I didn't see anybody answer this, and none of my Roland manuals (TR-808, 
MC-4) seem to specify what the DIN input sync socket takes.  For 
Gate/Trigger/MPX OUTPUTS though, Roland seems to be going with 12 to 15 
volts.  However for the external sync 1/8" connector and Gate inputs on the 
Roland MC-4 sequencer, they specify a threshold of 2.5 volts to trigger.  
Don't know if this helps.

Ignore my response.  I was just informed through private mail that Roland 
uses 5V for clock/sync purposes.

It appears that going IN to drum machines, a +5V level is OK. Coming OUT,
they use like +12V.

Checking the service notes on my Jupiter 6 shows the external cont for
slaving the arpeggio 1 step/clock to be 'a voltage more than 2.5V'. I
have at times used my Roland TR-727's clock out to do this.

Out of the sync24? Not on my 606 and 303--the clock pin (the center one I
think) reads 5V coming out...

Also, the Jomox XBase09 sync24 output is 5V, and that's rock solid for me
too.

I assume that that's what you were asking about Paul, the sync24,
confusingly called "dinsync" sometimes... 'cause there aren't other clock
inputs on these smaller devices (unlike the clock inputs in a lot of the
keyboard synths, SH-101, etc.).

hello all,
well my sketchy knowledge of drum machines is as follows:
Roland Dinsync runs a +5v pulse (ie you can build a din to jack cable and
use the 'gate' signal unprocessed)
I believe Korgs run the same
Simmons Modules like something akin to a +5v pulse to trigger them
if this is going about to turn into a motm xxx pulse divider design thread,
then here's my pitch: why not have a range output voltages available,
selected either by jumpers or a preset..?
here's a wacky idea - why not have the option of (oh dear, here we go)
modulating the output voltage via a second input jack that you'd connect to
an lfo, s&h - you'd have to do something about the pulse length, but hey i'm
not an engineer (though it it looking like i'm getting dragged in that
direction kicking and screaming)
actually a "skank switch" would be quite nice, that takes the incoming
trigger pulses and automatically delays the outputs by what would be defined
in scientific terms as "a period of time that equals one skank" - maybe i
should lay off the king tubby cds for a while
erm, food for thought..?
cheers

erm, delete that - i meant +12v
too much king tubby... 
cheers

The question is: do they have a minimum spec? I +5V enought to cause
a trigger?

I *really* don't want to have anything bit +5V outs.

um, the thing with our simmons though, is so much as look at it and it'll
trigger itself.
though being the broadminded liberal man of the world that i am, i
personally can't see the justification for anything other than +5v :-)

You can run audio in it? Seems like that same "divide by this, and synch with 
that" guy wanted to run audio into everything! I bet he's really looking 
forward to this!

I should say that the ARP (and other synths which I can't remember) expect to 
see a 10V gate, so this might be a place for one of those programmable 
jumpers.
