With regards to improving the arranger functions:

I would like to see the better features of the current keyboard arrangers duplicated (e.g. dynamic arranger, etc.) BTW, I really like the way Synchro Stop is done in Ketron keyboards - a quick press on the left-hand keys will cause it to stop. This is better than stopping it whenever the left hand keys are lifted. You might consider making this type of operation a configurable option.

The symbolic programming sounds interesting; however, my concern is that it should be useable by the performing players (easy to cotrol). I am not familiar with Karma functions, but Yamaha has control over "Grooves and Dynamics". It would be nice to have real-time control over these, so that one could "funk-up" a style in mid-play.

REgards,
