RATIO • Determines the change in output level as a function of the change in input level, once the signal level drops below the threshold. This is sometimes called downward expansion. The ratio control ranges from 1:1.0 to 1:inf. Thus, if the ratio is 1:2, a decrease in input level of 10 dB results in a 20 dB decrease in output level (assuming the input is below the threshold level). MIDI • Enables external MIDI triggering for the gate. • This can be useful for gating drums based on a sequenced MIDI drum pattern. • To set up MIDI gate triggering: 1. Select MIDI Map from the Windows menu. 2. Select New MIDI Route from the Edit window. 3. Assign a MIDI note by selecting Note from the MIDI Status drop-down menu. 4. Select Gate MIDI Trigger from the Parameter column. 5. Send a MIDI note to the D8B from a sequencer or other MIDI device. The Mode setting in the MIDI Map determines when the gate opens and closes (see "Creating a Route" on page 94). • Gate MIDI Enable can also be turned on and off via external MIDI note commands. ACTIVE • Click the ACTIVE button to turn on the gate for the selected channel. MENU • Click the MENU button to Open, Save, Reset, Undo, Cut, Copy, and Paste a Gate patch. MEM A/B • Each MEMory stores the most recent MEM A or MEM B EQ settings made for the selected channel. • Click either of these memory positions to instantly recall the stored settings. • Ideal for making quick A/B comparisons between gate settings. Note: Meter View and Meter Mode are not stored in the MEM A or MEM B settings. Additional Fat Channel Controls CHANNEL SELECT • Use the arrows on either side of the channel number (or the arrow keys on the keyboard) to scroll up or down through the D8B channels. • Click in the "Chan. Select" window for a pull-down of all the channels. CHANNEL NAME • This displays the channel name. • Double-click on the name to highlight it, then type in the new channel name (up to 16 characters). Press Enter or click elsewhere to complete the operation. ASSIGNMENT • Assign the channel to the main L/R bus or any of the 8 bus outputs. D8B Manual • Chapter 3 • page 88 ROUTE TO TAPE • Assign the channel to a tape output. • Highlight the desired numbers to send the channel to one or many tape outputs. • This is the most visual way to tell if a channel is routed to several tape outputs. • A channel can be assigned to more than one tape out, but only the last one selected appears in the channel's OUT window (in the overview screen). • No two channels can be assigned to the same tape output. To sum channels to a tape output, assign them to a bus, the route the bus to a tape out. Phase • Highlight PHASE to invert the channel polarity by 180 degrees. Aux Sends • Use the on-screen knobs to adjust any of the aux send levels. • Press Control while clicking the Aux knob to set Aux send level to unity gain. • Click the PRE button directly below the Aux send knob to toggle the individual Aux Pre/Post status. • Click the OFF button directly below the Aux send knob to toggle the individual channel Aux on and off (mute).
