Chapter 11: MIDI Function

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).
