Just got a Casio PX-760, which only includes a handful of built-in instruments. This app was a simple way to test the MIDI interface and play with a bunch of different sounds. I finally found something nifty to do with my USB OTG adapter.
My digital grand piano isn't getting detected. It's a Yamaha clavinova by the way
It doesnt work after downloading the soundfont it keeps warning there is no soundfont. How trigger sounds? Only midi cable? No screen keyboard?
Very simple and to the point, and it works. Load up a soundfont and play with low latency using the excellent FluidSynth engine. Beautifully native Material design, free and without ads. I could wish for just a tad more features, such as quicker instruments/soundfont switching and perhaps some save/restore functionality for channel setups, but it's still easily five stars in its current bare bones state. Recommend.
Works very well. Provides a General MIDI synth that can be used with a USB keyboard. Also other apps can send it MIDI commands through the new MIDI API in Marshmallow. So you can use this synth with lots of other apps. Android needed this app!
