Elektron Musical Instruments

My Machinedrum arrived Friday and I'm having great fun with it. (It's 
got one knob that's a little sticky in one spot, but I'm hoping that's 
something that will clear up with a little use.)

Is there  a way to duplicate a pattern while the machine is playing? 
Yes, I can copy, switch patterns, and paste, but that potentially plays 
the second pattern very briefly. What I want to do is duplicate the 
pattern so that I can tweak on it and then jump back to the original 
pattern without any apparent breaks in the music.

Thanks.
Mark
