Sample with timeindex - Capytalk in timeindex

Question

I'm curious why the sample with timeindex requires a timeindex/pasted sound in the timeindex whereas a samplecloud, tau/psi player etc. all allow you to use capytalk direct in the timeindex field, e.g. (!PenX *2 -1)? This makes scrubbing a sample more convoluted. Am I missing something obvious? Edit: just to add, I know you can use start and end (plus the loop) to do the same thing in the timeindex prototype. Just seems to be a more complicated way...

Answer 1

SampleWithTimeIndex takes an audio rate time index in order to prevent audible quantization steps in the reading of the samples. As a side benefit, it's also interesting to use Sounds other than a straight linear time index ramp for indexing into the sample.

In other Sounds, the timeIndex controls the index at the beginning of a grain or a frame (not on a sample by sample basis) so it is not critical to update the index at the audio sample rate.

Thanks! That makes more sense...

Answer 2

You could also put your expression  (!PenX *2 -1) into a CapytalkToSound and paste that into the TimeIndex parameter. Although you'll probably want to smooth it.
