HWM Midi Surface App Icon Introducing “HWM Midi Surface” auv3 iOS app

Release date coming soon….

The Modular Audio Unit MIDI Surface for Modern Producers.

Design custom touchscreen control consoles right inside your favorite DAW. Knobs, sliders, tactile pads, split keyboards, and DSP-grade ramp automation—engineered for sample-accurate live performance.

Bridge the Gap Between Studio Hardware and Touchscreen Precision.

Most software MIDI controllers force you into rigid, static layouts. HWM MIDI Surface turns your iPad and Mac into a responsive, modular studio console that you sculpt to fit your workflow.

Whether you’re automating complex filter sweeps in AUM, performing live splits in Logic Pro, or controlling multi-instrument rigs in Loopy Pro and Cubasis, HWM MIDI Surface gives you immediate, tactile mastery over your sound.

Feature Highlights (Modular Rack Units)

Build any console layout in seconds.
Drag, drop, scale, and snap your controls to an intelligent alignment grid. Create focused 4-knob macros or sprawling 32-channel master strips with zero clutter and canvas zoom lock for seamless live performance.

⏱️ DSP-Grade Hold & Ramp Automation

Smooth transitions. Zero clicks. Total musicality.
Inspired by professional commercial DSP and hardware VCAs, assign configurable Hold Off delays and Ramp Times to any momentary switch, trigger, or fader. Tap for stepped increments, or hold to trigger automated sweeps and ducking fades.

🎹 Integrated KeySplittr & Multi-Zone Keyboards

Split, layer, and transpose on a single screen.
Play two or three independent synth engines simultaneously without extra routing plugins. Set custom split points, assign independent MIDI channels and octave transpositions, and trigger multi-timbral patches on the fly.

🎚️ B3 Organ Harmonic Drawbars

Classic 9-drawbar tonewheel control at your fingertips.
Real-time physical drawbar control featuring authentic footages (16′16^\prime through 1′1^\prime), smooth drag articulation, and instant preset registration buttons for iconic gospel, jazz, and rock drawbar settings.

🎯 Sample-Accurate CoreMIDI Routing

Never miss a single CC message or automation trigger.
Built with a dedicated lock-free FIFO queue and real-time audio render block dispatching, every slider move, button press, and XY gesture is mathematically stamped to the audio frame for rock-solid host synchronization.

🎨 Engineered Studio Themes

Built to look and feel like high-end rack gear.
Switch between dark graphite Modern Console, industrial blue-slate Neon Platinum with illuminated jewel pips, high-visibility Bright Studio, and Soft Minimal to match your studio environment.
