Mode 3: Groovebox Live Sequencer  

Groovebox mode is the most sophisticated feature of the Synthino XM. It is a "live" 16­step 
sequencer which allows you to lay down 4 different tracks by playing a MIDI controller. For 
simplicity this mode does not have secondary functions on the controls. 

 

When the sequencer is running, any MIDI note or drum sample you play will be recorded to 
the current track and repeated as the sequencer runs. You can simply play different notes to 
record over what is currently recorded on the the track. Each track has independent envelope 
(

attack

release

) and volume. Each note can have a different 

waveform

, even on the same 

track. The waveform recorded is the waveform that was selected when the note was played. 
Using MIDI channel 10 is a great way to lay down a drum track, since channel 10 MIDI notes 
are mapped to various percussion samples (i.e. the waveform setting is ignored).

track select

: Choose which track you are editing. The LED indicating track 1­4 will blink 

momentarily when you change tracks. Try this first with the sequencer stopped. The incoming 
MIDI channel number does not matter (except in the special case of channel 10 drum 
samples).
