Why can i only play i set of notes in live?

im not sure if im sayin this the right way but, when i put two or three sets of notes on the piano roll and play it back, i only hear one line of notes, and its usually the 1st notes i put in? does anyone now how to fix it in ableton? or even know what im talking about?

is the sound your playing from a monophonic synth patch?

emm, i don’t understand? i usually use Z3ta or sylenth and try to make a progressive house sound but no matter how many notes i put in, i still get a really hollow sound of one note playing… like a C3 for example just on its own

If you are using Sylenth, you need to put the number of voices up higher. I have never used Z3ta. Its PC only…
