I made this beat last week as a little experiment by sequencing the SP404 with my Roland MC307 groovebox. It's just a quick beat, but I thought I'd post since I rarely put anything up for you guys.
Yah bass and some synth sounds are from the 307. The other blippy synth sounds are from sega genesis. The piano is from some 80s b-flick I got on VHS.
I actually created the bass patch myself. The 307 has the ability to layer 4 sounds to make a synth patch. I just used two Super Sines and filtered it a bit.
