     - "Single" version that supports one

       instrument and one stereo channel per instance.

     - The default version that supports kits of 16 instruments

       and 16 output stereo channels per instance.

* Operating System:

     - GNU/Linux (LV2, VST3, Standalone)

     - Windows (LV2, VST3)

* Scale the UI by factor (useful for HiDPI)

## Requirements

In order Geonkick to run and operate correctly there is a need

for standalone:

* GNU/Linux operating system

* Jack server running

for plugin:

 * GNU/Linux or Windows operating system.

 * A host that supports LV2 or VST3 plugin format.

## Build & Install

##### Install dependencies

In order to build Geonkick there is a need to install

the following development packages:

* libsndfile

* RapidJSON

* JACK Audio Connection Kit

* LV2 development library

On Debian, Ubuntu, Ubuntu Studio install:

    apt-get install build-essential cmake libjack-dev libsndfile-dev rapidjson-dev lv2-dev libcairo2-dev

##### Build & install Geonkick

Clone the Geonkick code repository, compile and install.

        copy the source code of the latest release

        mkdir geonkick/build

        cd geonkick/build

        cmake ../

        make

        make install

##### Build Geonkick with VST3 Plugin

Get VST3 SDK than build Geonkick VST3 plugin:

        mkdir geonkick/build

        cd geonkick/build

        cmake -DVST3_SDK_PATH= ../

        make

        make install

##### Building on Windows

To build on Windows, there is a need to install MSYS2/UCRT64 and follow

the same steps as mentioned above.
