I use this app with a MIDI keyboard, and it makes a lovely, easily transported setup for jamming with friends. The B3 sound is decent. I think the rotary speaker effect sounds way too fast on the fast setting. I wish this was user adjustable. I also wish I could dial back the vibrato/chorus effect. But this definitely beats hauling 400 lbs of Hammond and Leslie around.

I am having a very hard time loading the presets that a bought. Can anyone help. I’m missing something. For one the app doesn’t have a u1 or U2 bank only 1 to 6. And how do I Play or install the patch names like Jerusalem? yes I already purchased it. Yes this is flustrating.

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!

This app is a must have for any Black Church Organist. Jazz keys player.

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- BJMc Chicago-

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!

I need the app work even when I'm outside of the app.

It's unbelievable what you can do on an IPad Air 2 with apps like these, who needs a recording studio or producer breathing down your neck, recording studios are quickly becoming a thing of the past... Jeff Mercer Mentor Ohio

There is a problem with some of the keys when playing two consecutive notes on a run that are exactly the same note. I have purchased extra sounds on this app but is useless if it is broken. Please fix this problem. Thank You

Yeah I love the app but the Leslie is what needs work the lower rotor is SERIOUSLY Wayyyy too fast,love the wind down time of it but when It reaches full speed it's just too fast,otherwise great app.Leslie lower rotor Doppler effect just need to be slowed down.
