Pitea

This is by far the best pipe organ app for iPad, iPadPro, iPhone, and Macs. The musical sound quality is superb.

we have a two-manual digital organ now finding second life as a VPO controller. I tried installing the GrandOrgue as well as Hauptwerk, but had various problems. I now have eight of these "little" VPO apps from Markus Sigg, and they are just fantastic. We run them on MacOS and iPad, with various midi-adapters from m-audio and PreSonus. The USB MIDI devices with analog audio-out work best with iPad so you don't have to fiddle with the headphone jack. Be aware that the larger bus-powered adapters will require the "USB 3" version of the iPad camera adapter to provide enough power. The same setup works with the iPhone, but the small screen is better with the "Mini" or harpsichord apps with fewer stops (otherwise they're difficult to tap)

The Pitea pipe organ synth has been very helpful as a way to test MIDI music for real pipe organ, and add voicing to smaller real pipe organ. Pitea is the backup we use for a real church setting with real organ as well. The app works just as well on MacOS, iPadOS, and IOS. It's a wonderful gift to the musical world that's far, far easier to implement and maintain compared to other pipe organ synths, including the most expensive ones.

The sound quality and playabiity of this app are undeniable. This will blow your mind and well worth the cost of admission. If It ever becomes an AU plugin, I'd think every studio/music producer on the planet would want a copy. All of Mr. Sigg's organ apps are impressive, but this one takes the cake IMO.

I have several iOS organs and all I can say is just “wow!” It’s worth the money. I’m a big fan of Crudebyte. A huge fan in fact, but iCathedral can’t compete in my ear. Omenie is great, but their 2 organs don’t compete though they are light on the memory and processor. I truly enjoy all those apps, but this is simply a different league plain and simple. It struck me so much I tried another from this developer, the Esmuc V1, and I am equally blown away even though it’s half the price of this and has less stops. I’m a bit lost for words. If you love pipe organs, you’d be silly not to get one of these. I have a feeling that the others would be enjoyable as well even if they are of a different flavor. You don’t eat the same meal everyday, so why play the same organ?

I write to congratulate the developer for this absolutely stunning instrument. I am a professional organist and organ builder and am totally amazed at the superb results of this application. After reviewing the free version carefully I purchased the complete Pitea organ and am stunned by the result. Thank you Markus for making this wonderful instrument available to us, it’s worth every cent in cost. Adrian Ridgeway ARCM, LRAM, LLCM.

If you are serious about your organ collection and finding inspiration to play organ, then this is it. Burea, Pitea and Jeux are my faves from this committed developer. You need to have at least one of his amazing apps. After trying one of these, you will be hard pressed to find a better product.

These apps are quite impressive - hook up MIDI manuals and pedal and a virtual organ on an iOS device, instant start, and no fuss. Sure, it's not as flexible as Hauptwerk but consider the cost - a great alternative for practice and live performance in venues with no instrument. I have Burea, MarcMoerd, and JDO and I'm glad because they all have their charm. If one could spring for only one of the top tier apps I suggest this one (Pitea) because it offers a variety of tonal palettes including a celeste which while maybe not of high importance to organ reform enthusiasts serves a purpose for those of us raised on American classic instruments.

I've now reviewed all of them that I have. This is a bit more refined sounding to me though that's probably uselessly vague. Not as big as the Burea, more clarity between the different sounds than Jeux.

My fellow organists are astounded and amazed at the quality of sound coming from my iPad. The attention to detail of the producer is clearly evident in this and the other instruments available here.
