It is possible to assign effects to executors. 

If an effect is assigned to an executor, the information regarding the effect is displayed in form of an effect mini executor. 

**Important:**\
However, this only works using selective effects. 

To assign an effect to an executor:

1. Press Assign and tap an effect in the effect pool.
2. Then, tap an executor.
3. The effect mini executor is displayed in purple.

_Selective effect assigned to an executor_

Much the same as other mini executors, the effect mini executor is divided into different sections. For more information on the general sections see [Sequence mini executor](/grandma2/key_cs_sequence_mini_executor/).

## Sections Corresponding to the Effect Mini Executor

The third line (displaying BPM) and the forth line (displaying s) correspond to the speed master.

Speed master in an effect assigned to an executor

- **BPM** corresponds to the executor time that is applied to the effect as a factor. 60 BPM correspond 1:1. 

**Important:**\
If you tap the upper area of the mini executor, the [assign menu](/grandma2/key_exec_assign/) opens.\
Tapping the lower area of the mini executor opens the [effect editor](/grandma2/key_effects_predefined/#effect_editor).

Generally speaking, the speed of an executor influences the speed of an effect. For more information on the speed master in an executor see [Speed Masters](/grandma2/key_adv_exec_spec_master_speed/). 

**Important:**\
The master of an effect executor affects the size of an effect. 

- **s** corresponds to the master fade time that is applied to an effect when turning it on or off. 

**Important:**\
Speed groups only work if they were assigned to the executor and not the effect itself.
