Midi Commands - Viscount Allegro Operating Manual

MIDI messages trasmitted and received from the Allegro
The MIDI data (messages) which your Allegro transmits and receives are the following:


Note and Velocity Data
Data of this kind instruct the receiver keyboard or the sound generator to play a certain note
(specified by the MIDI note number) with a certain dynamic level (specified by the MIDI Velocity
value). The Note and Velocity data are transmitted by the Allegro whenever a key is pressed;
Allegro's internal sound generator will play the corresponding note or notes in the same way
whenever the note and velocity data are received from an external MIDI device. There is also
the poly-timbric feature, which means that if more than one section (two or three) is set on the
same MIDI channel, when the MIDI note is received the sections connected to that channel will
all keep playing the same note.


Program Change Data
The Allegro transmits a MIDI program number between 0 and 127 when the relative key is
pressed (see next chapter). Normally, this will lead to selection of the timbre of the same
number on a receiver MIDI device. The Allegro responds in the same way, by automatically
selecting the appropriate timbre when a MIDI Program Change code is received. See the next
chapter for information about the commands to be used with regard to Program Changes.


Control Change Data
The Control Change data refer to the operations relating to the controls (e.g. the Soft,
Sustain and Damper pedals) and are transmitted by the Allegro when the controls are used. If
the receiver device is a sound generator or another keyboard, it will react in the same way as
the Allegro's internal generator if a pedal is used. The Allegro also receives and responds to the
appropriate Control Change data. Refer to the next chapter for information on setting the
Control Change filters.
