...and I'm really enjoying it! There are some things about itthat seem a little wonky. But I got it basically working good enough to put together some quick acoustic guitar tracks.

All I can see that it can make in the strum mode are Maj, Maj7, min and min7. I would like to introduce some other chords structures such as sus2, sus4, dim, etc. Anyone know how or if possible?

If you set play mode to "guitar" you can hold the chords with one hand (right or left) and strum it with the other hand. If you hold a sus2 or 4, dim, it will respond to it, have you tried ?

Albert - No, I haven't. I knew it would do it in "Guitar" but was hoping I could get the same functionality in "Loop' mode.

Thanks for your input!

I had a quick test at the Loop mode and found that the style only gives you strum patterns. You can hold any chord and the voicing will respond to it.
