APPLICATIONS Stereo From a Mono Source Delay the sound to one of two speakers using the E1005 in long delay range, at about the minimum delay setting. The delay is long enough to spread the image and enhance the ambience. This type of stereo spread is not recommended when the program is also being combined to a mono signal, since phase cancellations might be objectionable in the combined signal. Automatic Double Tracking True double tracking can be obtained by overdubbing the exact same instrumental or vocal part on a second track of the tape. The sound achieved is never in perfect unison due to minor variations in pitch and time. Double tracking is a very desirable and useful effect (also known as chorusing), especially for richening the sound of vocals, strings, and other instruments. The E1005 creates this effect automatically in real time, allowing you to precisely control the variables (pitch and time deviations). The delay is set in the long range, at minimum setting, and is automatically increased and decreased by the E1005's built-in Modulation controls (Speed and Depth). Echo and Reverb Effects "Echo" and "reverb" are often confused with one another, and there is some overlap in their definitions. Generally speaking, "echo" consists of one or more distinct, delayed sound images with recognizable attacks. "Reverb" also consists of multiple delayed sound images, but they smear together and have no discretely discernable attacks. To get a single echo from the E1005, set the Feedback control at zero, and adjust the time delay as desired. For multiple echoes, turn up the Feedback control. If the input program has little or no sharp musical attacks (i.e., legato string lines or melodic vocal backups), then the multiple echoes with a long delay time can sound like a reverb. When there are more sharp attacks and decays in the program material, the effect will seem more repetitive. Vibrato Vibrato, while it is a pitch change function, may be created with the El 005 analog delay line. The E1005 can thus add vibrato to voice or instruments which could not easily achieve the effect acoustically, or it can increase the amount of natural vibrato. You can use the El 005 to vary the pitch manually by moving the Delay time control back and forth, or you can set the unit for automatic pitch variation by means of the Modulation Speed and Depth controls. Flanging The E1005 creates flanging effects automatically and repeatably. The effect is obtained by setting the unit for a Short delay time, using Modulation, and Mixing the direct and delayed sounds together; the varying delay signal interacts with the direct signal to create changing phase cancellations that sweep across the various overtones. Machine Voice and Vocoder Type Effects The El 005 can make normal voice or instrumental parts sound like they are coming from a hollow cavity or tunnel. This is done by setting the unit for a short delay, and by Mixing the direct and delayed sound. This is similar to flanging, but there is no Modulation so the result is a hollow-sounding comb filter. If the Delay time is increased slightly and Feedback is added, then more of a tunnel -like sound (flutter-echo) is obtained. Rhythmic Effects Unusual rhythmic effects can be obtained by setting the E1005 for a particular delay, usually long, and playing against it. Thus, there is a direct interaction between the performer and the sound equipment. Whole musical pieces can be built around this interactive principle, e.g., rounds and cannons. Pitch Bend with Feedback In contrast to vibrato, which is a gradual and linear variation in pitch, it is possible to obtain sequenced changes in pitch by using the Long delay range, Feedback, and gradually changing the Delay time (manually or with the Modulation controls). A similar effect is obtained by moving the Delay control up or down and then holding the new setting; the pitch will increase or decrease, then hold at the new pitch until the delay dies out or a new sound is introduced. 8
