Yamaha SY-55 Music Synthesizer

Excellent Condition

This keyboard came to us as a trade in and is in excellent condition. Of course is it a used keyboard so it has a few small scuffs and scratches here and there but we'd say it's well above average. Everything we know how to test functioned perfectly. All of the keys play properly, the screen is bright and clear we installed a new battery but we didn't have any data cards to test those slots with.

The Yamaha SY-55 was released a year after their TG550 Tone Generator and apart from the attached keyboard, these two share a lot of similarities. The SY-55 is a digital workstation that is based on samples-playback and also one of the first rompler workstations by Yamaha to ditch the DX7 FM synthesis.

It is a 2nd generation 16-bit AWM2 system that makes use of wave data digitally at 32kHz or 48 kHz. The SY-55 also has 24-bit internal signal processing capabilities along with high-res 22-bit digital-to-analog converters. Thanks to its digital filter system, it is possible to shape sound in real-time and it comes with two megabits of sampled waveform ROM for a choice of 74 individual waveforms. With this synth, you get two modes of operation. The first, Voice, allows you to select and play a single sound. The second, Multi, is used for multitimbral setups that you use with the sequencer. In addition, it has a versatile 1,2, or 4-element voice architecture and complex envelope generators to provide users with extensive sample layering capabilities.

In terms of design, the SY-55 features a 61 key keyboard with both velocity and after-touch for expressive control. On the left of the front panel, you'll find the self-centering pitch bend wheel along with the modulation wheel. Above these are the DATA and WAVEFORM card slots while in the middle you'll find the master volume, sequencer keys and indicator, as well as internal, card, and preset keys. The MULTI key and indicator, SEQ key and indicator, as well as 16-character x 2-line backlit LCD panel are also on the front panel. The rear panel consists of the power switch, MIDI In, Out, and Thru connectors, click volume control, Output R, and L/Mono jacks, and phones jack. Here you will also find all the jacks for optional peripherals, such as a Yamaha breath controller, foot switch and foot controller.

Compared to the 16 track SY-77 sequencer, the SY-55 sequencer only has eight tracks but can hold eight songs instead of just one. It has a memory capacity of 8,000 notes, which is half of what the SY-77 offers. The SY-55 also provides 34 fully editable effects, ranging from reverbs and delay to digital distortion and more.

It is important to remember that when buying a used keyboard it may not operate or look exactly like a new one. Used keyboards develop wear over time that can cause such items as function buttons, knobs, sliders etc. to fail to operate as smoothly or easily as when they were new. Our technician does check these items and if they are deemed unusable they are replaced but some function buttons may require more pressure or manipulation to make the appropriate changes. Cosmetically your used keyboard may have scuffs, scratches, cracks to plastic pieces, discolored keys or other visual impairments that might not show up in the photos. We try to mention any obvious visual imperfections but may not consider them serious enough to post in the listing.
