Powershell Wrapper for Voicemeeter API

This wrapper was written in response to a request in the VB-AUDIO discord for a way to invoke commands using Powershell. It is designed to be simple to use but not every feature is added.

For past/future changes to this project refer to: CHANGELOG

Tested against

• Basic 1.0.8.1
• Banana 2.0.6.1
• Potato 3.0.2.1

You may have success with many commands in earlier versions but some commands (example Macrobuttons) were only added to the API in later releases.

Requirements

• Voicemeeter: https://voicemeeter.com/
• Powershell 5.1

Installation

PowerShellGet:

In Powershell as admin:

Install-Module Voicemeeter

In Powershell as current user:

Install-Module -Name Voicemeeter -Scope CurrentUser

You may be asked to install NuGet provider required by PowerShellGet if you don't have it already.

When prompted you will need to accept PSGallery as a trusted repository.

More Info:

• PowerShellGet
• NuGet
• PSGallery

Direct download:

git clone https://github.com/onyx-and-iris/voicemeeter-api-powershell.git

All examples in this readme assume you've installed as a module. If you decide to direct download see alternative instructions.

Use

When you instantiate Remote class you will automatically be logged in. Use a try finally block to ensure you logout at the end of your code.

Import-Module Voicemeeter

try {
    # Run the factory function for required Voicemeeter type
    $vmr = Get-RemoteBanana

    # Set strip and bus params
    $vmr.strip[0].mono = $true
    $vmr.strip[0].mono  '=> $true'
    $vmr.bus[1].mute = $false
    $vmr.bus[1].mute    '=> $false'

    # Set macrobutton with id 4, mode state to 1
    $vmr.button[4].state = $true
    $vmr.button[4].state    '=> $true'
}
finally { $vmr.Logout() }

Voicemeeter factory function can be:

• Get-RemoteBasic
• Get-RemoteBanana
• Get-RemotePotato

There is no bounds checking in this wrapper, meaning if you attempt to set a parameter that does not exist for that version of Voicemeeter the wrapper will throw an error. So make sure what you are settings actually exists.

Strip|Bus

The following strip/bus commands are available:

• mute
• mono
• solo
• A1-A5
• B1-B3
• limit
• gain
• comp
• gate

A,B commands depend on Voicemeeter type.

Macrobuttons

Three modes defined: state, stateonly and trigger.

• State runs associated scripts
• Stateonly does not run associated scripts
• Index range (0, 69)

$vmr.button[3].state = $true

$vmr.button[4].stateonly = $false

$vmr.button[5].trigger = $true

VBAN

• vmr.vban.enable: Toggle VBAN on or off. Accepts a boolean value.

For each vban in/out stream the following parameters are defined:

• on: boolean
• name: string
• ip: string
• port: int from 1024 - 65535
• sr: int (11025, 16000, 22050, 24000, 32000, 44100, 48000, 64000, 88200, 96000)
• channel: int from 1 to 8
• bit: int 16 or 24
• quality: int from 0 to 4
• route: int from 0 to 8

SR, channel and bit are defined as readonly for instreams. Attempting to write to those parameters will throw an error. They are read and write for outstreams.

example:

$vmr.vban.enable = $true

$vmr.vban.instream[0].on = $true
$vmr.vban.instream[2].port = 6990
$vmr.vban.outstream[3].bit = 16

Command

Certain 'special' commands are defined by the API as performing actions rather than setting values.

The following methods are available:

• show
• restart
• shutdown

The following properties are write only and accept boolean values:

• showvbanchat
• lock

example:

$vmr.command.show

$vmr.command.lock = $true

Multiple parameters

Set many strip/bus/macrobutton/vban parameters at once, for Example

Import-Module Voicemeeter

try {
    $vmr = Get-RemoteBanana

    $hash = @{
        strip_0 = @{mute = $true; mono = $true};
        strip_2 = @{mute = $true; mono = $true};
        bus_1 = @{mute = $true; mono = $true};

        button_34 = @{state = $true};
        button_12 = @{trigger = $false};

        vban_instream_3 = @{name = 'streamname'};
        vban_outstream_0 = @{on = $false};
    }

    $vmr.Set_Multi($hash)
}
finally { $vmr.Logout() }

Remote class

Access to lower level Getters and Setters are provided with these functions:

• $vmr.Getter(param): For getting the value of a parameter expected to return a value other than string.
• $vmr.Getter_String(param): For getting the value of any parameter expected to return a string.
• $vmr.Setter(param, value): For setting the value of any parameter.

Access to lower level polling functions are provided with these functions:

• $vmr.PDirty: Returns true if a parameter has been updated.
• $vmr.MDirty: Returns true if a macrobutton has been updated.

example:

$vmr.Getter('Strip[2].Mute')
$vmr.Getter_String('Bus[1].Label')
$vmr.Setter('Strip[4].Label', 'stripname')
$vmr.Setter('Strip[0].Gain', -3.6)

Config Files

$vmr.Set_Profile('config')

You may load config files in psd1 format. An example profile has been included with the package. Remember to save current settings before loading a profile. To test simply rename _profiles directory to profiles. It will be loaded into memory but not set. To set one you may do:

Import-Module Voicemeeter
try {
    $vmr = Get-RemoteBanana
    $vmr.Set_Profile("config")
}
finally { $vmr.Logout() }

will load a config file at profiles/banana/config.psd1 for Voicemeeter Banana.

Run tests

Run tests using .\runall.ps1 which accepts two parameters:

• tag Run tests of this type
• num Run this number of tests

Current test types are 'higher' and 'lower'

Example: .\runall.ps1 -tag 'higher' -num 3

Results will be logged and summary file written.
