Is it possible to run PowerPoint VBA macros from Powershell?

I want to run a PowerPoint Macro from a PowerShell script. If i try to run an Excel Macro it works, but if i try to run a PowerPoint Macro it says to me: "type must not be byval".

Code:
$ppt = new-object -comobject powerpoint.application
$pres = $ppt.Presentations.Open($pptSourceFilePath)
$tst = @('test')
$pres.Application.Run("TestMain",$tst)
