HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (0.4 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ This is a bit like Mugician and Cantor as far as the incredible interface, I'm not real fast on a iPad keyboard graphic, but the way these apps are laid out I can seriously fly.

Bad sound

This app works great on my older iPad but it has a glitchy sound on my iPad Pro it sounds like it is not running at the correct bit rate.

★★★★★Feb 20, 2021
Abandoned

Geo Synth is just a fun toy anymore. Jordan has collected his money and has now abandoned it. It had such potential. It’s too bad. I wonder what Jordan is hawking now.

★★★★★Oct 27, 2019
Disappointed.. :( no updates in the past 3 years

I love the tones in this synth but there hasn’t been an update for 3 years which disappoints me

★★★★★Dec 9, 2018
Great interface but...

Needs an update to work with Bluetooth midi. I really love this interface but can not get it to work with Bluetooth midi.

★★★★★May 17, 2018
Not working with GarageBand

It does not work with GarageBand it does work with other synth but the tutorial shows it with GarageBand and that’s what I was looking for.

★★★★★Jan 20, 2018
Such a waste of money!

I’m a keyboardist and I’m not happy with this app at all. While the Geoshred is the holy grail of the guitar emulation, I was expecting to have the same feedback on synthesizers on this app. I was wrong. Such a ugly interface and nothing intuitive, this app is such a waste of my money, and I want it back! It’s not fair paying $10 on something I would literally throw in the trash can! Why I cannot have my refund on this??

Store description

Geo Synthesizer is a musical instrument and MIDI controller. Originally a collaboration of Wizdom Music's Jordan Rudess and Kevin Chartier (MorphWiz, SampleWiz) and Rob Fielding (Mugician), Geo Synthesizer is an incredibly expressive musical instrument specifically created for a multitouch surface. Jordan is now working with Roli-Labs, creators of the amazing Seaboard instrument on an exciting future for Geo Synthesizer and it's users! A comprehensive Geo Synthesizer manual is available at: http://www.wizdommusic.com/GeoSynth/manual.html Jordan says: "Since touching a preliminary piano keyboard on an iPhone screen and realizing the amazing potential for musical expression on a multitouch device, I have been inspired to create next-generation musical instruments for iOS. Geo Synthesizer is a dream come true in many ways. It is the fastest truly playable iOS instrument that I have put my hands on to date. I can fly through the range of an instrument while expanding on the kind of advanced pitch control we introduced in MorphWiz. As someone who grew up with synthesizers, I can tell you that pitch bending has never been this good! "Geo features many of my custom sounds and in addition, Geo is also a MIDI controller, so you can use it with any external midi instrument or virtual MIDI. Virtual MIDI allows you to control an app running in the background on the same device! Geo Synthesizer also now features AudioBus, a technology that allows one to interconnect audio apps in exciting new ways! A great feature of Geo is that internally and externally we send independent voices on each note played, so as an example, you can pitch bend one note and not the other, or add unique expression on every note! I can't wait to see the YouTube videos of all of you guys rocking out with Geo Synthesizer!!!" Features: - AudioBus - ability to load waveforms from SampleWiz presets - octave rounding for effortless soloing over large ranges - whammy slider with absolute and relative modes - 12ET, 24ET, 53ET, and 665ET temperament options - mono, string, and full-polyphony modes - tuning and transposition controls - snap speed control to affect how quickly the instrument pulls notes in tune - playing surface options for number of rows and columns on screen - octave and fifth harmonics synthesis options to rich, organ-like sounds - gain control to add distortion to the sound - FM and touch FM controls for timbal variation - mono out for use with guitar amps - sine, sawtooth, square, and custom (SampleWiz) wave options - attack and release controls - synthesis body control - lowpass filter with resonance - stereo delay - reverb - MIDI output with polyphonic note bending and multiple configuration options to allow compatibility with a wide range of hardware and software synthesizers - performance menu lets you make your own custom menu so all the controls you need are always right at your fingertips - 40 presets carefully selected by Jordan Rudess, including patches from Jordan's personal sound library
