ChordMaps2 is a music app for iPad which allows musicians, songwriters, music educators, and students to explore and improvise chord progressions, melody lines, and bass lines, in both major and minor keys, most of the time tapping with just one or two fingers. The most powerful feature of ChordMaps2 is that users can explore and play common chord progressions by touching chord locations on "Musical Maps." You can work with ChordMaps2 as a... Songwriter - to explore melody lines, bass lines, and chord progressions when you are away from your guitar or keyboard. Music Educator - to demonstrate principles of music theory, (including major and minor scales, diatonic and secondary chords, common chord progressions like IV-V-I, ii-V-I, I-vi-IV-V, I-V-vi-IV, etc.) You can also create spontaneous ear-training exercises, and explore melodic lines and chord progressions with students in an interactive environment. MIDI Musician - to tap out chord sequences and hear them played by one or more of the synth apps on your iPad, or you can send the MIDI information out through a MIDI interface to a computer running a digital audio workstation (DAW) like GarageBand or Logic Pro. How ChordMaps2 Works... ChordMaps2 is a MIDI controller. It works by being paired with a synthesizer app that generates sound. (Example synth apps include ThumbJam, SampleTank, bs-16i, iM1, and many more.) ChordMaps2 sends the MIDI signal; the synth app responds to the MIDI information and creates the audio. Video demonstrations of ChordMaps2 are found at the website. (Click the Developer Website link or visit Mugglinworks.com/ChordMaps2).

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
