TEMPER glossary
Every control is listed under the page and card it lives on, in the plug-in’s own words. Where a control shows words rather than numbers, its two ends are given.
Conventions
- Knobs read their value in words, with their two ends written under them. Drag to change a value; hold Shift for fine steps; double-click to restore the default.
- Hidden controls. A control the sound does not use is not shown. Its value stays in the program.
- More on a card opens a drawer with the rest of that part’s controls.
- Ranges below are what the control offers; each program sets its own starting value.
Header
Preset box. The family and program number over the program’s name. Click to open the Library; ‹ › step through programs. A dot before the name marks unsaved changes.
SCALE. The tuning in force, 12-TET by default. Opens the tuning menu: Load scale (Scala .scl or Ableton Live 12 .ascl), Load keyboard map (Scala .kbm), Clear, A4 Reference (400–480 Hz) and Follow (Auto, Preset, Scala or MTS-ESP).
QUALITY. Eco, Normal or High. Higher quality resolves more detail for more CPU.
TUNING. Anchored keeps each note on its target pitch; Free lets the body pull the pitch.
Volume. The output level, −60 to +6 dB.
Instrument / Stage. The instrument’s page, or its section on the Stage. The Stage tab appears on programs that can play as a section.

Playing card
The card is named for what plays the note: Finger, Pick, Nail, Tsume, Bow, Hammer, Mallet, Breath or Rattle.
| Control | Range | What it does |
|---|---|---|
| Pluck / Strike / Bow | choice | How the note is played. A bar, plate, drum or bell offers Strike and Bow. |
| Finger / Pick / Nail / Tsume | choice | The plucking tool. |
| Yarn / Rubber / Wood / Metal | choice | The mallet’s head. |
| Touch | soft to hard | How hard the finger, pick or mallet is. |
| Strength | gentle to strong | How strongly the note is played. |
| Pressure | light to heavy | The bow’s weight on the string. |
| Speed | slow to fast | The bow’s speed. |
| Release | stopped to let ring | What your hand does when you lift the key, on plucked and bowed strings. |
| Where | bridge to middle | Where along the string the note is played. |
| Palm mute | off to full | A hand resting on the strings. |
| Strike point | centre to edge | Where the mallet lands on a bar, plate, drum or bell. |
| Macros | 0 to full | The program’s four macros, each named for what it does. A wheel mark shows a macro the mod wheel also turns. |
More opens the playing drawer: the action, its strength and touch, how velocity sets strength, touch and release, and switches such as Input (audio from your host plays the held notes) where the program offers them.
Picture
The instrument. A photoreal picture of the program’s own instrument, with the point where the note is played. Drag it to move the pluck, strike or bow point. Right-click, or press Command-Shift-M, to reduce motion.
Rings. How long the note rings, short to long, in words such as about 5 seconds.
Tone. How bright the note is, dark to bright.
Instrument card
The card is named for the part that sounds: String, Bar, Plate, Gong, Cymbal, Drumhead, Bell, Bowl or Hybrid.
| Control | Range | What it does |
|---|---|---|
| String or Material | menu | What the string or surface is made of. |
| Ring | short to long | How long the note rings. |
| Tone | dark to bright | How bright the note is. |
| Body | dry to resonant | How much the instrument’s body resonates, on a string. |
| Shimmer | none to full | A slow shimmer in the ringing, on a surface. |
| Glide | down to up | A pitch that slides after the strike, as on a drum. |
| Sympathetic strings | on or off | Extra strings that ring along with what you play. |
Material pad
Material X / Material Y. The point on the pad, blending between the program’s four named corners. Each axis is named, such as Touch and Mute. The lower-left corner is home, the program as voiced. The mod wheel moves Material Y. The words under the pad say where you are, such as Mostly open, some muted.

Keyboard strip
| Section | Controls | Range |
|---|---|---|
| KEYS | ‹ C1 – C6 › | The five octaves shown, by octave. |
| TRANSPOSE | Semitones, Fine | ±24 st; ±100 ct. |

The keys play at the velocity of the height you click. The pitch wheel springs back; the mod wheel stays where you leave it. On a section, each lit key shows how many players are on it.

Drag a source’s coloured header into the Patch to route it. Drag the points on its display to shape it.
Patch
Route. A cable from a source to a target, up to 16. Its thickness is the amount; drag it to change the amount. Click it to set:
