Can we add more time signatures please?

for 1/5 subdivisions, you can take a stretch of music and stretch it by any fraction x/5 to get into a 1/5 grid
for piano pedals, just get better, you can make artificial pedals if you try, you can even make the sounds of pressing the pedals if you so desire
for the additional octave, go into the advanced settings and detune your instrument up an octave
