Subject | MIDI timing irregularities |
Hello, I'm a new Csounder and I experiment some timing irregularities with the MIDI OUT opcodes. Another strange thing is that when I compile a orc/sco with " -Q0 -n " or " -Q0 -o /dev/null " as it is indicated in the Linux-midiOUT text file joigning the 3.48X Linux distribution, all the notes of the score are read at the same time with no more regards at their placement. I have to maintain "-odevaudio" for the things to work. Is there a way to solve these problems ? In a score where I have both a bass drum on the beat (a simple soundin) and a MIDI instrument off the beat, the both together are not all right. Francois Ernst. Thanks to all the Csound Community. PS: I have OSS Linux and a SB64 gold, RH5 linux 2.0.32 on a 233mhz PPRo/64 megs |

After a long search: The solution is to reduce "-b" value. 1024 is the default one, 512 seems ok. A comment should be add in the readme file LINUX_MIDIOUT.TXT F.ernst |
