Description

Triggers a series of line segments between specified points.

Syntax

ares triglinseg kTrig, ia, idur1, ib [, idur2] [, ic] [...]

kres triglinseg kTrig, ia, idur1, ib [, idur2] [, ic] [...]

Initialization

ia -- starting value.

ib, ic, etc. -- value after dur1 seconds, etc.

idur1 -- duration in seconds of first segment.

idur2, idur3, etc. -- duration in seconds of subsequent segments.

Performance

kTrig -- trigger value. Will trigger playback of envelop when kTrig is equal 1

These units generate control or audio signals whose values can pass through 2 or more specified points. The sum of dur values may or may not equal the instrument's performance time: a shorter performance will truncate the specified pattern. Triggering the envelop while it is already playing will cause the envelop to jump to the start and play again. This might cause a pop or a click. It is best to wait till the envelope has ended before retriggering it.
