Thx for the answer No codebox used Here is the patch The 4 history ops are isolated on the right in the main GEN patcher

Dont know if you can make smthg out of it, it's based on an old DSF synthesis algo and i got a little carried away with it But i got it to work quite well yesterday and today it wouldn't work anymore

Regards

Thx again for helping You are correct about hat ad variable thing but iit was just a typo and nothing to do with the history ops, so thats not where the problem lies I ll try to clean it up and report back if i find something

@ raja Re-up this thread cause i've been checking the patch in your reply A few things were misconnected but otherwise it works as expected, seems you've nailed the problem, so thk you very much ! :-) Just in case, i've attached a "cleaned-up" version to this post

So it clearly had to do with the multiple send - receive around gen subpatches... could this be considered a bug or is it a normal feature of the history op ? I like to use all of this stuff to keep complex patches as clean as possible, so being limited by this feels a bit annoying to me

Well I'm nowhere near a professional programmer so i have no clue how a compiler works but what you say makes sense. Like an infinite loop happening within the 1 sample inner workings of GEN I guess you can't call that a bug, indeed, it's just that nothing prevents you from making it occur when patching stuff without using a codebox Thx again Regards
