Korg 900PS Preset Synthesizer

Korg 900PS Image

This is the rare Korg 900PS analog Preset Synthesizer. There seems to be some confusion about the naming (sometimes called PS900), especially since the face plate says "Synthesizer Korg Preset." The 900PS is quite a basic but very interesting monosynth. The 900PS definitely 'borrowed' some ideas from the Pro-Soloist. Instant selection of 29 different tone colors. From the sweet sound of a violin to the chugging of a steam locomotive. Sensitive soft-touch switches and plentiful controls provide a wide variety of effects including vibrato, repeat, even the harmonics you need for a Hammond organ tone.

The 900PS has 29 presets: Timpani, Electric Bass, Synthe Bass, Piano, Harpsichord, Shamisen, Banjo, Mandolin, Xylophone, Tuba, Bassoon, Horn, Cello, Trombone, Saxophone, Voice, Clarinet, Accordion, Trumpet, Funky Trumpet, Synthe Trumpet, Oboe, Violin, Recorder, White Noise, Scale Noise, Harmonics I, Harmonics II, Harmonics III.

this synths sound quality will blow any modern digital synth out of the water if what you are looking for are fat anologe tones...... this unit basicly has preset mono anologe tones that would take ages to create on somthing like a korg mono poly, great design for its day and a hell of a weight. as other coments have said when you put it thru effects, whether it be rack units or pedals it put another slant on the whole sound produced, my prefered setup is using a reverd pedal a delay pedal and a wahwah... some sound.............................

I happen to own this one.. actually it's my first ever synth ( i've had dozens since) and unlike almost all of my other synths i still have it and would NEVER sell it.. although by modern day standards it's very limited, it has a very nice tone and the touch bar makes it unique, and gives you wide range of expression posibilties that i never found on any other synth since! sadly it's monophonic, but once sampled, the waveforms blend into chords beautifully! It will probably be very cheap when you find it in a little basement music shop... when you get the chance to buy a working specimen.. don't hesitate, get it while you can! it's a strange one but once you get the hang of it it's great!

HA HA I sound like a real nutter, but i just happen love this little darling!

Seems quite limited, but actually quite useable for many purposes. I think that the touch bar is a nice feature.

This IS a very basic monosynth but played through effects, and through a micrikorgs envelopes and filters it sounds cool!
