LOGICAL operations: Once the conditions relating to intervals and events have been selected as
described above, one can decide what operations to perform.
OPERATIONS on events (RESULT fields): All events satisfying the conditions relating to the
operational interval and the conditions relating to their values can be transformed as follows:
STAT: Status transformation. The status will be transformed into the one shown in the left-hand
box; therefore, a note event can become, for example, a control event. If the status is not chan-
ged, there will be no transformation of events, i.e. notes will remain notes, etc. We suggest not to
change the result status unless specific sound effects are desired.
1 (1st): By selecting this field you can perform operations such as addition subtraction equality. For
example, in the case of STATUS NOTES, you can transpose the notes by one octave upwards by
entering [+] (addition) and entering 12 (amount that will be added to the notes) in the value
box. If None is selected, no operation will be performed on the first byte of the event.
2 (2nd): By selecting this field you can perform operations such as addition subtraction equality.
For example, in the case of STATUS NOTES, you can change the velocity of the notes
downwards by 10 points by entering [-] (subtraction) and value 10. If None is selected, no ope-
ration will be performed on the second byte of the event.
CH (Channel): You can change the midi channel of the events by entering for instance the value
16. All the events that satisfy the set conditions will take up midi channel 16. If None is selected,
no operation will be performed on the channel of the event. Contrarily to the other functions,
this one does not allow you to choose any of the three operations -/+/=; in fact, the = sign is
fixed. You can only choose the midi channel.
LEN (length): This is valid only for note events. For example, you can “stretch” the duration of a
note by one quarter by entering [+] and [0 1 0]. You can give the notes a fixed duration of 2
quarters with [=] and [0 2 0]. If None is selected, no operation will be performed on the duration
of the note event.
QUANTIZE: Use F6 to select the quantization value and press F10 (Execute): the events will be
quantized.
EXTRACT: Press F7 for selection and then F10 to execute: the events will be moved from the run-
ning track to the first available track.
COPY: Use F8 to select the function and then use F10 to enter the end position in the COPY POSI-
TION box: starting from the position set in COPY POSITION, all the events will be copied.
DELETE: Use F9 to select the function and then press F10: all the events will be deleted. The
Quantize, Extract, Copy, Delete operations take place
according to the conditions set in the upper part of the
display and they do not take into account the Result
part. The Copy function, as mentioned earlier, takes
into account also the parameter that is in the lower
part of the “Copy Posit” display.
