Vintage Synth Explorer

It is not easy to find on the market today, but below $ 600 in general, by the strength of their design, sound, operation, function, full MIDI is one of the best options to buy among the vintage workstation, including for use in stage performances.
This has a lot of very good sounds, editable and usable today. So if you get lucky and find one, do not think twice, are sought. I use one of these for some time.

The MP3 demo & media that you.can be heard here, undermines the true quality of the instruments. Search in YouTube.

i have one of these for sale real cheap and it comes with padded case and manuals
a great synth but i just dont need it anymore

I bought the QS300 soon after it came out. It was a major promotion from the QY10 I used previously and it took a while before I mastered the machine. A video tutorial then available on VHS tape by request from Yamaha helped enormously. The sequencer was excellent and its phrase/pattern-based approach clearly influenced Yamaha's later workstations, such as the Motif series, and grooveboxes like the RM1x and RS7000. The preset sounds were numerous and pretty good for the time, although there was a clear bias towards the brighter, happy, populist end of the dance/rave market rather than darker, more sophisticated genres such as IDM or trip-hop. There was no scope for real-time tweaking of sounds, however. The user interface, while okay for programming the sequencer, was not helpful for changing stuff on the fly. Multiple menus had to be navigated and basic functions, such as transposing the keyboard up or down an octave, could not be done at the same as the sequencer was playing.

Great machine then and now. Great bang for the buck.

The Yamaha QS300 is a beautiful and a very well constructed synth. It can reproduce powerful deep and warm analog sounds.Great pads too!! It has a good sequencer and good effects processors.The keyboard is good but could be better, but is OK.The GM set it's not special and needs brightness,but this synth is not for use as sound module,so we can say the GM set is an "extra" to use with the built-in sequencer and the built-in patterns.I look to the QS300 as a great Synth, but it was a very good workstation in 1995
