Yes, I spent yesterday trying to sculpt the lowest dynamic layer in the JB Violin. It was quite resistant to the performance I wanted and would have been a relatively simple matter to coax out of one of the SF violins. I’m still learning the JB so maybe I’m missing something but I suspect the behavior I got is what the instrument is designed to deliver. Don’t get me wrong, I very much like the JB Violin and it is far more versatile than I had feared. But it is nevertheless optimized for certain things and those things appear to come at the cost of other things.
Hmmm, what Control Preset did you use? If you want *just* the lowest dynamic, I would highly suggest using something different than the default preset, which triggers legato dynamics via MIDI velocity. Try one of the "Pro Controller" presets, which allows you to set dynamics via MIDI CC. That way you can consistently trigger *just* the lowest dynamic. IMO that set of samples is super beautiful. Gentle but full.
