Anyone experienced the following?

Create sequence, record kick, hat and snares on tracks 1-3 using a drum program in memory.
Track 4 set as a MIDI track, set MIDI 1A, record a bass line using external sound module, with that module hooked up to INPUT THRU
SOLO track 4, go to REC SAMPLE , input MAIN OUT.
Arm RECORD and press PLAY START.

At this point, I should only hear the bass line SOLO'd on track 4. Instead I get the bass and random drum samples. So, I check track 4 - it's set to Type:MIDI, MIDI:01A, Program:OFF. I check STEP EDIT. Nothing unusual.

I physically turn off all other tracks and SOLO track 4 again. Still I hear random drums.

Finally I delete all programs from memory. Now it stops.

WTF?

BTW, a re-boot did not solve this, although it only seems to affect 2 sequences in a 20 sequence project file.
