#ambi_glass workout by Robin Newman, July 2016
#features retriggering samples before they end in live loops, killing the previous sample by setting its amp: to 0
#three live loops, one using ambi+glass+rub, a second featiuring tomtoms and the third using loop_amen
#a fourth live_loop (:audio) allows fade in and fade out using an fx_level control, and kills the other live loops at the end
# you can alter the numbers in the audio loop to control the duration
