Connections and Setup for correct Operation
Sync-Gen II is a true Stereo Plug-in. Two separate channels of pulses are required for correct
operation when used with your Innerclock Systems synchronisation interface.

Channel One (Left Hand Side) provides the continuous sync pulses from the Sync-Sequencer.

Channel Two (Right Hand Side) provides the continuous transport pulses from the TransportSequencer and the DAW Host Transport commands.
Soundcard Output Assignment
You will require a DAW soundcard with a minimum of four separate outputs for correct operation of
Sync-Gen II and your Innerclock Systems synchronisation interface. No DC Coupling or any other
electronic modification or special cables are needed.


Outputs 1+2 for your normal DAW Audio Playback
Outputs 3+4 for your Sync-Gen II Plug-in Playback
Levels
The Innerclock Systems Sync-Lock and Cync-Lock use sophisticated electronics and software to
convert full frequency AC audio signals into precision synchronisation clocks within 20 microseconds.
A pulse input signal of -20dB is the ideal operation level for reliable and jitter-free sync generation.
Too much or too little input signal will lead to erratic and unstable synchronisation. If your external
hardware does not slave-sync correctly, check the output levels of Sync-Gen II in your DAW Mixer
Window.
By default the output levels of Sync-Gen II are set correctly in the software preferences on first
launch. Certain soundcard outputs may be calibrated differently [-10dB, 0dB, +4dB] and you may
need to adjust the output levels of Sync-Gen II to match.
To do this see page 23.
These new levels are stored within Sync-Gen II preferences and will remain set until changed.

Other Connections
Y-Split for the Sync-Lock
On the Right Hand Side of the Sync-Lock there is a ¼” socket marked [Pulse Out]. This is actually a
dual function TRS [Tip/Ring/Sleeve] dual mono socket. With your original Sync-Lock Kit and SyncGen II LE package you will find a Y-Split adapter that provides access to both these functions.

Rhythmic Sync Pulse Output (Tip Socket)
The Original Sync-Lock Analogue Pulse output generated fixed 16th Note 20ms Positive 5v DC Pulses
to drive external sequencers, synthesizer EGs and drum-trigger inputs. We felt this was the most
useful rhythmic interval to drive analogue clock-driven arps and step-sequencers too.
A factory hardware update to the Original Sync-Lock and now standard on all Sync-Gen II LE kits
provides a wide range of quantized, rhythmic pulse intervals – 1 : 1/2 : 1/2T : 1/4 : 1/4T : 1/8 : 1/8T
: 1/16 – and these are selected by holding down the Footswitch. The generated pulses are 20ms
Positive 5v DC.

Footswitch (Ring Socket)
Connect the supplied DP-2 Foot Switch to the Ring Socket of the Y-Split Adapter. At the beginning of
each new bar of DAW playback if the Footswitch is held down, the next rhythmic interval is selected
and remains until the Foot Switch is pressed and held again at the next DAW bar marker.

LED Activity
There are four LEDs on the Sync-Lock.
Input Side
The two LEDs on the Left Hand Side of the Sync-Lock indicate when pulse signals are present at the
input. During normal operation, the [Audio Clock In] LED and the [Audio Start/Stop In] LEDs will be
lit continuously.
Output Side
The two LEDs on the Right Hand Side of the Sync-Lock indicate running status and tempo. The LED
under the DIN Sync socket lights [RED] when stopped and [GREEN] when playing. The LED under the
Midi Clock socket flashes [RED] at quarter note timing intervals.

