Awesome Organ

Great instrument; But I can't agree more with the other guy's comment...this app would have it nailed if only you could control the Leslie's speed via foot pedal.
I solve this frustrating issue by switching the the app's brake to off, then open it in audiobus along with ToneStack 3 (Yonac). I then play it through 2 of ToneStack's most killer stompboxes: the 'Rotarybox' and the 'Scanner chorus/vibrato'. It makes for a super sweet combination.
NOW... I do want caution those of you who use iRig keys PRO. I have had a weird problem with C3B3 repeating the same register/octave while move up and down the keyboard. It's only happened w/ this app on that controller (???). If I'm missing something, help me out; But I can't figure it out. I'm thinking its the app because when I switch to another app like Garageband I don't have this problem. I only use C3B3 with either my Carbon 49 or Axiom 61.
Anyway I'm sure that's plenty to ponder- that's my 2 cents-

Unequaled tone

I am putting together an original psychedelic rock album and searching for the Steppenwolf keyboard sound. I put this app through an EHX Lester K with the drive cranked on both and get an amazing sound! I hate dealing with the iRig stuff though so I bought a nord Electro 6D figuring the sound should be at least as good as this app for $2.5K - no dice. To say I’m bummed is an understatement. Even into the Lester K the nord doesn’t come close. I’m new to the nord so I’ll see if there is a solution but this app is an amazing recreation of a Hammond organ and dirt cheap!

Great developer

I mentioned to the developer that it would be great to be able to change the midi channels. Boom - done. (Haven't checked if sustain pedal controls Lezlie like w g-band organs, but hoping..)

Now I can keep GarageBand off completely; as its omni-midi interferes with the other instruments while I use Audiobus.

The least I could do was purchase a Joey D soul preset for $.99!
