Chih Han Lin has updated Contour, available as a FREE download which unlocks the Pro version.
What’s new in version 1.0.3:
The composer plays each set of corners to you, and a sheet you bake reaches the plug- in without reloading it.
- Tapping a mark always sounds. Once four notes were still ringing it went silent instead – and the ribbon moved to that mark anyway, so the mark looked half alive.
- Composing a sheet plays it to you. Stop moving for a moment and you hear the corners you have landed on. Before, you had to hold a note down with one hand and steer with the other, and nothing on screen said so.
- Dragging an axis is smooth. It was running the whole search again for every fraction of a millimetre your finger moved
- Brushing the axes no longer sends you back to the first combination. If the one you were listening to is still where it was, you stay on it.
- Auditioning no longer leaves a note sounding for ever if the corners change underneath it
- A sheet you bake in the app shows up in the plug-in while the host is still running. It used to need the plug-in reloaded, and nothing said that either.
- The host’s preset list is the sheet list – Logic’s Library, AUM’s presets. It was empty before.
- The marker on the plug-in’s map follows automation. MAP X and MAP Y moved the sound and the marker stayed where the note started: the map saving one thing and your ears another, which is the one thing this instrument must never do.
- Modulation keeps its depth however fast it runs. It used to grow shallower the quicker the LFO went, without you touching anything that says depth.
- A finger on the plug-in’s map tells the host it is being held, so the host’s automation gets out of the way instead of fighting it.
- The plug-in offers stereo only. A host could set it up with more channels than it has, and the extra ones carried whatever happened to be in the buffer.
Contour — Ambient Morph Synth offers an intuitive approach to generating evolving drones, deep atmospheric pads, and moving soundscapes directly on your mobile setup.
Rather than focusing on rigid, step-based sequencing or complex menu-diving, Contour centers its workflow around movement and timbre-morphing. The core idea is simple yet generative: seamlessly transition between complex timbral profiles to create continuous, living sound structures.
Whether you are composing film scores, generating backdrop textures for lo-fi beats, or crafting long-form ambient soundscapes for relaxation or meditation, Contour provides an interactive visual workspace that turns patch design into a fluid experience
Features include:
Sound Engine & Synthesis
- Morphing Engine: Advanced timbral interpolation for fluid sound-shaping between atmospheric states.
- Ambient Sound Generator: Specialized for creating evolving pads, rich tonal drones, granular textures, and cinematic backdrops.
- Custom Preset Library: A curated collection of factory presets tailored for ambient, experimental, and soundtrack production.
Control & Modulation
- Visual Interface: Clean, tactile control interface optimized for iPad and touch interaction.
- Dynamic Parameter Shaping: Deep control over filter contours, modulation rates, and envelope dynamics.
- MIDI Connectivity: Full MIDI input support, allowing you to play the synth using external MIDI controllers, touch keyboards, or host sequencers.
Integration & System
- AUv3 Plugin Support: Seamless integration as an Audio Unit v3 plugin in hosts such as AUM, BeatMaker 3, Cubasis, and GarageBand.
- Standalone Mode: Run the app independently for quick design sessions, live improvisations, or ambient background generation.
