ChordFlow updated – new iOS MIDI chord sequencer app from Dmitry Klochkov gets improved MIDI out functions

Download from iTunes App StoreI did a round-up article a good while ago here on the Music App Blog that looked at the various ‘MIDI performance’ apps available for iOS. A couple of apps that have appeared since that article are ChordUp and Clawtar, both from developer Dmitry Klochkov. Both bring a slightly different take on the whole MIDI note creation process and I’m sure many iOS musicians could find a use for either app amongst their utility apps. Both are also available for pocket money prices.

Dmitry’s new app  – which as I mentioned recently was launched at the end of April – is Chordflow and is in the same sort of territory. ChordFlow is described as a chord sequencer with a built-in arpeggiator function. It allows you to construct multiple chord sequences (the app features a library of over 50 chord types) and the chord sequences themselves can then be placed into ‘sections’ that can then also be sequenced to give you a song-like structure.

Chordflow’s main screen… and showing the new option for duplicating a song section.

With the chord sequences defined, you can then construct a four-part note pattern within each section and that dynamically modifies itself to fit the current chord – this is sort of an arpeggiator but with a bit of a twist – and the MIDI notes generated can be played back via the internal (GM-style) sounds or sent out to another iOS music app or sequencer for recording. The note patterns can have up to 32 steps so you can build quite complex parts.

I’ve yet to do a detailed review of the app but it is universal, offers Ableton Link support, requires iOS8.0 or later and is a 30MB download. It is also modestly priced at just UK£6.99/US$6.99. All the key functions seem to work well and are easy to follow and I could easily imagine this being used in an experimental way as a song-writing/compositional tool….   create a chord sequence, draw in some note patterns, feed the notes out you your favourite synth app and see what inspires….

Each Chordlfow track can now be sent to a different MIDI destination…..

Anyway, Chordflow moved to v.1.1.1 over the weekend. The update adds some very useful new features but the highlight is that each of the four tracks/lanes can now be assigned to different MIDI out destinations. You can, therefore, use Chordflow to drive more than one other synth for even more interesting sound options. I gave this a spin with four AU-based synths hosted within AUM and the MIDI routing required proved very straightforward.

… as shown here with all four tracks going to different channel number in AUM….

Another addition is the option to duplicate a ‘song’ section. When you tap the Edit button, if you then tap the ‘delete’ (red minus) button, rathe than just deleting the section (which is what you might expect), you now get the option to either delete or to duplicate. OK, you might have to be a bit careful with your finger tapping, but it works very well.

… and driving four different AU-based synths :-)

In addition to these new features, the update also brings a few refinements and bug fixes just to bring a smoother user experience….  always welcome obviously. When I get a chance to dig deeper, I’ll post a more detailed review….  but, in the meantime, check out the demo videos below and then hit the download button to find out more via the App Store.

    1. Wow I somehow missed this one.

      What a lovely app for sketching out ideas and finding nice things to play with.

      Worth every penny
