The step sequencer was left out back when the Evolution engine updated to Kontakt 4 in favor of a strumming recording system. The strumming recording system relies on your DAW's own sequencer for pattern creation. These patterns are then transferred into Evolution, and are saved as pattern files that can be recalled whenever you need them.
The nice part about the system is that the patterns can be as many measures long as you need. You can also use complex rhythms, and work in the familiar environment of your DAW's sequencer rather than a limited built-in sequencer.
The downside is that there's the extra step when creating patterns of transferring the patterns into Evolution. Also, it's not as convenient for creating quick, simple strumming patterns as a built-in simple pattern editor would be.
Right now I'm planning out the next update for the Evolution guitar engine, which will make several major updates. A lot of the changes and additions are based on suggestions I've received over the time that the Evolution guitars have been available. Here's an example of some of the things I want to do:
- Upgrade the tone preset system to be like Evolution Electric Bass - Rick, so that you can quickly scroll through factory presets (with their names being shown on the interface) as well as having the usual option of loading and saving external preset files. You can see this system here:

For better MIDI integration (e.g. the ability to drag MIDI sequences out of Evolution into your DAW), I would need to use Kontakt 5. I'm still undecided on that aspect, since I always like supporting Kontakt 4 when possible.
- Articulation mapping system like what's in EEB Rick. It's easy and intuitive to use, and allows you to get a better idea of the entire mapping from looking at the setup:

This factor won't affect the end user as much, but will make it much easier for me to release additional guitars faster, not to mention being a flexible system for adding guitars with 7+ strings, different numbers of frets, different assortments of articulations, and so forth.
