don’t want it to jump back down on pattern2), add fx, change whatever settings you want like reverse the slices and filter the drums, and all your changes carry through the progression. When your progression is done after maybe two or five patterns or whatever and your tune is ready for more drastic changes, begin to use the next part for the next several patterns in a bank…
Even just the mixing part, having track volume changes remain when switching patterns, is crucial for live performance where you can’t stop, change the other patterns settings, and re-record… Same part for several patterns also gives you freedom to choose scenes on the fly, and not have them all switching up on pattern changes… Haha, I keep thinking of stuff, I guess I’ll stop now…
