RE: Beat Sync For DL4??
Hi,
good luck with your experiments,may i suggest that instead of using a
transistor,you wire one quarter od a cd4066 analog switch,driven by your
led/opto device?and for other modes,wire in series a small toggle switch
to disable the beat sync function...the advantage of the 4066 is that it's
bidirectional,can work from 3 to 18 volts,and takes virtually no power
from the dl4...
all the best

it is my firm and avowed intention to take the bottom off of my dl4 this
weekend and put a voltmeter across the relevant switch. that is, if my dl4
is actually around.... my band's gear is split between our london studio
(i.e. my house) and a rehearsal space in stockport, manchester, and I
can't quite remember where the dl4 is at. but I'm going to make this
happen.
I want to develop something very simple- at most, a 3.5mm jack socket and
a transistor/opto-isolator/handful of resistors to add either internally
or externally to the dl4 (or actually any tap tempo device- the vortex
springs to mind, and the dod dimension12, which I've been having a great
time with btw).
this would be driven by any clock that can make an LED light up... so one
might have to add a socket to this other bit of gear too, but I think
that's a small price to pay for the functionality.
I have mentioned devices that can be bought or built quite cheaply that
will derive this pulse from midi-clock, but I'm guessing folks might not
need to do this if, for instance, they already have something that's
midi-clocked that blinks an LED at the right rate. I have a bunch of midi
sequencers that flash their lights and produce gate signals... a more
elaborate solution might include a counter circuit that would divide down
such a pulse to produce "taps" at half- or quarter- rates.
I'm not sure what to do about defeating or modifying this function when
the dl4 is switched to sample-mode, because the relevant footswitch is
doing something different then.
anyway- watch this space.