Overview
(1) Sync-Gen II is a purpose-specific, sample-position accurate and tempo-grid precise External
Tempo-Sync and Transport-Control Generator/Sequencer Plug-in for the Innerclock Systems
Sync-Lock and Cynq-Lock external DAW synchronisation interfaces.
The Plug-in Interface can be seen as three distinct sections:
(a) The Sync-Pulse Sequencer
(b) The Transport-Pulse Sequencer
(c) The Options and Manual Control Section
8|Page
The Sync-Sequencer
The Sync-Sequencer is responsible for creating the raw audio pulses that allow the Sync-Lock and
Cync-Lock interfaces to generate their sample-accurate and grid-relative external tempo-sync. Midi
Clock and Din Sync require rapid PPQ (Pulses per Quarter Note) to keep time – 24 Pulses per Quarter
Note or 96 Pulses per Bar of 4/4. Working with such rapid fire pulses in a traditional sequencer
environment is complicated because most of the pulses required fall in between rhythmic grid
positions. They are not ‘heard’ as such but they must always be there to keep accurate tempo. The
Sync-Gen II Sync-Sequencer is unique because we have designed an interface that allows the user to
program and swing the sync pulses in a variety of musically creative ways while the software code
always maintains the correct number of outgoing pulses to keep everything perfectly in time.
Global Settings
Global Swing: Minimum = 50% [OFF] Maximum = 75% [Full]. Change the value of these
thumbwheels using the mouse. The Swing setting here is applied across all bars in the pattern unless
they have specific swing settings of their own.
Global Swing Interval: [8ths] or [16ths]. This determines if the sync pulses generated by Sync-Gen II
swing in 8th or 16th note rhythmic intervals.
9|Page
Global Pattern Length: [1] thru to [8]. This sets how many bars will be looped within the pattern.
Global Pattern Rate: WHITE Numbers – Normal Operation - [12], [16], [24], [32] and [48]. Midi
Clock and Din Sync slave devices require 24 PPQ (Pulses per Quarter Note) to match a Master DAW
tempo at a 1:1 ratio. A setting of [24] which is the default value provides a 1:1 tempo ratio between
the DAW, your Innerclock Systems interface and your external devices. If the DAW is playing at 120
BPM, the external devices will play at 120 BPM also. A setting of [48] or [12] will mean that external
devices play at double and half the DAW Tempo respectively. Settings of [16] and [32] provide for
half time and double time external triplet sync.
Global Pattern Rate: RED Numbers – Special Mode - [32], [24], [16], [12], [8] and [4]. When the
numbers shown here are in RED, the Sync-Sequencer generates one pulse for every active step. By
connecting a simple breakout box to a single Din-Sync output from either the Sync-Lock or Cynq-Lock
interfaces it is possible to gain access to the raw Sync Pulses on that specific port. Connecting a cable
from the breakout box to a Step-Sequencer or Synthesizer EG provides direct clocking from SyncGen II and your DAW Application. Using these Special Mode Global Pattern Rate values provides
variable clocking rates and also allows full pattern programmability because the Sync-Sequencer
Steps provide 1:1 Pulse Generation.
10 | P a g e
Individual Bars
Step Select and Status: There are 16 individual step switches and lamps across the top of the SyncSequencer section. By default all Steps are [On] and [Active]. An active step generates a specific
number of sync pulses as set by the [Pattern Rate] and/or [Bar Rate] thumbwheel selectors.
Individual steps may be switched on/off while the DAW is playing without altering sync stability.
Bar Indicator/Selector: Sync-Gen II provides a maximum of 8 bars of looped programmable Sync
Pulse generation. You may select any pattern Loop Length number [1-8] using the [Global Pattern
Length] Thumbwheel. Select any bar with a single mouse click. This shows the steps and the
individual parameter settings for that specific bar. Bars may be selected for editing while the DAW is
playing without altering sync stability.
The Bar Indicators can have three colour modes depending on running status:
Full Red – This is the Bar that is currently playing and is also Active for Editing.
Red/Yellow – This is the Bar that is currently playing.
Yellow – This is the Bar that is Active for Editing .
Active Bar Edit: [On] or [Off]. Select any bar with the mouse and switch [Active Bar Edit] to [On].
The parameters [Bar Swing], [Bar Rate], [Bar Start Step] and [Bar Length] are now active and most
importantly override the Global Pattern settings for that specific bar only.
11 | P a g e
Bar Swing Interval: [8ths] or [16ths]. This determines if the pulses generated by Sync-Gen II swing in
8th or 16th note rhythmic intervals for that specific bar only.
Bar Swing: Minimum = 50% [OFF] Maximum = 75% [Full]. Change the value of these thumbwheels
using the mouse. The swing setting here is applied only to the Active and Selected Bar.
Bar Rate PPQ: WHITE Numbers – Normal Operation [12], [16], [24], [32], and [48]. This allows
synchronized tempo changes for individual Bars within a looped global pattern. Same information as
for Global Rate - Slave Midi Clock and Din Sync devices require 24 PPQ (Pulses per Quarter Note) to
match a Master tempo at a 1:1 ratio. A setting of [24] which is the default value provides a 1:1
tempo ratio between the DAW and your external devices. If the DAW is playing at 120 BPM, the
external devices will play at 120 BPM also. A setting of [48] or [12] will mean that external devices
play at double and half the DAW Tempo respectively. Settings of [16] and [32] provide for half time
and double time external triplet sync.
12 | P a g e
Bar Rate PPQ: RED Numbers – Special Mode - [32], [24], [16], [12], [8] and [4]. When the numbers
shown here are in RED, the Sync-Sequencer generates one pulse for every active step for that
specific Bar only. By connecting a simple breakout box to a single Din-Sync output from either the
Sync-Lock or Cynq-Lock interfaces it is possible to gain access to the raw Sync Pulses on that specific
port. Connecting a cable from the breakout box to a Step-Sequencer or Synthesizer EG provides
direct clocking from Sync-Gen II and your DAW Application. Using the Special Mode Global Pattern
Rate values provides variable clocking rates and also allows full pattern programmability because the
Sync-Sequencer Steps provide 1:1 Pulse Generation.
Bar Start Step: [1] thru to [16]. By default all bars start playback at Step 1. Changing this setting in an
Active Bar changes the Start Step number for that bar only.
Bar Length: [1] thru to [16]. An individual bar may have any set length between 1 and 16 steps.

