[. . . ] Deals with the necessary preparation before using, including connections to other components, such as instruments, mixing consoles, patchbays, and multitrack recorders. A detailed look at the signal processing capabilities of the MidiVerb 4 and the concept of multi-effect programming. A guided tour for programming typical single and multi-effect applications. Use this chapter as a quick reference guide when searching for specific information. [. . . ] The Hold Time determines how long the gate will be held open before it begins to turn off; this can be set from 0 to 500 ms. The rate at which the gate closes is determined by the Release Time, which can be set from 0 to 500 ms. In the case of the Chorus->Room, Flange->Room and Room->Flange Configurations, only one parameter is available: Gate. This can be set between 10 and 500 ms, and controls both the hold and release times of the gate effect. Alternatively, the Gate parameter can be set to "OFF" when you do not wish to use the gating effect. 32 MidiVerb 4 Reference Manual Overview of Effects ­ Chapter 3 Delay Effects Delay provides a discrete repetition of a signal. By adding feedback within the effect, the delayed signal can repeat many times, with each successive decay softer than its predecessor. Each of the Delay types allow you to adjust their delay time in milliseconds, however, the BPM Delay effect will display the equivalent musical tempo in BPM (beats per minute). MidiVerb 4 offers the following types of delay: Mono Delay This Single Configuration provides delay of signal up to 1299 ms. The delay time can be adjusted separately by 100ths, 10ths and 1 ms increments. You also have high and low frequency cutting, which gives you the ability to equalize the effect's decay. This can help emulate an old tape-style echo where each succesive echo is darker than the previous one. Stereo Delay This Single Configuration provides two separate delays which can be individually adjusted for delay time, feedback and high and low cutting. This can be done in two ways: · · Hold the button which corresponds to the Tap parameter; or Hold down the footswitch (if the Footswitch parameter is set to the Control function). While using either of these methods, feed signal to the MidiVerb 4. This could be done by hitting a drum, plucking notes on a guitar or keyboard, or by singing some "doot doots" into a microphone (depending on what is connected). Note: When the Footswitch parameter is set to the Control function, you can control tap tempo as described above while in either Program mode ([PROG] button lit) or Edit mode ([EDIT/PAGE] button lit), unlike when using the front panel for tap tempo which requires that you be in Edit mode. For more information on connecting a footswitch and selecting the Footswitch parameter's function, see Chapter 2. 34 MidiVerb 4 Reference Manual Overview of Effects ­ Chapter 3 Pitch Effects The Pitch effects alter the pitch of a signal in various ways to produce "layered" timbres that are more complex than the original signal. Although some of these effects can sound similar to one another depending on the parameter settings, each is achieved differently and can be quite dramatic under the right circumstances. Pitch effects are achieved by splitting the signal into at least two parts, effecting the pitch of one of the parts, then mixing them back together. This eventual mixing is essential since the overall sound of the effect is achieved by the actual difference between the dry, uneffected signal and the effects signal. The various types of Pitch change are: Stereo Chorus The Chorus effect is achieved by splitting the signal into three parts with a dry signal and a separate Detuning section for both left and right channels. When the left channel is detuned sharp, the right is detuned flat, and vice versa. The detuning is further effected by being modulated by an LFO (low frequency oscillator) which causes the detuning to vary. Many variables are available in this scheme: the Predelay can be varied, the LFO depth can be varied, the LFO speed can be varied, and a portion of the detuned signal can be fed back to the input to increase the effect.
