Usually, an 'Empty' project and 'Create VST Connect' should get you up and going immediately.
If it doesn't, this guide may help to find out why. Of course, we assume that you have read the manual in the first place.
For the experienced signal charts reader, here's an outline:
Go to menu Studio/Audio Connections - in earlier versions, that was Devices/VST Connections, not to be confused with "VST Connect".
Route from Performer
Look here if you cannot hear the Performers' signal.
In order for you to hear the Performer at any time, make sure that
you are using the Control Room Monitor outputs instead of the main
First, if not already set so, disable outputs from your main Output bus.
Select the 'Outputs' Tab and set device and 'Device Port' to 'Not
Save it to some preset (e.g. 'Stereo Not Connected') for later reference.
But now I don't hear anything anymore?
So now go to the 'Studio' Tab and assign your speaker hardware ports to
the 'Monitor 1' channel (or whatever your Monitor output is named):
Let's stay here for a while.
Of course, the 'Control Room' button on the top must be activated (blue).
There should be a 'Talkback' channel so that the Performer can hear you. We'll talk about that later.
For a quick start, your hardware 'Audio Device' and TB mic port should be assigned here to 'Device Port'.
The Cue (VST Connect) channel has been created by the 'Create VST
Connect' function. Leave it 'Not connected'; the VST Connect plugin
grabs hold of this signal and sends it to the Performer. Again, the
'Route to Performer' is beeing discussed later.
Of importance here is the 'Monitor 1' setting. Here, and only here
should you assign your speaker outputs to the 'Device Port' column.
Save the Studio to some preset (e.g. 'VST Connect') for later reference.
Let's have a look at the Control Room (CR) Mixer to see why it is
important to use the CR Monitor. Open it via menu Devices/Control Room.
Click the 'Setup' Tab at the bottom right, and Ctrl/click the 'Main' section to have it look like this.
Note the 'Main' section at the bottom. You can see the 'VST Connect Monitor' below the Main output.
This allows the VST Connect plugin (VST Connect Input channel) to
route its signal directly to and mix it with the Main output so to bypass all delay
lines that would otherwise cause the Performers' signal to arrive at
your speakers late (delayed).
As explained later, in the project, make sure no Track Monitor is
active on tracks fed by the VST Connect plugin; that Input Monitor
signal is delayed significantly, and you should not want to use it. You
want to hear the Performer only directly via the VST Connect Monitor plugin and
not anywhere else.
If you don't hear the performer, this plugin may be missing or switched
off. Try 'Repair VST Connect'. Also make sure that the "MONITOR/PERF" dial
on top of the VST Connect plugin (shown later) is cranked up.
If you create a 'Phones' (or other) monitor channel in the VST
Connections/Studio Tab mentioned above and use that for monitoring the
Performer instead of this Main output, you may have to move the VST
Connect Monitor plugin there instead. If you deal with your own Monitor
channels, we assume that you know what you're doing and understand that
concept by now (VST Connect Monitor plugin post extra Monitor or Phones output).
Route to Performer
Check this if Performer doesn't hear things as planned.
Open the 'Inputs' tab. The 'VST Connect' Input Channel that was created
by the 'Create VST Connect' function should be visible and look like so:
That is, no harware ports should be assigned here. You may imagine
the signal that the Performer sends to you is 'replacing' the hardware
ports that you would assign otherwise if you wanted to record yourself. Like the Performer 'speaking into my mic'.
In the Control Room picture above (Route from Performer),
you also see the 'Cue (Vst Connect)' channel at the top. Make
sure it looks like this and that the VST Connect Cue plugin is
The signal generated and sent to the Performer is created via the
Control Room Cue channel functionality. This is explained here and it
all applies to both a 'local' studio situation and when recording via
Many users have never recorded anybody but themselves
with a DAW. In a recording studio, the engineer uses the Control Room
Mixer to create a so called 'cue mix' (sometimes refered to as
'Aux' or 'Foldback', a term often used for the same purpose in a live
monitoring situation). You may check the Cubase/Nuendo manual for more
features of the Control Room. Right-click the 'Cue (Vst Connect)'
header to see some options regarding Cue Mixes.
A cue mix is what the Performer hears. This can be the main mix, a
connected CD player or other external input; the source of what the
Performer hears is determined in the Control Room Cue Mix Channel. This
also includes the studio Talkback and click (metronome) signals and
according levels. Click to open the 'Cue (Vst Connect)' channel and
select the 'Mixer' tab at the bottom:
Of course, the channel should be activated (blue button).
