Here are some of the most common Chordbot related questions, problems, answers and solutions. Please contact [email protected] if you have other questions or if the described solutions don't work.

Installing Chordbot on a new device without buying a new copy

As long as you are using the same app store and user account as when you originally bought Chordbot you can redownload the app again without extra charge, even on multiple devices.

Apple Devices

  • First try to install Chordbot from the Purchased Apps tab
  • If Chordbot doesn’t show up on this list but you are sure that you are using the same user account as when you originally bought it (important!) you can just push the buy button again.
  • After confirming the purchase you will get a notification that you have already payed and the app will install without any extra charge.
  • If something goes horribly wrong and you are still double-charged: Send both the old and the new receipt to [email protected] and we’ll refund you through PayPal.

Switching platforms (iOS <=> Android)

Unfortunately it isn’t currently possible to transfer licenses between different app stores so you will have to buy a new copy for the new platform. Cross-platform licenses might be available in future versions of Chordbot but there is no ETA on this.

What do the chord colors mean?

The color of the chord indicates how well the chord fits in to the currently selected key.

  • Green: All chord tones belong to the current key.
  • Yellow: All chord tones except one belong to the current key.
  • Red: Two or more chord tones are outside the current key.

Green chords are guaranteed to sound good together (at least in a traditional sense). Yellow chords could work in certain situations while red chords are more likely to clash with the green and yellow chords. These are not absolute laws, so depending on what kind of a sound you are lookig for a red chord might be perfect for your song.

Selecting an unusual mode and using diatonic (green) chords can be a good way to discover interesting and original chord progressions.

Sharing songs with other Chordbot users

Chordbot song files (in JSON-format) can be shared between Chordbot users by sending them through any standard file sharing app (E-mail apps, iCloud Files, Google Drive, Dropbox, OneDrive, etc.)

These files can also be used as backups of individual songs.

Wrong instruments in exported MIDI-files

By default Chordbot will add Program Change messages to the exported MIDI-files that instruct the playback synthesizer what instrument samples to use. The mapping of these instruments correspond to the venerable but ancient General MIDI standard which is seldom used in modern softsynths.

This will typically lead to your softsynth switching to an unwanted patch during playback. In order to avoid this you can disable the Export GM instrument map option under Menu > Settings.

Importing songs into Chordbot

  • Locate the file you want to import, in the app you received it in (E-mail, Dropbox, iCloud, Google Drive, etc).
  • Click the file and you should be given a choice of apps that are capable of opening the file.
  • Choose Chordbot from this list.
  • Chordbot will open and ask you if you want to import the file.
  • After you confirm the import the file will be available from the menu Open

Many file sharing apps will first preview JSON-files as plain text. If this happens, lock for an Open in button/icon, click it and choose to open the file in Chordbot.

Note: Only song files in JSON-format ('MySong.json') can be imported back into Chordbot. It is not possible to import MIDI- or WAV-files.

Missing presets from Chordbot 1.X

In Chordbot 2.0 all the old styles from Chordbot 1.25 were split into individual tracks that can be combined and mixed independently. Most of the old styles are still available as presets, but some of the simpler ones that mostly consisted of a single instrument (Balladica, Pluckocaster, Plaino, etc.) and some others are now only available as individual instrument tracks.

If you're missing a particular style from the old version you can use this list to find out what tracks you need to combine to recreate them.

Planned features

Here's an incomplete, undetailed and unordered list of planned features:

  • Style/pattern editor
  • Downloadable song libraries
  • Downloadable sound libraries
  • Intros, outros and fill-ins
  • Next chord recommendation algorithm
  • Support for 1/8 note durations
  • Web and desktop versions
  • Live MIDI Output

No ETA's can be given on any of these. Chordbot is currently a one-man part-time project so development will take some time, but will on the other hand also continue indefinitely.

Style requests

If there is a style or instrument pattern that you would like to see included in future updates the best thing you could do is to send in a short example of that style as a MIDI-file.

A few bars are enough, no intros or endings required. Record it as it would sound in the middle of a Chordbot track. The patterns have to be repeatable and work with any four note chord. Use only chord notes, no embellishments or ornamentations. Drum patterns can use most sounds in the General MIDI specification excluding helicopter noises, dog barks and similar abominations.
