Noticed that MIDI music doesn't play at all in Blood in v1.9.1, but it's still working in Duke Nukem 3D.
Seems to be completely muted or is not initializing at all as in previous version v1.8.1 where it did work.
P.S.
v1.8.1 is the first Raze version i have tried out and it feels great, nice work

Only thing i noticed is that the MIDI music level feels very unbalanced sometimes (barely auible in some levels and high in others). Not sure if it is a Raze bug though, hence i only mention this in post scriptum for now.
