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.
