Tandem Player

1. Open Settings → Enter licence key, paste it, and press Activate. It unlocks on the spot, with nothing new to install.
2. Activation checks the key online once. After that, about once a year, Tandem refreshes the activation by itself in the background while it's open and online, with nothing to click and nothing to pay. If a PC stays offline long enough to miss that, the key's extras pause (everything free keeps working) and come back by themselves the next time Tandem opens with a connection.
3. The key is yours for the versions it covers, on your own machines. If it won't activate, email infinitescripts2@gmail.com with the key.

No. The free edition is the whole player, not a timed trial: your library, every device type, the script strip, the VR player, the CUM button and all thirty shortcuts. A key widens the live controls and unlocks the tools that write to your scripts. The table above is the exact line.

Not unless you ask it to. Depth, reach, speed and custom axes are all applied live on the way to the device and never touch the file. Editing only writes when you press Save, and the first save keeps a .bak of the original next to it. Export doesn't touch the originals at all — it writes new funscript files, one per axis.

Activating a key checks it online once. After that, about once a year, the activation refreshes itself in the background, free and with nothing to click. There's no account, no telemetry and no library scanning sent anywhere. Script sources only ever contact a site you added yourself, and until you add one it contacts nobody.

Yes. Tandem plays companion axis files (name.twist.funscript, name.roll.funscript and so on) as they were written, and a generated axis never covers a scripted one unless you tell it to. The generator is for the other 95% of your library that only has stroke.

SR6, OSR2 and other T-Code devices over USB serial; T-Code over UDP or WebSocket to your own bridge or simulator; anything Intiface/Buttplug supports, the Lovense Max 2 squeeze included; and The Handy (Handy 2 and firmware 4 too) and Autoblow directly. Several at once, all driven together, in the free edition too.

Yes — switch on the remote-control setting in those players and Tandem follows whatever you're watching and drives the device to match. The built-in player is there if you'd rather not run a second app.

For now, yes: Windows 10 or 11, 64-bit. Mobile and cardboard VR are on the list above.

Adding your videos

▶ Watch this part

Click Add folder and point Tandem Player at a folder you already keep. It finds every video, pairs each one with its funscripts — companion files for extra axes such as name.twist.funscript or name.roll.funscript are picked up on their own — makes a preview image for each, and remembers the folder for next time. Badges on each card show what the video has: Script when a funscript was found, an axis badge when extra axes are scripted, VR for headset videos, and the running time. Add as many folders as you like; Folders lets you manage them and Refresh scans again for anything new.

Search, filters and sorting

▶ Watch this part

• Type in the search box and the grid narrows as you type.
• Filter chips (Scripted, Multi-axis, VR, Watched, Unwatched and more): click once to show only those, again to hide them, a third time to switch the chip off.
• Match all needs every active chip, Match any needs just one, and All clears every filter.
• Sort by newest or oldest added, name, length, folder, or at random.
• Watched means you have watched at least a minute of it; right-click a card to change that.

Connecting devices

▶ Watch this part

Connect opens one Connections dialog for every kind of device: SR6 or OSR over USB serial, UDP T-Code, WebSocket T-Code, Intiface, The Handy and Autoblow. Every device type works in the free edition. Connect as many as you like at the same time and playback drives them all together; the toolbar button shows how many are live.

The player and the script strip

▶ Watch this part

• Click a video to open it. The strip under the picture draws the script as a line, coloured from blue when slow to red when fast.
• Click anywhere on the strip to jump there, scroll over it to zoom into a stretch, and double-click to zoom back out.
• Space plays and pauses, the arrow keys skip five seconds, and the axis meters show each axis moving as it plays.
• Drag the divider to give the strip more room (double-click it to put it back), or use Hide script for a bigger picture.

The clean view and fullscreen

▶ Watch this part

Go fullscreen first — ⛶ Fullscreen in the top right, or a double-click on the picture — then right-click it, and everything else goes away: the video and nothing over it, not even the pointer, however much you move the mouse. Every shortcut still works in there — space, the arrows, and the wheel for depth — and right-clicking again brings the controls back. Right-click in a window and the chrome goes the same way, but the pointer stays, which is why the locked view is a fullscreen one.

This is also the short answer to how much of Tandem you can run without the keyboard: the wheel over the picture is depth, pressing the wheel in puts it back to 1.00×, click plays and pauses, and on the script strip you click to seek, drag to select and scroll to zoom. Depth is the control you want mid-session, and mid-session is exactly when no slider is in reach.

Serial and UDP output

▶ Watch this part

Connect device lists the serial ports on your PC, so you can pick the one your SR6 or OSR is plugged into. For UDP, type the address and port your device or bridge listens on (the default is 127.0.0.1, port 7777) and press Send; press it again to stop. UDP is handy for a bridge of your own, a simulator or a preview window.

