fynv/ScoreDraft
ScoreDraft is a simple music/singing synthesizer that provides a Python based score authoring interface.

Another resampler for OpenUTAU. It's ported to Linux / Mac including lots of optimizations and compatible with OpenUATU. So if you wanna use OpenUATU on Mac/Linux, this is your only option as far as I see.
