Page 4: 1: Introduction
1: Introduction The MIDI Patch Changer is the perfect solution when you need to control MIDI presets for one or more devices, but a giant keyboard controller or a MIDI footswitch/pedalboard just won’t do. The MIDI Patch Changer has all the features you'd expect in a full-featured patch-changing controller. -
Page 5: Understanding The Keypad
Understanding the Keypad The Mode Keys: The MIDI Patch Changer has three major function groups (modes). o Manual Mode is for sending patch changes by hand “on-the-fly”. o Preset Mode is for sending pre- arranged patch changes and MIDI data during live performance. -
Page 6: Hooking Up
The Bank MSB and Bank LSB are used to select/enable/disable the sending of Banks Select messages in Manual Mode. In this mode they act like a mute button. Hooking Up There are several ways to connect the MIDI Patch Changer to your gear and/or 5-Pin DIN MIDI Gear RJ Cable MIDI IN... - Page 7 USB to PC (Sequencer, Soft Synth, etc.) USB Cable If you are hooking the MIDI Patch Changer keypad to a PC that has USB, then you can use the supplied RJ- to-USB cable: o Connect the RJ end into the back of the keypad o Then connect the USB connector into your PC or USB hub The PC (Mac or Windows) will use the basic class drivers supplied with the OS.

Page 10: To Send The Bank And Patch Values
To Send the Bank and Patch Values While in Manual Mode, pressing Enter at any time causes all of the displayed (enabled) data to be transmitted. Scrolling through Patches With the cursor flashing on the Patch value, pressing an Up or Down arrow key causes the displayed patch value to be incremented or decremented by one, and the new displayed (enabled) data to be transmitted. -
Page 11: 3: Preset Mode
3: Preset Mode Preset mode allows you to pre-configure the keypad for performance situations where you need to change patches on a lot of gear with minimum fuss. In this mode you can set up to 16 patch/bank changes per Preset (one per MIDI channel). -
Page 12: Changing Presets By Number

Page 23: Preset Mode Browsing
Preset Mode Browsing With Preset Mode set to NORMAL, using the arrows keys (or ENTER or typing a preset number in) causes an instant Preset data transmit. With Preset Mode set to BROWSE, the arrow keys do NOT cause a data transmit. -
Page 24: Send A Preset (Via System Exclusive)
Send a Preset (via System Exclusive) You can send one Preset manually to a host PC using this menu. Type in the number of the Preset you wish to transmit (1 to 200) and press ENTER. The keypad will send the Sys Ex data (as described in the appendix). Make sure your PC is set to NOT echo the data back out again to the Keypad! In order to send a Preset to the keypad, simply send it at any time from your PC. -
Page 25: System Exclusive Mfg Id
The System Exclusive Manufacturing ID is used to uniquely identify a specific MIDI device while doing Sys Ex dumps from a host PC. You can adjust the Sys Ex ID of the MIDI Patch Changer keypad so that it does not conflict with any of your other MIDI gear. -

Page 28: 9: Using The Windows Editor
9: Using the Windows Editor Please Note: If you wish to craft an editor for another platform, please refer to the system exclusive implementation in the appendix. You can edit the individual Presets on the device or by sending new values from a PC using the free editor/librarian (or manually using hand-crafted System Exclusive data). -
Page 29: Editor Features
Editor Features There are a couple of main areas to note: The top toolbar consists of buttons used for file open/save/download and similar operations. The large main tabbed panel has four tabs: Presets, Chains, Speed Dials and Settings. These four panels are where most of the editing takes place. ... -
Page 30: Preset Panel
One important point to consider is this: you should finalize your Preset positions before making your Chains (or less importantly Speed Dials). Otherwise, moving your Presets around after your Chains have been built might leave your Chains with the wrong Presets in the Links. Preset Panel For each Preset, 1 to 200, you can setup the MSB/LSB Bank Select and Program Change data for any or all of the 16 MIDI channels. -
Page 31: Preset Panel: Edit Midi Data
Preset Panel: Edit MIDI Data Click on either Edit button in the Pre-Patch or Post-Patch Arbitrary MIDI Data boxes. This will open up the MIDI Data editor. - 31 - MPC Keypad v4.00... - Page 32 The keypad allows you to send up to 90 bytes of any MIDI data before and/or after the MIDI Patch Change and Bank Selects. This might consist of controller changes or Sys Ex commands. The top box, marked Type: Predefined, allows you to insert data using one of the shown predefined types.
-
Page 33: Chains Panel
Chains Panel A Chain is a series of Presets that you progress through in order, for instance as you play a song live. The MIDI Patch Changer keypad holds 99 Chains, each of which can hold 18 Presets. Chains are selected using the Chain Selection list on the left. The Links in a given Chain are shown beside it to the right. - Page 34 You add Links (Presets) to the Chain by double-clicking on the Preset list to the far right. Normally you would append Presets to the end of the Chain, but you can move the insertion point with the mouse. To erase a Link, double-click on it. To erase the whole Chain, right-click on the Chain Links and then select “Delete All Links”.
-
Page 35: Speed Dials Panel
Speed Dials Panel You can have up to 9 favourite Presets than can be selected from Preset mode at any time using a hot-key combination. To access them on the keypad, start in Preset mode, then press and hold CLEAR. While holding CLEAR down, press one of the 0 to 9 number keys. -
Page 36: Settings Panel
To delete a Speed Dial, double-click it. Note that unlike Chains, Speed Dials do not push later Presets down when adding them in the middle. This is intentional. Settings Panel The Settings Panel allows you to view some of the Keypad Properties. These are global values set by using the UTIL Menu on the keypad itself. -
Page 37: Toolbar File Operations
Toolbar File Operations All of the files used by the editor/librarian are System Exclusive files and all use the “.syx” extension. For the purposes of this program we distinguish between the three file types used by the software as follows: 1. -
Page 38: Midi
MIDI There are several ways to manage and send the data to the keypad. These methods differ more in the way the file is managed rather than how the cabling is hooked up. 1. File Only. In this case you don’t update the keypad. You only work with files. - Page 39 Notes for MIDIOX At this time we take a moment and a few pages to discuss how one might use and external MIDI application such as MIDIOX … if that’s your thing. If you are using MIDIOX, you should set up MIDIOX’s SysEx configuration. The following recommended settings can be entered by clicking: then...
