Building patterns in a live situation

Is there a possible way to build new patterns but still have an other pattern playing?

I do believe the answer to be no, but it would be super if i wasn’t.
The only way i can imagine at the moment is either to have two OTs (or another sequencer/sampler would probably suffice) or to mute some tracks, rebuild, unmute/volume/effects, moving on.

The reason for this is to be able to start off of a partially built or empty project with the possibility to build as it goes on.

not sure exactly what you intend. can’t you use transition tricks to get you where you want to go ?

If I follow you, you’d like to be able to keep the current pattern playing, while being able to switch focus to a new pattern to program it on the fly?

I’m basically wondering if there is a way to do this without connecting to any other gear.

…can’t you just resample your first pattern or elements of it and then use it in one track of your new empty pattern ?
