Yamaha PSS-790
5 octave synth keys not velocity-sensitive and small.
99 sounds, 49 styles, a drum kit, not General MIDI compatible.
4 effects, pitch bend wheel.
8-track sequencer.
Sounds of piano and percussion very well for this type of product of good ground. The speakers recreate a powerful and round.
MIDI ports (in / out / thru) and headphone jack.


Small buttons (non-standard size: about 2 / 3 in width and length, it just go to a child or for the home studio). I use it connected to my PC with Reason and Ableton, orders changes of instrument, pitch bend are interpreted by software. But I dream of key size.


450 euros in 1992 when it was released at the time her most was to have good sounds and MIDI ports (in / out / thru). The competitors are a lot more for less but with size keys. I recommend for an adult because of the size of the keys.

- 100 Sounds AWM (Advanced Wave Memory) good enough qualit.les pianos, violins and brass are quite ralistes if viewed in the context of the era (1989). The synth sounds are pure pathtiques.possibilit to vary the sound with vibrato and reverb pourrie.pas of rglage ADSR Other. or limit the possibilities immediately.

- Function "vector synthesis" probably inspired by the M1 korg.on chooses four sounds and mixes as they want using the joystick.rsultat trsdcevant! if at least there was a function "detune" a little while to grow a. .. and more important loss of polyphony: no way to play more than three notes together!

- 50 styles.l also for the era c'tait quite impressive even if ism keep costs gives especially want to laugh ... accompaniments blues / rock are the only not have suffered too much time passes and you can type well DLIR in the improv style dessus.chaque possde his own intro + 2 + ending variations, accessible from the 4 red buttons conveniently located just above the keyboard.

- Keys taille.LE small weak point! VLOC no, no feeling in touch, it's really crap! but now for a large button keypad dbourser needed more often for less features (eg PSR500)

- Drum kit with eight pads assignables.sympa.pour to the con with my friends is chouette.seul inconvnient: they are so sensitive that it is not uncommon to open a dclencher Thurs without expr ...

- 8 Squenceur pistes.excellent! sr limit is well good: no edition not - not if we plant it must erase all the track ... but it will be happy! The big plus is that you can use it to MIDI! I pilot my JD800 and my Amiga for years with him ...

- 2 HP amplified very good quality. High volume are a lot of blows but fit well!

- Mains (standard plug) and consumes a piles.attention! if you pter watts your brave alkaline will not take long ...


Everything is easily accessible, I was 13 when I had my first c'tait keyboard and I think I quickly ignores the manual ... everything is logical and well thought out.


In the era c'tait a small keyboard full of sounds trs cool enough for ralistes era. Ct pure synth sounds is the zero-point.

It should be honnte now can not get much of a machine-like ci.Peut be that certain sounds are usable with a good multi-effect in the ass but honestly try to use it as a sound source Relva me of masochism.

it may possibly serve as a little extra MIDI squenceur ...

In retrospect I think that I compltement plant by buying a. .. I wanted to sound good typs synth 80s and not at all what his n'tait vocation.et then touches is hell!

50 Rhythms
8 Tracks 8 Tracks squenceur
8 drum pads 50 assignable drum sounds from
2 paramtrables Effects (Vibrato, reverb) + (6 types of harmony: Trio, Duet, .....)
Picht bend wheel adjustable


The use is very simple, personally I love the PSS I almost tried all gamme.Pour it sounds just do nice things, especially using the sequencer and the track vector in fact not use vibrato a little, but not assigned to each of the mode vector of the reverb is on is not recent.
The sounds of drums sounds great practitioner.
Regarding the manual, it must be said that inside the small yaa subtilis nice for such use in punch out of squenceur.


PSS My first was in 1988 and a 480 795 790 etc, it was my first real clavier.J 'I then move a lot of other ISP, but I never found the ease of dealing with one another, this binding, as I do.
For info, the only thing a Difference pss 790 795 is a vibrato effect on one end and sustain each other.

For me it's a keyboard that is used to speed dial, and anywhere. with a noise that is balaise.en hp more with the pad assignable trs pratiques.Moi I pss serves as composer, I inject APRS software in its noon then I redispatch in other key with the final sounds.

Fred60's review (This content has been automatically translated from French)" Great for the time!"

Yamaha PSS-790
Functionality rather interesting in light of its era and its very affordable compared to other competing products.


Its use is fairly simple since there was still no menus / submenus / sub-menus such as keyboards, arrangers actuels.Les functions were therefore "direct access".


This was my first keyboard and I have fond memories!
His most: affordable price, a lot of features and good sampling of sounds, rhythms quality with interesting variations, transportable anywhere!, Good amplification, MIDI complete. Compared to a PSR 47, which was worth around 4500F at the time, it was a good alternative if one accepted the mini-keys
His least: the little touches that eventually penalized when learning to play on a keyboard with standard keys, and then maybe the keyboard nonresponsive.

Therefore excellent value for money in 1991.
