Semana do MIDI: Ripchord is a free MIDI plugin for creating and remixing chord progressions.







Ripchord is a free MIDI plugin for creating and remixing chord progressions. You can create custom chord presets from scratch, load expansion packs, or import any MIDI file that contains chords and Ripchord will automatically create a preset from it. Ripchord helps you easily compose progressions by playing single notes to trigger full chords. You can watch the tutorial on YouTube: Ripchord Overview

Expansion Packs

Anyone is welcome to make expansion packs for Ripchord, and give them away or sell them, without any further permission required. We don't sell any expansion packs directly, or take any kind of cut from third party expansion pack sales.

Open Source

Ripchord is open source under GNU GPLv3. You can check out the source code on Github: Source Code

Plugin Formats

Ripchord is avalailable as an AU or VST3 for Mac, and a VST3 for Windows. We get a lot of requests for a VST2 version of Ripchord. Actually the first version of Ripchord we made was a VST2, and then we found out that Steinberg would not let us give it to anyone. Steinberg stopped granting any new VST2 licenses in 2018 because they are trying to retire the format, so unfortunately that is the end of the story. This also means that whatever DAW you use must support the full VST3 MIDI spec in order to use Ripchord. More details can be found here: VST2 is Discontinued

Play Mode

Ripchord has two modes, play and edit. Most of the time you will be in play mode, in which you can either play an external MIDI keyboard, or click on the input keys with a mouse, in order to trigger the chords in your preset and compose progressions.


1.

(Button) Favorites or unfavorites the currently loaded preset.

2.

(Button) Opens the menu.

3.

(Button) Allows the chords to be enabled or disabled while maintaining the MIDI routing.

4.

(Button) Contains any MIDI that has been recorded. When it is fully illuminated you can click and drag the MIDI from this button into your DAW.

5.

(Button) Switches between the presets view and the keyboards view.

6.

(Display) The name of the currently loaded preset will be displayed here.

7.

(Arrows) Select the next or previous presets in your collection. You can also use the left, right, up, and down keys on your computer's keyboard to trigger these buttons.

8.

(Button) Switches between play and edit mode.

9.

(Button) Clicking once enables MIDI recording. When enabled, recording will begin the moment the first input note is recieved. Clicking this button a second time will disable MIDI recording.

10.

(Button) Switches the direction of the velocity strum between always LTR, always RTL, LTR then alternate, or RTL then alternate. It can only be clicked if the velocity strum knob has been engaged.

11.

(Knob) Increases the velocity strum, which is the difference in velocity between the first and last notes of a chord. The difference will be spread evenly across all of the notes.

12.

(Knob) Increases the velocity humanization, which is random variation in velocity between all of the notes in the chord.

13.

(Button) Moves the transpose keys to the left on the input keyboard. It can only be clicked if the transpose button has been engaged.

14.

(Button) Engages the transpose keys. When engaged, the bottom two octaves of the input keyboard will operate in latch mode to transpose the chords in the preset up or down one full octave.

15.

(Button) Moves the transpose keys to the right on the input keyboard. It can only be clicked if the transpose button has been engaged.

16.

(Knob) Increases the note humanization, which is random variation in timing between all of the notes in the chord.

17.

(Knob) Increases the note strum, which is the difference in timing between the first and last notes of a chord. The difference will be spread evenly across all of the notes.

18.

(Button) Switches the direction of the note strum between always LTR, always RTL, LTR then alternate, or RTL then alternate. It can only be clicked if the note strum knob has been engaged.

Edit Mode

Edit mode can be used to create a new preset from scratch, or to edit an existing preset. In edit mode, when you mouse click on the input keys, instead of triggering the chord, it will select the input key so that you can assign or modify the output keys that are mapped to it. You can still trigger the chords in edit mode if you have an external MIDI keyboard hooked up, that way you can preview the chords as you edit them.








The MIDI Association MIDI 2.0 Specifications (Complete) PDF [FREE]



MIDI 2.0 is an extension of MIDI 1.0. It does not replace MIDI 1.0 but builds on the core principles, architecture, and semantics of MIDI 1.0.

A foundational architecture for MIDI 2.0 expansion is defined by the MIDI Capability Inquiry (MIDI-CI) specification. MIDI-CI allows Devices with bidirectional communication to agree to use extended MIDI capabilities beyond those already defined in MIDI 1.0, while carefully protecting backward compatibility.

MIDI 2.0 is not a stand-alone specification. Manufacturers and developers must have a thorough understanding of MIDI 1.0 in order to implement MIDI 2.0.

MIDI 2.0 Core Specifications:

These documents make up the MIDI 2.0 Core Specifications. Please click on individual name to access details for document:

  • MIDI 2.0 Specification Overview

  • MIDI Capability Inquiry (MIDI-CI)

  • Common Rules for MIDI-CI Profiles

  • Common Rules for MIDI-CI Property Exchange

  • Universal MIDI Packet (UMP) Format an MIDI 2.0 Protocol

  • MIDI Clip File Specification (SMF format for UMP)

Protocol

The MIDI 2.0 Protocol is an extension of the MIDI 1.0 Protocol. Architectural concepts and semantics remain the same as MIDI 1.0. Compatibility for translation to/from the MIDI 1.0 Protocol is given high priority in the design of the MIDI 2.0 Protocol.

Compared to the MIDI 1.0 Protocol, MIDI 2.0 Protocol messages have extended data resolution for all Channel Voice Messages. New properties have been added to some Channel Voice Messages, and new Channel Voice Messages have been added with greatly improved Per-Note control and much more musical expression.

Property Exchange

Property Exchange is part of the MIDI Capability Inquiry (MIDI-CI) specification and MIDI 2.0. Property Exchange is a method for getting and setting various data, called Resources, between two Devices. Resources are exchanged inside two payload fields of System Exclusive Messages defined by MIDI-CI, the Header Data field and Property Data field. This document defines only the contents of the Header Data and Property Data fields. For information on how to transmit and receive these Resource payloads inside MIDI-CI System Exclusive messages, see the MIDI Capability Inquiry specification and Common Rules for MIDI-CI Property Exchange specification.

Profiles

A Profile is a defined set of rules for how a MIDI receiver device implementing the Profile shall respond to a chosen set of MIDI messages to achieve a particular purpose or to suit a particular application.
