Delete a track while playing ? (live jam)

Hi there !
Still super happy with JJOS2XL on my MPC 1000, it's smoking.

One thing I didn't figured out, and I think it's not so crazy as a feature, is : how can you delete a track while playing ? (situation live jam)

I can do : record + erase + A bar
but this has many inconvienent :
- only delete 1 bar a time. So on a long pattern, you have to wait for the full pattern until it's deleted !
- it does not delete pitch changes, only the notes. Wich is a bigger problem.

I noticed that if you make some recording, you can not change sequence until you make stop.

Can someone tell me if I miss something or the reasons of such limitations ?
The only thing I really miss is a simple button "erase track" that works while playing.

I got JJOS 2XL 3.33

THanks for your help !

You would do better posting this in the JJ forum on this very website as this one is for Akai OS.

Not sure why you would need to erase a track but what's wrong with TRACK MUTE ?
You can do that on the fly while a sequence is playing.
Maybe you need to explain your problem a little better.

Ho yeah, my bad. I followed your advice, then :
