Doesn't work, no sound – 8Bitone+ MICRO COMPOSER Review

I wanted to give it zero stars but that isn't possible. There is no sound when I use this app. No sound means that it is a 4 dollar ripoff, I feel like an idiot for buying this app. I plan on emailing the developers about this. There is an outside chance that this is just a fluke and I am making a mistake but i don't imagine that is the case. People shouldn't sell things that don't work, I hope this warns potential customers, and I hope this issue is resolved I was excited at the prospect of having a sequencer like this on my phone but was let down.
