this is an interesting line of discussion coming out of this. thats nice : ) again i am very grateful to frank for pointing out what i missed. i will take your comments serious. triggering was indeed something i was not very aware of. now i see it is of essence. obviously..one has to be aware of the flow of things in things if one hopes for certain results.. this makes sense to me.. i looked at the patch and it was well explained. so actually i am amazed by the way you explain. thanks frank !
please dont think im ignorant towards the xy_to_amp because i have not answered to it. im just taking it step by step. once i understand what i did and doing i can understand other approaches as well : )
best
