PolyHostInterface v3.1.1

👉 A lightweight, portable Windows host for loading, chaining and controlling VST2 and VST3 audio plugins.

PolyHostInterface is a standalone and VST3 plugin host designed for musicians, synthesizer programmers and audio users who want a compact way to load multiple instruments and effects without the overhead of a full DAW. Plugins are organized in tabs, with synths operating in parallel and effects arranged in a serial processing chain. The routing view provides an overview of each loaded plugin and lets you reorder, bypass, mute, solo and select individual tabs.

PolyHostInterface can also operate as a VST3 plugin inside another host. Its 128 host-visible macros can be mapped to parameters of hosted plugins, allowing those parameters to be automated from a DAW. A built-in MIDI Monitor displays notes, CC messages, pitch bend, aftertouch, system messages and other incoming MIDI data, with filtering, copy and export capabilities.

A distinctive feature is Pointer Control, which lets a MIDI controller manipulate the mouse pointer over a plugin interface. MIDI controls can move the pointer horizontally and vertically and adjust the parameter beneath it using scrolling or dragging. Editable Pointer Maps provide reusable jump points for individual plugins, including multiple maps for plugins with different skins, pages or layouts.

The standalone application can record audio to WAV files or MIDI to MID files. Presets can store plugin configurations, and a missing-plugin repair function helps locate moved plugins when loading an existing preset. PolyHostInterface is fully portable, keeping its settings alongside the program instead of using AppData or the Windows Registry.

Changes:
v3.1.1 10-13-26
The VST3 build now produces:
PolyHostInterface.vst3 — existing FX edition, with its identity unchanged.
PolyHostInterface_Synth.vst3 — new instrument edition with a unique bundle ID and plug-in code.
Right-click a loaded tab and select Open Plugin in New Window.
Multiple plug-in GUIs can remain visible simultaneously.
Audio, MIDI, routing, automation and preset state remain unchanged.
Close the detached window or select Return Plugin to PHI to restore it.
Pointer Control is unavailable only while that editor is detached.
Plug-in replacement, reload, tab closure, preset loading and crash quarantine safely close detached editors.
Browser-style drag-out/drag-back was left out for reliability.
