I like thus app and have had fun with it. I agree with others that theres room for improvement here. - the fact that the sound shuts off as the screen goes to sleep should be fixed. - Id like to be able to save groups of beats. Its nice to have up to six sets here, but Id like to save stuff I like, so I can move on to other beats w/o erasing the "keepers." - finally, allow for the settings like "snappy" and "hi/low" to be applied differently to each beat. That would be helpful. Also, it would be nice to adjust the tempo by tapping as a short-cut, as well as incremental "up/down" adjustments. Really cool app. Thanks for the hard work. I look forward to updates.
