Isnt that still a pretty cool pattern command to have?
Being able to stop all sound , including echo, delay and reverb?
"Stop all hanging VSTi's and sample voices".
It´d be a pretty cool effect.
I notice sometimes when i press that button playing the music. Makes for a nice break before the next part. (stops all, some single instrument comes in briefly, then the rest. )
And if you could do this also for a single channel. Then you could use very heavy reverb and completely stop it right after or where you want. (or something like that.)
