The following are a two demos and some details captured for the post.
"800 instant, high resolution sampled instruments taken from Matrix-1000, greatest sound module of the classic Oberheim world.
Legendary synth manufacturer, Oberheim had a wonderful plan in the late eighties: they developed a relatively cheap synth module with all the analogue goodies they had at the time (yes, fine oscillators and filters), give them a MIDI control and tons of preset sounds covering every sound style their instruments ever produced.
The result was Matrix-1000, and it fulfilled all the dreams with some exceptions. Its sound was as huge as an Oberheim should have, and they let it fly with 800 preset sound programs (plus 200 rewritable memory slot). But the control was not so perfect, you cannot edit the unit itself at all, and starting an external editor was also a pain due to the very slow microprocessor Matrix-1000 had."
"145 ready-to-play, high resolution sampled instruments recorded directly from Roland’s last analog classic, JX-10 a.k.a. Super JX.
In the mid-eighties Roland produced their most perfect analog machine of all times, the JX10 synthesizer, also known as Super JX. Structurally it was equivalent of two JX-8P synthesizer packed together in a single box, with wider, 76 note keyboard – but its fans loved it way many more than any of the JX-8P user loved his own instrument.
Super JX used up 2 x 2 oscillators for every patch combination you call up from the front panel – a so-called upper and lower unit of two sound boards. This resulted so huge, fat sound which is hard to describe. And they used the company’s best oscillators, followed by an excellent high or low pass filter which wasn’t too far from the ones found in the outrunning Jupiter series.
The only Achilles point was the lame MIDI implementation – but some experienced users solved the numerous problems and released an EPROM hack which made the instrument really usable."
