Stops working sporadically for no apparent reason. Some solo instruments do not work. Buggy and needs work.

I don’t understand the old neg reviews. I tried the “Free” app on M1 iPad and using two midi keyboards. This app saved me $2,500 (unless I want to go pro) as it is very similar to some of the Ketron SD modules. I can layer in my other midi sounds hosted in AUM and have a much richer sound. I would pay for other features and I am disappointed only in that there is no option. The xMure app does integrate OMB and does offer more upgrade options. There still is enough for a novice to have fun. Helps you work on your timing. Blown away.

Well thought out

Its not perfect, but it is well thought out. You don’t need to leave the app as you have both the styles and instrument sounds within the same app.

I would like to see capability for playing user styles (.sty), but I don’t think that makes sense for OMBs business model, so I am not holding my breath.

To make this a performance tool, please consider some type of midi sync, eg Ableton Link. Also for future updates please consider adding the ability to play Audio Units withing the app.

This is a good start however.
