AWM Voices and VA Voices 2 The ELS-01C features two different types of Voices: AWM (Advanced Wave Memory) and VA (Virtual Acoustic). Voices VA Voices are available only on the Lead Voice 2 section while AWM Voices are available on all sections except Lead Voice 2. AWM is a synthesis system based on sampled waves, or audio recordings of actual instruments. AWM Voices uses multiple samples, so that they sound like a real instrument. On the other hand, VA synthesis applies sophisticated computer-based "physical modeling" technology to musical sound synthesis. VA Voices in this Electone offer many advantages in terms of musical performance, not just in terms of sound, but also in terms of the behavior that makes acoustic instruments so musical. Driver - generates physical energy Mouthpiece Embouchure Calculates the speed of the resonated air Bow Pipe/strings - simulates resonation Single-ended pipe (saxophone) Double-ended pipe (flute) Strings VA synthesis simulates the very complex vibrations, resonances, reflections and other acoustic phenomena that occur in an actual wind or string instrument. Reference Page Voice Edit (page 127) Notes on VA Voices Since the VA Voices have unique sonic characteristics and are closer in behavior to acoustic instruments than the AWM Voices, you should observe the following precautions when playing VA Voices. • Some Voices may produce unexpected or unnatural sounds when played outside (higher or lower than) the recommended note range (pages 32 and 33). • Pitch change may not be smooth on some Voices when Horizontal Touch is applied. • Portamento (Lead Slide) effects may not be smooth on some Voices. • Keep in mind that playing legato or trills may not produce any sound. 34 ELS-01/01C Owner's Manual
