I got their XLN RC-20 presets.

Ok, let me re-phrase what I said. With MIDI-learn MANY of the limitations can be worked around.

Specifically, I was thinking of how Indiginus limits trills and grace notes to only notes in the chosen scale. But you can MIDI-learn the chosen scale and adjust it on the fly. Now you can get any trill and grace note you want. Things like that.

True, but with MIDI-learn most of the limitations can be worked around. These are extremely useful libraries that sound very, very good.

My go-to acoustic guitar/banjo libraries. You may need to EQ the highs out a little as they come a little to hyped for my tastes.
