# Roland TB-303 with MIDI Mod
”
Not only does this particular unit work perfectly, but it has even been modified so that you can control several parameters through a midi controller! That means you are no longer a slave to the internal step sequencer or external drum machine. Either use it as was like a standard 303 or connect a midi-CV converter (such as a Kenton) and run it through your computer sequencing program (Logic etc.) and you can play the 303 freely with your full sized keyboard like it was any other midi keyboard. Record midi notes and even accent, filter, and slide information. Play it back through your sequencer and listen to your box get down! This unit has some cosmetic scratches and discoloration, but has all original knobs and sounds perfect!” Link
