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

IMPULSation is an impulse response/convolution reverb that allows you to load in your own impulses for an an unlimited amount of neverb and amp possibilities. To give you an idea of the power of this app: There are literally hundreds of thousands of impulses freely available online and our app will load them all, given that it’s properly formatted in either .wav or .aif format. Say for example you have an electric piano sound that you want to run through a classic Fender™ AMP. You do a web search for “Fender AMP Impulses” and pick from the thousands of possibilities. You will literally spend hours upon hours freely downloading all of the available spaces, amps, reverbs, and/or delays to use within your favorite AUv3 DAW. The technology of convolving and deconvolving is a method of putting in a signal through an amp, reverb unit, delay unit, or space and with sophisticated mathematical interpolations techniques, you can create a very close replica of the actual source. Our IMPULSation is specifically designed for AMPs, reverbs, delays, and spaces of which our code is optimized to detect which is being used. The detection allows us to optimize the signal for better CPU and for optimal sound. As with all of our other apps, our goal is always simplicity with power. We give you all the important features needed for a great sound, without being too complex. The features are as follows: NEW UPDATED FEATURES: ▪ BlueTooth MiDI Capable ▪ iCloud Backup and Sharing of Presets ▪ Enhanced AUv3 Preset Resizing ▪ Expansion Pack Banners and Branding ▪ Metal support, Faster UI, Faster loading, and major CPU Updates ▪ Two Mode MIDI Program Change General Features: - AUv3 - AAX - 88 Factory Presets - The ability to load in your own impulses using the iOS files app (Works With External Drives via iPadOS) - MIDI Learn parameter **SPECIAL NOTE: Importing works by selecting a folder with .aif or .wav files in it and all of the files will be imported from that folder. App Controls: - Pre-Delay - Wet Controls with Range control for precise scaling - Dry Controls - Decay Controls - Waveform View - Stereo Widener that enhances pre-stereo signals - Master Output Includes Over 200 Impulses from very popular vintage reverb units: - LEX200 - LEX480X - RLND RE201 - RLND DEP3 Echo - EMT 244 - NBA Lush - ASR-10/DP4 - Exotic Places - Special FX ------- ATTENTION iFX Rack Users: 1.
