SALUT!

Thank you for purchasing yet
another Xaoc Devices prod­uct. As you probably know,
the Ostakino expander mod­ule is designed to work with
a dual Moskwa setup. Note:
Using one sequencer unit with
the expander is possible but
will result in less than half the
functions being available.

The Ostankino adds a huge
amount of functionality to the
Moskwa sequencer and may

seem confusing at rst glance.

But it was designed to be
easy and intuitive to use and,
most of all, fun! The following

manual explains how.

2. INDIVIDUAL CLOCK
OUTPUTS

These sockets 9, obviously,
spit out the internal Moskwas’

rate so you can sync

clock
other modules to them. Note:
if there’s already an external
clock fed into Moskwa, the
corresponding clock output on
the Ostankino will just simply
transmit it unaffected.

3. INDIVIDUAL TRIGGER
& GATE OUTPUTS

There is a set of 8 trigger/
gate output sockets
able for each sequencer re­spectively. You can use these
to program rhythmic events

avail-

(i.e. patching a Bytom mod­ule) or just anything relevant
to the sequence. These outputs
can work in two modes:

Mode 1: To transmit the
gate (if the step is turned on)
for each step in the pattern
individually, set on the cor­responding Moskwa unit.

Mode 2: To generate trigger
impulse for each step indi­vidually, no matter the gate
settings on the corresponding
Moskwa unit.

In order to dial the desired
mode, hold the
button (for the A unit) or

for 2 seconds. After releasing
it, the button will change its
illumination – brighter when
the gate is being transmitted
from Moskwa and dimmed
when in trigger mode.

Note: Gate length setting is
global for each sequencer. If
the trigger (1/8) is set on Mo­skwa, Ostankino will generate
a trigger too, even if Mode 1.

CHIP REPLACEMENT

Ostankino requires Moskwa
microcontroller ICs to be

replaced. The new rmware

revision that takes advantage
of the expander functionality,
improves the performance and
adds some new features.

Turn your system off, then
unscrew and unplug the mod­ules. Put them on the table,
knobs down. Now, remove
the old chip. Pry it up gently
using a toothpick or tweezers,
as shown on [Fig.1]. Then, put

the new chip in place. Observe
the orientation carefully, the
notch points down! Then, gen­tly, push the chip until it sits
safely in the socket. Repeat the
operation for the remaining
Moskwa unit.

CONNECTING THE CABLES

Looking at the back side of
modules, attach the 16-pin
inter-connectors as shown on
[Fig.2]. The red stripe points
to the right on the Moskwa
(

expander header, remove

the jumper rst), and points

up on the Ostankino (a and b
header, should arrive attached
already).

Clear 50hp in your cabinet and
place the modules in it. Only
Moskwa A requires a power
cable now (you can simply
remove a power cable from sec­ond unit). The expander module
and second Moskwa will draw

their power from the rst unit.

Finally, check if the orientation
of the power cable is correct,
and thats it, you’re good to go!
