Integration
QLab (Figure 53)
Showcaller turns Figure 53 QLab into a voice-driven show-calling engine. Over low-latency OSC it presses GO, holds and resumes cues, and recovers with a single panic, while also reaching deep into cue properties, timing, audio levels, and design-time video, light, and spatial-audio controls. From a one-operator corporate ballroom to a fully cued theatrical run, Showcaller calls the show so the operator can watch the stage.
Supported Models
QLab 5
QLab 4
Capabilities
Connection & Diagnostics
Connect to QLab and verify the workspace is online and responding.
Playback Transport
Press GO, stop, pause, and panic your QLab cue stack hands-free.
Cue List Management
Create, delete, move, and renumber cues and inspect the cue stack.
Audio Patch & Spatial Maps
Control QLab audio patch routing and spatial Audio Maps.
System Overrides
Globally gate QLab DMX/MIDI/MSC/network/timecode input and output.
Available Functions
Connection & Diagnostics
Confirm QLab is online and ready before the house opens. Showcaller reads the running version, discovers open workspaces, and runs a live heartbeat so operators know the show machine is reachable.

Playback Transport
Call the whole show by voice. Showcaller presses GO, holds and resumes cues, and hits panic to recover instantly — turning QLab into a hands-free playback engine for live performance.

Playhead & Selection
Stay one step ahead of the show. Showcaller moves the playhead to the next standby cue, jumps to any cue number, and switches active cue lists so the operator is always cued up for the next GO.

Cue Actions
Fire any cue on demand. Showcaller starts, stops, loads, and previews specific cues by number — perfect for ad-hoc playback, rehearsals, and out-of-order recovery during a live event.

Cue Properties
Keep the workspace pristine and performance-ready. Showcaller renames, recolors, flags, arms, and re-targets cues so the stack stays readable and every cue does exactly what the designer intended.

Cue Timing & State
Choreograph timing with precision. Showcaller tunes pre-waits, post-waits, durations, and auto-continue behavior, and reads live cue state so the operator catches broken cues before they hit the stage.

Cue List Management
Program shows faster. Showcaller creates, moves, deletes, and renumbers cues, and inspects cue lists and live playback — so building and reshaping a QLab workspace becomes a conversation instead of a click-fest.

delete_cue_by_id

Audio Cue Control
Mix the show from the cue stack. Showcaller sets crosspoint levels, output routing, playback rate, loop points, and trims directly on Audio cues — dialing in sound design without touching the QLab UI.
set_audio_level
set_slider_level
set_audio_patch
set_rate
set_live_rate
set_start_time
set_end_time
set_infinite_loop
set_play_count

Workspace Management
Run the workspace like a pro. Showcaller saves the show, undoes mistakes, and flips between edit and show mode, so the machine is always in the right state for rehearsal or performance.
save_workspace
workspace_undo
workspace_redo
set_show_mode
set_full_screen
set_always_audition

Fade Cue Design
Design transitions with intent. Showcaller configures Fade cues — absolute vs relative, which geometry properties move, and whether the target stops at the end — for polished crossfades and reveals.
set_fade_mode
set_stop_target_when_fade_completes
set_geo_mode
set_do_opacity
set_do_scale
set_do_translation
set_do_rotation

Video & Geometry
Compose projection like a designer. Showcaller assigns surfaces, layers content, and sets position, scale, rotation, opacity, and effects on Video and Text cues for precise multi-screen storytelling.
set_surface
set_full_screen_video
set_layer
set_opacity
set_translation
set_scale
set_quaternion
set_preserve_aspect_ratio

Text Cues
Put words on the wall instantly. Showcaller writes and restyles QLab Text cues live — updating lower-thirds, lyrics, and announcements mid-show without breaking flow.
set_text
set_live_text
set_text_font
set_text_size
set_text_color
set_text_alignment

Light Cues & Dashboard
Light the show from QLab. Showcaller edits Light cue levels, drives the Light Dashboard live, and records looks into new cues — bringing conversational control to QLab's integrated lighting.

prune_light_cue
toggle_light_dashboard
dashboard_set_light

dashboard_new_cue_with_all

Audio Patch & Spatial Maps
Operate immersive and large-format audio. Showcaller reaches QLab's patch routing matrix and spatial Audio Maps — moving objects, setting mark levels, and managing output mutes for installations and themed experiences.
list_audio_patches
set_patch_crosspoint
set_patch_mute
set_patch_solo
