Am I reading this right in the manual?
Cross DJ Manual pp. 89 wrote:Sometimes tracks do not use a strict 4/4 signature throughout the whole track. let’s assume you have a track with a beat length that cannot divided by 4 without a remainder, or another track with a tempo change where one part of the track has a different BPM than the other. For those tracks you can add a user beatgrid. The number of additional user beatgrids that you can add is unlimited.
When you add a user grid you actually set the position of a new downbeat (the first beat of a bar) and this downbeat can be set to any position of the track.
Ok... so let me see if I have this understood right. I can define the downbeat of each measure using user beatgrids to define the changes in tempo throughout the song.
In instance 1 - if I have a track playing with a constant bpm of 108, and I want to sync a track like Get Up by James Brown that has a live drummer that wavers - it will warp the James Brown track so that the beat markers hit properly.
In instance 2 - If I have a track like Lil Louis 'French Kiss' that goes from about 120bpm down to 40 bpm and back up - if another track or samples are sync'd to it they will slow down and speed back up with that track.
In instance 2 - Or will it force the track to play at a constant BPM - effectively warping the tempo change out of it?
I only ask, because if this is the case, it's the 3rd DJ software I've seen with this feature - and it's actually pretty rare. Torq after 1.5 had it, MixMeister had it... and if I read correctly, Cross.
Of course I can use it with something like Dave Brubeck's 'Take Five' to mark each downbeat.... but working with 5/4, 3/4, 6/8, 7/8, and other time signatures is a discussion for another time...
The only think I need now is to be able to send the tempo fluctuation out of Cross to MIDI Beat Clock so I can feed it to other devices as I start working on production stuff.
(And a MBC input would be nice too, but I'm more interested in the output right now.
).
