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 the user can explore and play common chord progressions by touching chord locations on one of the "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, which are then 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, Nave, GarageBand by way of MidiBridge, iM1, Launchkey, SynthMaster and many more.) ChordMaps2 sends the MIDI signals: the synth app responds to the MIDI information and creates the audio signals.

ChordMaps2 allows you to explore, play, or improvise interesting musical phrases and progressions on the iPad, in both major and minor keys. The MIDI information sent out can be played on a variety of synthesizer apps, or, with an iOS midi interface, sent to software or hardware synths.

There are video and audio demonstrations at the ChordMaps2 website (click the Developer Website link in the left column or visit mugglinworks.com/ChordMaps2). The video shows the kinds of musical phrases that can be played with ChordMaps2.

Wonderful, if a little overcrowded


I've enjoyed this app for years. When the new OS started giving warnings, I was worried the app would get updated. While I preferred the simpler interface, everything is all on one page now, but it also means using a stylus to press the correct sound. All things considered, I extremely pleased with this app. I even used it with KORG Gadget with no trouble.

Does this app work at all?


The fairly incoherent documentation seems to indicate this app will work with Korg Gadget, but there's no way to make Gadget play in the background so you can play chords in chordmaps2. Seems it only works with thumbjam which I'm not going to buy just to find out if this thing does anything at all. Let me know when this app works with audiobus or any other iOS MIDI standard.

Developer Response

The Korg Gadget app has a switch that turns Background Audio on, but the switch isn't found in the app--it's over in Settings. When you open Settings and scroll down to the list of apps on the iPad, then touch "Gadget," several preference options appear. Background Audio is one of the options. When you turn it on, ChordMaps2 can be used to send midi information to Gadget.

pretty cool but needs AB support etc
