Dgx 660 chord dictionary6/18/2023 Speakersīuilt in speakers are useful for many home pianists, removing the need for separate amplification, although they do increase the weight and price of the instrument. While not a significant feature on these instruments, there are some basic educational functions on each DGX piano, including the Yamaha Education Suite on the 650 and 660. All DGX-6 series instruments come with reverb, chorus, harmony and master EQ, while later models include DSP (digital signal processing), Intelligent Acoustic Control, Stereophonic Optimiser, and mic effects for those instruments which include a mic in jack. EffectsĮffects can provide interesting sound altering and enhancing capabilities. The number and scope of accompaniments increases on newer models. The accompaniments will not rival that of Yamaha’s arranger keyboards, but still provides a useful base for both performing, composition and musical inspiration. This is something not found on higher end professional digital pianos, suggesting these instruments are aimed more at beginner to intermediate players or those for whom live performance in a band or solo artist situation is a requirement. AccompanimentsĪll the keyboards feature an accompaniment/rhythm section which can be triggered and used to play harmonising chords. This means a feel more akin to that of an acoustic grand piano, with lower register keys feeling heavier than higher ones. KeysĪll six instruments feature 88-keys with Yamaha’s popular Graded Hammer Standard (GHS) keyboard. In any case, it is fair to say that the piano sounds will not have been compromised simply by having more onboard sounds. It is up to the individual musician to decide whether these additional sounds are required. The number of non-piano sounds also increases with model. It’s worth noting that much of this can be used with the increased number of accompaniments, voices and effects available on later models, although the benefit is most definitely felt when playing the grand piano instrument. This rises through the series to the DGX-670 which has a maximum 256 polyphony. The DGX-620 has a meagre and rather inadequate 32 note polyphony. The DGX-650 and DGX-660 use Yamaha’s Pure CF Sound Engine, while the latest DGX-670 uses a Yamaha CFX sample base and VRM sound modelling. AWM (Advanced Wave Memory) and its related successors has been common on a lot of Yamaha digital pianos. Yamaha doesn’t mention the sound technology used for the 620, 630 and 640 models except to say that it uses “sampling” or “Live! Grand Piano Sound”.
