MIDI Tools is a suite of AUv3 MIDI audio units for iOS that lets you manipulate the MIDI messages inside your DAW’s effects chain, creating complex or otherwise impossible MIDI routings or effects. The app contains 8 MIDI audio units in a single package, which can be loaded in compatible hosts (BeatMaker 3, Cubasis 2, AUM, ApeMatrix etc.). Make sure your host is capable of loading, transmitting to, and receiving MIDI from audio unit MIDI effects. They’re intended to augment existing MIDI processing capabilities, or in scenarios where a host doesn’t provide the required functionality out of the box. 1) MIDI Curve: Alter velocity or aftertouch values (0-127) in a controlled or random manner. 2) MIDI Key Zone: Transpose and restrict the playable key range. Perform velocity fades across various pitch ranges. Generate polyphonic chord fade effects. 3) MIDI Monitor: Monitor MIDI events in an effects chain, with detailed reports. 4) MIDI De-Ghost: Tempo synced trigger block, useful for hardware pad controllers that double-trigger, or removing ghost notes. It can also be used creatively to generate polyrhythms and gate-shifting effects. 5) MIDI Route: External MIDI routing capabilities. Route MIDI to external hardware, loopback to other tracks or banks. Record MIDI audio units generator output in DAWs which lack the ability to perform complex in-app MIDI routing. 6) MIDI Bus: Internal MIDI busing capabilities, designed for DAWs which lack the ability to perform complex in-app MIDI routing. 7) MIDI Latch: Enable latching and sustain capabilities, in any DAW that supports MIDI audio units. 8) MIDI Clone & Filter: Clone and filter incoming MIDI across different channels, in any DAW that supports MIDI audio units.

Create your own MIDI plugins: MIDI filters, generative music tools, basic sequencers, MIDI control panels, chaos experiments... Let your imagination take you places. Mozaic runs inside your favorite AU MIDI host, and gives you practical building blocks such as LFOs, pre-fab GUI layouts, musical scales, AUv3 support (with AU Parameters, transport events, tempo syncing, etc.), random generators and a super-simple yet powerful script language. Mozaic even offers quick access to your device’s Tilt Sensors for expressive interaction concepts! The Mozaic Script language is designed from the ground up to be the easiest and most flexible MIDI language on iOS. A language by creatives, for creatives. You’ll only need to write a few lines of script to achieve impressive things - or to create that uber-specific thing that was missing from your MIDI setup. Check out the Programming Manual on Ruismaker.com to learn about the script language and to get inspiration for awesome scripts of your own. Mozaic comes with a sizable collection of tutorials and pre-made scripts which you can use out of the box, or which can be a starting point for your own plugin adventures. Features in a nutshell: - Easy to learn Mozaic Script language: easy to learn, easy to read - Sample-accurate-everything: the tightest MIDI timing possible - Built-in script editor with code-completion, syntax hints, etc. - 5 immediately usable GUI layouts, with knobs, sliders, pads, etc. - In-depth, helpful programming manual available on Ruismaker.com - Easy access to LFOs, scales, MIDI I/O, AU parameters, timers - Supports Sysex, with built-in checksum calculations - AUv3; so you'll get multi-instance, state-saving, tempo sync and resource efficiency out of the box Mozaic opens up the world of creative MIDI plugins to anyone willing to put in a few hours and a hot beverage or two. Practical notes: - Mozaic requires a plugin host with support for AUv3 MIDI plugins (AUM, ApeMatrix, Cubasis, Auria, Audiobus 3, etc.) - The standalone mode of Mozaic lets you edit, test and export projects, but for MIDI connections you need to run it inside an AUv3 MIDI host - MIDI is not sound; Mozaic on its own does not make noise... so bring your own synths, drum machines and other instruments! - AUv3 MIDI requires iOS11 or higher
