1-1. Recommended Environment

Certain environmental requirements must be met to have an enjoyable session on SYNCROOM. Before using SYNCROOM, please prepare the following equipment and environment.

• A device that can use SYNCROOM (a device with a compatible OS)
• Audio interface (for Windows, one that supports ASIO drivers)
• Broadband environment such as optic fiber (wired internet connection)

1-2. Communication Environment

① With SYNCROOM, it is important to not simply have a fast communication speed (capable of large-space communication per second), but to be able to communicate stably in smaller time units.

② Even if you contract with the same provider and the same service, connection status varies depending on the area and time of use, so it is difficult to define "the correct line setup". If the line is congested, it may happen that you cannot connect to the room, or there will be greater latency.

③ In SYNCROOM audio communication, user terminals communicate directly with each other without going through a server (P2P connection). Audio communication may be affected depending on the line status of the other users.

④ Communication is often unstable with a wireless connection, and the latency increases, so use a wired connection in order to establish a session.
*Note that even with a wired internet connection, if the cable is an old standard, it may not be very fast.

⑤ If you are using IPv4-as-a-Service, connection with the other users may be affected depending on the characteristics of the service. Also see the FAQ "Can SYNCROOM be used with IPv4-as-a-Service network service?".

• If a blocked user tries to enter a room you have created, they will automatically be forced to exit the room.

Click “Unblock this user” on the blocked user’s profile to unblock them.

7-1. Basic Settings

• To reduce latency when inputting and outputting audio to and from your computer, if using Windows you will need an ASIO driver-compatible audio interface. Install and use an ASIO driver suitable that is compatible with the audio interface you are using. If using a Mac, use the standard Core Audio audio driver. Lower the ASIO or Core Audio buffer size so that clipping does not occur. However, this will also impact the performance of your audio interface and computer.
• For example, if using speakers as monitors, it will take about 3 milliseconds* for sound that is 1 meter away to reach your ears. Using headphones will reduce the latency in sound output from other users.

  Note: Wireless headphones have significant latency, so these are not recommended.
  *I millisecond = 1/1,000th of a second

• SYNCROOM’s sound quality settings will have little impact on your connection speed. Therefore, normally keep it set it to “High sound quality” if possible to ensure a more enjoyable session. If you cannot connect due to insufficient network bandwidth, use a lower sound quality setting.

7-2. Audio Device Settings

You can check your audio input and output by clicking “Test” under “Input” and “Speaker”. Configure your audio device settings while testing them.

If using Windows, select one of the following under “Audio device”.

• ASIO
• WASAPI shared mode
• WASAPI exclusive mode
• DirectSound
• VST mode

Ranked in terms of sound quality and latency, ASIO is generally the best, followed by WASAPI exclusive mode, WASAPI shared mode, and finally DirectSound. For a more enjoyable session, we recommend using ASIO with SYNCROOM.

If using a Mac, you can choose between Core Audio or VST mode. Under normal circumstances, you should select Core Audio.

Note: VST mode should be selected if using SYNCROOM as a VST plug-in on a DAW or other host application.

7-2-1. If You Selected ASIO (Windows)

• ❶ Audio device

  Select “ASIO” in audio interface and then select the name of the ASIO device you will use in the Input/Output field.
  *Installing an ASIO driver compatible with the audio interface you are using will allow you to select “ASIO”.

• ❷ Sampling rate

  Set the sampling rate to the sampling rate of the audio interface you will use. SYNCROOM supports 44100Hz (44.1kHz) and 48000Hz (48kHz) sampling rates. If the sampling rate of your audio interface does not match the sampling rate selected in Settings, SYNCROOM will not work. Some types of audio interfaces allow you to change the sampling rate. If your interface is set to 96kHz or 192kHz, change it to SYNCROOM-supported 44.1kHz or 48kHz.

• ❸ Buffer size

  Buffer size can be set in the control panel If you set the buffer size as low as possible (we recommend 64-128 samples or 2-4 milliseconds), you will have less latency and a more enjoyable session. If you hear clipping with this setting, increase the buffer size little by little until you no longer hear it.

• ❹ Monitor input

  Configure your audio input monitoring settings. You can select from three types: “Do not monitor”, “Monitor (with latency)”, and “Monitor (without latency)”. As long as there is no significant latency, we recommend “Monitor (with latency)” to make it easier to sync up with other musicians. For details, see “Is there a trick to using SYNCROOM enjoyably?” in the FAQ.

