Reviews

Great But-
Lmxeric

Everything is awesome and has nice and easy setup. The only problem I have is that occasionally it just won't register me tapping the keys or anything on the screen besides the ads, the only that signifies the app isn't loading or frozen. I've closed and reopened the app and also rebooted my phone but the best solution I've found is to delete and reinstall the app. Again great app, just a small bug that's causing a minor inconvenience

Trial can't be tested

So... I cannot actually TEST the connection to my other synths to use this as a controller? As a synth, it is average to decent. Not as good or as detailed as the free Yamaha synth, but still useful.
