Yamaha TG77 Tone Generator

   (0 reviews)

The Yamaha TG77 synthesizer features: Realtime Convolution and Modulation (RCM); AWM2 - 16 bit linear waveform data, maximum 48 kHz sampling frequency; AFM - 6 operators, 45 algorithms, 3 feedback loops, 16 waveforms, modulation from AWM output; Filter - Time variant IIR (infinite impulse response) digital filters, 2 filters for each element (maximum of 8 filters per voice); Maximum simultaneous notes - 16 notes AWM + 16 notes; Maximum Simultaneous Timbres - 16; Note Assignment - Last note priority, DVA (dynamic voice allocation), SVA (static voice allocation).

AWM2 (second-generation 16-bit Advanced Wave Memory)

Unmatched sample playback quality.

AFM (Advanced Frequency Modulation)

Advanced FM sound quality and programming versatility.

RCM (Realtime Convolution & Modulation)

Achieves a new fusion of sample realism and the expressive power of FM.

New Concept in Voice Architecture

Versatile 1, 2, or 4-element voice architecture and complex envelope generators for extensive layering capability.

Advanced Digital Features for Dynamic Timbre Control

Two advanced digital convolution filters are available to each voice element.

Dynamic Panning for Lively Stereo

Allows the output from each element to be moved across the stereo sound field in many ways from simple sweeps to complex motions. Panning can also be controlled via velocity, note number or LFO control. A bank of 64 preset pan memories is provided in addition to 32 programmable locations for for user pan patterns.

Built-in Effects Add Essential Ambience

Direct access to four essentially discrete programmable effect processors, two for reverb effects and two for modulation. Selected reverb effects will allow separate parameters to be programmed for the left and right channels. The separate effect processors can be interconnected in several ways providing a wide range of sophisticated parallel and series processing configurations.

Comprehensive Display and Data Entry Controls

A large 240 x 64 dot backlit LCD panel simplifies operation by making several parameters visible at the same time. Titles are displayed in large bold type, and names are spelled in full wherever possible to minimize the frustration of trying to decipher a screen full of abbreviations. There are a number of flow diagrams and bar graphs that are displayed in graphic form for easy recognition. A set of "smart" function keys also make it easy to move around in the parameter-packed programming environment. For data entry there is a choice of increment and decrement buttons, a numeric keypad, and a data entry slider for fast absolute value changes.

Multi Timbre Mode and Built-in Drums

Up to 16 different voices can be assigned to 16 different MIDI channels. An external MIDI sequence recorder or music computer can be used to control various voices in this mode, achieving sophisticated music production capability with a minimum amount of equipment. 16 memory locations are provided for complete MULTI setups including voice-to-channel assignments, individual voice volume, note shift, tuning, panning, and effects. Individual voices can be assigned to 8 individual outputs as well as dual stereo outputs, which can be fed to a mixing console for further creative control. Percussion samples can be assigned to 61 different notes and handled as a single voice making an external drum machine unnecessary.

Individual & Dual Stereo Outputs

To allow individula handling of elements or voices, there are 8 individual outputs in addition to two pairs of stereo ouputs. Elements can be assigned to individual outputs as well as either or both groups.

External Data Card Storage

Voices and waveforms can be saved to and loaded from compact Yamaha MDC64 data cards. A single card holds up to 64 voices.

Complete MIDI Implementation

The TG77 offers a complete set of MIDI parameters for maximum compatibility and versatility. Receive and transmit channels are independently programmable, a program change assignment table maximizes voice selection versatility and a range of bulk dump functions make data transfers to bulk storage devices quick and easy.
