Tips & Tricks - Showing Last Recalled Preset on a BLU-10

Indicating the Last Recalled Preset on a BLU-10

Within London ArchitectTM, a Parameter Preset can be created and its values later recalled as part of a user-defined collection called Parameter Preset Groups. These preset messages are Events, not State Variables, so there is no mechanism to track which “Preset” state the system is currently in. However, there are several ways to create an indicator that will show the last preset chosen. Within London Architect this is easy. By dragging a Parameter Preset Group off of the Design Tree onto a Custom Control Panel, a Drop Down Box is created that will show the last state chosen on this control. Unfortunately, this control does not work the same when used on a BLU-10.

The following method creates a control that can be added to a BLU-10 and will display the last preset chosen. Because this method uses a State Variable, this selection will track across multiple BLU-10 and London Architect GUI’s.

Within the Audio Configuration Window, create a Noise Generator for each on the presets needed on the control. In this example I will use four. Name each of the Noise Generators the same as your Presets. Here I’ve chosen Half House, Full House, House w/ Overflow and System Off.

Next, add a Source Selector. In the Properties Window, change the number of inputs to match the number of Noise Generators you are using. Make sure ‘Allow None’ is set to ‘No’, and change ‘Use signal names’ to ‘yes’. This will display the names of the Noise Generators in the Drop Down list. Wire the Noise Generators to the Source Selector. You can wire the output of the Source Selector to a meter to prevent the Compiler from generating a warning, but this is not necessary.

Switch to the Logic Configuration Window and add a Logic Value object. In the Properties window, change the type from Binary to Shift Down. Set the number of outputs to match the number of inputs on the source selector and add one. In this example it has 5 outputs (4+1).

Open the Default Control Panel for the Source Selector and drag the Drop Down Box from inside over to the Logic Value object. This will create a Logic Link between these two objects.

In the Logic Configuration Window, add logic ‘OR’ object and wire the first two outputs of the Logic Value object to the inputs of the Logic ‘OR’. Next Add the correct number of Preset Trigger logic objects, in this example there are four. Wire the objects together as shown in this diagram.

Select the first Preset Trigger, and in Properties, choose ‘Activate Preset on 1’. Click the drop down arrow, select ‘Parameter Preset’, and select the corresponding Parameter Preset off the list. Repeat this for each of the Parameter Presets.

The Source Selector Dropdown Box can be copied to any number of BLU-10 control screens or London Architect Control Panels and will all display the same information and track each other as changes are made.
