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.

Really Excellent Sounding Synth

The variety of sounds this synth can produce and the quality of the sound it produces are certainly worthy of much praise. Now with AUv3 it will get even more use than before.

Tera is a winner.

Recorder doesn’t work

After making several recordings, discovered they do NOT appear in the iTunes file sharing window. They can NOT be pasted into other applications, do not export into Audioshare or Audio paste, cannot be shared via Airdrop (says “failed”) cannot be saved in Dropbox (says “error”), and cannot be mailed (crashes the program). Basically, any recordings made within the app are unusable.
