Purchase, installation and authorisation are all painless, but potential users should be aware of two technical elements of the current specification. The VST versions may work with other hosts, but such combinations are not currently official. Industry Of Captains Captain Chords is the heart of the system. You can then use various tools to develop chord sequences for the different sections of your song. The last four of these allow you to create four different chord sequences which can be in different keys if you like ; the controls running down the left edge of the user interface can all be configured individually for each of the four song section tabs, and apply to the whole sequence within the selected tab. Strum and Swing can also add some nice performance details. Do note, however, that all these settings apply across the whole song section, not just the currently selected chord within the sequence. The Rhythms and as shown here Timing presets make it easy to customise your basic chord sequence.
