Powershell Wrapper for Voicemeeter API

This module offers a Powershell interface for the Voicemeeter Remote C API.

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

Tested against

• Basic 1.0.8.8
• Banana 2.0.6.8
• Potato 3.0.2.8

Requirements

• Voicemeeter
• Powershell 5.1+ or Powershell 7.2+

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

Script files

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

Added in v3 you may also use the following entry/exit points:

• Connect-Voicemeeter
• Disconnect-Voicemeeter

Connect-Voicemeeter takes a single parameter Kind.

for example:

$vmr = Connect-Voicemeeter -Kind "potato"
...
Disconnect-Voicemeeter

Through the Shell

One liners should be run through a subshell, you may pipe the Remote object to a script block, for example:

powershell { Get-RemoteBanana | % { $_.strip[0].mute=$true; $_.Logout() } }

You may also save the object returned by a factory function to a local variable, then invoke any commands through the shell, for example:

$vmr = Get-RemoteBanana
$vmr.strip[0].mute=1
$vmr.strip[0].mute
$vmr.Logout()

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

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() }

Config Files

$vmr.Set_Profile(<configname>)

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.

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.

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

Run tests using .\tests\pre-commit.ps1 which accepts the following parameters:

• kind: Run tests of this kind
• tag: Run tests tagged with this marker (currently higher or lower)
• num: Run this number of tests
• log: Write summary log file

Run tests from repository root in a subshell and write logs, like so:

powershell .\tests\pre-commit.ps1 -k "potato" -t "higher" -log
