Yes I just bought it and it works with the sound canvas app. Another idea to use this is with the app bismark bs-16i. This is a sampler and you can load soundfonts. There is also a xg soundfont set you can download. Just search on google.
BS-16i is certainly a great opp which had its beginning as a VST plug-in, but the Japanese developer discontinued it. Right, there are many soundfonts on the net - even Ketron 2, Ketron S1000, and Ketron SD90 soundfonts some people in Europe sampled. Anyway, I connected my Ketron SD1000 hardware module to my iPad as a sound source for CompanionP. It sounds good, but CompanionP couldn't change chords on every beat. OMB (IOS demo version) was able to do it. Maybe we should write to the author and encourage him to come up with a "pro" version with more features.
