Piz MIDI plugin collection

These are intended to be small, useful MIDI processing VST 2.4 plugins, and are available for Windows (32/64-bit), Linux (x86), and Mac OS X (PPC/x86, 32/64-bit), unless otherwise noted. They use the host-provided GUI for easy development. C++ source code is available via Google Code.

Current price: free.

Included Plugins

• midi16CCRouter - Changes up to 16 CCs to 16 other CCs.
• midi2qwerty16 - Use MIDI to trigger fake keystrokes to the focused window.
• midiAlias - Note values are reflected between a "Nyquist Note" and a "Zero Note," similar to the effect of audio sample aliasing.
• midiAudioToCC - Converts audio amplitude to CC messages.
• midiBlackKeyFilter - Separately adjust velocity of black and white keys, and/or send them on different channels.
• midiCCModulator - Use one CC to modulate another CC (or note velocity) in various ways: add/subtract/multiply/etc, plus logic gates (AND, NAND, XNOR, etc).
• midiCCReset - Remembers CC values and sends them out again at selected times.
• midiCCStepper - Quantize CC events by value or in time.
• midiCCToggle - For changing momentary CC buttons into toggles.
• midiChannelize - Transforms everything to the selected channel.
• midiChordHold - Sustains a chord until another one is played.
• midiChordSplit - For splitting polyphonic material to multiple midi channels based on selected note ranges for each voice.
• midiChs_noGUI - Channel filter/changer like energyXT1 "MIDI chs" component.
• midiConverter3 - Change and convert between CC, Channel Pressure, Poly Aftertouch, Program Change, Pitch Bend, NRPN/RPN, Note On/Off, and other messages in various ways.
• midiDelay - Delay notes and/or CCs with feedback.
• midiDuplicateBlocker - Remembers all MIDI message values it gets on each channel, and blocks any repeated values until a different value is received.
• midiExactDelay - Simple delay (no dry signal, no feedback) with flexible and precise delay time.
• midiFingered - Selectively sends standard portamento on/off CC messages to emulate "fingered portamento" for synths that don't have it.
• midiForceToKey - Enforces a scale, and transposes within the scale (optionally based on MIDI notes on a selected channel).
• midiForceToRange - Transposes notes by octave into the selected range.
• midiInvertNotes - "Mirrors" notes centered around the selected note.
• midiKeySplit - Simple keyboard splitter.
• midiKeySplit4 - Four-zone keyboard splitter.
• midiMultiProgramChange - Uses input program change to trigger selected program changes on all channels.
• midiNotchFilter - Isolate, remove, or channelize specific MIDI messages.
• midiNoteGroups - Assign play and/or choke groups to MIDI notes.
• midiNoteMap - Simple 1-to-1 keyboard mapper.
• midiNoteRepeater - Repeats every Nth note a set number of times, or blocks it.
• midiNotesToCC - Converts note number and velocity to CC messages.
• midiNoteToggle - Notes (optionally within a selected range and/or channel) are toggled... play a note once to turn it on, play it again to turn it off.
• midiNRPNConverter - Converts between NRPN/RPN and CC messages, with 16 conversion slots.
• midiOverlappingNoteKiller - Prevents overlapping notes at the same pitch.
• midiPitchBendQuantize - Quantizes pitch bend messages to up to 25 values.
• midiPitchBendToNotes - Changes pitch bend plus note messages into notes at the "bent" pitch (may be useful for using Suzuki QChord with non-multitimbral instruments).
• midiPolyphony - For spreading polyphony across MIDI channels, i.e. if you play 4 notes, each one will go to a different channel. Polyphony per channel can be set from 1 to 16 notes for more flexibility. You can also use it to convert polyphonic input to monophonic output.
• midiProbability - Add probability-based effects to incoming MIDI events, optionally synced to host timeline.
• midiProgramChange - Send Program Change and/or Bank Select messages.
• midiSimpleLFO - One CC LFO with some "simple" options.
• midiScaleChanger - Transposes notes by individual scale degrees and/or globally, to change one scale into another. Among other things, this allows you to play any scale using only the white keys.
• midiSostenuto - Like a piano sostenuto pedal, but for MIDI notes instead of piano dampers.
• midiStrum - Sequentially delays notes of an input chord to simulate strumming.
• midiStuckNoteKiller - Sends note-off messages to end hanging notes when the host stops (for hosts that don't do this themselves).
• midiSwing - Delays and/or offsets velocity of and applies probability to notes (and optionally also CCs) at every other step of a selected note value.
• midiTriggerList - Use one note or CC to trigger up to 8 other notes and/or CCs.
• midiVelocityScaler - Scale/reverse/offset velocity of input notes (Note On and/or Note Off).

Host support

Not all VST hosts support MIDI VST plugins. Most do, some quite well, and others with certain complications.

Renaming a plugin with "fx" in its name with force the plugin to load as a VST effect. By default they load as VST instruments. See pizmidi.ini for more options for configuring plugins globally or per host.
