P age 2 P age 3 R/C Manual 1. R/C OVERVIEW 1. Overview of R/C (Remote Control) 1.1 R/C INTERF ACE CONNECTORS Only ONE source of control is accepted. Front panel selection of MIDI or LAN must be made on each 1788A. The 1788A always wakes up in the last mode used. 1.2 R/C INTERF ACES Control Language: MIDI SysEx Whether using the 1788A ’s Ethernet [...]

P age 4 P age 5 R/C Manual 1. R/C OVERVIEW Indirect MIDI Control MIDI controllers can access 1788A ’s through the LAN indirectly by interfacing with one or more 1788A-R’s. A most basic example is illustrated below . Ethernet LAN Many applications call for more sophisticated remote control or control at greater distances than a MIDI port can han[...]

P age 4 P age 5 R/C Manual 1. R/C OVERVIEW A CONSTELLATION refers to the whole array of preamps attached to the same LAN. It may comprise only one 1788A or up to 128 of them. Preamps may be assigned NET numbers placing them in different banks even when any given bank is not filled. For example, you could have up to 16 preamps all within one bank, o[...]

P age 6 P age 7 R/C Manual 1. R/C OVERVIEW Preset Management Software-managed presets are more extensive than using hardware controllers. Individual channel labels, group labels, and preset naming of up to 128 characters each in file save mode and 16 characters each in hardware save mode is supported. Preset Recall and Preset Store is easier to acc[...]

P age 6 P age 7 R/C Manual 1. R/C OVERVIEW Management Extents Storing and recalling presets can be done only by remote control. Recalling presets can be done by indirect MIDI as well as by the 1788A-R and the PC software R/C. The extent of preset management depends on the form of R/C according to the table below . Constellation and Bank Capture/Rec[...]

P age 8 P age 9 R/C Manual 2. USING MIDI The software remote can handle communications with all 1788A ’s in the constellation directly . Even when one or more 1788A-R’s are detected, the software directly transmits control to all 1788A ’s. It also communicates with all 1788A-R’s to keep them synchronized. This harmony improves remote contro[...]

P age 8 P age 9 R/C Manual 2. USING MIDI 2. Using MIDI 2.1 DIRECT MIDI CONTROL MIDI control can be piped directly to a 1788A ’s MIDI Input port from any suitable controller . Suitable controllers are devices such as mixing or lighting consoles or stand- alone MIDI controllers that have programmable physical controls such as pushbuttons and slider[...]

P age 10 P age 11 R/C Manual 2. USING MIDI 2.1.4 Understanding Ch, Dev and Net Offsets Please observe two important facts about MIDI Channel, Device, and Net Numbers. 1. All three are displayed in decimal form on the 1788A and 1788A-R front panels. Ch and Dev go from 01 to 16 and Net goes from 001 to 128. Y ou will need to convert decimal to hexade[...]

P age 10 P age 11 R/C Manual 2. USING MIDI NOTE: We will refer to the Reference Data at the end of this chapter for command codes used by the 1788A. When programming each control, use the following setup: 1. Single-byte transmit 2. F aders: string; Buttons: string toggle 3. F ader Limits: 26 to 65 4. Faders: use “pr” in the value byte. This is [...]

USING MIDI additional 1788A is used, the second set of eight faders and buttons of the PC1600 could be coded exactly like the previous tables, except with the channel and/or device number changed to match the second 1788A . Remember , in this case, NET number is just a placeholder and can be anything. 2.1.8 Broad Com[...]

P age 12 P age 13 R/C Manual 2. USING MIDI 2.2 INDIRECT MIDI CONTROL If you want to employ a MIDI form of control when the 1788A ’s are connected to R/C units by LAN, direct connection to the 1788A ’s MIDI ports cannot be used. This is because only one R/C medium can be accepted by the 1788A at a time: LAN or MIDI. When LAN is selected, the 178[...]

P age 14 P age 15 R/C Manual 2. USING MIDI 2.2.1 Hardware Hook-up Anything from a single 1788A to a large constellation can be controlled by indirect MIDI through 1788A-R’s. Figure 2-5 suggests how this is done. The controller’s MIDI OUT is connected to the first 1788A-R’s MIDI IN. The next 1788A-R’s MIDI IN is connected to the preceding MI[...]

P age 14 P age 15 R/C Manual 2. USING MIDI 2.2.3 Expanding the SysEx String Just like direct MIDI control, you can repeat 3-byte commands within the parametric SysEx string to send multiple commands to a single 1788A as shown by figure 2-7. NOTE: Y ou cannot expand the 2-byte MIDI Preset string. 2.2.4 1788A-R’s Odd MIDI I.D. All 1788A-R units are[...]

However , the 1788A-R does not have facilities for merging. Y ou’ll probably need a commercially available MIDI merging box to receive the MIDI Outs from the multiple cont[...]