• ❺ Channel settings
  • Input in stereo
    Check “Handle as stereo” to handle the selected input channels as stereo. Use this when playing an instrument with stereo output such as a synthesizer.
  • Extension input channel
    You can use this if you have three or more input channels on your audio interface. Use it if you want to talk or sing while playing an instrument with stereo outputs such as a synthesizer.
  • Output channels
    Set the output channels of your audio interface.

7-2-2. If You Selected “WASAPI shared mode” or “WASAPI exclusive mode” (Windows)

There are two WASAPI modes: WASAPI shared mode and WASAPI shared mode. They have the following features:

• WASAPI shared mode
  This has a higher latency than WASAPI exclusive mode. You will be able to use SYNCROOM at the same time as other applications. (Other applications you are using at the same time will also produce sound.)
• WASAPI exclusive mode
  This has a lower latency than WASAPI shared mode. When using SYNCROOM, you will not be able to produce sound from other applications.

• ❶ Audio device

  No specific setting is required in either mode. However, you should select the devices you will use if you are using multiple audio devices such as internal speakers and a USB headset. If “--” appears for your input or output device, you will not be able to open the audio device. Press microphone or headphones to open the device.

• ❷ Sampling rate

  You can only choose a sampling rate of 44100Hz with WASAPI shared mode, but you can choose 44100Hz or 48000Hz with WASAPI exclusive mode.

• ❸ Buffer size

  We recommend a buffer size of 512 in WASAPI shared mode and 192 in WASAPI exclusive mode, but if clipping occurs, increasing the buffer size may solve the problem.

• ❹ With WASAPI, you cannot configure the “Monitor input” or “Channel” settings.

7-2-3. If You Selected DirectSound (Windows)

You cannot select or change any of the audio device settings if you select DirectSound. The sampling rate will automatically be set to 44100Hz and buffer size to 20 milliseconds.

7-2-4. If You Selected Core Audio (Mac)

• ❶ Audio device

  Select the input and output devices you will use. If using an external audio interface, in general we recommend setting the same device for input and output. (See “The sound is distorted” in the FAQ).

• ❷ Sampling rate

  SYNCROOM supports 44100Hz (44.1kHz) and 48000Hz (48kHz) sampling rates. If the sampling rate of your audio device does not match the sampling rate you selected in the audio device settings, SYNCROOM will not work. Some types of audio interfaces allow you to switch the sampling rate. If your interface is set to 96kHz or 192kHz, change it to SYNCROOM-supported 44.1kHz or 48kHz.

• ❸ Buffer size

  Select as low of a buffer size as possible. This will keep latency low and allow you to have an enjoyable session. If there is noise in the audio, increase the buffer size little by little until the noise is gone.

• ❹ Monitor input

  Configure your audio input monitoring settings. You can select from three types: “Do not monitor”, “Monitor (with latency)”, and “Monitor (without latency)”. To minimize latency, we recommend “Monitor (with latency)”. For details, see “Is there a trick to using SYNCROOM enjoyably?” in the FAQ.

• ❺ Channel settings

  Select the input channels of your audio interface.

  • Handle as stereo
    Check “Input in stereo” to handle the selected input channels as stereo. Use this when playing an instrument with stereo output such as a synthesizer.
  • Extension input channel
    You can use this if you have three or more input channels on your audio interface. Use it if you want to talk or sing while playing an instrument with stereo outputs such as a synthesizer.
  • Output channels
    Set the output channels of your audio interface.

7-3. Audio Data Interpolation Processing Settings

The “Enable audio data interpolation processing” function is for stabilizing the reception of audio data. It is enabled by default, but depending on your system environment, disabling it may solve problems such as distorted audio.

7-4. Basic Sound Quality Settings

In “Basic Sound Quality Settings”, you can set the sound quality of audio data transmitted between you and other members. You can make approximate changes to the sound quality by selecting “High sound quality”, “Standard”, or “Prioritize bandwidth” on the left side of the figure below.

If you select “Prioritize sound quality”, since high sound quality requires more network bandwidth, the sound may cut off or latency may increase if your connection lacks sufficient bandwidth. If this happens, lower the sound quality by selecting “Standard” or “Prioritize bandwidth”. You can also make more detailed adjustments to sound quality by changing the settings on the right.

7-5. General Settings

You can configure the following settings in the “General” tab.

7-5-1. MIDI Control Settings

SYNCROOM allows you to control the app from an external device. You can control the following with MIDI:

7-5-2. Alert Sound Settings

Note: “Allow data transmission” is checked by default.

7-6. Environment Test

Note: The results of the environment test do not guarantee that SYNCROOM will work. Connectivity and stability will differ depending on the time of day and other connected users, so use this to check your own system.

