Examples

# A 2-second drum groove (4/4 measure)
# hi-hat on 16th notes
hh <- sequence(hiHat,time=2*(0:15)/16,volume=rep(c(1,rep(0.5,3)),4))
# bass kick on 1 and 3
k <- sequence(kick,time=2*c(0,8)/16)
# snare on 2 and 4
s <- sequence(snare,time=2*c(4,12)/16)
# Mix the 3 tracks
m1 <- mix(list(hh,k,s))
if (FALSE) {
# All calls to function 'tuneR::play' ar wrapped in \dontrun{} since they rely
# on an external audio player to play the audio sample.
# See ?tuneR::setWavPlayer for setting a default player.
tuneR::play(m1)}
# Try with less hihat, more kick
m2 <- mix(list(hh,k,s),volume=c(0.3,1,0.8))
if (FALSE) tuneR::play(m2)
