This is what I mean. Nothing like this exists on the market AFAIK. BFD running on a tiny format, from an SSD. 7" screen. Super portable TINY BFD.
It wont cope with effects (i havent explored TINY BFD much since I got it working tbh) I dont think, but purely streaming audio data from a drive, being played via MIDI, it can do that it seems.
And consider the PC power BFD1 was running on, 20 years ago or so… We really should be able to run BFD on a tiny PC with no issues. Suddenly, a whole portable world of real drum sounds from a tiny drum machine opens up.
