Yamaha PSR-7000 Portatone

Overview and synthesis

KEYBOARD PSR-7000 has a five-octave keyboard sensitive to velocity and aftertouch, two knobs (modulation and pitch bend), a 3.5 "floppy drive integrated on the front panel and a LCD screen of 320 x 24, at the bottom of which there are eight display knobs which, associated with the eight buttons on the display (four on each side) allow the functions present on the screen to be executed precisely.
On the left, at the bottom of the screen, there are 8multi pads whose function varies according to use. In Percussion mode, these are used to play eight different drum instruments from those in memory and those from the personal kit.

CONNECTIONS headphone jack and a microphone type input jack, both in 6.35 mm format. The microphone sound is processed by the PSR-7000 and amplified by it, the volume control being effected by a rotary button, just next to that of the general volume. On the rear side are the inseparable MIDI sockets (In, Out, Thru), a stereo output (6.35mm jack) as well as a stereo input (also 6.35mm) allowing mixing of an external source with the PSR-7000 sound. Three sockets complete the connection with two switch pedals (optional) and a volume control pedal (optional).

Arranger and Effects

ACCOMPANIMENT Various accompaniment modes, for example, choose the Single Finger option which allows you to produce major, seventh, minor or seventh minor chords from a minimum number of keys or the Full Keyboard option which creates an automatic accompaniment according to your play on the entire keyboard. Obviously, simpler options like Fingered Chord 1 or 2 allow automatic accompaniment from a chord plated with several fingers on the left side of the keyboard.

ARRANGER Yamaha Arranger allows 120 styles of pre-programmed accompaniment and 32 styles of user-programmable accompaniment. These 120 styles are organized into 11 groups e.g as rock, ballad, disco, Latin, jazz ... and are directly accessible by the eleven keys in the Accompaniment menu of the PSR-7000. Each press of one of these keys will display a screen in which you can choose (either by the scroll wheels or by pressing one of the keys on the display) one of the accompaniment styles. Once the choice has been made, the Yamaha arranger will automatically determine each part intended for accompaniment. These parts can be summarized as follows: rhythm 1, rhythm 2, bass, chord 1, chord 2, pad, phrase 1, phrase 2. During the accompaniment, two variations (fill-in) are available allowing to enhance your game or to create a transition between the two main variations (Main A and B) proposed. To summarize, each of the 120 styles has two introductions, two main variations, two "breaks" and two end variations.

EFFECTS features 16 reverb effects, a chorus +50 digital effects fully programmable e.g reverb, you can determine the type, time, distribution, setting of the delay before the sound starts, the cutoff frequency of the high-pass and low-pass filters, and the depth of the effect. The other effects are programmed identically, following the small tables shown on the screen containing the values of the parameters that need only be validated using the display keys. Also a five-band digital equalizer directly accessible by pressing one of the buttons on the control panel of the device.

Sound structure and Data Storage

SOUND polyphony of 64 notes with M technology (rompler) with many presets: 246 orchestral sounds, 123 solo sounds and 18 organ flute tracks. Each of these sounds is fully adjustable with eight display knobs that act as harmonic bars, as well as rotary speaker settings where attack, amplitude and volume can be instantly adjusted.
A sound consists of one or two waveforms (PCM) out of 656 wave - more can be loaded from a floppy disk or a hard disk. The available editing parameters are the pitch, volume, pan, pitch bend, modulation and aftertouch sensitivity controls, to which are added the filter and amplitude settings. envelope (variation speed and output level) as well as the effect parameters (reverb, chorus, DSP) and LFO.

STORAGE The Yamaha Portatone uses HD and DD disks in 3.5 "format which it formats to the MS-DOS standard. So you can easily import your sequences if you work on PC, Atari and Macintosh. Hard disk is optional.
