Debateable. Depends on the workflow. I sold my 555 because I didn’t feel I needed it anymore. However my work flow was using a mpc and sp404 for a long time and I missed bouncing stuff back and forth. Fx are the similar or better in some cases, but overall the live is a way more robust machine than any Roland sp.
If your a all in one box guy, definitly yes.
Is you enjoy using multiple boxes not so much. There are a few features I miss from the sp lineup. The 404s are getting cheap enough that saving an extra few weeks I believe to be worth it to have the two.
