GarageBand "Hard Rock" Guitar plucking instead of sustaining

I have a student in one of my music classes using the hard rock guitar MIDI instrument. When they select the instrument for their MIDI sound, the instrument will sustain while they hold down a key on the USB keyboard. After a few minutes the instrument will change from holding to plucking the note and note sustaining. They do not change any settings and I watched them to make sure it they didn't change anything by accident. They are on GarageBand version 10.1.3. It has happened for a few versions now so I am not sure if it is a bug or something else.

They are on OS X 10.10.4 and have a mid-2010 iMac with a 3.06 GHz i3 processor with 4 GB RAM.

Have you checked, if the students have the arpeggiator enabled? The controls are in the "Smart Controls" panel for the midi track in the upper right corner.

If the Rock Guitar is a Jam Pack instrument, the expression of the instrument may change depending on the note velocity.

For example, the Prog Rock Muted Guitar:

Prog Rock Muted: • Notes below E0 play slides, dives, and pick sound.

• Mod wheel combined with highest velocity plays trills.

It wasn't the arpeggiator. Unfortunately, I can only check when the student is in class because they have to log in. I did swap out the MIDI keyboard with one from an unused station and so far it is working. If it still works after tomorrow I am guessing it is something with the keyboard.
