A great, simple app
I find this app to be a really useful tool when transcribing. It includes loads of different rhythms, rests and tuplets, and you can change tempo and time signatures. Its dead simple to use - just insert the rhythm like a calculator. I sometimes find that the screen showing the rhythms doesnt show enough of the entered rhythm, but you can scroll along as the rhythm plays. Some of the beams of the rhythms connect together in an awkward or incorrect way. Anyways, this a great app - and its free!
