large numbers of these events exist in a sequence. In many cases,

however, many more of these events are output from the keyboard than

are necessary to produce the desired effect.

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 exception—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 dynamics. 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 neighboring

Fixed veloc field (1–127).
