Great Sounds. OK Interface. No Integration with GarageBand iOS

I really love the sounds - I’ve downloaded 2 pianos so far and I’m really enjoying the nuances in the samples. It’s a bit annoying that once I purchase a piano, there’s no way to find the name of that particular instrument (I have the black grand and the red grand, which I think are German/American and Japanese?).

The layout of the app is... OK. They could use some UX designers to make the layout cleaner.

The biggest disappointment is that it doesn’t show up as an option in iOS GarageBand to use as an external instrument. I’ve been looking for a great piano sound to bring into some of my iOS produced music, but I guess I’ll have to keep looking.

Incredible pianos especially for the money

I have pianos on my computer that cost a lot more and don’t sound any better and in often cases worse. The colossal piano is the “best”, but the white upright is just as inspiring in my opinion and much cheaper. In fact I’d say it’s the best deal bar none in Virtual Instruments. I’d give more stars if I could and I would definitely buy again w/o regrets. You do NEED an iPod/Pad/Phone with a headphone output. Bluetooth will have and unacceptable amount of latency as is the case on my computers as well. Maybe there are other Lightening adaptors that will work, but if all you have is the camera one, you need a headphone output in my opinion. Hopefully in the future they will add more incredible quality pianos! I like to try different sounds oftentimes and have a real affinity for vintage German uprights not to mention modern Seiler, Bechstein, Hoffman, Schimmel, Bösendorfer, etc... but some of those Grotrian, Steinway, Lipp, etc... blow my mind. Sorry for the little hint for the developers. I like collecting piano sounds like baseball cards.

High Quality piano sounds and great customer support

I’ve had the Upright Piano since shortly after they came out with this app. It’s a fantastic piano and a good all around sound. Works with rock based music, jazz, and sounds fine with classical as well. There was an issue with a sample on one of the layers of velocity on a single note. I emailed support and they quickly responded to say they will look into it. They emailed me 2 days later again to say that it was fixed and all I had to do was uninstall the piano and re-download it as they had the newly fixed version already uploaded. I wish I had emailed support earlier. I give them 5 stars as well as 5 for the sounds of the piano. I also have the less expensive Vintage Upright. It’s not as good as the Upright model, but they also charge you less and it’s a different sound for some extra variety. I’ll likely end up buying some other pianos at some point, but definitely don’t need them all.
