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.

Virsyn keep on delivering

Got to hand it to Virsyn, they make great products then keep them great by constantly updating them as iOS evolves.

Great sound but poor interface

Anyone with fingers will find this very hard to program and a stylus is highly recommended.
The sound quality is stunning. I’ve used it live twice. Once played from an Arturia Keystep and once from it’s own interface.

Quite CPU intensive for my iPad 5th generation. The audio clicks under certain conditions, which I suppose are dependent upon the intensity of the process.

You are spoiling us....

Weirdly, given my deep love for Addictive, I'd spent a whole week in it, trying to make a tune out of its sounds alone. It was pretty easy, VirSyn make wonderful instruments, Addictive being one of the first iOS synths and still holding them back in certain quarters.
Then this appeared, an obvious buy. What a treat! It's by far the most twiddly, widdly app yet, its insane to the ears. Reminiscent of the JD800, it sounds great, but there's too much temptation to move some sliders, 3 touches on, the sound is vastly different and taking you on a little journey that has no defined conclusion. The patching is pretty simple once you've caught the groove, it help if you're familiar with their earlier work, Addictive, Cube and Micro all have the same workings, so you can get straight to the nonsense and cut out the sanity.
If you've used their arp, you know it's hard to beat, no exceptions here, apart from not actually wanting to use it and let the notes carry on their merry way.
It's no beginners machine, it could cause much confusion, but to someone who's looking for the next ride into space, get on board immediately,switch the lights off and fiddle until the dawn.
My epic Tera only tune will be released in 2024, I'm not going to rush it...
