Thanks for getting the math right Stefan.. :) I was thinking while I was typing, and oviously doing more typing than thinking when I simply doubled the range... lol.. :) peace -cpr Quoting Stefan Tiedje <Stefan-Tiedje@addcom.de>: > cpr@musetrap.com schrieb: > > So, I think, instead of the a new ultimate looper, we need an > > ultimate midi pedal.. which is not a new topic either.. :) a device > > where the knobs, sliders, and/or pedals have the ability to send not > > only standard midi, but the ability to pair up CC's for the improved > > resolution.. of course, since we are moving out of the 'spec', we > > could go as far as combining more than 2 CC's for an even greater > > resolution... > > This isn't moving out of the specs, 14-bit controllers are well defined. > But resolution isn't a problem with foot pedals, I doubt you could > control more than the 128 steps with your foot.
