SAVIHost is a derivative version of VSTHost that can be used to make any VST Effect or VSTi run like a standalone application.

This offers two major advantages:

  1. Effect or VSTi can be used (tested, checked or tried) easily and directly without the need or search for another host.
  2. Effect or VSTi can be distributed to be tested in a temporary directory without the need of the presence of another host or to search for a dedicated VSTPlugIns-subdirectory. The VSTi-dll can still be used within other hosts like Cubase, Sonar etc. when copied to that host's VSTPlugins-subdirectory.

For use just rename SAVIHost.exe to the corresponding VSTi.dll e.g. if there is abc123.dll rename SAVIHost.exe to abc123.exe and this will run the VSTi.

Separate versions for VST 2, VST Module Architecture, and VST3 are available in 32- and 64-bit versions.

It's crazy that SAVI host hasn't got a review yet.

This is one of the best free tools around, like a Swiss Army knife, it's perfect to quickly check out a VST instrument without the need for a DAW, or to use a VST instrument without a DAW.

Here's basically what one needs to do:

1: Download SAVI host
2: Unzip/Unrar downloaded file
3: Place unpacked "SAVI.exe" file in same folder as "X-VST.dll"
4: Rename "SAVI.exe" to exactly the same name as "X-VST.dll", in other words = "X-VST.exe"
5: Double click renamed "X-VST.exe" to start instrument

The programme got lots of features, like recording of perfomances that can be saved as wav files.

MIDI is supported, and have worked well with my interfaces. The latest version of the host allows up to 3 MIDI controllers to be connected at once, so you can for instance use your big 76 key MIDI controller for playing, and add to that a little AKAI mini for knob twiddling (via right-click MIDI learn). Both will work at the same time.

But there is even no need for a MIDI keyboard, in SAVI host one can use the regular computer keyboard as a two octave piano keyboard. This is a programme that just keeps on giving!

I agree completely and use the 32 and 64 bit versions all the time. Guilty of ingratitude, this gives me an opportunity to say, "Thank you, Hermann Seib!"

4 September 2012 at 8:43pm

Absolutely - this thing is invaluable and I use it all the time. Three cheers for Hermann Seib!'

7 September 2012 at 4:29pm

For people making / debugging plugins this can be very useful for quick trying-out. Especially when combined with command-line shortcuts!

This is an excellent tool ! Thanks a lot Mr Seib !

I have Savihost running GSI's VB3 organ on my windows XP notebook. I am using a MIDI keyboard and a Korg Nanokontrol as controllers, each plugged into their own usb ports on the notebook. Savihost will only let me use one MIDI controller... is there a way around this??

Use a recent version, which allows up to 3 MIDI inputs.

Thanks, I found VSTI Host V1.41. Allows 3 inputs and works perfect..

The KVR field "Price" should be not only "Free" but "Free (donationware)". There is a nag screen at each start.

Hey I'm trying to rename savihost to open a Synth program called TX16Wx and the files called TX16Wx AU 2.4.2g so if anyone could let me know what I should rename the savihost file as in order to open the program it'd be much appreciated ! Thanks.

Hi have sent some money via paypal last week and an email to Mr Seib (office@hermannseib.com and him@hermannseib.com) in order to ask the removal of the "nag screen" in Savi host does someone know how to contact him using another email please ?
since I did not get any answer yet and I have no access to his forum as it is apparently not possible to register anymore.

Any suggestions are welcome.
Many thanks in advance for your help.

Cheers, Eric.

I am answering to my own post... Mr Seib just replied me today, so everything is fine now.
Cheers, eric.

I guess I'm too stupid to set this thing up. I keep getting errors. Like side by side comparison failed.

What is the 'modular' version?
