ModSynthVST is a VST plugin that can run instruments created using the ModSynth Android app within VST supporting host applications on Windows. You can download the plugin for free by clicking "Download File" below:
To run the ModSynthVST you need to setup Java. You can download and install Java from http://www.java.com.
After that, you'll need to unzip the ModSynthVST.zip file into an appropriate directory. The ModSynth.dll within the zip file is the plug-in launcher, the ModSynthVST.jar is the actual plug-in (written in Java) and the .modsynth files are the instruments (programs). All of these files need to be in the same directory for ModSynthVST to run and find instruments.
You can create instruments using the ModSynth Modular Synthesizer on Android and then copy the .modsynth files for those instruments to the directory where ModSynthVST.dll is located. Then, run your VST host application, load the ModSynthVST plug-in within it, and you should be able to find your created instruments within the list of programs selectable for the plugin.
To delete instruments, just delete the .modsynth files.
You can run most instruments except those containing these modules: - Pad -- no pad control is displayed so these instruments can't be used. - PCM -- the wave and soundfont support that this module uses is not available on Windows.
MIDI controls should map to ModSynth sliders as you defined for the ModSynth instrument. Currently there is no mechanism to specify what MIDI channel to use so the ModSynthVST will respond to all channels.
