Sample start, loop start, loop end (and ‘phase’) on a sample oscilator
Would it be possible to get some clarification on how these exactly work?
I’m thinking about how possible it would be to do some slightly more ‘interesting granular’ stuff with Obsidean by modulating these values (kind of like what’s possible in a synth like Mood by Amazing Noises).
So, seems like ‘sample start’ is calculated as a percentage of the total sample duration with the default being 0% - ie ‘start from 0% into the sample duration’.
How is ‘loop start’ calculated then? Same as sample start?
And how about loop end? Same again?
And what happens if ‘loop end’ becomes a smaller value that loop start? (Does it play backwards?)
And finally, what’s a easy way of running a looping playhead along a sample? Eg 10th of a second of smaller duration continually looping, but you move the loop start and loop end points together slowly through the sample. (I’m wondering if perhaps moving the ‘phase’ parameter might do the trick here?).
I’m away from the iPad right now so can’t dig in but I was wondering if anyone actually knew exactly how these parameters worked on the sample oscilator?
Any help appreciated.
