CubuSynth Engine V2 - Build Guide SMD-PCB V1.1 Jul 2023 STEP 8 Front Panel When everything is in place, take the front panel and put it on top, so all controls go into each corresponding hole of the panel. Since it is over 40 parts that need to fit, "wiggle" the front panel into place and make sure everything fits well.
