MidiBass 303 - the ultimate 303 midi retrofit

Someone asked how to copy pattern on a Roland TB303. The general recommendation was unfortunately older than old school - pen and paper. There is a way you can step through the pattern you want and copy the new pattern referring to it, but most thought pen and paper were easier and more reliable for reference. However punkdISCO pointed out Colin Fraser's MidiBass 303. Title link takes you to more including a sample.



"The problem is that if you want to keep hold of your favorite patterns, but your memory is full and you want to create some more, it can be tricky and time consuming to accurately transcribe your patterns for re-entry at a later date...

To solve these problems, I have developed the MidiBass 303 midi interface.
This interface provides both midi output from the 303 internal sequencer, and midi input to drive the 303 synth section, along with midi clock in and out."
