STELLARR

Grid and Routing

Test whenever you touch the connection layer, block bypass, block movement, splice logic, or graph topology.

Prerequisites

  • A preset with at least 3 blocks in a chain (Input > Plugin > Output)

Test Cases

TC-GR-001: Connect blocks in a chain

Steps:

  1. Add an Input, a Plugin block, and an Output to the grid
  2. Connect Input to Plugin by dragging from the right edge to the left edge
  3. Connect Plugin to Output

Expected: Audio flows through the chain. Route highlights show the signal path when a block is selected.

TC-GR-002: Mute block breaks route highlight

Steps:

  1. Select a block in the middle of a chain
  2. Set bypass mode to “Mute”
  3. Toggle bypass on

Expected: Route highlight breaks at the muted block immediately (no need to click away).

TC-GR-003: Thru bypass preserves route highlight

Steps:

  1. Select a block in the middle of a chain
  2. Set bypass mode to “Thru”
  3. Toggle bypass on

Expected: Route highlight stays connected through the bypassed block. Audio passes through.

TC-GR-004: Remove block from middle of chain

Steps:

  1. Build a chain: Input > A > B > Output
  2. Remove block A

Expected: Block A is removed. Connections to/from A are cleaned up. Block B is disconnected from Input (no auto-reconnect).

TC-GR-005: Splice block into existing connection

Steps:

  1. Build a chain: Input > Output (direct connection)
  2. Add a new plugin block by dropping it onto the connection line

Expected: New block is spliced in: Input > New > Output. Audio flows through all three.

TC-GR-006: Move block to new position

Steps:

  1. Place a block at column 3, row 2
  2. Drag it to column 6, row 4

Expected: Block moves. Connections follow. Audio continues flowing.

TC-GR-007: Drop target highlight during drag

Steps:

  1. Start dragging a block
  2. Move the cursor over various empty cells

Expected: The cell under the cursor highlights in blue (drop target indicator). Only one cell is highlighted at a time. Occupied cells do not highlight. No ghost highlights remain after dropping.

TC-GR-008: Drag and drop back to original position

Steps:

  1. Start dragging a block
  2. Release it on its original cell

Expected: Block stays in place. No ghost highlights on any cell after release.

TC-GR-009: Click to select still works after drag

Steps:

  1. Click a block without dragging (no mouse movement)

Expected: Block is selected (not dragged). Options panel shows the block’s settings.

TC-GR-010: Splice fails when path is broken by muted block

Steps:

  1. Build a chain: Input > A > B > Output
  2. Mute block A (bypass mode “Mute”)
  3. Click an empty cell on the connection line between A and B
  4. Add a Plugin block

Expected: New block should splice into the connection between A and B regardless of bypass state.

TC-GR-011: Mute FX In — reverb tails ring out with dry pass-through

Steps:

  1. Build a chain: Input > Reverb plugin > Output
  2. Set reverb to a long decay (2+ seconds)
  3. Set bypass mode to “Mute FX In”
  4. Play guitar, then toggle bypass on

Expected: Dry guitar signal continues immediately. Reverb tail fades out naturally over the decay time. Level and Balance controls still affect the output while bypassed.

TC-GR-012: Mute FX Out — signal enters effect before engaging

Steps:

  1. Build a chain: Input > Reverb plugin > Output
  2. Set bypass mode to “Mute FX Out”
  3. Toggle bypass on
  4. Play guitar for a few seconds (signal enters reverb silently)
  5. Toggle bypass off

Expected: While bypassed, dry guitar signal passes through. When un-bypassed, reverb immediately has a tail built up from the signal that was entering while bypassed.

TC-GR-013: Mute In — tails ring, no dry

Steps:

  1. Build a chain: Input > Delay plugin > Output
  2. Set bypass mode to “Mute In”
  3. Play guitar, then toggle bypass on

Expected: Delay repeats continue (tails ring out). Dry signal is silenced — only the effect tail is heard, fading to silence.

TC-GR-014: Mute Out — signal enters, output silenced

Steps:

  1. Build a chain: Input > Delay plugin > Output
  2. Set bypass mode to “Mute Out”
  3. Toggle bypass on, play guitar
  4. Toggle bypass off

Expected: While bypassed, total silence. When un-bypassed, delay has accumulated repeats from the input signal.

TC-GR-015: FX bypass modes with scene recall

Steps:

  1. Build a chain: Input > Reverb > Output
  2. Set reverb bypass mode to “Mute FX In”
  3. Create scene 0 with reverb active, scene 1 with reverb bypassed
  4. Play guitar, recall scene 1

Expected: Reverb tail rings out naturally. Dry signal continues without interruption. Recalling scene 0 re-engages the reverb.

Status: Known bug (pre-existing). Splice detection does not account for muted blocks in the path.

TC-GR-011: Multiple parallel chains

Steps:

  1. Add two Input blocks and two Output blocks
  2. Create two independent chains: Input1 > Plugin1 > Output1, Input2 > Plugin2 > Output2

Expected: Both chains process audio independently. Selecting a block in one chain highlights only that chain’s route.
