I have used the TCP transport data type and derived a File data type from
it. However I got the error that the OSC message is longer than 8192
bytes. Thus I reversed the byte order in the length encoding:
let b = encodeOSC msg
n = fromIntegral (B.length b)
in B.hPut fd (B.append (B.reverse (encode_u32 n)) b)
Now it seems that the times are not interpreted properly:
$ scsynth -D 0 -o 2 -N glissando.osc _ glissando.aiff 44100 AIFF int16
Using Altivec: no
*** ERROR: open directory failed 'synthdefs'
start time 0.501933
nextOSCPacket 1.10536e+07
*** Exception: waitForProcess: interrupted (Interrupted system call)
Maybe this is still an issue of byte ordering. Server-Architecture.rtf
states that values must be in network byte order. What is 'network byte
order' in the case of files?
