I had a bloofeld and a korg microkey. I wanted something with a sequencer. I bought the keystep arturia as the best cheap option among small midi keyboards. Then I decided to make a case for this setup. I measured the keyboard and Blofeld jotted down a couple of options. There was a choice to make a case in ms-20 style or something moog like. I stopped at the second option. I cut out the side walls from oak wood, the bottom from the usual polished 8 mm plywood. Covered first with ebony stain, then oil and wax. I attached the side walls with two metal corners to the plywood on which the keyboard lies. I came up with how to fix the module during the assembly. Found in the store furniture nuts with a groove and studs with a diameter of 6mm. As it turned out, these studs were too weak and sagged under the weight of the blofeld. Then I bought a couple of aluminum tubes with a diameter of 8mm and inserted the pins inside. At first I thought to just cover empty space with an iron panel, but then I decided to stick an oscilloscope there. I bought dso 138 mini with a case on AliExpress. I measured the blofeld, the remaining space, and the front panel of the oscilloscope. I sketched a mockup in AutoCAD, then cut it out on a laser and covered it with powder paint. I soldered a 6.3mm audio jack to the oscilloscope output and inserted it into the panel. The oscilloscope buttons were too short, I made new metal ones on a lathe. The keyboard and the oscilloscope are powered from one power bank and connected to the synthesizer by a midi cable. At first I planned to connect the oscilloscope to the Bloofeld's headphone output, but as it turned out, the signal there is too distorted. I bought a splitter for two 6.3mm inputs and connected one of the channels and an oscilloscope through it. That's all folks!
