I'd like to create a midi instrument with a human voice of fixed-do solfege in Logic Pro X, for example, whenever I hit a C on the midi controller, I'd like it to make a "do" sound. How can I do this?

  • Did you ever create or find such an instrument? If so could you share?

You have at least two options:

  1. Find a VST/AU instrument that includes those sounds. There are plenty of vocal synths but I don't personally know of any that do "fixed-do" as opposed just "oohs" and "aahs". I wouldn't be surprised if one exists though.
  2. Create your own with EXS24. So, in other words you'd record yourself or somebody else singing through the range of solfege syllables that you'd like to use. Then you'd create a custom EXS24 (Logic's sampler) instrument using those audio file(s). [tutorial] [vids]
