Tera Pro brings together all major sound synthesis methods on one table. No matter if you want to recreate sounds from analogue legends or explore modern digital sounds with FM, Waveshaping or Wavetable synthesis. More can be added by In-App Purchases of new modules. Add some flavour of physical modelling and modules for additive synthesis. Combine them altogether for new sound experiences far beyond your wildest dreams.
Tame this overwhelming amount of possibilities with Tera Pros intelligent user interface showing you only exactly what you need, paired with realtime oscilloscopes and level indicators helping you seeing what’s going on. Connect the modules with a flexible routing method without the visual cluttering of real wire cables needed in conventional modular synthesisers

FAQ What does Tera Pro have that Tera Synth doesn't have ?

1) Additional Sound Modules

- Spectrum oscillator ( borrowed from the heart of Addictive Synth )
- Wave shaper / folder opens the west coast synthesis
- Vocal Morphing filter
- KARPLUS (aka WaveGuide ) with new "Swarm" mode ( 3 detuned delays )

2) Revised engine

- Analog Polysynth Voice Modelling with characteristic subtle voice variations of timbre, pitch and temporal behaviour to get you "The" Analog Sound.
- 128 vs 32 voices polyphony
- Seamless Sound Switching: change presets during play without cutting off the sound.
- 8 times unison for really heavy ambients
- Envelope generators with Buchla style "end of cycle" trigger for generative music
- Stack/Split Sounds
- New effect section

3) Redesigned User Interface

- Collapsible modules for clear view of modular structure
- No more nasty popups for LFOs/Envelope generators
- Realtime oscilloscopes added to selected modules

4) New Presets

- About 1000 additional presets in there. Tera never sounded this good...

I’ve been learning about synthesis a lot lately and I’ve been going over my apps I let collect dust and I came across Tera Pro. I’ve had this since it came out, it has tons of beautiful presets but I never realized the power it has until I started sound designing my own patches. MAN anything from basic synths to crazy far out spacey sound FX, this synth is a beast. I really like how you can see how the oscillators effect each other in the chain via the numerous oscilloscopes that are in this app.

If you’re just getting into making your own patches, I feel this is a great synth to start with because as you learn, u can make more complicated sounds with the same kind of building blocks. If you’re not into sound design, there are plenty of beautiful sounds included, not to mention the randomize button, which has produced me tons of playable patches that I liked or had to tweak just slightly for it to sound good.

Love this developer and coming from Drambo as my main DAW .. this work flow makes sense and goes hand and hand.

Thank you for this app. Much love!

Good! But...

We still need a quick-access key-hold button. Burying it in a menu hidden in the Common module makes it pretty much non-existent in any active playing mode.
I am a big fan of the original Tera. Tera Pro is even better in many respects but it has additional versatility and functionality that make it a little more cumbersome to use. Sound quality is great and it is very flexible I have only one serious gripe. The "keyhold" feature (acts like a sustain pedal on a switch) is buried in a menu. This makes it almost useless. Look at ANY synthesizer -hardware or software- and you will find the "hold" button is immediately accessible. Please move the key hold feature to the main screen. It is an important live-performace feature. Why anyone would bury that in the settings menu remains a mystery. Very awkward. For my purposes (live performance) this reduces Tera Pro to only 3 stars, mostly becasue it is just such a dumb mistake and it really does make it harder to use what should be a mindlessly simple but important feature. Fortunately this SHOULD be a very easy fix for the developer.

No way to reset MIDI Learn controls

Tera Pro stores the MIDI Learn settings you make with your current MIDI controller and never gives you a way to clear them. Wherever they’re stored, you can’t find them on account that this app installs to a hidden file structure on your iPad.

Because of this, the app does not appear in the Apple Files app, nor does it appear in the iPad’s Settings where all your other apps are listed in alphabetical order. You can do a Search on Tera Pro in the Settings and it finds nothing. Why hide the app, guys?

To the guy with the Key Hold issue. Assign it to an on/off style button on your MIDI controller and set it with TP’s MIDI learn. You’ll always have it. If you ever switch to another MIDI controller, just uninstall TP to clear the old MIDI controller setting, re-install TP, and lastly, use MIDI Learn one time in TP to assign Key Hold to a button on your new MIDI controller. It’s a solution. A ridiculous one, at that, but it’s a solution.

I see a hardware synth in my future. I’m getting very tired of software synth glitches. TP is not the only one, for sure. Some are resource hogs, some have bugs, some have design flaws, etc. But all these software issues waste a lot of time. How much is your time worth? Time is all we have; you can’t get it back or buy more.
