Complex Event Programming

Use spreadsheet software to create and edit large effects with many events or complex patterns.

---

Overview

For effects with dozens or hundreds of events, the Leash app supports copy/paste with spreadsheet applications like Google Sheets, Excel, or Numbers. This lets you:

• Edit events in bulk
• Use formulas to calculate timing
• Copy/Paste effect data
• Create complex patterns programmatically

tip

Trying to move an effect to another WOLF ONE or share an effect with someone else? Try Effect Import/Export →

tip

Trying to backup your entire WOLF ONE configuration? Try WOLF Backup/Restore →

Export Events to Spreadsheet

1. Navigate to the Events tab in Leash
2. Click clipboard>copy to copy all events to your clipboard
3. Paste into a spreadsheet application

The data exports as tab-separated values (TSV) with headers.

Edit Standard Events in Spreadsheet

Edit the event data in your spreadsheet:

Column	Description
delay	Event time in microseconds
camera	Camera number (leave empty if using node.port or mono)
mono	Mono number (leave empty if using node.port or camera)
node	Node number (use with port)
port	Port number on node
trigger	ON, OFF (leave empy if using wake)
wake	ON, OFF (leave empy if using trigger)

tip

• Leash automatically reorders events by time when imported
• Leave camera empty when targeting node.port
• Leave node/port empty when targeting camera/mono

---

Import Events from Spreadsheet

1. Select all event data including headers
2. Copy from the spreadsheet
3. Click clipboard>paste and replace on the Events page in Leash
4. Click Save

info

Choose paste and insert to add new spreadsheet events to existing effect events.

Edit Group or Sequence Events in Spreadsheet:

Group event format:

Column	Description	Example
delay	Event time in microseconds	1000000
output_type	camera, mono	C, M
output_range	range, split range, comma separated	(1-100) (1-10,20-40) (1,3,5,7,9)
trigger	ON, OFF	1, 0
wake	ON, OFF	1, 0

Sequence event format:

Column	Description	Example
delay	Event time in microseconds	1000000
output_type	camera, mono	C, M
output_range	range, split range, comma separated, reversed	(1-100) (1-10,20-40) (1,3,5,7,9) (100-1)
trigger	ON, OFF	1, 0
wake	ON, OFF	1, 0
sequencer_type	interval, fps, duration, duration fit	I, F, D, D+
sequencer_value	time, fps, or speed ramped range	1000000, 30, 30-120 (1sec, 30fps, 30fps-120fps)

tip

• Leash automatically reorders events by time when imported
• Leave camera empty when targeting node.port
• Leave node/port empty when targeting camera/mono

---

Example: Bullet Time Sequence

Create a 24-camera bullet time effect with 10ms spacing:

delay	camera	trigger
0	1	ON
10000	2	ON
20000	3	ON
30000	4	ON
...	...	...
230000	24	ON

Use a spreadsheet formula like =A2+10000 to auto-calculate timing.

---

Example: Strobe Sync Events

Add matching strobe events using node.port for each camera trigger:

delay	camera	node	port	trigger
0	1			ON
0		1	7	ON
100000	1			OFF
100000		1	7	OFF
1000000	1			ON
1000000		1	7	ON

---

Tips

• Time values are always in microseconds in the export
• Empty cells are valid - leave camera empty when using node.port
• Headers required - include the header row when pasting
• Validation - Leash validates data on paste and shows errors for invalid entries