operational principles but instead controls the Transport side of the Sync-Lock and Cynq-Lock
interfaces. This unique feature allows you to decide where you want your slave devices to Start, Stop
and Re-Start anywhere within a sequence pattern.
Step Select and Status: There are 16 individual step switches and lamps across the top of the
Transport-Sequencer section. By default all Steps are [ON] for continuous normal operation.
Individual steps may be switched on/off while the DAW is playing without altering sync stability.
Bar Indicator/Selector: Sync-Gen II provides a maximum of 8 bars of looped programmable
Transport Pulse generation. You may select any pattern Loop Length number [1-8] using the [Global

Clicking the mouse in this field you may can select either [Next Bar] or [Next ½ Bar]. This sets
the quantize value for the [Manual Start] and [Manual Stop] buttons on the front GUI
panel.
Out Level
Clicking on this tab opens a new window that shows the following:-
22 | P a g e

Output Level Settings: [1-16]
These two parameters set the master output level for the Sync Pulses [Left] and Transport
Pulses [Right] of Sync-Gen II. Default settings are [Left-03] and [Right-01].
Swing Blur: [Off, Small, Medium]
When set to [Off] any swung pulses within a bar are exactly the same in terms of rhythmic timing.
When set to [Small] each second set of swung pulses has a small degree of random push or pull
applied to the timing of the sync pulses. Because the initial and subsequent odd pairs of pulses are
still grid-accurate, the overall resulting feel is very tight against the DAW audio playback but the
subtle movement in the even pairs makes for a more natural swing. A setting of [Medium] is more
pronounced.
23 | P a g e
Midi Panel Settings
All parameters inside Sync-Gen II may be assigned a Midi Controller.
Clicking on this tab opens a new window that shows the following:-
Click on the [Parameters] Tab and select any parameter you wish to control remotely. Next click the
[Learning] button so that it is lit green [Active] and then press or turn your Midi Controller or Midi
Key to assign it to that parameter. Click [OK] to return to the main screen.

Thanks: To the Beta Team and our loyal customers for waiting while we got this right.
To our customers past and present: DAWs will change over time of course and there may be things we missed in all our
strivings to build Sync-Gen II. After nearly two years of code crunching and scope analysis and beta testing over many
continents we have a very good grasp on the workings of our software and how it integrates with all the host applications.
If something seems odd, if you think something could be done better or simpler, or if you feel a new feature might make
Sync-Gen II a better sync system – please let us know.
Respect to you for knowing the difference and supporting what we do.
