6. Some advanced features
6.1. Using a bus to control a track
The MBSEQv4 has four buses that can be used to send MIDI data to other tracks. A track sending on a
bus can be used to control the behaviour of another track over the bus for effecting arpeggios and
transposing notes. The controlling track is called the sending track (because it sends data on a bus),
and the controlled track the receiving track (because it listens to a bus for data).
First, it is possible to use the sending track's note data to transpose the notes of a receiving track. A
receiving track in Transposer mode accepts only one note as input. You can send chord data as well –
either as multiple notes or as chord parameter layer entry – but only the last note layer or chord note
will be accepted.
Transpose is relative. This means that if the sending track is controlling two tracks over the same bus,
and the first receiving track has just C-3 notes in it, and the second receiving track has only E-3 notes
in it, changing the sending track's note from C-2 to C#2 will transpose the receiving tracks' notes half
a step upwards – from C-3 to C#3 on the first track, and from E-3 to D-3 on the second track.
Second, it is possible to use the chord data of the sending track to control the arpeggios on a
receiving track. The chord data can be either chord parameter layer data, or it can be data from
multiple simultaneous note layers. For example, if the sending track's chord sequence is C-Am-F-G,
played each quarter note (either as chord track or note track data), the arpeggio patterns on the
receiving track will always include only the notes that the current chord on the sending track
contains. In other words, the arpeggio patterns are determined by the receiving track (the arpeggiator
track), but the notes in the patterns are determined by the chords the sending track plays.
Whether the input is in chord or note layers, the arpeggiator takes the last four played notes as input.
If you play more than four chords simultaneously, the earlier ones will drop out first. Hence, if you
send five simultaneous notes in different note layers, the first note layer will be ignored, and if you
send a chord layer chord that's more than four notes, only the last four notes of the chord will
register.
In both cases (transpose notes or control arpeggios), instead of sending track data over a bus to
control another track, you can use your MIDI controller over a bus to control a track in a similar
manner, so that e.g. the chord you play on the keyboard will determine what the receiving track or
tracks play. For this, see section 6.1.5. for details.
6.1.1. The MODE page
The central settings on the MODE page of each track pertain to tracks that are to be controlled by
another track (or a MIDI controller) over a bus. These are: Mode (off, Normal, Transpose, Arpeggiator),
Bus (1–4), Hold, and Sort.
