I have still no luck. I installed latest hosc and hsc3 from darcs repo, tried the attached example program which uses the new function writeNRT, and got the following output
$ ghci NonRealtime.hs *Main> nonrealtime Loading package fps-0.8 ... linking ... done. Loading package binary-0.2 ... linking ... done. Loading package parsec-1.0 ... linking ... done. Loading package network-1.0 ... linking ... done. Loading package hosc-0.1 ... linking ... done. Loading package hsc3-0.1 ... linking ... done. Using Altivec: no *** ERROR: open directory failed 'synthdefs' start time 0 *Main> :! ls -al tone.* -rw------- 1 thielema users 182 2007-08-12 19:19 tone.aiff -rw------- 1 thielema users 256 2007-08-12 19:19 tone.osc See the attached OSC file in order to see if it matches the one you can produce. If my OSC file matches yours then something with my SCSynth is wrong, if it does not match, maybe ByteString or Binary is wrong. Thanks for the help!
