Great app and.......

When I first heard the VB3 for PC I loved it. And when it was used as the engine for the Mojo I was sold. Kudos to Guido. I like the idea for this app and would like to see a few improvements such as user saved presets, midi learn, a clean setting on the drive knob
( all the way down, there is still a lot of drive at the zero point ), the Leslie speed switch also included on the organ page, maybe more presets too. I’m using my Mojo as midi controller and the drawbars and many of the buttons correspond. I notice my expression pedal only pushes the swell half way up though.
I think this is a great start and worth the price.

Wow. Thanks for the great update!

Great App

Simple, but sounds great, one of the best Hammond sounds available for IPad, very cheap too, the only competition which I also own is the IK, but is a lot more $$$$, but as far as sound they’re a bit different but both great.

No ability to save DB registrations???

I play the real thing regularly, and there is one feature that, IMHO, absolutely needs to be added before this can be a viable live-use instrument: the ability to SAVE drawbar registrations!! When you are working with only a single set of drawbars rather than the real thing’s A/B sets, having the ability to bounce to alternate registrations QUICKLY with presets becomes pretty essential, PARTICULARLY if you are also playing LH bass. Please, please, please, I’m begging, add this feature and let us map those drawbar registrations to MIDI triggers. And I mean just saving DB registrations, the way the reverse color keys work on the real thing, NOT saving whole configurations as in the current user presets.
