Re: Kontakt 5-Studio Drummer- Grooves-Not synching wit...
It is probably because it isn't a "real 6/8"
I pulled up Studio Drummer and found a groove labelled as Blues Rock 100BPM 6 - 8 The problem is that this is not a "real 6/8" - it is still a quarter note beat with the inner notes being played as triplets. A 'real 6/8' would have the dotted quarter as the beat (where you would clap or tap your foot) and the inner notes being normal 8th notes. Do they sound the same? Yes. The difference is that the BPM would be a 33% difference for them to line up.
If your Logic file is in 6/8....eeek. It isn't going to work (easily) with the way they programmed the beats since they are using triplets - and those would play as triplets against the quarter note pulse in your 6/8 song.
In Logic - and other DAWs of which I am aware - the tempo indication is ALWAYS in reference to the quarter note (not necessarily the toe tapping "beat"). If you choose a non-quarter note time signature, the tempo shown is still referencing the quarter note within that metric. If you tell Logic you are in 2/2 (two half notes per bar) it will click only on the half notes, but the quarter note will have the numeric value you choose. That one seems easy, but since 6/8 (or 12/8 etc) have a 2:3 ratio, that is when the click starts to sound wrong.
My two suggestions are:
1) Just play what you want via MIDI. You have the Studio Drummer sounds - just play it in; in layers of course.
2) Make a new song in 4/4, put the same groove you love into it (note that it will sync correctly with the tempo). Take a screen shot of it so you can see the order of the notes and timings for reference. You can delete it now. Go to your 6/8 song, import in the MIDI file into a track with Studio Drummer on it, Quantize to 8ths, then (this is good part!) manually move over the notes until they are in the right spot. This is where referencing the screen shot will help - just remember that you will need two full measures to equal one measure the way it was played.
Once you do it right for this 2 bar segment, you can loop it and easily create variations.
I hope this helps.
