Voice Stack Tog

A 16-slot per-stack gate that enables or silences each voice-stack position independently.

What it does #

Voice Stack Tog stores one on/off choice for each stack position. As every stacked voice executes the shared Grid patch, its stack index selects the corresponding switch and either passes or suppresses that voice.

Controls and ports #

The row of stack switches defines which positions are enabled. In receives the current stacked voice, the hidden stack index chooses its switch, and Out either passes that voice or returns zero.

Practical uses #

• Remove selected voices from a stack while keeping the stack's pitch, phase, or modulation layout intact.
• Create sparse or asymmetric unison structures by activating only chosen stack positions.
• Use several Voice Stack Tog modules in different branches so each stack voice follows a different processing topology.

Things to know #

• The recovered implementation supports 16 switch entries.
• The current stack index selects exactly one entry; the module does not sum or rotate among voices.
• Disabled positions output exact zero in the recovered body.
• No fade or smoothing is visible in Nitro, so switching sustained audio may click unless the wrapper adds behavior not recovered here.
• This module is specific to voice stacks and does not replace ordinary polyphonic voice management.

Technical details #

A high-confidence Nitro implementation candidate supports the technical summary, but the visible-module mapping remains inferred.

The exact grid/mix/voice_stack_toggle body indexes a 16-element Boolean Enable array with stack_index. If the selected entry is true, out=in and the selected LED value is 1; otherwise out=0 and its LED is 0. No interpolation, crossfade, or state smoother appears in the body.

Open questions #

• Measure live switch changes on sustained audio to confirm whether any wrapper-level de-clicking occurs.
• Test inactive stack slots, stack-count changes, voice reallocation, initialization, and preset recall.
• Verify stack-index ordering and the exact LED behavior when voices are inactive.

Version and sources #

Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
