Yamaha PS-30 Automatic Bass Chord keyboard Orgel. Zeldzaam eerste portasound model

Mooie Yamaha PS30. Geheel schoon, geen stofzak en dus.meteen te gebruiken. Alles werkt op de speaker na, de output werkt gewoon. Interne speakers is 4ohm 5 watt en makkelijk te vervangen indien nodig. Maar indien je dus geluid over set up, externe speaker doet is deze niet nodig. Toetsen allemaal schoongemaakt, stofvrij en werken allemaal goed.

Dit een een zeldzame eerste "Portasound"uit 1981 van Yamaha. Bekende Beach sound.

The PS30 was the first Yamaha single keyboard. Additionally to the normal (polyphonic) main voice, the PS-30 has a "solo" voice section that can layer the highest currently played note with an additional voice, that is produced by a more sophisticated monophonic sound generator. This solo voice employs a real analogue filter envelope and produces a wonderful analogue synthesizer timbre. Unfortunately this instrument seems to be very rare. An even rarer black version (seen on eBay) was released as Yamaha PS-30B.

• rhythm "8 bar variation" switch (inserts a fill-in every 8th bar)

• All main voice timbres seem to be made from a mixture of multiple analogue filtered squarewaves with a common digital envelope.
• analogue percussion {base, snare, hihat, low & high tabla(?)} sounds rather unspectacular, although possibly more realistic than many other analogue percussions. The hihat is likely mixed from 2 digital shift register feedback noise outputs at the CPU. The base is a dull popping noise.

This instrument sounds very much like an analogue 1970th home organ and seems to be based on similar analogue technology like the Yamaha PS-2.
