Making a new midi file

Hi,
Midi-ox is fantastic nothing less ! 
I use it with my Qy-70 sequencer and I can even input events with the translation map in the pattern mode.
But there is a latency Ex: for a note-on event at let's say 2:248 the map out a Ctrl 11 expression event return at 2:250
Can I do something the return the ctrl 11 at 2:248 ?
Also it is possible to log all events in a file and rebuild this file in midi format ?

Are you saying there is latency inside the QY-70 mapping? Or are you talking about sending an event into the computer, mapping and re-recording it into the QY-70? If so, that is not very much latency at all. What's the timebase for the event times you specified? 480 ppq? 960 ppq?
You can log events using "MIDI To Text" format, and then convert it to a MIDI file by using T2MF (available on the website). You'll need to edit some things (the tempo for instance).

Yes and the timebase is 480 ppq
Is the log events using "MIDI To Text" format works for the XG format to ?

Thank you SergeD

The reason there is some latency is because it takes some physical amount of time for an event to be transferred into the computer, mapped and output back to the device. However the amount of time you indicated is not very long: the difference between 2:248 and 2:250 is 2 ticks. At a timebase of 480 ppq this is roughly equal to 2 milliseconds at a tempo of 120 BPM.
MIDI to text should work fine with XG. I mentioned that you might need to edit the tempo in the log file to match the tempo of the song in the QY-70. This is only required if you need the events to line up on the same measure boundaries as the original. It is not absolutely required, and the song will sound the same regardless.

Based on your report, I donwloaded a fresh copy of MF2T utilities. I created a MIDI-OX Log in MIDI To Text format. I closed MIDI-OX and viewed the log in Notepad to make sure it was complete. It looked something like:
# MIDI-OX Version: 6.5.0.340
# MIDI To Text Format - Opened: Fri 22-Nov-2002 02:10:46
# The first MIDI event received will initiate timestamps
MFile 0 1 120
MTrk
0 TimeSig 4/4 24 8
0 Tempo 500000
0 On ch=1 n=60 v=81
81 Off ch=1 n=60 v=108
... (many more events)
TrkEnd
# MIDI-OX: MIDI To Text Format - Closed: Fri 22-Nov-2002 02:11:08
I then ran T2MF on it (T2MF MIDILOG.TXT Test.mid) and got a MIDI file generated: no error message. It seems to be working OK. It sounds like maybe something is wrong with your logfile: did you choose to save it in "MIDI To Text" format?

Sorry Jamie,
the file was an experimentation where I pulled out some lines.
Everything is ok now,
SergeD
