Reached #1 on the App Store in the Top Paid Music App Category. The most advanced AUv3 MIDI note editor, modular sequencer and clip launcher on iOS. Notes: - This plugin does not run as a standalone app and requires a compatible host. - MIDI is not sound. To make sound you'll have to feed the MIDI into a synthesizer or instrument app. Bring your own synths! - Hardware integration with controllers requires iCloud Drive. Compatibility: - Special integration with hosts: AUM and Drambo. - Tested hosts: ApeMatrix, Audiobus, BeatMaker, Cubasis, MTS, Zenbeats. Limited support by NanoStudio 2. Not supported by GarageBand. Build live sets for clip launching, or an entire track with unlimited length. Play the whole sequence, or adjust the loop markers to iterate over a single section. Step input, or record as played, all with perfect timing accuracy. Write your own code, share it with the community! You can control hardware devices, adding support for new controllers or completely changing the behavior of existing ones. Build your own styling with custom layouts and themes. Change colors, fonts, sizes… make it yours! Piano Roll 2 takes all the features you love about the first installment, and expands them into an entirely new breed of modular sequencer and clip launcher, unparalleled in flexibility and depth on iOS. We redesigned it from the ground up to incorporate a plethora of new features and workflows. - It's a sequencer that augments the capabilities of your host or DAW. - It's a composition tool that helps you to write beautiful melodies and complex polyrhythmic patterns. - It's a clip launcher that integrates seamlessly with supported hardware controllers. - It's a scripting playground that lets you customize your workflow with code. - It's a swiss-army knife of possibilities when working with MIDI. Here are just some of the many use cases this modular architecture supports: - Build live sets for clip launching. - Compose patterns with touch, Apple Trackpad and Apple Pencil, or use the step input mode to write melodies step-by-step. - Capture performances in real time and export your patterns as MIDI files. - Import and edit MIDI files created in other apps, or from commercial packs. - Record generated MIDI of other plugins or sequencers. - Write harmonies and counterpoint melodies by superimposing the patterns of other Atoms as ghost lanes. - Construct complex polyrhythms by taking advantage of custom time signatures and grid fractions. - Sequence the sequencers for full modular mayhem.
