I can get my Ti 2 Desktop to freeze pretty easily if I do the following:
- go to preset/patch (e.g. ROM-A 22 DampPtchBC, a Mono Bass, but "works" with any patch)
- press SHIFT-AUDITION for several seconds to hold the note
- shift the octave
- change to a different patch (the note of the first patch is still ringing)
- audition the patch
- change back to the first patch
- press SHIFT-AUDITION --> the note will not stop anymore
- press SHIFT-AUDTION for several seconds --> a second note is hanging
- press SHIFT-AUDTION a couple of times, throw in a couple of octave shifts for good measure
---> Virus will suddenly stop all other sounds and put out at full volume what sound like a narrow pulse wave at the pitch of E3, no controls work anymore, device must be shut down.
I wasn't able to force that condition on TI OS 5.0.8.
