Kemurikusa

This list covers any anime that utilizes vocal synths (VOCALOID, UTAU, CeVIO, Synthesizer-V, etc.) in some sort of way. This mostly focuses on direct usages of vocal synths within the shows, but some of the entries here are attached for more unusual reasons.

Note that I will not be counting song videos for this, nor am I cataloging simple references to Miku (so no Hyouka, for instance). I also may not have everything in-scope listed; these are just the ones I know about. If I'm missing anything, please let me know in a DM!!

The order's a bit messy due to odd overlap areas (thanks, Jashin-chan), but here's the basics:
-Shows based on Vocaloid song series [1-2]
-Shows with official, licensed voicebanks [3-5]
-Shows that utilize vocal synths in-show for non-musical purposes [3, 6-7]
-Shows with vocal synth characters (i.e., Hatsune Miku) [3, 7-11]
-Shows with vocal synths used in the music [1, 3, 9, 12-31]
-Shows that cover vocal synth songs [1-2, 32-35]
-Shows that reference vocal synth technology as a plot point [27, 35-36]
