I use it to recall preset and it works well when i command the patch to load with manual triggering.

The problem is when I want to schedule the trigger with delays, the coll object is reading the precedent text list stored and then is changing the text inside.

I've seen on the forum it's due to the organisation between the delay and the coll object but i can't find any workaround...

I've a problem with the coll object.

I'm not exactly sure what you mean by "delay". Do you mean the lag time between telling the coll object to read a data file and the time it is "available"? Couple things to try:

1. put a "deferlow" after the trigger between the bang and the dump. This should ensure that the dump message gets to the coll after the file has been read, or

2. rather than having the trigger send the dump message to coll, use the bang coming out of the 3rd outlet of coll (bang on read) to go to dump.

It works well now when using the third outlet of coll to trigger the dump.

By delay I mean the delay object.