Stroke shape: depth and reach

▶ Watch this part

Stroke shape changes the motion live, while it plays, and never touches the script file. Depth makes every stroke longer or shorter around its own centre, from 0.3× to 2.5×, so the script keeps its contrast instead of flattening out. Top reach and Bottom reach push the peaks and the low points toward the ends of the range. Set depth with the slider, with W and S, or with the wheel over the picture; pressing the wheel in puts it back to 1.00×. Reset returns everything to the script as written.

Stroke shape from the keyboard

▶ Watch this part

• W and S change depth, E / Q the top reach and C / Z the bottom reach. The wheel over the picture is depth as well.
• The Enabled button switches shaping off and on, and V does the same from the keyboard.
• Reset puts everything back to the script as written; X does the same, and so does clicking the wheel.
• Every key can be changed in Settings.

Multi-axis and custom axes

▶ Watch this part

Multi-axis scripts drive twist, roll, pitch and more, and a meter shows each scripted axis; click a meter to draw that axis on the strip. Custom axes add the motion the creator never wrote: twist, roll, pitch, surge, sway, vibration and — for the Lovense Max 2 — squeeze, all seven at once if you like. Each one can follow the stroke, move only on the up- or the down-stroke, wiggle at the top or the bottom, run at a steady oscillation, or wander at random, with its own range and speed. It never covers an axis the creator scripted unless you tell it to.

Motion presets

▶ Watch this part

A preset is a whole set of custom axes under one name. Apply one and every axis in it switches on at once; A and D step forward and back through them while the video plays, with an Off stop in between, so you can change the character of the motion without opening anything; Customize presets puts a tick beside each one if you would rather those keys walked only your favourites. The built-in presets are there to start from, and you can save your own in Settings.

The CUM button

▶ Watch this part

The big red button ends the motion the moment you hit it: the stroke runs down to the bottom — a fifth of a second at full travel — and stops there, rather than freezing halfway up wherever the last frame left it. To start again you hold it for two seconds, so a stray click never brings the device back on its own. G switches it on and off by default.

Its settings put your own word on the button (it ships as FINISH), record a key of your own for it, and choose whether the motors go limp or freeze in place — limp needs SR6/OSR firmware that understands the release command, and a Test release button tells you whether yours does. You can also give it a climax script of your own that plays instead of a dead stop: your key turns it on, holding that key for two seconds resumes, and G does both.

The region editor

▶ Watch this part

Drag across the strip to select a stretch, then work on just that part. Raise or lower every top or every bottom in the selection, or run Auto range to set them all at once: a fixed value, random within a range, or the existing shape scaled into a range. Undo steps back through it. Nothing is written until you save.

Loop, save and export

▶ Watch this part

Loop the selection and it repeats while you work, so you feel the change before you keep it. Save writes the edit back to the funscript, and the first save keeps a .bak of the original beside it. Export writes the selection out as new funscript files instead, one per axis, leaving the originals alone.

Speed and latency

▶ Watch this part

There are two speed sliders and they do opposite jobs. Device speed, down beside Latency offset, changes how fast the device runs the script, from 0.25× to 3×; the picture plays on at its own speed either way, so at 2× the same passage gives you twice the strokes. Tick Stroke only and only the stroke axis speeds up, leaving twist, roll, surge and any custom axes at 1×. Playback speed, over by the volume, is the one that moves the picture, from 0.25× to 2×, and the script follows it for free. Latency offset shifts the device up to half a second earlier or later so it lines up with what you're watching. Below 1× the device makes fewer strokes, each as deep; tick Speed limit to keep every stroke and cap the speed instead. Double-click any slider to reset it; [ and ] change device speed, , and . change the offset.

The built-in VR player

▶ Watch this part

• The built-in player: open a VR video and press Enter VR. It opens in your headset over Virtual Desktop or Link on your PC, or in the headset's own browser over your Wi-Fi.
• It needs Library sharing, which lets the headset reach your videos over your home network. It switches on when you enter VR and stays on until you turn it off in the VR dialog. While it is on there is no password, so any device on that network can reach your library.

The VR control panel

▶ Watch this part

Press B to bring up the panel, then point and pull the trigger to use it. The bar across the top is a seek bar. The Play page has depth, speed and latency offset, POV, Recenter, volume, and buttons back to the editor or the library. The Motion page adds top and bottom reach and the motion presets — step to one, Apply it, or Clear it again, all without taking the headset off. The CUM button runs along the bottom of every page.

Editing and browsing in VR

▶ Watch this part

The Edit page runs Auto range from inside the headset: switch tops and bottoms on or off, choose Scale, Random or Set and the range, apply it to the whole script or to the selected region, undo, and Save when you are happy with it. The Browse page sets the video format, and Random and Next sit at the top of every page, so you can pick something else to watch without leaving VR.

VR: the sticks

▶ Watch this part

• The controllers work with the panel closed.
• Left stick up and down changes depth; click it to reset.
• Right stick left and right skips ten seconds.

