Chordbot lets you create and play chord progressions in different styles easily. Just add chords, select instrument tracks and hit play.

Experiment with complex chord progressions without having to master an instrument or music theory first. Great for songwriting experiments or to create your own backing tracks for instrument practice. Easily create arrangements and mixes by selecting from hundreds of piano, guitar, synth, bass and drum tracks.

This is the full version of Chordbot with all features enabled. There is also a free evaluation version (Chordbot Lite) with disabled save/export features that you could/should try before buying the paid version.

Features:

* 60+ chord types
Including classics like AugAdd2 and Min7(#11), in all inversions.

Individually mixable dynamic instrument tracks that can be combined to form unique comping styles.

Refine your compositions in a DAW/MIDI sequencer or play along with a virtual instrument

* Song-O-Matic
Automatic song generator with pop, jazz and experimental profiles.

Pros and cons of Chordbot app for iPhone and iPad

Chordbot app good for

My main backingtrack tool. Simply awesome. Just 2 suggestions : tempo change into each chord, and another app to generate our own track templates for drums, synths etc. , allowing sharing. Very good job.
Exactly what I was looking for! It would be nice to re-arrange the Sections; put Section 4 before Section 2, for example (without copy-paste)
Im writing simple songs and this App does an incredibly good job in helping me the right harmonies. Nice sounds as well as a GarageBand export!
Intuitive and really smart. First choice. Would be perfect if you could change the style between sections.
A very nice app for quick progressions. Its even audiobus compatible which is great. Now pls add audiocopy and its perfect. :)
I downloaded Chordbot last night and in a matter of 15 minutes had a song laid out ready to sing/play along. Simplest app Ive had the privilege of using. Very intuitive interface. Good job guys! Im hoping to see a few additional feature down the road, like annotation (intro, verse, chorus), ability to copy/paste based on those song segments and ability to import comping styles or simply more comping styles added. Good job again on a great app. Great for jamming, improv and even live performance.

Some bad moments

The long-awaited new version crashes while editing, crashes while playing. It contains not only all old problems, but also the new UI is way less convenient for me. I would appreciate if you kept the app simple and reliable. Waiting for bug fixes!
I remember downloading this app several months and then deleting. I saw some good reviews of the latest version. I picked it up again, and yep, its headed in the perfect direction. 4 stars because there are some crashes and because there seems to be no effective auto-save I end up losing work. More patterns, comps for strings, some fill patterns for each comp, support for more rhythm patterns, more comps for non 4/4 times will make it even better. Whole heartedly recommend for any composer, arranger, performer figuring out chords for any number etc. Way to go mate!
This app is precisely what I went looking for, only better. If youre a songwriter, it is perfect for sketching out & experimenting with chord progressions. I had tried other more fully-featured sequencing apps but they were all just too complicated & time-consuming for the kind of "sketching" I wanted to do. Chordbot nailed it in terms of intuitive interface, fast, smooth performance, more than enough stylistic options (in the paid version) to help you visualize the song you have in mind to create. Even the free Lite version is excellent and completely usable as-is. I was so grateful for having found it that I wanted to buy the full version in part just to thank and reward the developer. The additional functions in the paid version are well worth the price. Unlike some of the other reviews, I personally would not want to see more features crammed in. As-is, it works perfectly well as a songwriters companion (or as a backup band for improvising over) and Id hate to see it get bogged down and more complicated.
The app was great when it worked, but it became completely nonfunctional after the latest upgrade. The play function stopped working for me, making the app unusable.
This is something I have been waiting for a long time to find! Thank you so much for this!
The only reason I am giving it 4 stars is because of the the lack of undo button. A few times Ive accidentally deleted a chord.
