Experiencing difficulty and/or limitation when performing moderate to fast tempo 16th notes, 32nd notes, and triplets (1/4, 1/8)

for example:

staccato, spiccato, and scat style melodies which require multiple repeats of single notes within the riff or phrase.

Thanks for your time & consideration!
