Mini-Sequencer

Mini-Sequencer

The ASSIGNMENTS section of the mini-sequencer is one of its most important sections. It is used to select the 

source of control signals for the two SEMs. 

Each SEM can be controlled by one of the following sources:

•  the keyboard

•  the Mini-Sequencer

•  a sample/hold source

In addition, the keyboard can be used to transpose the sequence when the Mini-Sequencer is controlling one or 

both SEMs.

The Mini-Sequencer functions in three modes:

•  Panel mode

•  Sequence mode

•  Song mode
