I got Voxatron thanks to Humble Bundle (despite Voxatron was available only on the $10 plan, i bought the base price which was 1$ and it also came with Voxatron by accident) and i thought about trying the designer, but i can't find a up to date youtube tutorial (many ones are made around to 2011 to 2013) and i cannot read the manual if i haven't followed a beginner tutorial.