The circular 'TB' button must be activated at all times and should be
left so, even when Talkback is off, otherwise the Performer will never
hear your talkback microphone.
The default source is the mixer cue mix ('Cues' button). This is used
to generate and send a dedicated mix of mixer channels to the Performer.
It is an individual mixdown of all tracks and other mixer channels, the
mix beeing independant from the main mix. You compose that mix using
the cue mix sends in the main mixer (menu Devices/Mix Console):
Note the Control Room Mixer again, which can be configured to be visible in the main mixer window as well.
See the 'Cues' row in the middle of the mixer (use the 'Racks' item at
the top of the 'Mix Console' window to activate its visibility if it
doesn't show). The active (green) levels determine what the Performer
hears when the Control Room 'Cue (Vst Connect)' channel is set to
'Cues' (blue button).
This requires some thought; if the Performer complains not to hear
certain tracks, make sure that they are sent via the 'Cues' send
sliders. You should use the 'Create Performer Track' of the VST Connect
menu, or 'Duplicate Track' in the arrangement to clone an existing
Performer track in order to have this set up so that the Performer can
hear his or her own performance when reviewing a take. Obviously, the
Cues send has to be active; there is a tiny button at the left of each
of the Cue send levels. There is also another tiny button to toggle
pre/post fader mode: post fader (default) means that when you change a
channels' fader (here, the white handles), the cue send signal will
also be changed accordingly. To prevent that, pre fader may be engaged
for each Cue send individually, which makes the Cue send entirely
independent from the studio mix.
So this way, you can present an individual mixdown to the Performer.
Alternatively, and if that all sounds like rocket science to you, just
click the 'Mix' button (becomes orange) at the top of the Control Room
'Cue (Vst Connect)' channel instead. Now the Performer will hear what
At no point will the Performer want to hear his or her own signal,
except when reviewing recorded takes. So again, do not engage any input
monitor for Performer tracks in the project. Also make sure to have
monitor mode set to 'Manual'. In the 'File' menu, select 'Preferences'
and at the bottom left, click 'VST':
Set 'Auto Monitoring' to 'Manual'.
If the Performer can hear the music but not your voice, there is something wrong with your Talkback settings.
First, as noted before, you must have your Talkback (TB) microphone
assigned to the Control Room Talkback channel. When you 'Create VST
Connect', this has been offered to choose, so make sure there is a
Talkback Channel in the menu Devices/Control Room/Studio tab (see 'VST
Connections' picture above) and that your TB mic is connected there.
Then, Talkback must be enabled. VST Connect automatically switches off
(disables) TB during playback and recording. The reasoning here is that
your talking during playback or recording is not in sync (delayed) for
the Performer to hear, so it would only confuse him or her. You may
choose to use 'Rehearse' mode described later, but not for recording
(there is no 'jamming' mode in VST Connect).
You can see the green 'Talkback' button at the bottom of the Control
Room mixer above, indicating that TB is active. When you speak, you
should see the meters of the Control Room 'Cues (Vst Connect)' channel
move. That meter shows everything that the Performer hears (also
visible in the VST Connect plugin discussed later) and actually
corresponds to the VST Connect Monitor Mixer 'STDIO' channel. Finally,
as mentioned before, the circular 'TB' button in the Cues Channel must
also be activated. If your TB mic still doesn't cause the Cues meter to
move, double check your hardware and Vst Connections Studio tab
Here's a tip...you may have to manually switch Talkback often, in that
case you may want to assign a keyboard shortcut (like 't') via
File/KeyCommands', 'Control Room/Talkback on/off'.
Vst Connect plugin
The top buttons of the Vst Connect plugin are connected to some of the items already described:
- Talkback Control:
'TALKB' - obviously mirrors the Control Room 'Talkback' state
'REHRS' - rehearsal mode. In this mode, you must not record, as
recordings would not be in sync with the playback. This is just to
coach the Performer during playback. In rehearsal mode, Performer usually just
listens, because if he or she performs along with what he or she hears, it will not be
synchronous on the studio side. When rehearsal mode is off, Talkback is
automatically switched off during playback or record to avoid confusion
due to the delay between studio and Performer.
'TO PERF' - corresponds to the Control Room 'Cue (Vst Connect)' level.
'DIM' - if you listen to the Performer via speakers instead of
headphones (the latter beeing recommended so to avoid the Performer to
hear his or her voice with an echo), there is the 'Dim' function in the
Control Room which dims (lowers) the main Monitor output so to avoid
feedback. The 'DIM' knob is connected to the 'Talk Dim' level in the
Control Room Mixer Main Monitor 'Mixer' section shown above.
