Hi Jon,
No problem, I will move this thread to the Boutique for you - thanks!
Aaah, indents always get wiped with the boards unless you paste into a 'code' (the button in the edit screen with a big C in it). I have become really fast at re-indenting code manually, so I will do it for your code too.
Regards, Nic.

Thanks Nic! Oddly I did use the C block but still lost the indents. I'll pay closer attention next time to see if there's anything else I might have missed.

additional background/detail: Michael Brecker pioneered this technique for using monophonic (one-note-at-a-time) input from an EWI breath controller to drive an alternating sequence of chords, producing an effect somewhat similar to a harmonizer, but with some potentially dissonant variation mixed in. Not random, but often unexpected. Here's an early example: www.youtube.com/watch?v=8dxlYxs-qHYMichael used an Oberheim Xpander to do this. Here's an article explaining how it worked: robbykilgore.com/?p=19&fbclid=IwAR3mg2KysrqikZT4t5F1fjrBhXSu-ZoFjDpFEQaYsBqDYTD8TAGadu9ISJIThere are a few ways that a similar rotator effect can be accomplished on an iPad, including at least one app that was designed specifically for that purpose, but I've had trouble getting that one to work reliably for me. With StreamByter, now I have a rotator that loads/saves cohesively as part of an AUM scene, and I can freely tweak the script to add more layers or make other adjustments to how the rotation works. |