7-6-1. Performing an Environment Test

When you open the “Environment test” tab, it will first check your internet connection. When it has finished checking, the following window will appear.

Click the “Start check” button to start measuring. If you click the “Cancel” button while it is measuring, you will be redirected back to the previous window.

7-6-2. Confirming Results

Once measurement has been completed, the results will appear as follows. Be sure to check the details. If you click the “Remeasure” button on the bottom, you will be redirected back to the window before the “Start check” window so you can remeasure all the items from the beginning.

The following is an explanation of each measurement result category.

• ❶ IPv6 support status

  This checks if your connection supports IPv6 communication. Although SYNCROOM can be used even if your connection does not support IPv6, we recommend using an IPv6 IPoE connection with SYNCROOM.

• ❷ Internet line type

  This determines your connection and router type. If there is a connectivity issue with SYNCROOM, an explanation will be displayed under “Type Code”.
  Note: Depending on your system environment, the results may differ depending on the situation even with the same connection. This is only a guide. Connectivity with SYNCROOM will also differ depending on the other connected users and time of day. Also see the following in the FAQ.

  “Which connection can I use?”
  “What is IPv6/IPv6 IPoE?”
  “Unable to connect”.

  Type code:
  Type code is a notation method unique to Yamaha. Currently there are 12 types: A to C, A6 to C6, AU to CU, and AU6 to CU6.

  • A to C: Indicates the characteristics of the connection/router. If it is A or B, there will be no problems connecting with SYNCROOM in most cases.
  • U: Indicates whether port mapping by UPnP can be used. If your connection supports UPnP, connectivity with IPv4 will be improved.
  • 6: Indicates whether IPv6 is supported. If the other users’ connections also support IPv6, you will connect with IPv6.
• ❸ Connection status

  This measures the latency of communication with the test server and displays the result. Use this only as a guide, as it may vary depending on the time of day and other factors.

• ❹ Audio Device

  This checks the type of audio device you selected and its operational stability. You will need to reduce the buffer size for real-time sessions, but if it indicates that there are stability problems, increase the buffer size slightly and check again. Also see the following in the FAQ.
  “I heard that the ASIO driver is recommended for Windows. What is the ASIO driver?”
  “How should I set the ASIO driver / WASAPI?”
  “The sound is distorted”.

• ❺ CPU Performance

  This measures the processing speed of the CPU. If it seems there will be problems with running SYNCROOM, an explanation will be given on the screen.

8-1. About the VST Linkage Function

Using VST plug-ins allows you to work in linked to DAWs and the like.
When SYNCROOM is started normally, it exchanges audio directly with the audio interface. When working linked with VST, SYNCROOM's audio communicates with your DAW or other VST host application via VST plug-ins.

SYNCROOM Audio Flow

The VST plug-in itself does not have SYNCROOM functions, and only exchanges audio with the SYNCROOM app itself. The audio input to the VST plug-in is sent as input to SYNCROOM, and the audio output from SYNCROOM (monitoring sound and each member's audio mixed) is returned as output of the VST plug-in.
SYNCROOM starts automatically when you use VST plug-ins in your DAW. If you start SYNCROOM again after that, if the VST plug-in is inserted, it will automatically be in the VST linked state.

• When working with VST, more resources such as CPU and memory will be used than when SYNCROOM is operating alone. Depending on the performance of your PC, there may be restrictions on which VST instruments can be used simultaneously.
• The attached VST plug-in may not be compatible with all DAWs (VST host applications).
• Depending on the DAW, the display of SYNCROOM's delay time may be incorrect, but basically VST mode will not make the delay shorter than SYNCROOM alone.

8-2. Installing VST Plug-ins

First, download SYNCROOM, extract the files and install the application.
Copy the files in the "VSTPlugins" folder in the compressed file (syncroom_vst_bridge2.vst3 or syncroom_vst_bridge_sub_multiout2.vst3) to the VST plug-in folder used in your DAW.
For example, for Cubase on Windows it would be C:\Program Files\Steinberg\VSTPlugins (depending on where it was installed).

*SYNCROOM Ver. 2.0.0 and later are compatible with VST3 plug-ins.

Each plugin has the following functions.

