The MIDI MateTM provides many different features and modes of operation. Its modes of operation range from very simple (transmitting a single program change on a single MIDI channel) to complex (such as transmitting six program changes on six separate MIDI channels, five control changes on five separate MIDI channels and a continuous control change on a separate MIDI channel). The MIDI MateTM is capable of sending three different kinds of MIDI commands on a specified MIDI channel to any MIDI device. To use the MIDI MateTM to its full potential requires some understanding of MIDI commands and specifications. MIDI MIDI stands for Musical Instrument Digital Interface, and is an industry standard system for communication between musical equipment. Some MIDI devices only transmit MIDI messages, these are called transmitters. There are other MIDI devices which can only receive MIDI messages, these are called receivers. In addition, there are also MIDI devices that both receive and transmit MIDI messages which can be called receivers or transmitters. A receiver may be thought of as a MIDI "ear", that is to say that it listens but never speaks. A MIDI transmitter may be thought of as a MIDI "mouth", that is to say it speaks, but never listens. A device that can both transmit and receive MIDI may be thought of as having a MIDI "ear" and a MIDI "mouth" that allows it to both listen and speak. A very simple MIDI setup requires only that there be a MIDI transmitter and a MIDI receiver - one to speak and one to listen. More complex MIDI setups may have devices that speak and listen to each other at the same time. The MIDI MateTM is a MIDI transmitter, capable of changing parameters on MIDI receivers. MIDI Channel A MIDI channel is simply a way of encoding a command so that multiple devices may talk to each other using the same physical wires. Unless messages are encoded for the same channel, the transmitted message will be ignored by the receiving device. By encoding signals in this manner, the MIDI MateTM can tell a particular receiving device to perform a certain task while simultaneously telling a different receiving 1 MIDI MateTM Manual device to do something else. Each receiving device only acts on the command intended for it. MIDI Commands The most common type of MIDI command is the MIDI program change (often called a patch change). This command is intended to recall the programmed settings of a receiving device. A programmable device, such as the Rocktron ProGAPTM guitar preamp, may have parameters such as the gain set to 40, the bass level set to 5dB, and the output level set to 10dB. These settings can then be stored in preset #10. Each time the ProGAPTM receives program change 10, these settings are recalled. Another type of MIDI command is the MIDI control change. This command is used to set a single parameter on a receiving unit to a specific value. The preset of the receiving device is not changed, only the value of the specified parameter. The specified parameter on the receiving device is mapped to a number called a control number. A transmitting device sending a control change will specify the MIDI channel, the control number, and the value that the specified parameter should change to, or the controller value. The controller value is a number from 0 to 127 that the receiving device attaches to an actual parameter value. How a device responds to a MIDI control change depends on both the device and the parameter. Some devices will not understand a MIDI control change and will simply ignore it. Other devices, like the Rocktron ProGAPTM, will respond to MIDI control changes. All of the parameters that determine the sound of the ProGAPTM can be adjusted through MIDI control changes. The ProGAPTM has 64 values for each parameter with each parameter value corresponding to a different controller value. A convenient way to perform MIDI control changes on these parameters is to use a continuous controller. An expression pedal, volume pedal, fader, or any potentiometer that can be plugged into the MIDI MateTM qualifies as a continuous controller. As the continuous controller resistance is changed, a new controller value is sent to the receiving device. For example, if an expression pedal is plugged into the MIDI MateTM, the pedal control number is set to 10, and the ProGAPTM's output level is mapped to control number 10, moving the pedal back and forth causes the output level to change. To achieve this, all that must be done is to match control numbers between the parameter of the receiving device and the pedal of the transmitting device. It is important to remember that the MIDI channels of the transmitting and receiving devices must also match. 2 The loop and controls on the Rocktron ProGAPTM can be changed through MIDI control changes as well. Since the loop and controls can have only an on or off status, they are conveniently called on/off controllers. For on/off controllers, a control change command with a controller value of less than 64 is interpreted to be off. A value greater than 63 is interpreted to be on. 3 MIDI MateTM Manual Quick Setup To start using the MIDI MateTM right away, use a 5 pin MIDI connector and plug one end into the MIDI OUT jack of the MIDI MateTM. Plug the other end into the MIDI IN jack of a MIDI receiving device. Plug the adaptor supplied with the MIDI MateTM into the POWER jack of the MIDI MateTM. Plug the adaptor into a nearby compatible wall socket. Now assign SET1's MIDI channel to the same MIDI channel of the device that is receiving MIDI. Press the 2ND button so that the 2ND LED lights. Now press the EDIT FUNCTION SELECT "à" button twice, until "MIDI Channels" scrolls across the display. Allow the scrolling to finish, and "S1CH 1" will be displayed. This shows that SET1 is assigned to MIDI channel 1. To change the MIDI channel to match a receiving device's MIDI channel, use the BANK (ADJUST) buttons. When finished, press the 2ND button to turn off the 2ND LED. Now the MIDI MateTM will send the program change displayed by the three character display to any MIDI receiver on the same channel.
