This is an NTP/UTC issue.
OSC timestamps are in NTP, but at a user level the
hosc/hsc3 libraries (and sclang) work with UTC.
The encodeOSC function from hosc converts
from UTC to NTP.
In your text, replacing:
> nonrealtime =
> do let tsMsgs = map (uncurry Bundle) msgs
with:
nonrealtime =
do let tsMsgs = ntpZeroed (map (uncurry Bundle) msgs)
and adding:
ntpZeroed :: [OSC] -> [OSC]
ntpZeroed l = map f l
where f (Bundle t c) = Bundle (t - 2208988800.0) c
f (Message _ _) = undefined
works here.
Also, given the a post 30-July-2007 version of
http://slavepianos.org/rd/sw/sw-76/Rhs/Score.hs
the below is the nrt test file i have, it first plays
the score in rt, then writes a score to "/tmp/nrt.score"
and renders it to "/tmp/nrt.wav".
Regards,
Rohan
