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 accomplish. Both “save to hardware” and “save to file” are supported.

NOTE: MIDI control is NOT accepted by the PC Software controller, even if the computer is outfitted with MIDI ports. When a LAN is used, MIDI controllers can gain access to a bank of 1788A’s only through a 1788A-Runit’s MIDI port.

Wide System View

Enormous numbers of preamps can be displayed in thumbnail form and quickly switched to the main control area. Thumbnails indicate channel signal levels and flash to indicate if a channel is clipping to readily alert the operator of problem spots needing attention.

Massive Grouping & Control

Channel grouping of controls can be done across the constellation of 1788A’s, not just within a single 1788A as with the hardware R/C. Four constellation groups are supported. This means you can assign any channel of any 1788A preamp to any one of the four groups. When any channel’s control is changed, all others in that group change accordingly. If gain is changed, there are two user options: Proportional or Absolute. If Proportional is selected, grouped gains move proportionally. If Absolute is selected, all gains snap to the same gain as the channel that was adjusted.

1.6 COMBINED R/C

With minimal restraints, the hardware (1788A-R) and computer based remote control can co-exist on the same LAN. Any given control source takes priority at the instant it issues a command. All others that are online will update their references as necessary to reflect the change. Contention for control is taken care of by the proprietary UDP communications system. Jam-ups and lost control are prevented even while multiple controllers are busy making changes. There is no hierarchy of procedure. All controllers are peers.

1.7 ABOUT PRESETS

One of the most useful features available through R/C is the ability to save, edit and recall up to 60 presets.

Because of the flexibility built into the 1788A and its remote controllers, a distributed approach was used for storing preset data in hardware.

60 bank-wide presets can be memorized in each 1788A-R. Each of the 60 presets contains enough data to define the entire state of the each of the 16 positions in the bank. The preset memory also stores the preset’s given label, the preamp’s given label, and all given channel labels, (up to 16 characters long each) all of which must be defined through the PC remote software.

Each 1788A contains its own memory dedicated to storing the current machine state. The last preset propagated is stored in the 1788A’s memory enabling it to wake up in its prior state should the preamp become powered down.

NOTE: 1788A-R hardware remote cannot create or display a preset label (only a number), preamp label, or channel labels.
