It's not just an app, it's an instrument!

GeoShred Pro Version 5, with In-App-Purchases for GeoSWAM** instruments on devices running iOS 11.4 or greater.

Imagine a new kind of musical instrument ...

An instrument where a performer can fluidly express multiple independent voices. An instrument that is both pitch fluid, and helps the performer precisely reach desired musical pitches in any temperament.

GeoShred is an award-winning, fluidly expressive musical instrument that runs on multi-touch devices.

It has a performance surface with “almost magic” pitch rounding algorithms which is coupled with a model of the physics of several types of musical instruments, support for AUv3, MIDI In/Out, MPE, and 3D Touch. It’s a fusion of Jordan Rudess’ performance concepts and a powerful, modeled guitar/effects based on the Physical Modeling research of Dr. Julius O. Smith III of Stanford/CCRMA. And, GeoShred's expressive control can be used with other synthesizers.

Tens of thousands of artists in 48 countries perform GeoShred with 30% of those users in India.

GeoShred is the Gold Medal Winner of the 2019 Denny Award, winner of a 2019 Guthman New Musical Instrument Award, and winner of the 2017 Electronic Musician Editor's Choice Award as "one of the most innovative, groundbreaking products to emerge in the past twelve months".

Absolutely amazing instrument and controller - best I’ve ever played

At first, I wasn’t sure what to expect, but knowing that this came from the genius of Jordan Rudess, I knew that it wasn’t going to disappoint. I have to admit that at this point, this has completely blown my mind! This is the most playable instrument I’ve ever played, virtual or physical. Once you get the hang of how it works, I doubt you will be able to put this down before your fingers start bleeding!
I also love the fact that I can use this with AUM as a controller for other instruments hooked up in AUM. No other MIDI controller comes anywhere near close to the expressiveness that’s possible with this controller. I also have it on my iPhone 7 Plus which has 3D Touch and even on its small screen, this is amazingly playable. This is the kind of app that touch screens were made for and really showcases their potential. I can’t believe it took me so long to find this.
If you’re in the market for an amazing MIDI controller that’s playable and expressive, then your search has ended. Just hit that “BUY” button already!

Great modeled guitar with room for potential improvement

I personally love this app because it is exactly what I want as a keyboard player who loves guitars. I always prefer physical modeling to sampling in most cases so this is an dream to play. I feel like even though this app is already top of the line it could be pushed further by allowing more complex pickup configurations like both single coils and both double coils as well as split bridge double coil with neck double coil and split neck double coil with bridge double coil. Besides that it stands in a league of its own for what it does. I would absolutely recommend to anyone interested in physical modeling or having a more than useable guitar sound as a keyboardist.
Edit: maybe a new pickup could be made to model the ones on bass guitars to give a better tool for modeled basses in general. This app has been a near daily source of blues improv recently. Plus it is a great way to use swam instruments on iOS as long as your device is large enough. Geoshred has the great MPE controller layout that SWAM needs.

Amazing App, I shouldn’t have waited so long to purchase it.

I recently got GeoPro and some Swam sounds after only having GeoPlay, and it is a blast to jam with, set your scale, or even a custom scale and play. Just jamming is so much fun. I sometimes create a simple backing track in AUM, and go to town, It’s a blast. It’s AUv3, so inside a host/DAW it’s easy to record the audio from what I play into another Au app, then playing it back in a new way. It’s great for live playing but sequencing the app with midi is also great. All sounds are top notch. It’s also a MPE controller for all your iOS MPE needs. It’s so realistic and expressive to play. Geoshred pro is amazing and the new swam sounds put this app up there with the best of them. If you play guitar this is a definite must buy because the interface is designed in a similar fashion. It’s easy for guitar players to pick it up and play it fairly well right off the bat. But even if you don’t it sounds amazing and can be payed by anyone. Amazing App, I shouldn’t have waited so long to purchase it.
