I just upgraded to v26 on my Win 10 system and find "Electric Pick Bass" unusable as the amount of vibrato added in the soundfont totally unrealistic. Adding an expression with channel pressure set to zero does not remedy the problem. Now I fear other instruments sounds in the new version will also be afflicted. Please take advantage of the many seasoned musicians at the forum that would gladly give you advice about how his or her instrument should sound, without any charge. But then, all you need to do is listen to professionally recorded bands and orchestras. Sigh!
