fl is weird with MIDIs. i can never get it to work very well, so you might want to try a different app if that's what you're going for. however, if that's not what you're looking at - then fl is a great choice given its affordability and user-friendliness. perhaps i should just compile a list of music development applications to avoid these threads in the future. :0
A thread hath been made for this general topic including a list of software choices and other links. please re-direct your attention
here. :}
