Tera Synth - Modular Analog Synthesizer

Explore new sound spaces with Tera Synth that go beyond the emulation of synthesizer legends. Use the power of analog and digital synthesis combined with new modules for physical modelling. Wireless patching of modules combined with an intelligible modulation routing simplifies the development of new synthesizer designs from scratch. Distortion effect, Delay/Chorus/Phaser and Reverb effects give your sounds the final polishing. Tera Synth gives your music an individual character with its unique fat sound. The well-designed algorithms and the economical modular structure provides you with a comparatively high voice yield. Precise timing with the unique built-in Arpeggiator let you feel the rhythm.

Tera Synth supports Audiobus and Inter-App-Audio for integration with other Music Apps.

I’ve just spent a few minutes creating my first patch and, already, I’m in awe of the balance between depth and simplicity in this modular synth. The ease with which one may modulate nearly everything with almost anything is breathtaking, and the waveform options are great.

Of course, the mind can’t help but wonder what would happen if all the effects parameters were modulatable, but with 3 oscillators, 4 LFOs, 4 insane envelopes, and a sequencer, I feel confident that I’ll have plenty to explore.

Next, I’ll have to test how in runs in AUM and AB3.

A real update would be auv3

Great synth, easily one of my favs, but in all honesty.... I'd be a lot more excited update wise if this became an audio unit. I use addictive pro more than this now because it's an audio unit and I can use it directly inside of Beatmaker 3, Cubasis and Auria pro. Any update that doesn't support audio unit is kinda...meh.

AU3 addition is a great free upgrade but it doesn’t work

I was excited to see the AU3 support added, but I haven’t been able to get it to work using AUM on iOS11. In the update description you list iOS10 required. Does this mean exactly iOS10 or “at minimum” iOS10. I don’t want to downgrade.

Developer Response ,

Sorry for the confusion - iOS 10 is minimum requirement, iOS 11 is perfect - no need to downgrade !
