This synthesizer offers a brand new way of finding the optimal sound. By rotating a sphere that consists of more than 70 professionally created states anyone can dial in the perfect sound. In addition to the sphere, a ping-pong delay and a few more global settings are available.

SyndtSphere is based on the more traditional polyphonic synthesizer Syndt (also available on the App Store).

A video demo is available at the developers website.


• AUv3 Compatible - use it as a plugin inside Garageband or any other AUv3 compatible host app.
• High quality internal audio engine.
• Stereo ping-pong delay
• Optional legato mode with glide speed setting.

nice selection of synths

easy and fun.not overly complex but thats the point.

Nice idea, but ...

A lot of the sounds have VERY strong oscillation profiles! (is this intended or is it a bug?) In other words, a very intense pitch warble and (imho) are out of control on some of the sounds and make them totally unusable. Any of the oscillations that control either the amplitude or tone are not as bad, but I would still like to be able to control them. And for me personally, a lot of them are not useful because of that. I see the potential and I like the core sounds and I like the idea of blending between them, but, I need to be able to control the intensity of these oscillations, even if it's a global setting. Two dollars won't break the bank, however I'd hate to see this app go to waste because it ended up in my "great in theory but not in practice" app heap.

Rivera guitar amps are best ,


It really is a sphere! The 2D representation effectively visualizes the 3D space of the sound designer. I'm enthralled by the sounds one can create while turning the sphere in endless directions. And fine tuning the sounds is a journey of discovery in itself. I haven't even synced it up yet with an AUv3 host to introduce the tempo control and still I'm blown away. This is a fun way to design sounds.
