DocumentDocumentGPIM-16 16 GPI inputs to MIDI Operating manual FCC STATEMENT FOR GPIM-16: NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Reorient or relocate the receiving antenna. · Increase the separation between the equipment and receiver. · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. · Consult the dealer or an experienced radio/TV technician for help.

The GPIM-16 is very easy to use, but please take a few moments to read through the manual to avoid any operational difficulties. Connections DC IN 9V Plug the power adapter into here. The unit will take an adapter with an output of 9V either regulated or unregulated. The socket is a 2.1mm type with centre positive and is compatible with locking type plugs. Do not use a power supply with an output voltage higher than 9V, and the GPIM-16 must not share an adaptor with any other device. Failure to observe this will invalidate your warranty, and will probably damage the other device, the GPIM-16 and/or the power supply. MIDI In This is provided in order that you can `daisy chain' several boxes together. Any data received at the MIDI In socket is merged with any new data generated from the GPI inputs and everything is then sent to the MIDI outs 1 & 2. There is no limit to the number of GPIM-16 units that can be daisy chained together as the data is re-generated rather than being merely copied. MIDI out 1 & MIDI out 2 MIDI out 1 and MIDI out 2 carry identical MIDI information. The second output is provided so that data can be set to a backup computer system at the same time as supplying the primary computer. Display The display has several functions; In normal operating mode, the display will show three horizontal bars until a GPI input is received, it will then show a number between 1 and 16 to indicate the GPI input which was activated. Note that if two inputs are received in quick succession, it will show the later one. After a couple of seconds, the display will revert to the three dashes display. In this mode, the dots above the display will indicate MIDI In and MIDI out activity. The display is also used for editing, see Edit Mode section later in this manual. Using the GPIM-16 GP Inputs are on pins numbered 1 to 8 of the 9 pin D socket connectors pin 9 is the common ground connection. When power is applied to the GPIM-16, the words KENTON GPIM will scroll across the display, then three horizontal bars will show, indicating that no GPI input has recently been received. Various parameters can be edited and stored see Edit Mode section later in this manual. The GPIM-16 also contains a MIDI analyser see the MIDI analyser section for more information. 3 Edit Mode To put the GPIM-16 into edit mode, use a screwdriver or pen to press the recessed edit button. The edit dot will light to show that it is in edit mode. The para dot will also light to show that the required parameter can be changed by using the INC & DEC buttons. When the required parameter has been selected, press the mode button. The para dot will go out and the val dot will light to indicate that the value can now be changed by using the inc and dec buttons. When the required value has been set, either press the mode button again to select another parameter, or press the edit button again. This will return you to normal operating mode again. Whenever you return to Parameter mode the settings you have changed will be saved. Settings are stored in non-volatile EEPROM memory. Note also that the GPIM-16 will continue to function normally during the edit process, except that the display will not indicate an activated input. The parameter names below also scroll across the display. 4 Parameters chn GP In MIDI transmit channel (default: 1) Range: 1 to 16 Sets the MIDI transmit channel for all GP Inputs. nn1 GP In 1 note number (default: 36) Range: 0 to 120 Sets the note, controller or program number for GP Input number 1 (2 to 8 follow consecutively). oF1 GP In 1-8 off send (default: Yes) Range: Yes or No Sets whether MIDI note off or controller value=0 messages are sent for GP Inputs 1 to 8. Not applicable when using program changes. nn9 GP In 9 note number (default: 44) Range: 0 to 120 Sets the note, controller or program number for GP Input number 9 (10 to 16 follow consecutively). oF9 GP In 9-16 off send (default: Yes) Range: Yes or No Sets whether MIDI note off or controller value=0 messages are sent for GP Inputs 9 to 16. Not applicable when using program changes. dEb GP In debounce time (default: 20) Range: 1 to 995 in 5ms steps Sets the debounce value in milliseconds for all GP Inputs. out MIDI message type (default: notes) [not] Notes [con] Controllers [prg] Program Changes Sets the MIDI message type for all GP Inputs. vEL GP In On velocity (default: 127) Range: 1 to 127 Sets the On velocity value used for all GP Inputs when MIDI notes are being sent. tHr soft thru (default: On) Range: On or Off Sets whether messages received at the MIDI Input are echoed to the MIDI outs. 5 Input Connections Connections for the GP Inputs are a pair of 9 pin D connectors. Below is the view looking at the back of the unit and is the same view as looking at the solder connections of the corresponding plug. Pins 1 8 are the input pins and pin 9 is the common ground connection. The input pins are internally pulled up by 4K7 ohm pullups to +3.3 volts. Shorting an input to ground (pin 9) activates that input. 6 MIDI Analyser Mode The GPIM-16 has a built-in MIDI analyser function. This feature allows you to see what types of MIDI messages are being transmitted by your master keyboard/sequencer making the GPIM-16 a useful diagnostic tool. To enter analyser mode, power on the GPIM-16 whilst holding the MODE button. [AnL] will be displayed while you hold the button down to indicate MIDI Analyser Mode. Upon release of the button, the display will show [rc] for receive channel & status mode. This means the display will show the MIDI receive channel of any messages it receives in the right hand two digits, and will show status in the left digit this is explained further down the page. Using the INC, DEC, and MODE buttons, different types of MIDI messages received may be displayed: MODE DEC INC Short press Long press Short press Long press Short press Long press [rc] Receive channel & status [Pc] Program change [nt] Note number [nv] Velocity [cn] Controller number [cv] Controller value For whichever of the above selected, the GPIM-16 will display the value it receives for the type of message currently selected. Although pitchbend and after-touch are not strictly controllers, when Controller number [cn] mode is selected, [pb] will be displayed if a pitchbend message is received, and [af] will be displayed if an after-touch message is received. If Controller value [cv] mode is selected, and pitchbend or aftertouch messages are received, their values will be displayed. When Receive channel & status [rc] mode is selected, the right hand 2 digits show the received MIDI channel (if applicable) and the left-hand digit operates as a received MIDI message indicator. LED segments will flash when then following types of messages are received: Note on, Note off, SysEx, Timing clock (MIDI clock), Start, Stop, Continue. The top left dot (any MIDI message) operates in all modes Any MIDI message Clock start SysEx Note on Clock continue MIDI clock Note off Clock stop To exit MIDI analyser mode, the power switch of the GPIM-16 must be turned off then on again. 7 Factory Defaults If you wish to reset your GPIM-16 to factory defaults, you can do so by turning the power on whilst holding down all three push buttons (MODE, DEC & INC). This will return the GPIM-16 to its default settings. [Fd] (factory defaults) will momentarily be displayed when this has been done. Displaying the Firmware Version Power the unit on while holding the INC button pressed. While the INC button is held, the firmware revision number [2xxx] will be displayed in pairs two dashes then digits 1 & 2 then digits 3 & 4 repeated. Releasing the INC button will revert to the normal operational mode.
