The interface may not be fancy but this host is extremely complete, with a detailed help. It works in 32 or 64bit, VST2 or VST3. I use it for more than 10 years.

One word:- Reaper. Not freeware, but a fully functional DAW, with a fully-functional, non-expiring demo'(It'll nag you to buy it for 5 seconds on startup, but that's all). I was first drawn to Reaper becuase it was then the ONLY DAW I could find that could deal with multiple concurrent hardware MIDI controllers, each routed through to their own VSTi....

I cannot set audio input device in windows 10. Works fine in win 7. Is it not compatible with win 10? Same problems with Savihost too. I select input port selecting audio device and closes box. Then I open box again and it says "No wave" The problem seems to be with win 10. Can anyone help??

I landed here looking for a better alternative for Microsoft's GS Wavetable Synth. I am a total Noob.I do not find a manual for this software anywhere and I am unable to figure out how to use this software. I am on Windows 7. I want to use the Yamaha Softsynth from https://veg.by/en/projects/syxg50/ It appears the VSTs need a host and this program does that. I dragged and dropped the DLL and I could play the virtual keyboard. But then I need this Synth in a midi player program that I am experimenting with. How do I get it to appear in the my list of Midi devices? Can someone help me out ?

This thing is great... all except that (at least in win 10) it doesn't completely unload everything from ram between "performances".. so after using a bunch of vsts, vsthost hit's the ram ceiling and crashes (im on a tablet with limited rams so). :( - but maybe that's this 'being left behind in ram' issue is the fault of the vsts, no vsthost. not sure.

This is easily the best designed and easiest to use host for VST-instruments. Once you start the program, it is best to hit Ctl-Alt-Del and find vsthost.exe process running there, then set its process priority to REALTIME. Any competing process hogging CPU should be lowered in priority. This can be important for reducing latency.

I have learned more about MIDI with this tool than anything or anywhere else. It gives you the basics in a way that you must learn principles of routing MIDI signals through out MIDI controllers, VST Instruments and effect. Excellent job.

Works flawlessly on Windows 7. I am running Windows 64bit edition but, still able to run 32b dlls. The main thing I like about this host is that it is simple to operate. It isn't bulky and you're able to get in and play by just tweaking a few settings. I am using a Williams Legato digital piano connected to USB as an input.

Simply the best VST host I've found. It just works. Brilliantly. I load up a single instrument VST (usually MrRay73) and a single multi-fx VST and then I can drag and drop any number of other VSTs to trial, either as instruments through my FX VST or as effects using my MrRay. It's so easy to connect and chain and/or disable VSTs. Great utility.

This version here is V.1,54 but HERMANN Seib has done some updating since then, it's now V.1,56 that is available on his own website... Thanx to you Hermann, I whish I had spare money to paypal you some, u greatly deserve it because you made us here a great tool, so easy to use n yet so powerfull in possibilities... Just a little nag so, the connector squares wld do with double their size, so that no need to do chinese eyes to connect things to each others....BUT OVER AMM A BRILLIANT PIECE OF DEVELOPMENT, your sure understand the resolving the complex to offer us the simple n efficient... ALL THE BEST TO YOU MAN...

This one is an awesome little piece of software, indeed. I use it to play guitar with amp plug ins, and drums with Addictive Drums. It basically makes every DDL file feel like it is a stand alone. And there is the "younger" brother SaviHost, that though more limited, it is wonderful as well.

Like this software, makes a lot of sense for hosting plugins, but having some trouble with the audio occasionally becoming distorted, and have to reboot the program. Running Winders 7 on a 64 bit machine. Yes, I downloaded the 64 bit version. Also tried increasing the number of samples. Any thoughts from you wizards out there?

Would be cool if you could just load vst without launching a application, like a right mouse click and that VST loads because the app is running already as a windows process. I imagine it would be used strictly for test and would load a pop up keyboard window.

