How ChordMaps2 Works

ChordMaps2 works by being paired with one of your other music apps. In other words, it acts as a front end, or playing surface, for another app.

The other app plays the sound; ChordMaps2 tells the app which notes to play.

The video above demonstrates ChordMaps2 sending note information to apps like SampleTank, ThumbJam, Nave, Launchkey, or PiteaMini.


As a songwriter, you can use ChordMaps2 as a go-anywhere musical sketch pad for exploring musical ideas. You can explore common chord progressions like I-IV-V-I, or I-V-vi-IV, or I-vi-IV-V, as well as more complicated progressions that include secondary chords, and you can transpose these progressions into any key.

With ChordMaps2, you can explore and improvise melody lines, bass lines, and chord sequences when you don't have your keyboard or guitar with you.

If you are wondering about the cost...

Sometimes it's helpful to know how much a project will cost in advance.

If you have an iPad (running iOS 8.0 or later), getting started with one sound-generating app, plus ChordMaps2, currently costs about 20 dollars USD.

Here's the breakdown. The app we recommend for playing sounds, ThumbJam, was 8.99 USD at the time this page was made. ChordMaps2 is 9.99 USD. This adds up to 18.98 USD.

Some sound-generating apps (like SampleTank) have free versions, which would allow you to purchase only the ChordMaps2 app for 9.99 USD.

If you already have a sound-generating app (like ThumbJam, SampleTank, iM1, Nave, bs-16i...), you can add ChordMaps2 for 9.99 USD.

Bands, Worship Teams

As a band or worship team member, there are times when it would be useful to add a pad sound behind certain songs, or maybe brass lines and hits. If the song contains basic chords, extra instruments like these can be played easily using ChordMaps2.

With ChordMaps2, your band or worship team can add extra sounds (like pads or brass) to songs that could use some extra instrumentation.

Music Educators, Music Theory Students,

Music Technology Classes

ChordMaps2 allows teachers and students to explore melodic ideas, bass lines, and chord progressions simply by touching locations on the screen. This provides for real time ear training, and offers beginning students the chance to explore chord progressions they would not yet be able to play on a traditional instrument.

With ChordMaps2, you can demonstrate chord progressions in the classroom, and give students the opportunity to explore and experience playing chord progressions in a variety of styles and keys.

Composers, Midi Musicians, Home Studios

ChordMaps2 can send the MIDI insructions out of the iPad (through an iOS MIDI interface) to play and record sounds in a computer's digital audio workstation (DAW). In this case, the iPad screen running ChordMaps2 becomes an alternate MIDI controller, with locations for melodic lines, bass lines, and chord progressions.

With ChordMaps2, you can use the iPad as a MIDI controller and send MIDI signals to a computer DAW.
