i wanted to try if the size slider makes the same crazy things when i connect the lfo to it. and as i thought: yes. so the problem must be the jcom.parameter or the route object (i guess). So here is the latest version of my buggy module, if anybody has the time to have a look at it. i hope when this module is working i will have not so much problems with the other ones, otherwise it will take a long, long time to port all to jamoma.
