How to Install Loudstakk MIDI Grooves into Steven Slate Drums 5 (SSD5)

Including how to manually convert folders into SSD-compatible .lib, .prt, and .sng formats.

SSD5 doesn’t read third-party MIDI the same way Toontrack instruments do. It requires a very specific folder structure — and in some cases, special file extensions — to make grooves show up properly in its internal browser.

Here’s the complete workflow based on real customer tickets and the official SSD behavior.

---

1. Unzip Your Loudstakk MIDI Pack

After downloading your pack, you’ll have a folder like:

• Loudstakk Thrash Metal MIDI Pack

• Loudstakk Doom Metal MIDI Pack, etc.

Inside that folder are the actual .mid files.
The folder structure is correct — no additional files are missing.

2. Try the Standard Import Method First (Recommended)

SSD5 has an internal option to import third-party MIDI without needing to alter files.

How to Do It:

1. Open Steven Slate Drums 5

2. Navigate to the Grooves tab

3. In the left column, right-click inside the User MIDI area

4. Select Import MIDI Library

5. Choose the folder containing your Loudstakk .mid files

6. SSD5 will scan them and build its own internal library structure

If SSD5 accepts the import, your Loudstakk grooves will now show up under User Libraries.

Some versions of SSD5 handle this perfectly.
Others don’t — especially older builds — which brings us to the manual method.

3. Manually Convert Loudstakk Folders into SSD5 MIDI Libraries

(Advanced method — only needed if SSD won’t recognize your MIDI.)

SSD5 uses folder extensions to classify and index MIDI libraries.
To force SSD5 to read your Loudstakk folder as a native library, you can add SSD’s expected suffixes:

Required Extensions

• .lib — Identifies a library

• .sng — Song folders

• .prt — Parts/sections

SSD5 doesn’t care what the folder name is — it only cares about the ending.

How to Convert the Folder:

1. Locate your Loudstakk MIDI folder
   Example:
   Loudstakk Thrash Metal MIDI Pack

2. Rename the folder by adding .lib at the end:
   Loudstakk Thrash Metal MIDI Pack.lib

3. Inside that folder, create subfolders for organizational purposes, e.g.:

   • Grooves.sng

   • Fills.sng

   • Parts.prt (optional)

4. Place your .mid files into those subfolders

5. Restart SSD5

6. SSD5 will now index those folders as proper libraries

Why This Works

SSD5’s browser was designed around Slate’s internal library formats.
By adding the correct suffixes, you’re telling SSD5:

“This folder is a library. These are songs. These are parts.”

SSD5 will now treat the folder exactly like its built-in MIDI.

4. Folder Structure Example (Works Reliably)

This is the clean SSD-compatible structure many users prefer.

5. Important Notes

✔️ Loudstakk does not provide .lib, .prt, or .sng libraries

These extensions are part of SSD5’s proprietary structure and must be added manually.

✔️ This is a “use at your own risk” method

SSD5 updates sometimes change how folder suffixes are handled.

✔️ If SSD5 won’t preview MIDI correctly

Use your DAW’s built-in MIDI preview instead — it’s always accurate.

6. Summary

EZdrummer/Superior = plug-and-play
SSD5 = requires manual setup

The fastest workflow is simply importing the folder via Import MIDI Library.
If SSD5 refuses to index the files, rename folders with SSD’s expected extensions:

• .lib

• .sng

• .prt

Once done, SSD5 recognizes the pack as a native-style library and everything appears in the Grooves tab.