'Cue' - linked to Control Room 'Cue (Vst Connect)' meters. You can see what the Performer hears here.
'PERF' - this determines how much you hear of the Performers' signal via the VST Connect Monitor plugin discussed above.
More on the Rehearse button: It
overrides the automatic switching of the talkback function. When it is
off and the preference is set so, as soon as you start playback,
talkback becomes de-activated. This is because usually the Performer
doesn't want to be confused by sounds and talking from the Studio (Control Room). In situations like coaching however it may be desired to leave TB on all the time, this is what the
rehearse button does. Keep in mind however that there is a long delay (as set by the Remote Latency parameter) which can be quite confusing. So for instance when you sing along to what you hear it will be significantly out of sync for the Performer. Thus, usually you will want to leave everything as it is (Rehearsal off).
How sync works
- Studio hits start. Appearently, nothing happens on the Studio
side for as long as the Remote Latency setting allows (one second
- in fact, during this time, Cubase/Nuendo has started to "play back" internally, providing the cuemix stream to the Performer.
- The Performer performs to this cuemix and sends his audio performance
back to the Studio. This all has to happen without glitches within the
time given by Remote Latency
- now when the latency period has passed, Studio is ready to play back along with the Performer audio in perfect sync
As such, you are right to say that Remote Latency is a crucial setting.
But the bargraphs are there to help; each shows 1/2 second of time, and
the bar indicates how much is available (at 50%, 0.25 sec audio are
So, the Remote latency setting is the first one to look at when there are dropouts.
Some more Control Room tips
When you record somebody next door like in a standard audio
recording situation - which hasn't changed for more than 80 years now -
you will find a studio equipped with a Control Room and related
technology on the desk, even in the early days of broadcast. There you
find that you have to provide a cuemix and talkback to the performer,
and the Cubase and Nuendo Control Room is a great addition that enables
you to fully control this recording workflow.
VST Connect picks up on that standard recording and provides almost
exactly the same workflow even though the Performer is many miles away,
like no other system does - other approaches require the Performer to
be skilled, own a DAW and be able to operate it, aquire and load a
project that has to be kept in sync all the time and so forth. VST
Connect frees you from all of that and provides accurate drop in/out
etc. End of advertisment :-)
Now, many users know how to record themselves and that works fine without Control Room functionality, so we provided the
Create VST Connect function to make it really easy - a one-click operation which only leaves the Talkback mic to be connected
and you're ready to go. The default setting of the Control Room is such that when the CR is enabled globally,
the output monitor will be active. So the assumption is that when you start to work with CR settings, you should know what
you do and it has a lot of great possibilities, but if global routing is changed, things can certainly go wrong.
About Cue Sends: If you add a new audio (or fx/group) track, the cue send is not initially activated, so you may have to do that.
But there are some nice convenience functions in the cue channel itself (remember it's in the Control Room Mixer).
Right click on the "Cue (VST Connect)" bar (this is your friend) and you get various options for selected channels like
enable/disable/reset cue sends, set them all to a specific level, or apply faders and pans etc.
You don't have to "create" cue sends, because of the Control Room
CueMix's existence, there is a cue send for each mixer channel
In an exsisting project with some audio tracks you might for instance create VST Connect, select the channels that you want the
Performer to hear, then right click the Cue (VST Connect) channel in the Control Room Mixer and select "Use current mix levels"
in the "From selected channels" submenu, and the Performer will hear those channels like you hear your mix.
If he or she then wants the guitar a bit lower and vocals a bit more,
you use the cue sends of those channels to adjust his or her headphone
right you find the Performer Monitor. Items in the lower part of this
view (faders etc.) can be edited remotely by the studio engineer as
well as the Performer himself. This is also true for most of the
settings (cogwheel/Performer) so that the Performer can relax and just
do his job just like in a standard local recording situation.
The topmost row (below the record section and the "Monitoring" label)
is to assign hardware inputs and outputs of the Performer channels:
- Master: set the Performer's hardware output (headphones) here.
The interface device is set up in the settings. The Master fader
controls the overall Performer Monitor volume.
- Studio: the return from the studio. Obviously, no port can be assigned here (fixed to "STDIO").
- VSTi: same here, this is fixed to the output of a VST Instrument, should one have been set up (pls. refer to the manual).
