An upright piano sits perfectly in pop, R&B, Hip-Hop, and many more modern music genres. That’s why it’s heard in countless iconic tracks throughout musical history with the upright at the heart of the song. You don’t always need the splendor of a grand piano but the character and immediacy of an upright piano. Pure Upright captures the uniquely recognizable sound of the upright piano and makes it as wonderfully playable as our acclaimed Pure Piano for iOS.

Similar to an XY pad in its flat, tactile nature, the Morph Pad offers up nine different core upright piano timbres, including Vintage, Intimate, Reverse, Gated, and Pad, to name a few. The “pure” Upright sits untouched at the heart and center of the space, surrounded by eight more presets for you to explore as you guide your finger seamlessly through the wide-ranging tonal palette of the piano. As you do so, the various timbres blend together, allowing you to create your own sounds comprising combinations of neighboring presets for you to save and recall.

Pure Upright works as a standalone app or as an AUv3 plug-in within your DAW of choice, and extensive connectivity options allow you to easily connect to your keyboard controller via USB, direct, or Bluetooth MIDI to experience the sound of a professional grand piano through your headphones or speakers. The app also supports a direct connection to your Mac using Inter Device Audio (IDAM). This enables you to easily integrate Pure Upright into your desktop projects by sending MIDI and receiving audio with one single cable, as well as network MIDI and Inter-App Audio for triggering the piano from other apps that you might have installed.

Equipped with customizable reverb, EQ, and delay, sound creation becomes even more creative. Simply unlink any of the audio effects from the Morph Pad to dial in your own settings. Maybe you want to add a long reverb tail to add some extra atmosphere, tweak the EQ a little or add some delay to a particular sound. It’s up to you.

If all that isn’t enough, the app includes sympathetic resonance which you can adjust along with the pedal and key noise to taste, and there’s a host of flexible tuning options for when you need them. The stretched piano tuning is how a piano technician would tune the piano. The equal temperament tuning, on the other hand, is best for when layering Pure Upright with sounds like electric pianos, pads, or strings. Also provided is the ability to transpose the piano which comes in very useful if you are working with a vocalist who wants to sing in a different key!

For the best experience with Pure Upright, we highly recommend using a controller keyboard to trigger the notes so that it feels like you’re playing a real upright piano. The on-board velocity response page allows you to match the dynamic response of Pure Upright to your keyboard controller and your playing style so that you can achieve the right velocity response for you and the song you’re playing.

Pure Upright is designed and developed by Hamburg-based e-instruments, renowned for their high-end digital recreations of acoustic instruments.

I know these guys

And I know you won’t regret your purchase.

That being said… this is “NOT” iOS 13 compatible, you tricked me there! I can’t download on my 13.7 iPad. You need at least iOS 14.

Anyway, lucky for me I have another device with the proper iOS so I can use that for now.

Straight up haven’t even booted the program but pure piano has been one of my favorites for a while so I have a hard time believing I won’t just fall in love with this one.

Polyphony Cuts Out Randomly

Using this as a live piece is apparently a no go. Audio randomly cuts out from the previous note which means it has the same polyphony problems as other less expensive plugins. A bit if a disappointment considering its cost and how good it sounds when it is functional.

Developer Response ,

Thanks for your review. The problems you describe seem to be related to the settings. Both Pure Upright and Pure Piano use active "Liquid Morph" as the default setting. What it means is, that a held chord can be morphed in sound on the Morph Pad. This feature needs quite a lot of voices in the background to work and maybe you don’t need it at all. If you deactivate “Liquid Morph” in the settings, you should get a higher polyphony. Held notes will no longer morph, but all newly triggered ones do anyway.
Additionally, you should take a look at the "Voice Mode" setting. Since you have a powerful device, you can set it to "Max".
If you still experience any tail cutting, please contact our support via e-instruments.com/support/
