The band in your hand - Create custom backing tracks instantly

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.

Incredible tool for composers!

Hard to believe that an app that has been around for so long is still so useful. As a songwriter working on a musical this is just what I needed.

The only disappointment for me was that the audio export is mono. It doesn’t look like this app is getting new feature updates, but I would love to see stereo export!

why no 444hz?

while i was pleased to see 432hz available, why no 444hz? it stops at 443hz? honestly i dont know why just about every single music apphas to make it so hard to tune to whatever frequency we want, it really makes the whole internet conspiracy theory about 440hz seem substantial when every single app makes it just about impossible to use anything else without lagging from pitch shifting etc. i really hope the chordbot developer can make 444hz available, that would be great and make me happy with it. besides the occasional crashing and losing my work, ireally dolike chordbot and think it is really great, but i do want to use 444hz and yes, 1hz is an audible difference to me and the 443hz sounds out of tune with my guitar tuned perfect 444hz. i recommend anyone trying 444hz tuning standard, it makes everything feel happy and enriching somehow, whereas both 440 and 432 leave me feeling depressed after a while. 432 feels natural and like nature but in a way, dull, while 440 sounds mechanical and like machinery more than human music, i find 444hz is just about right, not so far from 440 that you have to relearn how to sing yet just brighter enough to feel really nice and positive.

Amazing App! Needs a pro version

Great for creating song starters. Excellent if you need to quickly make songs for film, television, and or online content. Would love to see a pro version where you buy download more packs of different styles and user templates.
