Each Bus has 32 'playable' slots in its Rack, which are the primary 'Notes' of IQSynth.
The slot panel shows details of the currently selected slot/bus/screen and has 3 main sections.
Left : Previews & Transport controls
The smaller preview shows the input (source) (or layers for a Bus slot) the larger preview shows the output with any effects enabled. Below the large preview is a scratching control and then for a normal loaded slot the standard transport controls of pause/rev/fwd/stop.
The example above is a loaded slot in Bus A with an effect mixed in.
Centre : The FX Stack
The FX stack has 8 spaces. Each loaded effect (Plugin) can be enabled/disabled and has a Wet/Dry mix control.
You use the F1-F8 (function keys) to select or trigger the effect.
The FX stack also has trigger behaviours, similar to the rack trigger options, see Rack Controls.
The Workbench and each Bus and Screen are also types of Slots and can have their own FX stack.
One of the most powerful tools in IQSynth is the ability to drag and drop the FXStack bundle using this icon ...
... to clone the setup onto any other slot or create an AuxFX for global use.
Right: Assigned parameter macros
You can drag and drop parameters from any FX panel onto a macro control. Unless you have manually setup by drag and drop, the macro parameters are auto assigned from whichever is the current selected FX and will change as you switch between selecting FX.
When a 'Snapshot' or 'AuxFX' is created, only the manual assignments are stored with the setup.
Mixer Plugins (colour coded blue in the plugins area) have 1 limitation, they only work for Buses and Output slots.
