Float Sequence 🕒🅡🅣🅝

Float Control is great when you want a smooth wave, but sometimes you don't want a wave - you want to hit exact values in exact order. That's what Float Sequence is for. You type a comma-separated list like 0.0, 0.5, 1.0, 0.25, it cycles through them on a timer, and outputs the current one as a FLOAT. If Float Control is an LFO, this is a step sequencer.

The sequencing model is straightforward: steps_per_item says how many frames to hold each value, and sequence_mode says how to walk the list. forward goes 0, 1, 2, 3, 0…; reverse goes backward; pingpong bounces at the ends (0,1,2,3,2,1,0…); and random jumps around. The node keeps state between executions - current index, a step counter, and a direction flag for pingpong - and only advances the index when the step counter hits steps_per_item. So at 30 steps per item and 30fps, each value holds for one second. Set it to 1 and it changes every frame.

This is the node for the "strict choreography" side of real-time work. Want a brightness that jumps between 0 and 1 on a beat? That's 0, 1 with a short steps-per-item. Want a three-stage effect that evolves like a scene change? List the stages. Because the output is a plain float, it plugs into anything numeric - same as Float Control, but with your values instead of a waveform's.

The inputs that matter

• values - the comma-separated list. 0.0, 0.5, 1.0 is the default; whitespace around the commas is tolerated.
• steps_per_item - frames per value. This is your tempo control.
• sequence_mode - forward, reverse, pingpong, or random.

Output: one FLOAT.

Install & notes

It's in ryanontheinside/ComfyUI_RealtimeNodes - ComfyUI Manager (search "Control Nodes") or:

cd ComfyUI/custom_nodes
git clone https://github.com/ryanontheinside/ComfyUI_RealtimeNodes
cd ComfyUI_RealtimeNodes
pip install -r requirements.txt

Keep always_execute on, same as every control node in this pack - the sequence only advances because the node re-executes each frame. The one trap is the "random" mode: it uses a step counter too, so it only rolls a new value when the counter rolls over; it doesn't re-randomize every frame. And remember the values are floats you typed by hand, so if the list has a typo, the parse throws right there in the node. If you need a sequence of whole numbers, use the sibling Int Sequence instead - it's the same node with integer semantics.
