Its history, however, can be traced back 60 years to when electronic organs were first making their appearance. Actually, an electronic organ is a type of synthesizer. It differs from modern synthesizers, though in the sense that an electronic organ can only reproduce one type of sound, while a synthesizer can reproduce many different sounds. Today’s synthesizers can sound like anything from a siren to a cello. Each sound can be modified in several ways. While electronic organs can produce sounds somewhat similar to other instruments, a synthesizer produces sounds which sound exactly like the originals. And with a synthesizer, you play melodies instead of just single chords. Electronic organs were developed with the limited technology of the time along the patterns of conventional pipe organs. Synthesizers are the product of much more modern electronic knowledge, and as a result are as different from organs as guided missiles are from bi-planes. The first synthesizers were huge. Some even filled entire rooms. As the science of miniturization developed, the same capacity synthesizers were reduced in size. Today, they are completely portable and many can be easily carried by a single person. One of the most important features of synthesizers is their ability to alter timbre, tone and performance effects without changing the base tone. On advanced models, like Roland’s SH-2000, you can even vary volume, tone and special effects by finger pressure on the playing keys. No other musical instrument today has the depth and range of sound that synthesizers do. Modern music depends on the synthesizer for much of its effectiveness. In fact, without the synthesizer, much of today’s experimental and modern musical forms would not be possible. Types of synthesizers At present, there are several different types of synthesizers. Some are only for studio use, others are ultra-portable. Among the portable types, there are three basic classifications: 1) Variable synthesizers (Roland SH-3) 2) Preset synthesizers (Roland SH-2000) 3) Variable/preset synthesizers (Roland SH-1000) The first type is most often used for jazz and combo performances or recording. The second type is most often used in combination wtih an electronic organ. The third type is designed to combine the features of both. How to get the most effective use from a synthesizer Like all electronic instruments, the synthesizer is connected to an auxiliary amplifier. The SH-2000 can be connected directly to an electronic organ, however, and use the organ’s amplifier for operation. With different devices, different effects can be created with a synthesizer for even more unusual or special sounds. The most common accessory devices used with synthesizers is the echo chamber. The Roland RE-201 is one of the most popular units of its type on the market and is designed to complement the performance of all Roland synthesizers. With their unique ability to recreate and modify virtually any sound, synthesizers have opened up a new world of musical excitement, and are playing an increasingly important role in the creation of new music. Roland is proud to be part of this dynamic experience by being able to provide musicians with the most advanced units on the market today. 30 different kinds of preset sounds for full variety . . . There are 21 preset instrumental sounds and 9 special sounds, totaling 30 preset setting tablets. Any preset sound can be produced by pressing just one tablet. This rich variety of preset sounds will extend your musical repertoire and enhance the quality of even the simplest melodies. Touch effect for pinpoint variety . . . TOUCH EFFECT CONTROL on the panel automatically gives 6 different kinds of performance effect. VOLUME, WOW, GROWL, VIBRATO and PITCH BEND UP-DOWN are temporarily available throughout a performance by merely applying slightly more pressure when pressing the keys. This special effect is not possible with conventional electronic organs and allows endless inspirational variations of preset sounds. Free sound variations based on preset sounds . . . FILTER CONTROL for modifying or completely changing the preset sound itself, PORTAMENTO for drifting a tone to a following tone without any break in sound, TRANSPOSE SWITCH for raising or lowering the tone by one octave with a single touch, RANDOM NOTE for producing random sounds having no relation to the pressed key. HOLD for maintaining sounds after key is released, LONG SUSTAIN for sustaining and slowly extinguishing sounds after key is released, and REPEAT for repeating sounds consecutively at regular intervals are conveniently arranged for use at one touch of a tablet. With these functions, free variations of an infinite variety can be created using the 30 preset sounds as a base.
