Hi I recently bought MM15 and it doesnt work properly. When I use the soundpool and I create the song it is fine and then when I go to play the song. If I use 3 instruments, only two will play properly and then the rest name a grrrrrrrrrrrrrrrrrrrr noise. Help!
I guess it is due to your computer which is perhaps not fast enough or your sound card is not relevant. What hardware have you (CP, RAM, sound card/chipset, XP, Vista, Seven)?
Try to export your song in a Wav file and listen to it with WMP by example, normaly you will not get "grrrrrr......" noise. If you don't get it, this confirm the first hypothesis.
