hello,
I found this interesting piece of information..
(I did something like this - and it's also described in the same
article - with my atari: shuffling a 606 by chaning the master tempo
every 16th)


How to shuffle 606
(from http://www.dinsync.com/)

(...)
So what you have to do is send an irregular click signal into the
dinsync port. This involves wiring a jack->dinsync cord and
triggering dinsync from another machine. To make a jack->dinsync
cord, you have to connect the TIP wire of the jack to PIN 3 (click)
of the din plug. The RING wire of the jack should be connected to PIN
2 (ground) of the din plug.
If you plug the jack into an output of a drum machine with a trigger
output and the din plug into your 606 dinsync in socket, your 606
will be ready to sync. However, you can't hear it yet because you
still need to connect PIN 1 (run/stop) of the din plug to a run/stop
trigger from another piece of gear. This can be anything you want -
if you can make your sequencer send a click when it starts and stops,
that'd be fine. Otherwise you can "jumper" PIN 1 from another dinsync
machine over to PIN 1 of the 606.
The 606 should now advance one step for every 6 (or 3) clicks coming
through PIN 3. Now, assuming you have a decent sequencer providing
the click output, you can vary the space between the clicks like this:

| step 1
| step 2 |
1-----2-----3-----4-----5-----6-----1---2---3---4---5---6---1-----2-----
etc

This way the second step will finish faster than the first, which
will create a shuffle effect. Bear in mind it's probably alot easier
just to buy a MIDI/dinsync converter to achieve the same effect; i've
only included this for people who want to keep another dinsync or
click-based machine as the master.

I'd like to generate my own (shuffled) sync-clock by playing 6 short
notes with my mcv1.

I'm not shure, if I understand this correct..

roland DIN SYNC:

from left to right:
3 tempo clock
5 fill in
2 ground (middle pin!)
4 reset & start
1 start/stop

. . or: ...
... . .



this is the tempoclock pin -> . .
...


does the 707 understand 'reset & start'
(could be cool to restart the pattern by sending a trigger..)

with compliments,
