yamaha sy77 (1989) FM + AWM "music synthesizer"

OVERVIEW


The SY77 is a multitimbral, Advanced FM plus AWM workstation, modestly described on the front panel as a 'music synthesizer'. It has the widest range of potential sound-producing capability I have ever witnessed in an 'affordable' instrument - from fully synthetic to breathtakingly real, all in very high quality stereo (or even quad, for those who remember it!). In the past it has always been necessary for musicians to acquire a mixture of different methods of producing sounds (analogue, sampled, digital, etc), but the SY77 makes that approach virtually redundant. Imagine an instrument which has the potential to sound like a D50 LA synth, an M1 AI synth, a U20 using Resynthesized PCM, a Phase Distortion CZ synth, a K5 Additive synth (with up to 32 harmonics), a Clavinova, a DX7, an Oberheim or Prophet Analogue synth, a CS80 using Ring Modulation to warp sound, and more - plus any mixture of these, and some new ones! It looks like I don't need to wait for a Resynthesizer [see SOS Feb 88] - the SY77 can sound like almost any keyboard, and it is here now!

The SY77 I (and other reviewers) have been using is a prototype version, not a fully finished production line model. Therefore some of the functions I am about to describe may have changed slightly in the final design. The factory sounds will probably be different, so I will not concentrate on those which came with the review instrument. The owner's manual was not available for most of the (short) review period but I unearthed no glaring problems, despite some serious exploration of the SY77's quieter back-alleys. The machine has never crashed, and has performed flawlessly in almost every respect - and this was only a prototype! Production models will be available in late January/early February 1990.

NEW YAMAHA MEGA-SYNTH


Yamaha have launched a major new flagship synthesizer, the SY77 (£1999), as the first of what could be a whole new generation of Yamaha products. The SY77 represents another significant step forward in synthesis technology, in the same way that FM and LA did — old style 6-operator FM has been kicked into touch, and superceded by a technique called Realtime Convolution and Modulation (RCM) synthesis. The technique incorporates Advanced FM (AFM) synthesis and AWM2 sampling capabilities, but within an architecture that allows them to interact - the characteristics of a sampled sound can be used to modify those of a synthesized sound.

The SY77 is 32-note polyphonic, 16-part multitimbral, and includes on-board drum sounds, digital effects and a 16-track sequencer.

Also new is the TG55 tone module (around £699), which has the AWM2 voicing facilities of the SY77 but no AFM and no RCM. The TG55 is 16-voice polyphonic, 16-part multitimbral, and offers onboard digital effects.

AWM2 sampling technology is a refinement of the Advanced Wave Memory found on previous Yamaha instruments. Samples are stored with 16-bit resolution, and all are sampled at 32kHz or 48kHz. Internal processing is 24-bit, output is via 22-bit digital-to-analogue convertors, and 4Mb of samples are stored internally. Additional waveform data can be read from ROM cards; one ROM card slot is dedicated to waveform data, another to program data.

The Advanced Frequency Modulation uses six operators, which can be configured in 45 different algorithms. Each operator can use any of 16 different waveforms, and any algorithm can include up to three feedback loops. RCM involves using AWM2 elements to modulate AFM operators. Each AWM2 and AFM element in an SY77 voice has two 12dB per octave real-time digital filters, a significant addition to FM. A full review of the SY77 will appear in next month's Sound On Sound.
