Shreddage IIx - articulation change problem

[caioh]

Greetings,

I'm using the default configuration for the articulations and I have a problem changing from tremolo to mutes.
The midi starts with mutes and then continues with tremolos but when I change the articulation to mutes after the tremolos it continues playing tremolos.
I have to change a random keyswitch and then reset to the default to make it working properly again, but the problem backs when I trigger a tremolo articulation.
This does not happen with changes between mutes and sustains.

The problem appeared today, I have used it for a month without any problems...

My daw is Reaper v4.731

Thank you in advance for any help.

Do you have a midi file available to look at?
