ultra303 [TB-303 CPU replacement project]

The title says it all… well, no, it doesn’t really, does it?

The ultra303 is an impressive mod for the Bass Line that not only completely replaces the CPU with a new one to add totally new features, but also has a very cool LCD display which looks at once out of place and comfortable on the front panel. The original sound-making part is still used and the new system completely emulates the old one. But it adds MIDI, realtime PC-based editing, a SID emulator to add new sounds, velocity and a whole load of other stuff.

Check it out.
