Superb Programming

Guido’s brilliant programming has truly captured the essence of the unique and rich sound of the Hammond tonewheel organ/ Leslie tube type rotary speaker. I used the original VB3 on my laptop for live performances on a regular basis, for years. He has since brought this remarkable sounding Hammond/Leslie combo to the IOS platform. Taking VB3m to the next level, Guido has now given us the option, for a very modest price, to add the very same Leslie emulator, to our IOS devices, as is included in the newest laptop version of VB3 ver 2. This new Leslie emulator gives you greater control over its entire operation. He has accomplished all of this in an extremely tiny footprint. Purchasing VB3m and Rotary speaker is a must have combo for all keyboard players! Thanks, Guido for your remarkable programming abilities

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!

Thank you for your work on this app!! I have had many Hammond organs and Leslie’s in my day and this satisfies me completely! The percussion is awesome. I haven’t yet tried double manuals and a volume pedal yet but that’s next. The Leslie effect is wonderful as well. If you love the Hammond experience don’t hesitate to get this! I can’t recommend this enough! It’s great to see someone who really cares deliver such a wonderful musical tool. Thank you Guido!
