Hi , i have a small problam.it is a bit hard for me to explain so i will try to give you much information that i can for you to understand my problam.
I have a motif xf6 and logic pro 9.
The way that i recording music is this way,don’t ask me why becuse it is another issue:
First i recording a midi region -for example drum,after that i’m recording it as an audio,so now i have an audio file drums.next track will be bass and it will be recerded also as midi first and than will become audio..but when the drum(audio) is playin together with the bass(midi) i can fell that they are not playing on the same time..there is a very small time space between then but my ear is notice this..so is it posibble that audio will play on the correct time togher with midi?
Hope you understand my problam
(and i also quantizing the mudi regiom before i turn it to audio)

You are running into latency issues. There is a tiny delay from when the MIDI leaves Logic to when the XF sees it, plays the note(s) and the audio gets back into Logic. If you can describe your recording setup in more detail we can help you track down exactly what you need to do.
