The Ultimate Chord Machine

Chordjam is an innovative MIDI plugin that builds chords and progression patterns through intuitive user-guided randomization.

Choose from a variety of scale types, Chord types, voicing parameters, rhythms and progressions or have its powerful sequencer conjure up unlimited progression patterns for you, based on any combination of settings, serving up unpredictable but always-musical variations.

Create unique and complex chord structures and infinitely evolving progressions.

Chordjam now supports MPE technology (MIDI Polyphonic Expression) to deliver polyphonic portamento/gliding chords which allows you to bend from any chord to any chord, both in real-time chord triggering or using the sequencer’s progression patterns.

Chordjam is the ultimate real-time compositional assistant for iPad. Designed to feed any Synth, Sampler and anything that accepts MIDI signal both software and hardware.

Featuring MIDI output support over WiFi or MIDI cable.
Chordjam also supports Ableton Link for tight sync between apps on the same network.

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

Mixes sharps and flats

I’m just now getting into it and didn’t want to give it a bad review. But did want to say that the key of C minor does not have a D# or G# in it, as this app seems to think. It has an Eb and an Ab. B# minor has a D# and a G# in it. I find this pretty annoying, kind of a speed bump, like misspelled words or bad grammar in prose. It can’t be a big deal to make the few flat keys and sharp keys display correctly. I wonder how confusing this could be for beginning musicians.

Hi, please toggle between relative & absolute mode(s) through the settings tab as explained in the manual.

Some good ideas but

Still haven’t gotten the hang of it. The workflow to find the chords is a bit weird in my opinion. mode. For example you can’t play a chord while it’s being edited. Meaning you can’t hear the changes you’re making unless you go out of the edit mode…!?

Most importantly, the standalone mode is completely broken as the midi out does not work as expected. It will only send midi notes when the sequencer is playing. Not when playing the pads manually. That means 1. You cannot select chords without their stock synth playing (which you cannot change) and 2. You cannot jam with chords once you’ve selected them. To send properly midi, you need to use the AUv mode in a host such as AUM…

Developer Response ,

Hello 👋 You can always preview your chord changes while you’re on edit mode. The standalone output should be working exactly as the AUv3 as they are identical, even when triggering the pads. Are there any changes on the standalone midi outputs via the settings tab?
