Source components are shown only in advanced view. Click the Advanced button to switch to advanced view, then click the A/B/C/D button to select the source you want to edit.
The source filter module provides three multimode filters, which can be configured either in series or in parallel. The source filters let you filter each source independently. The main filters, by comparison, process a mix of all four sources. See Alchemy main filter controls.
Tip: Though you can use filters at multiple locations in the signal path, you can attain identical or similar results by careful use of fewer filters, which helps to reduce CPU load.
When the source filters are configured in series, the signal passes through the three filters, one after the other.
When the source filters are configured in parallel, the signal is split and fed through the three filters simultaneously.
The most common filter controls are listed. Note that the chosen filter type can change both the name and function of available controls, notably the Cutoff, Resonance, and Drive parameters. See Alchemy filter types and Alchemy source filter use tips.
1/2/3 buttons: Select each filter. The three filters are independent and can have unique settings. The LED at the top of each button shows on (lit) or off (unlit) status.
On/Off buttons: Enable or disable each filter (1, 2, or 3).
Filter type pop-up menu and field: Choose the filter type. Use the descriptive names Clean, Edgy, Gritty, Rich, Sharp, and Smooth to make a choice that is right for your sound. You can step through the available filter types with the Previous and Next buttons (the arrows).
Ser/Par buttons: Set the filter routing configuration. Series runs from filter 1 into filter 2. Parallel runs the two filters side-by-side.
Cutoff knob and field: Set the cutoff frequency for the chosen filter type.
Resonance knob and field: Boost or cut frequencies above, below, or surrounding the value set with the Cutoff knob. Resonance behavior varies among filter types.
Drive knob and field: Overdrive the filter. This can lead to intense distortions and aliasing, depending on filter type.
Send knob: Set the level of the source output (post source filters, if used) sent to the destinations specified with the Send Destination pop-up menu.
Send Destination pop-up menu: Determine where the source output is sent (post source filters, if used).
F1/F2: Source output is routed to main filters 1 and 2. The balance between these targets is set with the Send knob.
F1/FX A/B/C/D: Source output is routed to main filter 1 and effects rack A, B, C, or D. The balance between these targets is set with the Send knob.
F2/FX A/B/C/D: Source output is routed to main filter 2 and effects rack A, B, C, or D. The balance between these targets is set with the Send knob.
Note: Signals sent to effects rack A, B, C, or D destinations bypass the main filters when the Send knob is set to the full-right position. See Alchemy effects overview.
