Plugin loading seems to have gotten much slower since 20.0.4 seems to happen in most betas and where final releases, it gets faster. Thought it had to do with debug code or something. But after 20.0.3 plugins are loading very slow.

VST plugins can be loaded in an effect slot using the slot's down arrow. The VST plugins appear in the effect selector's 'VST Plugins' section (Windows) / 'VST and AU Plugins' section (Mac).

If a VST plugin gets in a bad state somehow you can press the F5 key (Windows) / Command-R (Mac) while the plugin interface is visible. This will save the settings, reload the plugin and load the settings again.

Note: a VST plugin that's installed while MultitrackStudio is running may not be recognised automatically (the plugins are collected only once per session). You can press the F5 key (Windows) / Command-R (Mac) while an effect selector is visible in order to force VST plugins to be rescanned.

Most VST plugins are VST2 plugins, some are VST3. MultitrackStudio supports both formats.

VST2 plugins

Windows: VST2 plugins are .dll files. In the Plugin Manager a folder can be selected where the VST plugins are located. MultitrackStudio looks for VST plugins in this folder and its subfolders.
Mac: VST2 plugins are .vst files. They're located in the user or system Library/Audio/Plug-ins/VST folder.

Plugins that do supply a graphical user interface will be shown in a window with Bypass and Presets buttons. Plugins that do not have their own user interface will be made to look like native MultitrackStudio effects.

Any presets coming with the plugin appear in the Presets menu. The presets can be factory presets (stored in the plugin itself), presets stored in .fxb bank files or presets stored in .fxp files. MultitrackStudio looks for matching .fxb/.fxp files in the folder where the plugin is located, and all of its subfolders.

There are a couple of 'powered' plugins on the market that come with their own dedicated hardware to run on. These kind of plugins are not supported.

Some plugins generate MIDI data. This MIDI output is merged with the data coming from MIDI input devices if the plugin is in a recording audio track and Soft Monitoring is enabled.


Note: bridging is available for Windows only. The Mac version supports 64 bit plugins only.

Both 32 and 64 bit versions of MultitrackStudio support 32 and 64 bit VST plugins. 64 bit Windows is required to run 64 bit plugins.64 bit MultitrackStudio runs 32 bit plugins 'bridged', or 'out-of-process' in computer lingo. Similarly, 32 bit MultitrackStudio runs 64 plugins bridged. This happens automatically.

Bridging plugins has some drawbacks: there's some performance overhead, and you may hear glitches while recording them at low latencies. It's best to use mostly 64 bit plugins with the 64 bit version of MultitrackStudio.

Note: not all VST plugins are happy running bridged. Some seem to work fine running one instance, but weird things happen if you add more instances. Some copy protection mechanisms may fail. Some won't work if UAC (User Account Control) is enabled on Windows Vista and newer.

A bridged plugin that crashes shouldn't tear down MultitrackStudio. You can choose to run a buggy plugin bridged for this reason. The Plugin Manager can be used to force new instances of a plugin to run bridged. The window title bar of a bridged plugin reads 'VST plugin (bridged): name'.

Under the hood
Each bridged plugin appears in the Windows Task Manager as 'MtStudioVSTServer.exe' (32 bit plugin) / 'MtStudioVSTServer64.exe' (64 bit plugin).

Customizing the VST folder

On Windows the Plugin Manager allows for specifying one VST folder. On Mac there are two default VST folders, and you can specify an additional one in the Plugin Manager. If you need more flexibility you can place an MtStudioLinks.txt file in the VST folder, a folder that's included by an MtStudioLinks.txt file or any of the subfolders. MtStudioLinks.txt must be a plain text file. NotePad (Windows) / TextEdit (Mac) can be used to create/edit such files.

This example file demonstrates the options:

The first line includes the OtherFolder folder. The second line includes the TheReverb plugin. The third line excludes the SamplesDir subfolder, this can be useful if folders with huge amounts of samples slow down plugin scanning. The last line excludes the BuggyPlugin plugin.

Tip: you can press the F5 key (Windows) / Command-R (Mac) while an effect selector is visible in order to force VST plugins to be rescanned.

VST3 plugins

Windows: VST3 plugins are .vst3 files. 64 bit plugins are located in the C:Program FilesCommon FilesVST3 folder. 32 bit plugins are located in the C:Program FilesCommon FilesVST3 (if your Windows version is 32 bits), or the C:Program Files (x86)Common FilesVST3 folder (64 bits Windows version). There's no bridging for VST3 plugins, so 64 bits MultitrackStudio can only use 64 bits plugins and 32 bits MultitrackStudio can only use 32 bits plugins.

Mac: VST3 plugins are .vst3 files. They're located in the user or system Library/Audio/Plug-ins/VST3 folder.

You can use MtStudioLinks.txt files to exclude files or folders (see the VST2 description). Including files or folders isn't possible.

Any presets coming with the plugin appear in the Presets menu. The presets can be stored in the plugin itself, or they can be .vstpreset files in one of these folders:

Below are steps users can follow to help speed up a computer or determine why a computer is running slow. It should be noted that this page only covers an overall slow computer and not a computer that starts slow or has a slow Internet connection. To diagnose those issues, visit the following pages:


If your computer has not been rebooted recently, make sure to reboot it before following any of the steps below. Rebooting the computer can fix many problems and is an easy first step.

Background programs

Why Is My Vst Plugin Running Slow How To

One of the most common reasons for a slow computer is programs running in the background. Remove or disable any TSRs and startup programs that automatically start each time the computer boots.


To see what programs are running in the background and how much memory and CPU they are using, open Task Manager. If you are running Windows 7 or higher, run Resmon to get a better understanding of how your computer resources are used.

