Thanks for sharing, Hayden! I have become a R275 convert based on this thread, have spent some time trying out and learning about different settings, and so was very interested to see this post.
A question and a couple points of clarification that may be useful for others.
Q: Hayden, can you take one more screenshot that shows your velocity curve? From the main screen (your first image), click the icon on the upper right between the tuning fork and gearwheel (looks like a set of stairs). That will open up the velocity control window, and I would be interested to know if your setup uses the default velocity (0,0 to 127,127 linear) or something else?
For TomLC and others who may be interested, the sound depends very much on listening conditions, room, speakers, headphones, etc. Having said that, I think the best way to experiment with different sound qualities is to mix the microphone positions. Default is 100% Close, the way Hayden has it set up. But adding in 5% - 50% of Player, Side, and/or Room will have a big effect. (In my hands, Room has too much reverb; also, my computer, a powerful MacBook Pro, can only handle one additional microphone sample set, and I like the quality that comes from 100% Close + ~25% Player or Side).
Also, in Hayden’s settings, I’m surprised to see Dynamics turned down to 43% (default is 96%). This limits the dynamic response of output volume; in other words, at 96%, a soft touch sounds soft and a heavy touch sounds loud, but at 43%, touch won’t have nearly as much effect and volume will be moderate the whole time. (This is similar to the compression that goes on in Logic or any DAW).
Finally, the biggest impact on sound for me (in addition to the microphone mix) is the velocity curve. I prefer a curve that is pulled down a little bit, but it will be different for everyone’s mix of controller, touch, listening conditions, and personal taste). A good way to learn about and experiment with different velocity curves is to open the panel (as above), then start playing, and watch the screen. It will show both input velocity (what your hands and midi controller are doing) and output velocity (what the program is sending to the D/A card. Range of velocity is 1 - 127, and most people will want to be able to easily go from ~25 to ~ 100 in output velocity. (You can adjust your velocity curve with the knob to achieve that range).
Sorry for going on so long but I thought I might save others some time.
