sysex in/out mismatch

kejace · Sep 14, 2003, 06:05 PM

When I send a sysex file trough a midiin/out loop with midiox the number of bytes recieved doesn't match the number of bytes sent. I suspect this is a bug in the drivers, is it an old problem or is there any solutions (buffer settings etc.)?
I use Version: 5, 10, 00, 3534 - debug and WinXP.

yes, there's a bug with SysEx buffers -- and it cannot be solved at the moment due to certain hardware/software limitations
the bug depends on the SysEx timings and buffer size
that is, if you output the data in, say, 128-byte blocks, the bug should not happen

Hi

You can in Sonar or Cakewalk edit the file called TTSSEQ.INI and add this in the [Options] section :

SysxRecordBuffers=128
PumpDataMsec=200

Second line gives a delay before sysex transfer
