To change thestatus of a particular event, first select the event in the Eventfield, then set the Pass event? field to the desired status—YESor NO.COMMENT: An example of a good use of this function is toprevent channel pressure data from being recorded into yourtracks. If you are using a keyboard that produces channelpressure messages, all of these continuous messages willnormally be recorded into the track, whether your synthesizeruses them or not. This will cause a lot of extra sequencememory to be used and will cause the sequencer to workmuch harder to play all of these messages, possibly causingnote delays. To avoid this, turn off the recording of continuouscontroller messages unless your synthesizer is usingthem. To do this, select CHANNEL PRESSURE in theEvent field, then select NO in the Pass event? field.• The Min change field:This field only appears if the Event field is set to PITCH,CHANNEL PRESSURE, MIXER VOLUME, MIXER PAN,OUTPUT/EFFECT LEVEL, or controllers 0 through 31. These areall continuous controller event types, meaning that large numbers ofthese individual events are used to simulate a gradual change in thespecified parameter. For example, when you move a pitch bendwheel on a keyboard, a large number of pitch bend events areoutput from the keyboard, and all of them are recorded into theactive track. The problem with recording all of these events is thatthey use a large amount of memory and they cause the internalcomputer to work very hard, causing possible timing delays if largeamounts of these events exist in a sequence. In many cases,however, many more of these events are output from the keyboardthan are necessary to produce the desired effect.Page 214
