Yamaha SK15

"Steel front panel, (real wood sides!) [hmm...*], with 22 dedicated sliders. There are 7 for the organ: 5 of these act as drawbars...16', 8', 5 1/3', 4', and 2'. The other two in this section are for organ percussion and a highpass filter to extend the range of organ sounds made with the drawbars. Good Hammond B3 sims to be had here in this section. The Strings section has 2 sliders, sipmly to mix and match amounts of sawtooth wave in 16' and 8' flavours. The organ section's brilliance control i.e. the highpass filter can be used to trim off the high frequencies of the strings' sawtooth waveforms. The Polysynth section has indie sliders for: volume, wave footage (mix variable from 16' to 8'), EG depth and 4 slider for the ADSR. This section also has a slider for filter resonance amount. The other remaining sliders are used for LFO control... depth, delay, and rate.

As I mentioned, there are three sections in the Symphonic esnsemble: Organ, Strings and Polysynth. Each is 7 note polyphonic and all 3 can be used together with no loss of polyphony. And here's where you can make some really magical sounds, because you can make composite sounds using all three sections that really sound wonderful! It's a bit like having a subtractive synth with simple additive features. Layering in some high organ harmonics over a subtractive analog filter sweep (this section is simple but sounds like a beefed up CS01 with 7 note poly), adding in some silky strings and running it thru the BEAUTIFUL swirly, sparkly shiny ensemble effect give me shivers cuz it sounds amazing! And the BIG bonus: every parameter has real-time control so you can get really expressive. There's also a foot volume pedal input that makes this thing really responsive even though the keys are not veleocity sensitive. Ahhh... magic!

Ther were 4 different SK series keyboards built: SK15, SK20, SK30 and SK50D. The 15 is the baby brother."

  2. EL SK-15 tiene un filtro espectacular, combinando las señales en el modo Polysynth se puede obtener una onda cuadrada, su efecto de Chorus es magnìfico, aunque no tan bueno como en el CE-20 aùn asi tiene un aspecto "vintage" de primer nivel y la afinaciòn es super estable!
