i am trying to create a loop with is always 4096 samps long regardless of the file size referenced. using loop end in the the sample sound object.

i am at (!start + ('filename' sampleFileDuration s samp - ('filename' sampleFileDuration s samp - 4096 samp)))

i don't have a lot of experience yet going back and forth between samps, time and in this case a 0-1 range.

i think the next step is to covert back to a 0-1 range number. which i think works to:

(!start + ('filename' sampleFileDuration s samp * (('filename' sampleFileDuration s samp - ('filename' sampleFileDuration s samp - 4096 samp)) inverse) removeunits))

next:

!Start + (4096 samp / 'aSampleFile' samplesFileDuration samp)

This will keep the EndLoop 4096 samples ahead of the StartLoop (except when !Start is closer than 4096 samples from the end of the sample).

As for the Frequency, the Frequency field is independent of the loop length, but if your intention is to use the Sample as an Oscillator on a wavetable 4096 samples long, you could use:

default hz * !Pitch hz / 4096 samp s hz

The reasoning is that "default hz" will play 4096 samples in 4096 samples of time (or "4096 samp s hz", roughly 10 hz at 44.1 khz sample rate), so you need to scale the default frequency by the ratio of how much larger the desired pitch is above the default pitch.
