Volume (Databyte
2 of Note On events)CTRL-L
This functions allows you to change the Databyte 2 values of existing
Note On events (also known as Velocity, see Databyte
2 of a Note On event inside the MIDI editor) inside a previous
made selection.
The highest possible MIDI volume value is 127, the lowest 0. The
MIDI specifications define that if the volume value 0 is set inside
a Note On event, this event is not a Note On - it is a Note Off
event. Note Off events tell a MIDI device, that a previous started
Note stops. MIDI Locator prevents you from setting Note
Off events by featuring the notelength value inside Note On settings.
Because a Databyte 2 of 0 would transform a Note On event to Note
Off, a value of 0 will actually be set to 1, if committing the
volume change by the OK button.
There are two main modes in which you change the volume of your
MIDI events :
1. Linear
Linear means that all events in your selection will be set to
the same value.
Set a mark in the check box linear.
Volume dialog with selected
linear mode
Use the field volume linear for specifing the value you
want to set.
2. Not linear
Not linear means that you can fade in or out from
any starting value to any destination value (beween 0 and 127)
by an exponential function. You don't have to care about the internal
mathematical function, you only have to adjust the curve on the
screen.
If you want these not linear definitions of volume's curve
release the mark linear.
Volume dialog without
selected linear mode
In this mode you can touch and move the 3 little green points
on the curve. The 1. and 3. are the start and end value, so they
can't be moved into the inner screen. The volume linear field
is not needed in this mode, so this field is dimmed.
The fix / relative button
Use this button (1) to toggle between the fix and releative volume
calculation. The fix mode was explained in the upper description,
relative means that the old volume in your event is used
to calculate the new volume.
Volume dialog showing
relative mode
MIDI Locator calculates the new volume by a percent
expression which reaches from -100 % to +100 % (2). -100 means
old value minus 100% = low it down to silence. +100 means power
it up to its double amplitude.
The relative calculation of the new volume can be done in both
the linear and the non linear mode.
