Hola mi gente!
For some reason, when I play D#, F, G#, A# or C my Shruthi will
only trigger the previous note that I had just played.
For example, if I play A and then play C, C will retrigger A instead
of playing C. And then if I play D#, F, G#, or A#, they will all
trigger A as well.
It seems that only the midi notes not mentioned above will work right.
