Meet Galileo Organ 2: the next generation in tonewheel and transistor organ modeling! Benefiting from completely redesigned physical modeling techniques, offered as a UNIVERSAL app with a built-in AUv3 plugin, and presenting many new parameters, Galileo Organ 2 is the culmination of our adventure into recreating that perfect analog organ sound.

With 17 different organ types, three individually configurable manuals, scanner vibrato/chorus emulation, newly designed rotary cabinet & tube amp sims, as well as many new fully-stereo professional FX, Galileo Organ 2 is able to achieve sounds more authentic and diverse than ever before!

Designed for the professional, Galileo Organ 2 offers extensive MIDI support, full connectivity via AUv3, IAA and Audiobus, over 300 presets in many different genres, as well as the ability to import original Galileo Organ presets. The best organ on iOS just got way, way better!

What’s New

Version 1.1

This app has been updated by Apple to use the latest Apple signing certificate.

• Added two new parameters for further percussion customization. Located in EXPERT -> Page 2, the UP CV BYPASS and LO CV BYPASS toggles now let percussion signal from the respective manuals bypass the organ Chorus/Vibrato (bypass is off by default), so as to get a Jimmy Smith-like effect.

• Addressed the issue where MIDI Sustain (CC 64) wasn’t mappable to parameters. (Don’t forget to enable Sustain filters by going to EXPERT -> MIDI if using the sustain pedal for things other than note sustain…also remember that you should select the "momentary" option under a Galileo 2 parameter's MIDI learn prefs, if that parameter is binary (you know, a switch...) and you're using something like a sustain pedal to toggle it (sustain pedals are "momentary").)

• Addressed the issue where external MIDI In on/off settings (found in PREFS -> ADVANCED MIDI) weren’t persistent in AUv3 version. Now they are remembered in the state of each separate plugin instance. ALSO (this is important), the external MIDI IN will now be OFF by default when using Galileo 2 as an AUv3. If your DAW or host doesn’t throughput external MIDI into plugins, then you should probably turn these switches on to use a MIDI keyboard, etc. For example, if you're an AUM user, you want the physical MIDI In to be on for external keyboards to work, but in a DAW you'd typically have it turned off, etc.

Really nice, but..

Great sounds but some controls too fussy. Also, I find I’m always turning down the default reverb level on pretty much all the presets I might use. The tuning control combines both transpose and fine tuning in one control to the detriment of both. Make them separate for goodness sake. On iPad I find it very difficult to return a rotary knob back to its zero because the readout is under my finger. This could be fixed. Hoping to find its all pilot error.

Great organ sound, but restarts every time I switch to app from another app...very annoying

Fix that bug and it’s the best out there

Just amazing

What this gives you in a tiny package is more than seems should be possible. It gives you a church worthy B3 or a leaky, clicky, mess with big vibrato. Or a Vox. This is a brutal 1-2 punch of quality sound and portability that is amazing. With the right controllers, it sings. Very easy to program MIDI controls. Very very satisfied with this app.
