About RS-CHOIR
Unleash the full voice of your choir. RS-CHOIR is the ultimate companion app designed exclusively for the Teenage Engineering Choir. Whether you are a composer, producer, or live performer, RS-CHOIR equips you with powerful tools to compose, sequence, loop, and harmonize in real-time. Transform your choir into a fully customizable vocal ensemble with four intuitive modes and advanced synchronization features. FOUR POWERFUL MODES ****Loop & Edit: Play your choir using a multi-octave virtual keyboard. Capture your inspiration with four dedicated recording loops to build complex, layered harmonies. Need perfection? Use the manual note editor to fine-tune the pitch and length of any note until it perfectly fits your vision. ****Sequence: Arrange complete, evolving song structures by chaining up to 16 unique patterns. Define single notes or full chords for every step. Don’t just play notes—play words! Assign specific vowels and consonants to craft custom lyrics and vocal articulations. ****Sing: Turn your Choir into your personal backup singers. Simply tap to latch your microphone, sing a tone, and listen as the Choir seamlessly harmonizes with you in real-time. ****Play: Effortlessly save your compositions and play whenever you want. You can also load MP3 backing tracks that play in perfect parallel with your choir, giving you a massive, full-band sound. ADVANCED PRO FEATURES Native Gear Sync: RS-CHOIR isn't just an isolated app. Send an audio master clock sync pulse directly from your device to perfectly time your Choir with external gear, including Teenage Engineering Pocket Operators, modular synths, and other grooveboxes. AI Song Generation: Generate entirely new songs in seconds! Use our built-in AI workflow and optimized prompts with your favorite AI chat to generate fresh song data. Paste it back into the app, and your Choir will sing a brand-new, original piece. Full Vocal Integration: Bring your choir to the next level. Move beyond simple melodies by adding dedicated vocals and articulations to your masterpieces. Ready to start conducting? Download RS-CHOIR today and bring your vocal arrangements to life.
