MIDI Guitar 2.2.1 & Best instruments and plugins of 2020

I’m always impressed with your videos and playing. Thanks for the inspiration. MIDI Guitar 2 is great but can’t seem to get great results with piano samples. I’m wondering if I’m missing something in the setting of velocity, volume, attack, release, etc. Single lines aren’t a problem, just chords. I mostly play fingerstyle and know a clean technique is important. Any suggestions are much appreciated. Thanks
