Synfire Constantly Creates Extra Instruments

Same here: (https://users.cognitone.com/comment/24573#comment-24573)

Yeah, I've known about this for a while as I often work with snippets. It's annoying, it creates a new channel when dropping a new phrase into a snippet that uses a different instrument from the previously established snippet instrument whether you ask it to use the same instrument or to create a mixed group. Not the worst behavior but it can result in a huge track count and having to be very careful when you need to delete many tracks.

Yes, ads also a unwanted extra instrument  

When you drop a phrase from a library or another arrangement, carefully check what the wizard or other dialogs are suggesting or asking you. Synfire doesn't silently add an instrument unless you drop a phrase on the empty slack area or between existing tracks.

A unwanted Synh Strings 1 instrument is added when inserting other instruments plug in 

Yes, it definitely creates new instruments spontaneously. See gif: Suddenly an instrument Synth Strings 1 appears for no reason. It looks like it has something to do with the save command. At least for me it usually happens after saving.

Thanks for the gif. That's weird. Must be a regression that slipped in as a side effect of some other change. Will check that.

If you don't find the root cause, just sell it as a new festure. Suggestion for the changelog:

Arrangement: New instruments are added automatically if KIM recognize that your arrangement is just too boring and needs more instruments :)

Yes, that's real musical AI : do this and do that advice to improve your arrangement..future music :-)
Then focus only on orchestral music and modern pop variations of it.
Musical AI is still in its infancy it seems.

juergen, you should apply for the position as product manager at Cognitone ;-)
