Main Features

Yamaha Education Suite

................................................ Pages 60-71

The PortaTone features the new Yamaha Education Suite — a set of learning tools that utilize the latest technology to make studying and practicing music more fun and fulfilling than ever before!

The Yamaha Education Suite includes:

Chord Guide functions in the Style mode

Smart and Dictionary — that make it exceptionally easy to learn chords and chord relationships. There’s also a powerful EZ Chord function that lets you easily record and play back chord progressions.

Smart lets you easily play harmonically “correct” chord progressions for whatever key you specify. It’s great for learning — and performing!

Dictionary is a built-in “chord encyclopedia” that teaches you how to play specific chords. You type in the chord name, and the PortaTone shows you which notes to play!

EZ Chord is a powerful and simple way to pro- gram and play chord progressions. Record all the chord changes you need for a song, then play back the chords one after another by simply playing a single key!

Portable Grand

The PortaTone also has a Portable Grand function for realistic piano performance. Pressing the PORTABLE GRAND button instantly calls up the stunningly authentic “Stereo Sampling Piano” voice and configures the entire PortaTone for optimum piano play. Special Pianist styles — with piano-only accompaniment — are also provided.

Other powerful features include:

Exceptionally realistic and dynamic sounds with 100 voices, utilizing digital recordings of actual instruments.

Dual voice and Split voice modes that let you layer two voices together or assign two voices to separate sections of the keyboard

Four high-quality effects — Reverb, Chorus, DSP, and Harmony — each with a variety of different types.

100 auto accompaniment styles, each with different Intro, Main A and B, and Ending sections. All styles (except for the Pianist styles) also have their own four Fill- in patterns. The PortaTone also gives you convenient control over accompaniment Styles — including Tempo and independent Accompaniment Volume.

Powerful song recording operations for recording and playing back complete compositions (three User songs are available). Up to six tracks can be recorded to a song, including a special chord track for style accompaniment.

One Touch Setting (OTS), for automatically calling up an appropriate voice for playing with the selected style. Plus, there are 16 User OTS memory spaces that let you save your custom panel settings for instant recall.

Touch response (with front panel on/off switch) for maximum expressive level control over the voices. This also works in conjunction with the Dynamic Filter, which dynamically adjusts the timbre or tone of a voice accord- ing to your playing strength — just a like a real musical instrument!

Convenient footswitch control over various functions — including sustain, start/stop, and more.

GM (General MIDI) compatibility and full GM voice set.

Large custom LCD (backlit) gives you easy, at-a-glance confirmation of all important settings, as well as chord and note indications.

Comprehensive MIDI functions that let you integrate the PortaTone into a MIDI music system, for sequence record- ing and other advanced applications.

Built-in, high-quality stereo amplifier/speaker system.
