TC-11 is the only fully programmable multi-touch synthesizer for the iPad. Choose from the 160 included presets, or build your own using touch controls, device motion, and on-board modules. Create music with the next evolution of synthesizer control! iDesignSound App of the Week 12.17.2011 - idesignsound.com "This thing is ALIVE! TC-11 is really fascinating and I'm having some fun experimenting with it. It is very, very cool!" - Jordan Rudess, keyboardist, Dream Theater "TC-11 is making my jaw drop every few minutes; realizing new and increasingly complex routing options. Rating: Essential." - Tim Webb, discchord.com "Creating, routing, configuring, and general tweaking is unbelievably robust and complex. This is a big leap forward in design. A madhouse of sonic possibilities at your touch." - David Israel, smitematter.com FEATURES: √ 185 built-in presets √ Unlimited user patches √ Audiobus + State Saving √ Fully controlled by multi-touch / device motion √ Built-in recording + AudioCopy √ 23 modular synthesis objects √ 22 oscillator waveforms √ 4 controller modules: AHDSR, LFO, Table, Sequencer √ Email custom patches to your friends √ Full display customization MULTI-TOUCH CONTROL: There are no on-screen knobs, keys, or sliders to fiddle with; all synthesis is driven by your multi-touch performance. Touch relationships like distances / angles / timings perform all the controller functions. It's just you and the full screen multi-touch performance area. EVERY synthesis parameter can be controlled by ANY multi-touch controller. The patch possibilities are limitless! DEVICE MOTION CONTROL: Use the iPad's accelerometer, gyroscope, and even the compass to attack your synthesis patch! Tilt and move the iPad to change any filter, effect, or module. You can create real vibrato by moving the iPad during performance, or change the speed of a sequencer by tilting forward and backward! SYNTHESIS: TC-11 has 8 voice polyphony for full, real-time synthesis. The audio engine has been highly optimized to deliver crisp, responsive performance. Choose from 22 oscillator waveforms, 3 oscillator types, 3 filter types, 4 unique effects, amplitude modulation, and panning control. Fully programmable AHDSR, LFO, and sequencer modules make TC-11 the most capable iOS synthesizer in the world. Use TC-11 in your band during live performances. Add TC-11 into your laptop orchestra.

Augmatic GRE
Generate complex and evolving drum patterns using algorithmic and Euclidean engines. This app creates MIDI notes that require a separate sound source to produce audio, offering deep control over rhythm and dynamics.
- Algorithmic and Euclidean rhythm generation
- Morphable Grids Engine for evolving beats
- Blend control between pattern types
- Linear drumming for articulate patterns
- Velocity bender for expressive dynamics
- Groove tools for swing and timing

MAIN FEATURES: - 6 Algorithmic Channels - Bass drum, snare, hi-hat, plus accents which create complementary rhythms, not duplicates. Each channel can generate its own rhythmic voice for rich, layered drum patterns. - Topographic Engine - Morphable, evolving beats based on the Mutable Instruments Eurorack module. Navigate an X/Y map of interconnected drum patterns extracted from actual drum loops with smooth interpolation between patterns. - Euclidean Engine - generate evenly distributed, world‑inspired rhythm patterns using Euclidean algorithms. Configure steps, hits, and start position independently on each channel for precise control. - Blend Control - Crossfade between Grids and Euclidean patterns to introduce variation while preserving the core character of your groove. - Linear Drumming - Control which drums play together or play alone. Eeach sound has room to breathe. Creates clean, articulate patterns. Used in Hip-Hop, IDM, Funk, Fusion. - Velocity Bender - Shape velocity dynamics for a more expressive, dynamic pulse. Create ghost notes, and rhythmic emphasis that bring patterns to life. - Groove Tools - Swing, humanization, clock division, and timing shift. Fine-tune the feel of your patterns from tight and mechanical to loose and human. IMPORTANT: This app does not produce sound on its own. It generates MIDI notes and requires a drum sampler or synthesizer to play them.