You can drag and drop the plugin dll on the VSThost icon or in its window to open it.

Not bad , now if it could just look nice. And maybe someway to bring up the plugins full screen (made to fit) one at a time or in any combination. Small difference in audio when switch A/B from direct. What would be neat is to up sample. Am I dreaming ?

Really great software! Compatible with just about every VST I've tried, and the ones that didn't work were broken for most other Hosts as well. Whether you're professional or just a beginner noodling about (which I am the latter) this is a great program for music. Simple and easy to learn.

Very stable. I tested this app and it hosted 99% of the VST plugs i gave it. A little barebones compared to some Hosts but it has a very straight forward interface and it is intuitive enough for new users and capable for advanced users as well.

Anonymous Dec 28 2013

It should work straight after you select the correct midi input device (hardware I mean...). Maybe your vsti require a specific midi channel, or your keyboard is not setup correctly. Here is the manual:http://www.hermannseib.com/documents/VSTHost.pdf
pmh Dec 29 2013
Dec 29 2013
Thanks for replying. I read the manual, and nothing. Then, after much head scratching, I found that under "Devices" - "MIDI" - "MIDI Input Devices" - "Filter Settings" all 16 channels were ticked. Once I cleared all these (click "None") everything now works fine. Not sure why these were all ticked in the first instance, but there you go. This might be one to check for anybody else who cannot get their controller to work.
electronica guru Oct 27 2013

I am a electronic music engineer and teacher, I totally recommend this freeware, learn to use for your practical applications, set up your keyboards for live performances in the save banks... you can switch to each between songs on stage, your settings are saved and when you open your named configuration, even the KNOBS and SLIDERS all the settings on the synth are there, you just play... I record live performance using the WAV recorder, hundreds of riffs from the synths I get here or where ever and I make banks that I archive like LOOPS, then when working in my DAW tracker, I import the WAV files and arrange in my songs, I flip through all the different ones I made prior and select, I build songs this way... I can make hundreds of riff, little measures fast and easy with out having to open and use my DAW, it's hard to just shuffle through VSTi in the DAW (you open one, insert midi track, play, the bounce to tracks, then erase or delete off,-you know the process, with this it's so much easier to make your wav files). With this, you can be a PRO BAND on Audacity by just importing in your recorded wav files...

How do you hook up midi keyboards???
liamcat Oct 27 2013
Oct 27 2013
if you haven't figured out yet, your keyrigs need to have the driver installed on your computer, then in VSTHost, on the command bar, go to devices, look for midi, if your keyboards on hooked up to computer and turn on, the driver for the boards are instal properly, you should see your midi devices name, click on it then click ok. All my keyrigs are USB powered, the ones for stage performance atleast, but a few of my older synths I cant use as controller for this host or any VSTi hosting application like DAW systems. Only the banks in the synth itself can be used. You can use a logitech game controller on this host...LOL, I do live on stage...

liamcat Oct 27 2013
Oct 27 2013
Since I am a guru at midi and electronica... I will tell you... You need to record your guitar live plugged into your tracker DAW, from the guitar to your mic jack... don't USE a pre amp or you will blow out your soundcard, split off on a Y adapter one to mic jack one to pre amp, Audacity does this too, it will record the vibrations from your pick ups just fine, sound sort of like a acoustic...sort of, like how you played your guitar without a amp, after you made your recording, and saved, disabled the record, then add the free AMP PLUG IN on your EFFECTS CHAIN, you can then tweak the amp to sound like your hardware amp if you have any more questions.... hit me up at "liam labelingtheia" on FB, i will answer you and help you...just no spam.

I love THIS-you can set up the tools bars..you can record what vsti then save it to your desk top, record many different synth parts from many vsti save all to the desktop folder (it records as a wav.) then you can open your DAW and insert the wav. files into a audio track, from there you can tweek it, beat mapper, cross fade, what ever you want to do to it. A better way to make your own loops with your midi controller than FL
