Min change
The field is used to thin out the event data for the
above specified event types, thereby reducing the total number of
events that will be recorded into tracks. It works by only recording
events that have changed more than a specified amount since the
last received event of the same type. This amount is set in the
change field. As with the
field shows the value associated with the event type shown in the
Event
field. For example, to thin out incoming channel pressure
events:
Event
1. Set the
2. Set the Pass event?
3. Set the Min change
This means that an incoming channel pressure message will be
recorded only if its value has changed by more than 5 increments
from the last value received. The range of this field is 0-127, with
127 being the full range of the controller. (Pitch bend is an excep-
tion—even though the pitch bend messages actually have a range of
8191, 0-127 represents the full range here. For example, to specify
that only a change of 10% or more in the total range of the bend
wheel may be recorded, enter a 12 here, because 12 is approximately
10% of 127, which here represents the full range of the bend wheel.)
If the Min change value is set too high, a stepping effect will be
heard as the continuous controller is moved. Try to pick a value that
is low enough so that the stepping is not noticeable.
Velocity mode
• The
Incoming MIDI note events are normally recorded into the sequence
with their velocity values intact, permitting the recording of dynam-
ics. These two fields permit the incoming velocity data to be ignored,
if desired, and a fixed value substituted for each incoming note. The
Velocity mode
field has two options:
set to FIXED , all incoming velocity values are replaced by the value
specified in the Fixed veloc
