The 

Min change

 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 

Min

change

 field. As with the 

Pass event?

 field, the 

Min change

field shows the value associated with the event type shown in the

Event

 field. For example, to thin out incoming channel pressure

events:

1. Set the 

Event

 field to 

CHANNEL PRESSURE

.

2. Set the 

Pass event?

 field to 

YES

.

3. Set the 

Min change

 field to 5.

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.

• The 

Velocity mode

 and 

Fixed veloc

 fields:

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: 

NORMAL

 and 

FIXED

. If

set to 

FIXED

, all incoming velocity values are replaced by the value

specified in the 

Fixed veloc

 field (1-127).
