Scythe iOS app is designed for iPad. It has a powerful synthesis engine and makes it easy to create and discover sound designed.

The wavetable creator enables the creation and editing of wavetables and is integrated directly into the system to preview your creations with the current session status. You can override the oscillators to see how your creation mixes with your session's sound.

The controls have been minimized to allow a simple workflow with the same complex modulation that you might be used to. If you are new to modulation, Scythe app for iOS makes it simple with drag and drop, from source to oscillator control.

Now with CoreMIDI and Audiobus Midi input and Inter-App-Audio, Scythe synth can be integrated into your studio or workflow.

Scythe synthesizer iOS app comes with presets and library wavetables for quickly hearing some of its possibilities.

AudioShare allows importing and exporting audio with Scythe synthesis iOS app easily.

Generate custom wavetables by importing your sounds using AudioShare or iTunes file sharing, record using IAA out or directly in Scythe synthesizer app and export using Audioshare or iOS sharing options.

Please note for best wavetable generation results, sounds with low frequency content or enough spectral content is required.

Excellent synth!

This is one of my fav synths. The UI of any app is very important, and the UI of this synth is one of the best I’ve seen. Color coded controls so that when you apply LFO1 to something, it will turn that color. Might not seem important, but it really is, improves experience by far vs some other synths that have no indication of what’s controlling what. On/off buttons for the envelopes and LFOs and each item inside the matrix. 💕

The most important thing about any synth is the actual sound quality - which is great here. You can do all kinds of crazy sounds or more smooth ones, depending on the audio you drop on it. Just load up a sound file and use the controls to play with it. There’s no overwhelming amount of features - 2 filters and 3 LFOs that can control every knob, but the sounds you get out of this synth are very usable in a track. Just about anything I drop on this seems to give me pleasant results, and very different too. Glad I discovered this one. AUv3 would make it perfect, but at this price you just can’t go wrong! There are a lot of synths out there but the only non-AU ones that I would buy again are this one and Nave.

Edit: the knobs are fixed, and they operate smoothly now. Thanks! Pops are fixed too. And waves are playable directly.

Developer Response ,

Hello. The pops are now fixed when releasing a note on certain wavetables and the wavetable creator has a preview mode, integrating directly into your current session.

Grrat synth, great developer

I like this synth a lot. Sounding great and modulation is easy to understand. It didn't take me long to build some cool sounds from scratch and modulate the controls. I also really like the user interface which is pretty user friendly imo.

The IAP for thr waveform editor is very cool too i think. Fantastic way to experiment with finger drawn waveforms or combine them with other shapes. Highly recommended app and IAP if you are into crazy and experimental synth sounds or soundscapes.

This app deserves the full five stars also because of the developer which has been very fast with adding requesting features in the past and also fixing recently reported bugs. Top class support for an awesome synth.

Cool app

I find the app to be very well thought out. I’m writing this review after just a day of using and will update it, hopefully by adding another star, or two. Unfortunately it crashed once on my iOS 13 iPad so far when using Wavetable Creator.

The Inter App Audio either does not work or I can’t figure out how to use it. When selected as an input in Audiobus and linked into an output app, the sound in the app is muted and nothing can be recorded out of it. When used in GarageBand with its own IAA capabilities, GB says that the Inter App Audio of Scythe is not available. I tried using other apps as a destination, with and without Audiobus and it just does not work. If this is a paid feature, it is unclear which item in the store needs to be purchased to enable it

I wish that importing sounds to be used as a basis of the wavetable was more straightforward. Yes, Audioshare is straightforward but can’t the app simply access Files app to import a file? ITunes File Share? Hopefully the word “iTunes” will be forgotten, this great app should not keep it alive in any form.

I think there’s a bug which prevents me from using a split mode of the keyboard. When I press it, the keyboard becomes translucent but I can’t figure out how to make it reveal the modulators. I tried pulling it into different directions but modulators can’t be seen.
