This app sucks, it crashes constantly after connecting or playing mp3s; you have to jump through hoops to get it to work properly. You can modify the presets for your keyboard but (at least for my keyboard) it only has three effects to change (minus EQ and volume) and they don't save when you disconnect from the app. Huge disappointment and I'm probably just going to sell my Williams and buy a better keyboard

Bluetooth does not work. Following the instructions, I get as far as the popup/text box telling me I've connected to my keyboard, only for it to stop there. The popup/textbox claims I'd be taken back to the homescreen when connected but it never does. If I leave the popup/textbox, the app tells me I still need to connect to my keyboard, indicating it never connected in the first place.

This app is completely useless? The only kind of useable tools at your disposal are the metronome (doesnt change metronome on your piano), reverb settings, adjustable split function, and slightly more variety on piano sound settings (doesnt even allow for custom ones). Despite the sticker on my Legato III informing me that I can record my preformances, that function is nowhere to be found on its barren and buggy app.
