I mention the following as it may help others who are wanting to record
digital drums with a 'real' drummer:
I regularly play with a digital drummer where he triggers a Roland TD-8
VDrum module, with acoustic cymbals and high hat mic'd, and all is recorded
as audio in a VS-1680. Now we want to record some stuff with separation of
drum parts, but there is limited input channels for live recording in the
1680, so figured its time to record the midi into Logic.
We ran some experiments in recording his pads as midi data, with the main
objective being that the drummer would be satisfied that the midi triggered
module would be an identical performance to what he plays, hears, and what
is recorded in audio in real time. (I'm running LAM 4.5 on a PBG3 with
VXPocket with a MTPII).
For this test we had the same cymbals and high hat recorded as an obvious
way to hear how the audio vs midi jelled.
He played some beats with lots of 16th note triplets, and other swing
things. We listened to the audio recording on the 1680 and compared it to
the same track with midi triggering the module. And it sounded like crap.
All the notes were recorded with OK velocity, including ghost notes, but the
timing was off on denser passages.
I thought the problem was in the midi interface or that I was quantizing on
input. Made sure quantize was off and I put the MTPII in "Fast"
mode, but the same problem persisted.
Then it hit me, what should have been obvious from the start. We didn't turn
Local control off on the TD-8. When we turned Local Off, and he played
direct into Logic with midi through triggering the module, everything
sounded tight and accurate. Yess!
Before turning Local Control off, I was recording drums into a No Outup
instrument, so there was no midi loop present. Then assigning that track to
the TD-8 Instrument.
Guess there's enough of a delay in midi triggered data, compared to
physically triggered drum audio to make for a significant mis-match. The
thing I don't understand is that the notes that sounded out of time came
during dense passages. There wasn't a consistent delay, just certain notes
were out of the pocket.
Must also be that the drummer is monitoring the midi and playing with it so
his feel is adapted to the few millisecond delay that is inherent in midi,
in comparison to the physical trigger of the drum pads.
