Piz, more formally known as Insert Piz Here, is a music software project by developer Reuben Vinal that has produced a long-running collection of free MIDI processing VST plugins. The work is hosted at thepiz.org and is most commonly referred to in producer circles as the Piz MIDI suite or pizmidi.

The catalog focuses on small, utility-style tools rather than instruments or full effects. Notable plugins include midiChords (a MIDI chorder that maps single notes to user-defined chords), midiCurve (velocity and CC curve shaping), midiKeyboard, midiMonitor, midiLooper, AudioToCC (converts audio amplitude into MIDI CC messages), and a broader set of small non-GUI utilities such as midi16CCRouter, midiTranspose, midiChordSplit, and midiForceToKey for routing, transposing, splitting, and quantizing MIDI data.

The plugins are written primarily in C++ (with a few older SynthEdit-based builds) and target VST 2.4 across Windows, Linux, and macOS. The source code has been released and is mirrored and maintained by community forks on GitHub, which has kept the suite in circulation among users of hosts like Cantabile, Gig Performer, Renoise, and other DAWs that benefit from lightweight MIDI utilities.

Piz has 3 products cataloged on Equipboard, including Generator Plugins and Virtual Patchbay Plugins. Their gear is featured by 1 artist, with the strongest followings in Rock, Pop, and Metal. Notable users include Jared Dines.
