# Avoid using sample_duration to set the sleep time in live_loops
# It is possible to use sample_duration to drive the frequency of a live loop.
# However, if you're using a rhythmical sample such as a drum beat and it isn't
# in the same BPM as the current BPM, then the FX such as this slicer will be
# badly out of sync. This is because the slicer slices at the current BPM and
# this live_loop is looping at a different BPM (that of the sample)
# Instead prefer to set the BPM of the live_loop to match the sample. It has
# two benefits. Now our sleep is a nice and simple 1 (as it's one beat).
# Also, our slicer now works with the beat and sounds much better.
# Alternatively we can beat_stretch the sample to match the current BPM. This has the
# side effect of changing the rate of the sample (and hence the pitch). However, the
# FX works nicely in time and the sleep time is also a simple 1.
