Heavy use with varying degrees of success

I use this app to live record into GarageBand, and it comes in handy for making sound effects. However, just recently I opened the app to discover that the instruments suddenly stop working if you turn off both effect filters in the EFX/EQ module. I used to be able to leave the instruments completely dry so that I could hear the raw sound accurately and make precise adjustments. Now, the program disables instruments completely if the effects are turned off, or even if they’re set to “thru.” I even reinstalled the app and encountered the same problem. Pleas fix this rather serious obstacle.

Great fm synth app but with one disappointing limitation

Successfully unlocked this on a MX88BK (in-store) and mostly love the capabilities of this FM sound module/app. Works nicely and can create and save new 4 operator FM patches just fine. The only real limitation is with the LFO. While it is possible to use the LFO on each operator separately, there is no LFO delay parameter like on a real dx100 or tx81z, etc.. This is a serious (and annoying) limitation. The only way to “delay” the LFO is to use each operator’s envelope params by setting a slow attack.
For example, if you want a delayed vibrato (like on a flute or sax patch) this can be accomplished easily if there was a LFO delay parameter(like on a real FM synth). But with this app no can do.
Please fix this Yamaha. I know you won’t because you don’t really care but it’s worth a try to ask.
I guess you get what you pay for. Lol.

Uh, No

First off, the app in its unlocked state is pretty interesting in its own right, particularly if you've owned a DX7 or similar synth. The supplied patches are 'meh', but will whet your appetite.

The kink comes when you try what's described in the above review. The keyboard specialist at the retailer I visited knew all about the app, but pitched it as something that was slaved to a particular keyboard. Yours. You buy an MX## and you can use the supplied cable to interface with your iOS device and unlock the 250+ additional voices. When I asked him if he could unlock it with a display synth he said no, it wouldn't work apart from that keyboard.

Not to say the app's not cool, just that it's a fail as described above. Likewise not to say I wouldn't get an MX88 later and use this - I own and enjoy lots of YamaStuff.
