Thanks for the link. unfortunately it adds lots of money to post to europe. The mk1 isnt the best thing anyway and before spending 70 euro I probably use the ipad with modstep and elastic drums. My PSU is working but it is burried behind lots of furniture and other cables in my studio setup. wanted to have a small live setup and need the machinedrum mainly for sequencing the minitaur (as cv gate sucks from the a4) but I suppose the ipad can handle this.
Maybe they will release an octatrack 2 at one point - till then I am fine I guess. Would be nice to have a second psu but not for that money… .
