Yamaha YS200

The YS200 is a 4-operator digital FM synthesizer in a rather funky looking keyboard design released in 1988. It featured an 8-track on-board sequencer with many advanced edit functions and up to 8 song capacity. It has a 61-note velocity/aftertouch sensitive keyboard, can hold up to 300 patches, two LFO's, vibrato, and more. It tends to produce very deep dance/techno basses, eighties digital synth sounds, and new age sounds.It uses the same synthesis as the TX81Z, which means it has 8 waveforms to choose from rather than just sinewaves, which gives it a wide range of possible sounds.

The complexity of FM synthesis is somewhat relieved by the "Easy Edit" controls for basic editing operations, but this can also be limiting since not all parameters are accessible. Full editing of the patches requires a MIDI based patch editor, such as YSEditor, which is available for free but only for the Atari ST. Fortunately, it works on Atari ST emulators for the PC. It's worth the trouble because it allows you to load up your YS with original patches from the TX81Z and some of Yamaha's other classic 4-operator DX synths, making the YS a good way to get your hands on classic patches from several keyboards all in one box.

Yamaha EOS B200

The Yamaha B200 is essentially a YS200 with speakers and a more subdued appearance. The B200 uses rather powerful 2 x 20W speakers and also has a stereo line-in (for amplification only). The pitch and mod wheels on this version form two halves of a sphere, which looks modern but ends up being a bit awkward. In Japan, the B200 was called the "EOS B200".

Finally got my YS200 working again! :-) A 7912 Voltage regulator (12Volts negative) on the powersupplyboard was malfunctioning. I bought a new one for 1,25 Euro, desoldered the old one, put the new one in and the synth is sounding fine again! Also the aftertouch is working fine again. The testprocedure showed that the aftertouch did not work, but now the regulator has been replaced it works fine!

@Tom,
Sorry for my late reply, but i will look at it to see if that is the same problem with my YS200.
Thanks for your tip!

Hey Dirk,

yeah, the battery of your YS is dead. It's a CR2032 button cell, instructions on how to replace it can be found all over the 'net.

I picked up this synth recently but every time I turn it on, it starts with the sound transposed up +64 octaves retuned too high as well. I need to hold down the note transposition for a while to get it back to 0. Also, nothing stays in memory after I turn it off. Saved patches have names in a strange gibberish font and sound like weirdness. Anyone know what the problem is? Is there a battery that's died or something?
