The Digital Signal Processor:
Crate’s Digital Signal Processing offers 16 exciting digital effects, accessible through the DSP
Mode control. The effects are described below.

Channel Tracking:
Your Crate GFX-120T/212T gives you the power of Channel Tracking! Once you select a DSP
setting for each channel, Channel Tracking recalls those DSP settings automatically – without
changing the DSP controls! For example:
• Select the Clean channel. Set the DSP Mode to “FLNG 1”
(slow deep reverb)
• Select the Overdrive channel, Gain 1. Set the DSP Mode to “CHO 1”
(slow tremolo reverb)
(the setting for the Clean channel is now saved to memory)
• Select the Overdrive channel, Gain 2. Set the DSP Mode to “T-WAH000”
(touch sensitive wah-wah)
(the setting for the Overdrive channel, Gain 1 is now saved to memory)
• Reselect the Clean channel
(the setting for the Overdrive channel, Gain 2 is now saved to memory)
Now when you go back to the Clean channel, even though the DSP Mode was last set to “T-WAH,”
Channel Tracking automatically recalls the last setting for the Clean channel – in this example,
“FLNG 1.” Change to the Overdrive channel, Gain 1, and “CHO 1” is recalled. Change to the
Overdrive channel, Gain 2, and “T-WAH” is recalled. That’s the power of Channel Tracking!
(Note: Even when the power is turned off, Channel Tracking still retains the settings – until you change them!)
