Slider2

Slider2 is the slider you’ll use in practice: a draggable control that puts out a voltage, and remembers its position in the patch. It’s under Controls in the Module Browser.

Unlike most entries in the browser, Slider2 is a prefab rather than a single module — a small ready-made container holding a slider sub-control wired to a patch-memory module. That detail explains most of its behaviour, and one export gotcha.

Plugs

Pin	Type	Description
Visible	Bool	Shows or hides the control on the panel
Slider	Control	The slider’s value — wire this to whatever you want to control
Spare	—	The container’s spare input, for adding your own connections inside

Usage

Connect Slider to the input you want to drive: an oscillator’s Pitch, a filter’s cutoff, a VCA’s Volume. Your First Synth uses one to sweep a filter.

The patch-memory module inside is what makes the slider more than a knob on screen:

• Its position is saved with the patch and restored with presets
• It is registered as a parameter, so a host DAW can automate it — with no Patch Automator needed
• The parameter takes its name from the pin it drives. Wire a Slider2 to a StateVar Filter’s Pitch and the host sees a parameter called StateVar Filter Pitch.

Parameters

Select the module and the properties panel shows the parameter behind it:

Property	Description
Value	The slider’s current position, in volts
Low	Value at the bottom of travel (default 0.0)
High	Value at the top of travel (default 10.0)
Hint	Tooltip text
MIDI	MIDI controller assignment for the parameter
Ignore Program Change	Leave this control alone when the patch changes
Private	Hide the parameter from the host
Stateful	Save the value with the patch (on by default)

Low and High are the ones you’ll reach for most: a slider driving a filter cutoff wants the full 0–10 V, while one trimming a level may want a much narrower range.

The container’s own pins — Controls on Module, Visible and Ignore Program Change — appear above the parameters, along with the usual container properties.

A stray Slider2 is a stray container

Because a prefab is a container, a Slider2 dropped on the master canvas instead of inside your synth counts as a second exportable container — one of the standard ways to get “Many Containers in main window” at export time. Keep your controls inside the container you intend to export. See Creating VST Plugins.

Two things called Slider2

A module search for slider can also turn up a Slider2 in the Debug category. That one is deprecated and isn’t present in release builds — pick the Controls entry.

For the older, plain slider module see Slider.
