Ok, I've checked some options.
1) When operating the knobs manually withthat patch, the sound changed.
2) Automation failed as described - I've meanwhile turned off "write automation data", since drawing lines in the automation lane works independently from that checkbox.
3) Manually operating the knobs after that attempt with the patch TriLead1 in bank 8192 fails.
4) changing the patch to bank 8192, to MG Saw, the sound changes with the automation lanes. This looks as if the patch I originally wanted does not react anymore to automation, while othes still do.
5) in Bank 8320, there is "TriLead 2", which also does not react to the turning knobs. Problem: I do not seem to find any other patch sounding like a simple triangular wave form which could be changed by filtering. Will I have to kick out the Roland and change to PSYN II, which I actually need for another voice (and channel)?
Thanks for following up.

One hour later: No, PSYN II does not help: The automation lanes do not affect this instrument at all. Or do I have to create new lanes?
