# basic mode
Furnace comes with a "basic mode" that can be toggled through the "settings" menu. it disables certain features in Furnace that may look intimidating or confusing for newcomers. if you find that a certain feature of Furnace is missing, see if this setting is enabled or not.
among the features that cannot be accessed in this mode are:
### edit menu
- paste special
- operation masking
- input latch
- find and replace
### speed window
- virtual tempo
- divider
- song length
### song info window
- manual system naming
- tuning options
### pattern right-click menu
- gradient/fade
- scale
- randomize
- invert values
- flip selection
- collapse
- expand
### other windows
- mixer
- grooves
- channels
- pattern manager
- compatibility flags

- `D8xx`: **Set volume slide bottom boundary.**
- the default is 0.
- `D9xx`: **Set volume slide top boundary.**
- the default is the channel's maximum volume.
- `DCxx`: **Delayed mute.** sets volume to 0 after `xx` ticks.

- `07xy`: **Tremolo.** changes volume to be "wavy" with a sine LFO. `x` is the speed. `y` is the depth.
- tremolo is downward only.
- maximum tremolo depth is -60 volume steps.
