I use Beatstep Pro as my master clock sending din/sync to Drumbrute which I have set to auto sync so I don't have to change any settings when I start up. I would like Minibrute 2S to start up with ext clk as default or have a similar auto sync option so if I power down and back on again everything is ready to go without having to change any settings when playing live. I have no problem splitting the stereo out sync with a cheap headphone splitter lead so that it can go to both machines.
