Velocity Keyboard vs Tera Pro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Velocity Keyboard
This app offers a versatile MPE MIDI controller with advanced velocity sensing and multiple interface layouts. It provides extensive MIDI CC control and flexible modes for both MPE and non-MPE synthesizers, enhancing musical expression.
- Advanced velocity sensing algorithm
- Four interface layouts (Keyboard, String, Scale, Drum Pad)
- Standalone app and Audio Unit support
- 8 simultaneous MIDI CC sources
- Smooth MIDI pitch bending
- Custom scale highlighting
- Pitch bend correction algorithm

Velocity Keyboard is a powerful velocity-sensitive MPE compatible MIDI controller. FEATURES - unique velocity sensing algorithm that tracks touch force like no other app - Four interface layouts: Keyboard, String, Scale, and Drum Pad - runs as an Audio Unit or as a standalone app - 8 simultaneous sources of MIDI CC parameter control: touch area, touch force (on devices that support 3D Touch), touch Y-coordinate, velocity to CC and up to four MIDI CC control knobs - smooth MIDI pitch bending between notes in both string and keyboard layouts - highlight custom scales in any key - dedicated MIDI modes for maximum flexibility when controlling non-MPE compatible synthesizers - pitch bend correction algorithm plays more in-tune with more freedom of expression when bending between notes (compared to similar MIDI controller apps) - can output velocity as a MIDI CC or aftertouch message to better support synths that aren't designed with velocity sensing in mind What does this app do differently from our iFretless apps? - It uses much less RAM because it doesn't load any audio samples - It has MIDI aftertouch controls, so changes in touch pressure and location that occur after after the start of a note can control MIDI CC parameters - It supports highlighting notes in custom scales - It has piano keyboard, scale, and drum pad layout options - It has updated velocity sensing and pitch correction algorithms - It has better visibility, making it feel more playable on smaller screens, or with a larger number of rows and columns

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...
