TRUMSYNT-16 support.

The complete instrument: AU and VST3, all 13 factory presets, the whole signal chain. The download is the demo — there is no separate cut-down build. A license file is what removes the seven-day limit.

Because TRUMSYNT-16 is not your next bread-and-butter drum machine. It is an experimental workshop for making mistakes worth saving. The 13 cover the range of the engine and give you somewhere to start — after that, the sounds worth keeping tend to be the ones you did not mean to make.

On macOS, unzip the download, open Terminal in that folder, and run ./install.sh. It puts the AU and VST3 where your DAW looks for them. Rescan your plug-ins and TRUMSYNT-16 is in the list.

If you would rather not touch a terminal, drag TRUMSYNT-16.component into ~/Library/Audio/Plug-Ins/Components/ and TRUMSYNT-16.vst3 into ~/Library/Audio/Plug-Ins/VST3/ yourself. That is all the script does.

On Windows there is no installer. Extract the zip and copy the whole TRUMSYNT-16.vst3 folder into C:\Program Files\Common Files\VST3\, which is where every VST3 host looks. Windows asks for administrator permission because that folder is shared by all accounts. TRUMSYNT-16.vst3 is a folder and not a file, even though Windows may draw it with a plug-in icon — copy the whole thing. To update, close your DAW and replace the existing TRUMSYNT-16.vst3 folder; presets and license files live in AppData and are not touched. Rescan, and it is in the list.

On macOS, yes. Both the AU and the VST3 are signed with an Apple Developer ID, notarized by Apple, and stapled, so Gatekeeper lets them through without a right-click-Open dance.

The Windows build is not signed. There is no code signing certificate behind it, so Windows has no publisher name to show you and may warn you about the file. Nothing has gone wrong if it does.

What you can check instead is the SHA-256 sum published beside the download. Open PowerShell in the folder you downloaded to and run Get-FileHash <the .zip> -Algorithm SHA256, then compare it with the .sha256.txt file from this site. If the two match, it is byte for byte the file that was built here.

Open its window once. The seven days start the first time you open the plug-in window, and until you do, TRUMSYNT-16 stays silent — including when it loads inside a project you saved earlier. This is trial behaviour only. A licensed copy always makes sound, window open or not.

Seven days from the first time you open the window. After that the plug-in goes quiet and tells you so when you open it. Your projects and presets are untouched — install a license and the sound comes straight back.

Checkout runs from this site. The license is €49 including VAT, and it covers TRUMSYNT-16 1.x.

Waiting costs you nothing: the seven days start when you first open the plug-in window, not when you download. Grab it now and start the clock when you are ready.

After purchase you download TRUMSYNT-16.license from this site. On macOS, put it in ~/Library/Application Support/Liljeholmen DSP/TRUMSYNT-16/; Finder's Go > Go to Folder command takes you straight there. Create the folder if it does not exist. Reopen the plug-in window, or restart your DAW.

On Windows there is no installer to run. Put the file in %APPDATA%\Liljeholmen DSP\TRUMSYNT-16\ — paste that path into the Explorer address bar to get there, or use the button in the plug-in's license message, which opens the folder for you.

The name has to be exactly TRUMSYNT-16.license. If you download it twice your browser saves the second copy as TRUMSYNT-16 (1).license and the plug-in will not find it.

No. No account, no online activation, nothing sent anywhere while you play. The license is a file on your own machine, and TRUMSYNT-16 reads it locally.

macOS 12 or later, Universal, Apple Silicon and Intel, in any AU- or VST3-capable host. On Windows, the build is a 64-bit VST3 for Windows 11.

On a 2021 MacBook Pro (M1 Pro, 16 GB), one instance of the What preset reads 6% on Ableton Live's CPU meter. Ten instances read 13%, twenty read 24%, and fifty read 50% — so after the first, each further instance costs about a percent.

TRUMSYNT-16 is a single-voice instrument built for multi-instance use, so running one per drum is the normal way to work with it.

Yes. It runs on host clock and follows play and stop, with CLOCK MULT from 1/5 to 6× and swing. SEQ RUN is a host automation parameter, so you can start and stop the sequencer from the arrangement, and MIDI CC119 does the same.

It transposes. A note is read against middle C and shifts the oscillators with it, so you can play the drum up and down from a pad or the piano roll. SEQ PITCH ROUTING decides whether that reaches both oscillators, only VCO 2, or neither.

Yes, from 1.1: a 64-bit VST3 for Windows 11, the same instrument and the same 13 presets. There is no AU, because AU is a macOS format.

It is not signed. See the signing question above for what that means when you download it.

TRUMSYNT-16 1.x updates are included and published on this site. Your license file keeps working across them.
