I'm a musician and producer. I'd love to have some apps that do music or recording related stuff. You never know when musical inspiration is gonna hit you. And some nice tools to help that creativity along would be great! Anyone know of any apps that do the following? Make, loop and playback drum beats. Play and record virtual guitar and bass. An app that allows for writing sheet music and playing it back with midi sounds. Or even an app that allows for multi track midi recording and playback for quick on the fly arrangements, and a good way of working out musical ideas. Anyone have any feedback on some stuff like this?
