Hand control is at its best in front of people. An audience cannot see you turn a knob on a controller, but they can see you pull a sound open with both hands. These are the habits that make Tactism dependable once the room is watching.
Light your hands, not the room
Room light matters more than the camera. The tracker needs to see your fingers, so put light on your hands from the front. Ordinary room light works at home. On a dark stage, a small lamp near the camera does more than any camera upgrade. A bright screen or window behind you is the hardest case, since it turns your hands into silhouettes.
Keep your palms toward the camera when you can. The tracker reads best that way.
Frame for your biggest move
Before you play, sweep every gesture you use to its limits and watch the skeleton. If a hand leaves the frame at the top of a raise, move the camera back or tilt it. Span needs both hands in frame at their widest.
Then calibrate. Click CAL, make each gesture as big and as small as you will on stage, and click DONE. Each gesture now fills its whole range at your real reach in that room. Calibrate again at the venue if the camera position changes.
Hold a sound by stepping out of frame
When a hand leaves the camera, its gestures hold their last value. That is the way to hold a sound: find the filter setting you want, drop your hand out of frame, and it stays. Bring the hand back and the dial picks up from where your hand is now, so return close to where you left off for a smooth pickup.
Nothing ever snaps to zero because you stepped away.
Give each hand a job
The two hands are separate lanes, cyan for left and steel blue for right, everywhere in the window. A layout that is easy to remember under pressure: the right hand plays the expressive move (a pinch on a filter), the left hand handles the space (height on a reverb send), and a fist on either side is the switch for the big moment.
Keep the number of live gestures small. Two or three you know well read better to an audience than eight you have to think about.
Shape for the stage
Open SHAPE on each mapping and narrow min / max to the range that always sounds good. On stage, a mapping that can never go too far is worth more than one with extra reach. A fist mapped to a mute or Beat Repeat should have INV set the way your hand expects: clench to cut is the common choice.
Recording
Record the audio, since that is where the performance lives. While a dial is mapped it follows your hands, and Live’s automation for that dial is overridden. When you want automation back on a dial, remove its mapping.
Save the show as a rig
Once a setup works, name it under RIGS. Rigs save on your machine, outside the Live set, and load by track and device position. Build the rig in your show set and it will load cleanly into any copy of that set.
Before you play
- The window header reads “device connected”.
- The skeleton sits on both hands across your whole range.
- CAL was run in this room, at this camera position.
- The Tactism window is open. It can sit behind Live, but closing it stops the camera.
For mapping ideas to rehearse, start with five mappings to try first.
