Yamaha ps 55

Pardon my typos. Please see my tech sheet entry. 1973 sounds right. This is a very powerful keyboard, designed to run on two Roland Cube amps.YOU MUST NOT Y THE TWO CHANNELS TOGETHER. It is true stereo and instruments are weighted according to onstage placement of symphonic orchestra. I left mine at someone else's house too long and can't find the Yamaha power supply. I used to run on six D cell batteries but now I can't get all six in, so there may be an old one stuck down inside, don't know yet. If it will run I will be very happy even though I have a newer keyboard. This thing kicks butt onstage and the sampling is largely very nice. As usual, some horn sounds are a bit lacking in quality, but Yamaha was a leader in sampling in that era. Hang on to your original power supply and don't Y the two channels together. Run them separately into your sound board channels or use two amps. You can adjust the dispersion with the knobs left and right. If you can get a new one with the power supply, it's a good bet for the money. Saving arrangements may not be it's forte but it works really well for live performance.

Impossible to know if the generator is its analog or digital ... the machine was released in 1983 along with the dx7, but not obviously uses fm ... It sounds like these are analog predecessors, but impossible to have confirmation internetes the research is conflicting about and not based on any official documents ...

UTILIZATION

The config is very simple.
there is no editing will be possible for sounds ...

OVERALL OPINION

I had his cousin PS30 few weeks when I was 6 years old ...
Good in terms of archi arranger is exceeded, the interest of such a machine, if it is found in only a mouthful of epain is to divert its initial use is to make sound groundwater Vintage or to laugh with the bar that sounds to be kitsche (kitsche but not narrow ...)
It may also be one or two lead sounds ... just about a few dollars in a garage it will, but it seems PS even less grainy than the PS30 (impression?)
Can serve machine string of poor and lets go laugh on the beach (if you can find a battery ..)
In a ampilant his band and his solo, you can do some interesting things too (use effects)
it has a strong enough output level so it is well worth more entries listed ranges for certain uses ... but it has a little breath (MT32 kind)
For 150 euros, of course he will have a better track real synth: juno 1 or poly 800, another planet ... but this little ps is not ridiculous ... for a price "flea market / garage sale" there is no much to risk ...
Just for the box ultra pace kitsche we can find a interest ...