- Mic, Instr: set the Performer hardware input ports. This can be
any audio input available. Please note that the one thing that can't be
set remotely is the input gain of the hardware interface, as there is
no standard way to do so. The Performer needs to set up the according
input gain manually, you may guide him or her reading respective
With the PRO version, up to 14 additional audio input channels may
be added. The same rules apply as with the mic/instr. channels.
Note that all those faders merely control what the Performer hears;
none of them have any influence on recording, neither local, nor
The next row features two buttons, enable inserts and mute. You
set up inserts in the lower section "Ins" tab which also features a
global enable button for all (up to four) insert effects.
Further down is a tiny slider which controls the amount of reverb
(as configured in the "Reverb" tab in the lower section) for each
channel separately. Note that compression, reverb, and eq (also below
per channel) are local to the Performer, these effects are not beeing
As for insert fx, see recording below.
Then there are pan, and faders. The very bottom denotes the channel Names, Input channel names can be edited (double-click).
the Performer Monitor resides the Recording section. This controls the
stereo recording on the Studio side. Note that HD recording in the PRO
version is not affected by any of the Performer Monitor or this
recording section, with the notable exception of the stereo mix. All
separate channels are recorded directly from the hardware inputs.
- the Master channel is always recorded (stereo mix).
- the dials control each channel's level in the stereo recording.
- small horizontal faders control the stereo position (pan) of each
channels contribution. You may set these hard left/right in the SE
version and later separate to two mono tracks if you want to record for
instance a singer and guitar played at the same time. With the PRO
version you may just get the HD files later which are automatically
assigned separate tracks then.
- record buttons enable or disable recording to the stereo mix
(and local HD recordings I guess). So you might want to record only the
instrument channel but not the mic channel if that is used only for
- finally, the "FX" buttons allow to set for each channel whether
or not the cahnnel's inserts should be recorded or not. When disabled,
the Performer will still hear the insert effects so to improve his or
her listening experience, yet the signal is recorded without those
Pitfalls and more troubleshooting
Here are some things to be aware of when using VST Connect.
It can not be repeated too often that you are advised to
- use an 'Empty' project and 'Create VST Connect'. This should just work.
- don't try to solve problems blindly poking around everywhere. If you
do nevertheless, make sure to revert changes that you made which didn't
lead to success. An accidently changed item may cause problems not
covered by the 'Repair VST Connect'.
A loose collection of other items
- dropouts: increase 'Remote Latency' in the VST Connect plugin settings (cogwheel).
- disable ASIO Guard (should work now but just in case)
- do not enable channel monitor for Performer tracks/channels
- save CR (Studio) preset when it works
- disable Direct Monitoring
- exit other networking apps (mail, browser, Skype or teamSpeak etc)
- not a jamming tool!
- sample rate: in case of a sample rate mismatch, the Studio sends a
request to the Performer to adjust it. Some Audio Interface can not
change the sample rate programatically; in that rare case, the studio
will repeatedly get a warning and has to advise the Performer to set
the sample rate to that of the studio, or, alternatively, the studio may
change its project sample rate instead (make sure to save the project
- latency issues (delay): check to have Rehearse off and no input monitor on Performer tracks active
- do not activate 'Constrain Delay Compensation' - it will disable
VCON. But make sure to have no latency plugs in the signal path.
- local connections can only be established with the LAN button (PRO Version only)
- additional firewall application (router firewall, user installed
firewall): allow UDP. Usually, there is no need to mess with firewall
settings, port forwarding or the like. This applies only when you have
special firewall or router settings or software.
multiple 'Cue (VST Connect)' (or other) cue channels may have
accidently been created. Just delete all but one of them. The VST
Connec Cue channel can not be created if there are too many cue
- disable 'Cycle' mode, it is not supported well for VST Connect recordings
- You might try to delete VST Connect preferences (assuming Windows on
C:) C:\Users\<me>\AppData\Roaming\Steinberg and there, any of the
VST Connect .ini files that apply.
- The iOS "Studio Pass" app works only with "VST Connect Pro".
- Plugins with latency in the Control Room (or some other places) might
well cause problems with syncing. VST Connect sends playback ahead of
time to the Performer and compensates for the remote delay. If other
plugs with delay are in either path (cue send, return from Performer,
or monitoring Performer) this certainly breaks synchronisation.
- You can get mono if you create a Mono VST Connect Input channel
instead of the default stereo one. So you may go to Devices/VST
Connections/Inputs, delete the VST Connect Input channel, create a new
Mono Input Channel and insert the VST Connect plugin there.
- If Performer uses direct monitoring, you can simply mute his own
channels in the Performer Monitor, only drawback is you can't use
built-in Performer fx properly then.
