Description

Transform your MIDI performance with Terca & Scala Engine, a professional real-time MIDI processor for your external hardware instruments.

Designed for live performers, studio producers, and composers, our engine processes MIDI data from your hardware synthesizer or arranger, adds new musical dimensions, and sends the result back to your instrument instantly. Simply connect your MIDI hardware and let the app become the brain of your setup.

IMPORTANT: This app does not produce any sound on its own. It is a MIDI controller and processor that requires an external hardware MIDI instrument (like a synthesizer, arranger, or sound module) to function.

KEY FEATURES

"Terca Engine" - The Intelligent Harmonizer:

Real-Time Diatonic Harmony: Play on your hardware instrument, and the app instantly generates a musically correct second voice, sending it back to your instrument on a separate MIDI channel.

12 Unique Harmony Modes: Instantly switch between 12 distinct harmony styles, including natural major/minor, melodic, harmonic, Hijaz, and more.

Bordon (Drone) Mode: Creates a constant, accompanying root note beneath your melody, perfect for folk and ethnic music.

Quart Note Function: Assign a specific note in the scale to always be harmonized with a perfect fourth, creating characteristic folk intervals.

"Scale Editor" - The Microtonal Powerhouse:

Microtonal Precision: Tune any of the 12 notes of the scale with cent-level accuracy (from -99 to +99 cents). Recreate the unique sound of Maqams, Balkan folk scales, or your own experimental tunings.

Powerful Bank & Patch System: Organize your work like a pro. The app offers 6 user banks, each containing 6 patch slots, giving you 36 locations to save and instantly recall your unique scales.

Dynamic Pitch Bend + Static Tuning: Our engine works intelligently. It applies your static note tuning while preserving and adding the dynamic Pitch Bend from your controller, keeping your performance expressive.

Professional Workflow & MIDI Control:

Smart Transpose: Does your hardware instrument's transpose setting not match your playing key? Set the same transpose value in our app (for both Terca and Scala engines independently) to ensure all generated notes are always musically correct.

Advanced MIDI Channel Routing: Full control over your MIDI channels. Choose between "Arranger" mode (optimized for arrangers sending on multiple channels) or "Synthesizer" mode. Manually enable or disable any of the 16 MIDI channels for processing and save your configurations.

Expressiveness Preserved: The app intelligently passes through key MIDI messages like Pitch Bend, Modulation (CC#1), Volume (CC#7), and Expression (CC#11), maintaining the full sensitivity and dynamics of your performance.

WHO IS IT FOR?

Terca & Scala Engine is built for every musician using external MIDI hardware:

Keyboardists & Accordionists with MIDI

Folk, Ethnic, and World Music Performers

Live Performers looking to create a richer sound without a second musician

Users of MIDI Guitars, Wind Controllers (EWI), and other alternative MIDI controllers.

REQUIREMENTS:

An iPhone or iPad with iOS/iPadOS 15.6 or later.

An external hardware MIDI instrument (synthesizer, arranger, sound module, etc.) that can send and receive MIDI data.

A compatible USB interface (like the Apple Camera Connection Kit) to connect your instrument to your iOS device.

Terca & Scala Engine 2.0: The Pro Update!

Get ready for a massive upgrade! Version 2.0 transforms Terca & Scala Engine into an even more powerful tool for professional musicians. We've rebuilt key features from the ground up based on your feedback.

What's New in Version 2.0:

Completely Revamped Custom Interval Editor: We've introduced a revolutionary new system in the "Custom" screen. Now you can assign a unique harmonization interval to each of the 128 MIDI notes individually! This gives you unprecedented control to create complex, dynamic tercas and harmonies that can change depending on the note or octave you play.

Real-Time Audio Preview: Hear your changes as you make them! While in the "Edit" menu of the Custom screen, you can now play your physical MIDI controller and instantly hear the harmonized note based on the interval you're editing. This makes creating the perfect custom preset faster and more intuitive than ever.

Save & Load Your Presets: Your creativity is now saved! We've implemented a full-featured preset management system for both the Custom and Scale screens.

Save: Easily save your individual custom tercas, scales, or even entire banks of presets as files directly on your device.

Load: Bring your saved presets into any slot with just a few taps. Build your own library of sounds and load them whenever you need them.

Manage: Loading a preset is simple and intuitive, with a clear list of your saved files. You can also delete presets you no longer need directly from the load menu.

This update is all about giving you more power, more flexibility, and a faster workflow. Thank you for your support, and we can't wait to see what you create with Terca & Scala Engine 2.0!
