What is NanoHost?

Tone2 NanoHost is a free, minimalist host application which can load VST-synths. Furthermore, it can act as a wrapper which converts VST-synthesizers into standalone applications.
This tiny tool works best for live-performance, sound-design, jam-sessions and testing.

What is special about NanoHost?

  • It is free, requires no registration and you are allowed to share it with your friends.
  • It requires no installation. You can run it directly from a USB-stick or CD.
  • There is no plugin-scanning required since a plugin can be loaded directly - no matter where it is located on the hard-disc.
  • Because of low-level code-optimization it offers highest performance and can operate with lower latency than conventional hosts.
  • The GUI refreshes with an extremely high frame-rate (120 Hz). That's why you will experience smoother animations and graphics than with other hosts.
  • NanoHost itself requires nearly no space on the screen. As a result there is more space available for the interface of the VST-plugins.
  • The software is very small. It requires (nearly) no hard-disc space and is loading extremely fast.
  • Unlike conventional hosts the soundcard settings can be configured individually for every single plugin. This allows you to achieve the best possible performance for your VSTs.
  • NanoHost is very easy to use and offers context-sensitive help.


  • It can convert a VST-synth into a standalone-application. You just need to rename NanoHost.exe to the name of the plugin.dll and copy it to the same directory. When you start plugin.exe, the VST-synth is wrapped and loaded automatically.
  • The output of a plugin can be recorded to a wav-file in high quality.
  • NanoHost can create random patches.
  • It offers a soft-clipping algorithm with low distortion and tube-sound.
  • Scrollbars allow you to work also with plugins larger than your screen resolution. It is possible to display also only a part of the plugin's interface.
  • Midi-notes can be transposed and Midi-channels can be filtered. There are several Midi-velocity curves available.
  • Your current sound-bank can be stored and loaded automatically.
  • It is also compatible with very old 32-bit plugins.
  • It does work also with older computers.

I prefer this to Savihost as it is faster and more reliable, it does have it's limitation though, the most apparent it doesn't do VST3, but for just trying out a synth it's good enough. For 32-bit synths I would recommend the Minihost though.

If you're looking for something which can host more than one at a time I recommend the free version of Voltage Modular and use the stand alone as an VST host. Set up a preset with as many VST host modules as you want. It does VST2 and VST3, only 64-bit though.

It is kind of a version of Savihost. A such, it works nearly identical.

Since discussions are disabled on this vst-host, I will put my main critique here:

It forgets its second, third and fourth MIDI Devices from one start to another in the 32-Bit-Incarnation.

With several MIDI Devices, you always have to activate them.

The 64-Bit-Version does not have this problem, but forgets the last path a VST was loaded from, which the 32-Bit-Version doesn't.

Compared to the 32-Bit-Minihost from Tobybear (which is payware, but can be used with a nagscreen without limitations), it doesn't start without a plugin and therefore has no possibility to open a VST from a history (Windows or its own).

For a vst64host it is nice to have it, since several developers are beginning to abandon 32-bit.

But it should be improved for a bit more usability. The aforementioned Minihost has a much bigger feature set.

I use those vsthosts directly on VST dlls to "open with" them, which is the fastest way to test plugins (which don't need installation), and the biggest shortcome of those hosts is that they cannot load a second VST (for example, to test effects), except ashost, which is a bit instable, and Cantabile 2.0 Lite, which is more heavyweight and checks the plugin directory first.

However, since Savihost is already existing and working, I don't quite understand the purpose of Nanohost, except as an advertizing platform for Tone2.
