Ive tried using the bpm counters on dj consoles - was never very impressed - whole numbers of bpm counts aint fine enough to tell if you can go hands off on the desks and spend the next mins or so fiddling with controls and fx while you blend two tracks, so just setting a synth to the same tempo never holds for very long.
Ive tried treating the tempo control on synths like a deck's pitch control for manual syncing and it just aint fine enough - needs tiny fractions of bpm really. Tap tempo aint bad - easier at least, but v hard to get accurate.
I guess the Dj will just have to keep sync - theyre used to that anyway
Red sound midi sync boxes were discontinued last week and they have none left - Grrrrrr!
Interesting you mention the Kaoss pad - is that a v2? I was thinking of getting one for use here and with a friends DJ rig.