Recentring, the good kind

▶ Watch this part

Squeeze the right grip and let go and the view snaps straight ahead. Hold it and turn your hand instead, and the picture turns exactly as far as your hand does — so the view ends up where you want it, not just where the app thinks the front is.

POV is the left grip: hold it and move your hand forward or back, and the picture comes nearer or further away, following your hand.

VR: the buttons

▶ Watch this part

• The triggers step through the motion presets: the right one forward, the left one back, with an Off stop in between.
• The two face buttons on either controller play and pause and bring up the menu — the left and right controllers do the same things, so it does not matter which hand you reach with.
• Editor ends the VR session and brings you back to the same video on the desktop.
• Every control in here can be remapped to your liking.

Headset apps and script sources

▶ Watch this part

If you would rather watch in DeoVR or HereSphere, the VR button connects to those instead. Tandem Player follows whatever plays in the headset and drives the device to match. Switch on the player's own remote control setting first.

A scene streamed into the headset has no script on your disk. Script sources can ask one site that you add yourself: you type its address, sign in once, and it is set for good. Until you add one, Tandem asks nobody.

Settings

▶ Watch this part

• Default settings: the speed, latency offset and preset every video starts with, and an option to skip ahead to where the script begins.
• Axis output range: squeeze each axis into a range you set, to keep your device off its end stops. A Test button walks the axis to each end so you can check it on the device.
• Presets: your own motion presets, and which ones A and D step through.
• Keyboard shortcuts: the full list of player keys — thirty actions — and you can change any of them.
• Licence: enter or check your licence key.

• 🐢 Slow speeds really slow the device now. Below 1× (down to 0.25×), the device makes fewer strokes over the same passage — half as many at 0.5× — and each one is as deep as the strokes it stands in for. If you'd rather keep every stroke, tick Speed limit: it caps the speed instead, so fast passages get shallower. Its default is in Settings. (every build)
• 🎮 Nine new themes styled after game interfaces. Each one restyles its own controls, which makes 37 themes in all. (with a key)

• 🤝 The Handy 2, and any Handy on firmware 4. Tandem now talks to the newer firmware over the Handy's own v3 connection and works out which route your Handy needs by itself — firmware 3 keeps working exactly as before. If you own a Handy 2, tell us how it goes in the replies. (every build)
• ⏱️ The Handy keeps up with the script. Moves are now sent one at a time, each one finished before the next, and paced to fit the Handy's cloud limit, so it no longer falls behind and catches up in a lurch. In VR it holds its place through the headset's clock corrections instead of stuttering. (every build)
• 📁 A tab for every folder. Across the top of the library there's now a tab per library folder, so you can browse one folder at a time — or All folders for everything together. Settings → Show folder tabs hides the row if you'd rather not have it. (every build)
• 💜 Lovense Max 2: squeeze and vibration, both working. The Max 2's air squeeze has its own Squeeze axis now, separate from vibration, so the sleeve no longer tries to fill and empty eighteen times a second. With no squeeze or vibe in the script, the vibration follows the pace of the stroke and the squeeze breathes slowly underneath it — and both go quiet the moment the video pauses. Squeeze is the seventh custom axis, and exports as its own .squeeze.funscript. (every build; all seven axes at once with a key)

• ⚡ The Handy moves. It was being put into the wrong mode, and in that mode the device refuses every command sent to it — which owners saw as a device stuck at the top, ignoring the output range. Nothing Tandem sent was ever carried out. It asks for the right mode now, checks the answer before it calls itself connected, and says so instead of failing quietly. (every build)
• ✅ Pick many videos at once. Drag a box across the cards or shift-click, then add the lot to a playlist, rate it, tag it or mark it watched in one go. (every build)
• 📺 Videos open in fullscreen. Click a card and it goes straight there — Settings → Default settings has the switch if you would rather it didn't. (every build)
• 🔴 The CUM button lands softly. It used to cut the motors wherever the last frame left them, halfway up as often as not; now the stroke runs down to the bottom first — a full travel in a fifth of a second, the same pace however far it has to come — and stops there. (every build)
• 🔄 A and D reach every preset. On a multi-axis script the keys were getting stuck in a loop of the first few. They walk the whole list now — and Settings → Customize presets puts a tick beside each one, so you can cut the round down to the three or four you want tonight. (with a key)
• 🎨 Make your own theme. Fourteen colours over any of the built-in looks, repainting the app as you drag them. Share turns it into a short block of text — paste it into a reply or a message, and anyone with a key can paste it back. (with a key)
• 🔑 Show and Copy your key in the licence panel, for the day you move it to another PC. (with a key)

Smaller things in the same build: a Library button in fullscreen next to Exit, Add to playlist… in the player's own Settings menu, the device going back to neutral when you jump straight from one video to another, and the hover preview over the script strip no longer freezing on one frame.

Also in v1.1, if you missed it: separate script folders, an axis count that includes the stroke, merged multi-axis files, a lock screen that gives nothing away, and eight new looks.
