TC-11 is a groundbreaking multi-touch synthesizer for iPad that redefines how electronic music is created and performed on mobile devices. Available on the Apple App Store, TC-11 is widely regarded as one of the most expressive modular synth apps on iOS, combining deep sound design with fluid, performance-driven interaction.

Developed by Bit Shape Software, TC-11 replaces traditional knobs and sliders with a full-screen multi-touch control surface, allowing musicians to shape sound through gestures, movement, and timing. Every synthesis parameter can be controlled via touch relationships such as distance, angle, speed, and pressure, making it a powerful gesture-controlled synthesizer and a favorite among experimental composers and live performers.

At its core, TC-11 is a highly flexible modular synthesis environment featuring over 20 oscillator waveforms, 23 synthesis modules, and multiple controller types including ADSR envelopes, LFOs, tables, and sequencers. Users can start from more than 180 built-in presets or design unlimited custom patches, making it ideal for sound design, ambient music, electronic composition, and avant-garde synthesis.

TC-11 integrates smoothly with the wider iOS music ecosystem, supporting tools and platforms such as Audiobus and AudioCopy for routing and exporting audio. Built-in recording and state saving enable seamless workflow integration, making TC-11 a serious music production app for iPad rather than a simple synth toy.

The app has received critical acclaim from industry experts and artists, including Jordan Rudess of Dream Theater, who praised its expressive depth and creative potential. TC-11 was also recognized as App of the Week by iDesignSound, cementing its reputation as a must-have iPad synthesizer.

Whether you’re exploring experimental electronic music, building complex evolving textures, or performing expressive live sets, TC-11 stands out as one of the most advanced touch-based synthesizers on iOS. With limitless routing possibilities and performance-driven design, it remains a top choice for musicians seeking a professional iPad synth, modular sound engine, and creative music app all in one.
