hello all, -this is cross posted @ kineme forums, apologies, but i don't know the overlap between that community and this mailer. -
i am trying to using midi data to smoothly rotate a image on a billboard in a loop once every x bars. qc is receiving midi data via iac bus from ableton. using a linear cc curve which climbs from 0-1 (x360) over the length of the bar (s) should do it, but when i watch this number as a string i see the frequency at which qc is reading this number is not high enough to capture the rotation at full resolution, therefore the image moves in choppy fashion. this same lack of sufficient resolution results in qc being unable to make a stable calculation of bpm using the two bpm calculator patches others have built. so i can't use the midi clock receiver and/or either of those bpm calculators to generate a non-choppy interpolation 0 - 360 using the interpolation patch with external timebase or other calculation techniques I'm familiar with. is there any other way to do this? some other calculation method? some way to stabilize the calculation of bmp? anything? for all other modulations this lack of smoothness is not an issue for me, but i really need interpolation to be smooth for continuous rotation. anyone? thanks a bunch r.
