All deeper vocals (females can also encounter this depending, but less often) have issues. Vocaloid just doesn't handle deeper vocals as well as higher. So a lot of the masculine vocals tend to suffer this same problem, particularly the mature ones as of note as they go the deepest normally. Vocaloid has less troubles with higher vocals.

Wat noted it with Big Al], when he was first released. Since there are more higher pitched vocals (mostly due to the many female vocalists), its not always that common to encounter it. Oliver and Piko are both high pitched male vocals. Len is a low female voice (but still because it is a female voice, not that low in pitch compared to [[Piko and the range goes higher then him). So all 3 are less likely to have the same trapping as Big Al, Bruno, Gackpo, etc.

Its generally a common problem among syns, UTAU often has the same problem. I believe its a issue with wavelengths and how sound travels. But I know not the science to even explain why. This is an issue that will improve in time. It a lot more apparent tho with older syns and lower quality/tech ones. O_O
