Midibox SID v2 with one sound chip built into a datassette case.
All the original buttons are functional: Rec, Play, Rew, FFwd = MB buttons 1-5, Eject = menu.
Here's some Saga FM fun. Don't know if you call it 'chip'tune or 'fake bit', demo clip for a Saga FM VST.
The sweet thing about the VST is it can serve as a UI for the Littlescale GenMDMidi interface to produce the same sounds on actual HW :)