If you have an antivirus scanner on the computer, spyware protection program, or another security utility, make sure it's not scanning your computer in the background. If a scan is in progress, it decreases the overall performance of your computer. If this is the case, allow the scan to complete, and the computer's performance should improve.

Delete temp files

As a computer runs programs, temporary files are stored on the hard drive. Deleting these temp files help improve computer performance.

Windows computers

First, we suggest using the Windows Disk Cleanup utility to delete temporary files and other files no longer needed on the computer.

Unfortunately, the Disk Cleanup may not delete every file in the temp directory. Therefore, we also suggest deleting temporary files manually.

  1. Open the Start menu or and press the Windows key, then type %temp% in the Search field.

In Windows XP and prior, click the Run option in the Start menu and enter %temp% in the Run field.

  1. Press Enter and a Temp folder should open.
  2. You can delete all files found in this folder and, if any files are in use and cannot be deleted, they can be skipped.

Free hard drive space

Verify that there is at least 200-500MB of free hard drive space. This available space allows the computer to have room for the swap file to increase in size and give room for temporary files.

Bad, corrupted or fragmented hard drive

Check the hard drive for errors

On a Windows computer, run ScanDisk, chkdsk, or something equivalent to verify there is nothing physically wrong with the computer's hard drive.

On a macOS computer, access the Disk Utility program, and use the First Aid option to check the hard drive for errors. To open Disk Utility:

  1. Click the Launchpad icon on the dock.
  2. Open the Other folder.
  3. Click Disk Utility to open the program.

Make sure hard drive is not fragmented

Run Defrag to help ensure that data is arranged in the best possible order.

Test hard drive

Use other software tools to test the hard drive for any errors by looking at the SMART of the drive.

Scan for viruses

If your computer is infected with one or more viruses, it may run more slowly. If your computer doesn't have an antivirus program installed, run Trend Micro's free Housecall online utility to scan and remove viruses on your computer. We also recommend you install an antivirus program for active protection against viruses.

Scan for malware

Today, spyware and other malware is a big cause of many computer problems, including slower performance. Even if an antivirus scanner is installed on the computer, we recommend running a malware scan as well. Use the free version of Malwarebytes to scan your computer for malware.

Hardware conflicts

Verify that the Device Manager has no conflicts. If any exist, resolve these issues as they could be causing your problem.

Update the operating system

To update a computer running Microsoft Windows, run Windows Update.

To update a macOS computer, run Software Update. To upgrade the operating system, use the App Store.

Disable browser plug-ins

If your computer runs especially slow when you're using your web browser, considering disabling any browser plug-ins, add-ons, or extensions.

Update your drivers

Make sure you have the latest drivers for your computer hardware, especially the latest video drivers. Having out-of-date drivers can cause an assortment of issues, including slow performance.

Reboot the computer again

After making any of the changes above, reboot your machine.

Run a registry cleaner


If you have a Mac computer, skip this section, as there is no registry in macOS.

We usually do not recommend registry cleaners. However, if you followed all the steps above and your computer is still slow, try running a registry cleaner on the computer.

Memory upgrade

If you have had your computer for more than two years, you may need more memory. Today, we suggest computers have a minimum of 2 GB of memory (RAM) for a 32-bit system and 4 GB for a 64-bit system. By having enough memory for programs to run within memory, your computer doesn't need to swap information stored in memory to the swap file. If the hard drive light is continuously active, it's an indication the computer is frequently swapping information between your memory and hard drive.

Hard drive upgrade

One of the biggest bottlenecks of a computer is the hard disk drive. Upgrading from a standard hard drive to a Solid State Drive (SSD) drastically improves the computer's performance.

Computer or processor is overheating

Make sure your computer and processor is not overheating. Excessive heat can cause a decrease in the computer's performance because most operating systems automatically reduce the speed of the processor to help compensate for heat-related issues.

Dust, dirt, and hair can also constrict proper airflow inside your computer, which causes a computer to overheat. Make sure your computer case is clean, and that the fans are not obstructed.

Increase or upgrade the processor speed

Increasing the speed of the processor (CPU) can improve your computer's performance. There are two options for increasing processor speed: overclocking or upgrading.

Overclocking a processor means increasing its speed beyond what it's designed to run stably. While overclocking can increase the processor speed, the increase is often not very significant, resulting in maybe a 10% or 20% speed increase at most. Furthermore, the processor itself must be capable of being overclocked. You would need to find the specifications for the processor in your computer to determine if it can be overclocked. An overclocked processor generates more heat, thus requiring a more powerful heat sink and fan to pull the excess heat away from the processor.

A safer alternative to overclocking is upgrading the processor in your computer. You would need to get the specifications for your motherboard to determine what type of newer processor may be used in it. You can then install the new processor in place of the existing processor.

Erase computer and start over

If none of the solutions above resolve your issues, another option is to reinstall the operating system, or you can erase everything and start over.

Erasing everything on your computer and reinstalling the operating system can increase performance by getting rid of old software or drivers. Installing a fresh copy of macOS or Windows, software programs, and the latest drivers help verify there are no software related issues causing your computer to be slow.

Hardware issues

Finally, if your computer is still slow after trying the above recommendations, there's likely a more serious hardware related issue (e.g., failing component). Examples of failing hardware could include the hard drive, CPU, RAM, motherboard, or other components.

You can run hardware diagnostic tests using the Ultimate Boot CD (UBCD) utility. This utility provides information on whether or not your computer has a bad piece of hardware.

Old computer

If your computer is more than five years old, it performs slower than a new one. As more advanced software programs are released, they are optimized to run more efficiently on newer computers. Older computers are not able to run these new programs as well, which causes them to perform more slowly. Furthermore, new software tends to be more demanding in general, which is another problem for old hardware. We recommend you consider purchasing a new computer or upgrading your current one.
