Contrast Range: 1 - 8 System Functions (SYS) Thru Port Range: 1 - 8 This determines the contrast of the display. Adjust this as necessary for optimum visibility. (At extreme settings, the display may not be readable.) Dump Interval (DumpIntrval) Settings: 50, 100, 150, 200, 300 This determines the length of time the MU100R pauses when sending blocks of data in the Dump Out functions. If the receiving device fails to process the data or displays a "buffer full" type message, try setting this parameter to a higher value and send the data again. Some MIDI devices and sequencers are capable of transmitting data over several MIDI "ports," effectively breaking the 16channel barrier. When this data is received via the TO HOST terminal on the MU100R, this parameter determines which MIDI port's data will be routed through the MIDI OUT terminal. This allows you to connect another multitimbral tone generator to the MU100R and play back data over 48 independent MIDI channels - 32 on the MU100R and another 16 on the connected tone generator. NOTE The MU100R can receive Cable messages (F5) when the TO HOST terminal is connected to the serial terminal of a computer. On the MU100R, MIDI receive channels A1 - A16 are controlled from Port 1, and channels B1 - B16 are controlled from Port 2. If the software you are using can address separate MIDI ports, data can be received over 32 channels simultaneously, allowing 32 parts to be played with only one serial cable. By connecting another multitimbral tone generator to the MIDI OUT terminal of the MU100R and setting the Thru Port function to a value other than 1 or 2, you can play back data over a total of 48 MIDI channels - 32 on the MU100R and another 16 on the connected tone generator.
