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".

To Bert de Vries: I had the same issue with my YS. Took it apart, and re-screwed all the screws. Found that earth/negative/minus (whatever you call it) screws on the PSU board were loose. Hope that helps.

I've got one on eBay for about 10 Euros, but it was dirty and totally demaged. So I repaired and cleaned the whole Synthesizer. Now it is a great deal of Basses, Bells and Percusion-Sounds for my equipment in my homestudio. I never would miss this great underrated synth. It's in my eyes a great deal for bright and heavy FM-Synthesis-Sounds.

Well, tastes are tastes, I for myself love the sonic possibilities FM gives me. It's a refreshing change from all that analog/virtual analog stuff.

Here's a little demo I made on and for the YS100, maybe some of you find it interesting or even inspiring:


Download-links for the mp3 of the track, as well as an archive with all patches can be found in the YT info text.