• syncroom_vst_bridge2
  Works as a VST FX plug-in (effect plug-in).
  When you use this, SYNCROOM will start as "VST collaboration", the audio input to this plug-in will be sent as the input of SYNCROOM. The output from SYNCROOM (mixed monitor sound and each member's audio) is returned as the output of the VST plug-in.
• syncroom_vst_bridge_sub_multiout2
  Works as a VSTi plug-in (instrument plug-in) and is used when you want to take output from SYNCROOM with multiple outputs.
  It cannot be used alone and must be used together with syncroom_vst_bridge2. It has multiple output channels, with the monitor sound and the sound from the connected members output separately.

If you are using Cubase 8 or later and ASIO-Guard is enabled, the output sound may be strange and not output correctly. In this case, disable ASIO-Guard for syncroom_vst_bridge2 and syncroom_vst_bridge_sub_multiout2 by following the steps below. The following steps are explained in Cubase 10.5.
From the menu, select Studio > VST Plugin Manager.
Click the "VST Instruments" tab.
Click the bottom left "i" button (show plugin info), then click syncroom_vst_bridge_sub_multiout2.
Click the part of "ASIO-Guard" that says "Enabled" and switch it to "Disabled".

8-3. Examples of Using VST Plug-ins

The following is a specific usage example in Cubase 10.5. The explanation below is for Windows, but the basics are the same for macOS.
*Cubase Pro is necessary to record multi-output audio separately, using syncroom_vst_bridge_sub_multiout2. Multi-output is possible with Cubase Elements, or the like, but individual recording is not possible. For specific procedures, see 8-3-4. Using as Multi-outputs.

8-3-1. Using in Combination with VST Instruments

First, add an instrument track and load the VST instrument you want to use (in this example, we will explain using Groove Agent SE).

Click on "Audio Insert" and a list of effects will appear. Select syncroom_vst_bridge2 from this list.
*VST3 plugin is displayed under the OnlyRT category.

SYNCROOM will startup automatically. In this state, the audio from the instrument will be sent to SYNCROOM, and the audio from SYNCROOM will be output from the track.

While linked with the VST plug-in, "VST" icon is displayed on top of the screen.
Launching SYNCROOM while VST plug-ins are running will cause it to automatically enter VST mode.

8-3-2. Using Audio Inputted from a Microphone or Other Device

You can use input voice from your audio interface by enabling track monitoring as shown below.
*If the audio interface you are using has a direct monitoring function, set it to OFF (to avoid duplicate sounds).

Add an Audio track.

Click the monitoring button (speaker icon) (the monitoring button is located to the right of the record button "●").
This will allow incoming audio from your audio interface to be output from the track.

Click "Inserts" to call syncroom_vst_bridge2. Now the input voice from the audio interface will be sent to SYNCROOM.

You can also perform sessions with voice with effects applied by inserting various VST effects (such as reverb or amp simulator) before SYNCROOM.

8-3-3. Simultaneously Using Audio Inputted from a Microphone and VST Instrument

In Cubase, you can group audio from multiple tracks by using a function called "Group Channel". Specifically, the steps are as follows.

Add a "group track".

Next, add an Audio track.

As in 8-3-2 above, click the "monitoring button" to enable inputs such as the microphone.
Click the button labeled "e" (edit channel settings) for the added audio track.

The channel setting screen will be displayed. Click on the right side of the track name (such as "Audio 01") in the upper left of the screen and select the created group channel (Group-Group1).

Then add an instrument track and load the VST instrument you want to use. After that, follow the same steps as the audio tracks described above to set the output of the VST instrument's track to the same group channel (Group-Group1).

Select the "Group1" track of the group channel and call "syncroom_vst_bridge2" from "Inserts" in the inspector.

Now both the input voice from the audio interface and the audio from your VST instrument will be sent to SYNCROOM.

8-3-4. Using as Multi-outputs

First, set the above 8-3-1.

Click “Studio” in the Cubase menu and select “VST Instruments”.

From the "VST Instruments" screen, click "Rack".

A list of instruments will be displayed. Select syncroom_vst_bridge_sub_multiout2.

If you see a dialog asking whether you want to create a MIDI track, then you can click Cancel.

From the "VST Instruments" screen, click the "Enable Outputs" button and select "All Outputs".

You will see multiple stereo tracks on the screen. They correspond to monitor output, the Each locations of connected members, and the room connection audio (audio that reflects the pan pot on the SYNCROOM screen is output).

The multi-output settings are now complete, but since the original track (the track with the syncroom_vst_bridge2 inserted) and the output voice will be duplicated, so mute this.

If you are using Cubase Pro, you can record each part individually by combining it with the group channel function.
Create a group track and set the channel output of the instrument you want to record to that group track.

Create an Audio track for recording. Set the Audio track's input to the group track you want to record.
