Simply Amazing

Writers Block? Gone! Best jazz improvisationist in the world? Absol- ok, not quite. I set it up on AUM with Module Pro. Set my midi keyboard to Module Pro. Left hand hits Chordjam which needs only one finger to generate beautiful, complex, lyrical progressions while my right hand is having the best time of its life (better than even that)!
Seriously, I’ve been looking for a tool like this and I credit Sound Test Room for bringing it to my attention. Watch a quick tutorial and you’ll be wondering how you could have been writing music without this.
The chords use up to five voices which covers an immense range from simple to very complex but each chord is always musical

I’ve been using Chord Jam all week. It is brilliant. My Korg Nano-Key Studio has been transformed as a songwriting tool. The timing and velocity controls give such a human feel especially to orchestral sounds. Thanks.

Flawed Concept

The interaction between the scale and chord type makes no sense. The app makes it impossible to produce some basic chords, and user chords are not supported. For triad people, it’s a clever and useful app. For jazz and modern composition it imposes some irritating limits on your chord options. The structure for choosing chords is not likely to be improved without a major rethink of the core concept. UPDATE: yes, I watched the tutorial vids and I fully stand by my original review.
