Anyone using their retro machines to make music or for live use? I experimented with making live Acid music with a C64, using Mssiah, and a 303, etc. The timing of the 303 clone wanders sync too much

Anyone using their retro machines to make music or for live use? I experimented with making live Acid music with a C64, using Mssiah, and a 303, etc. The timing of the 303 clone wanders sync too much as is but maybe adding a better midi clock like a modern drum machine to help keep it all synced.

Thought, opinions?
