I have had my JX-8P for three months now, and I love it! In these three months I have made more music with it, than in three years with my D-50, and that says something about the JX. (I still love my D-50 though) It is so fast and easy to program, and I don't even have the PG-800. I just can't get a bad sound out of it. It is easily the best purchase I have ever done. The synth itself is as close to mint condition as you can get, even the manual is like new - not a fold or stain on it! JX-8P is a highly recommendable synthesizer! :mrgreen:

JX-10 is even more recommendable, since it is basically 2 JX8P's combined into one shell.
Has lots of shortcuts to make programming simpler also.

Sadly, the JX8P I tested in a store had some strange flaw, it would shutdown every 20 minutes (like clockwork) and you'd have to go through the 12 second "warmup" procedure again. The store guy said it was most likely the battery, but that's hardly it :P Loved the sounds I got out of it though, while it was on. Some of the factory sounds were so nice I just played them for a long time.

For those who didn't get my "da-da-daaaa-daaaa" reference.

I've got a JX-3P and a JX-8P and can confirm the 8P is an AWESOME synthesizer. It's so.. purposeful :)

It looks cool (well, different from the usual crowd), it sounds amazing (especially the lower octaves which can blow your ear drums), and it's very flexible. The sounds are more advanced than on my JX-3P in that the 2 Envolopes and extra options allow more esoteric pads (Kinda like an Analog D-50, when D-50 is in Structure 1 mode).

I also love the 4 extra play modes (unison/solo etc), good portamento and patch bank feature... of course my aftertouch needs fixing but even so it's a very exciting synth. I use editors on the PC to program it but will also often call up parameter 52/53 and sweep the filter on the synths own edit know for playing around. I'd say it's actually easier to program from the synth itself than the JX-3P is as the screen makes it a lot clearer what you are doing compared to the flashing patch lights on the JX-3P.

The 3P has more of an edge in certain sounds and the filter is the same as the Jupiter 8 so it probably wins on being the more 'analog' sounding of the 2 and the step sequencer is fun. I love them both, the 8P is however more flexible and more fun to program with more possibilites and having patch naming/ram cart and most importantly MIDI patch dump and MIDI Editing make it the better of the 2 for noodling around with. I prefer BOTH to the Juno 6 I had. The juno of course has those fast analog envelopes and lots of goodies but for my kind of music the JX's actually work out better.. sound 'almost' as good for many sounds and 'far better' for sounds not possible on the Junos with their one osc.

Another underated Roland synth.. at a great price.

I owned a JX8P between 1988 and 1992, complete with PG800. I must admit I was never mad about it and preferred my Juno-60 at the time, despite the 8P's two oscillators. Both the 3P and 8P sounded thin to my ears (I owned both). I did use the stab brass patch (or whatever it was called) and Soundtrack but it never did it for me. I promptly replaced it with a Korg M1. I did like the keyboard fell and it performed well as my main MIDI controller too.

I sold my JX-8P and bought the JX-10.

It is twice as good, believe me!

I love my JX-8p, too. It's my first analog, and I have to say it's like .. a person. It has a voice, a warm presence. It 'glows' like none of my digital synths can. Not to mention it's incredible size and Max Headroom styling.

I have a BCR2000 hooked up and programmed to control parameters realtime via sysex (which I don't believe the JX-10 can do). Transforms it from a sort of stoned manatee into something a little more formidable.

Oh yeah, I had a JX-8p (and later a JX-10) for a while and enjoyed the sound of them both.
Obviously the keyboard action was garbage, but I MIDI-ed them to other synths and all was well.

I think people are starting to wake up to the JX's awesomeness, check out how much this clean JX-8p that was on ebay a few weeks ago, I can't believe for how much it sold for!

Holy s**t that price is absurd, but I love it - I've bought a couple of 8p's for about 50 dollars american and I've been able to resell them for 200 and 250. I've got a 3p on the way that I bought on ebay for 53.
I think ill be keeping the 3p if that sequencer is any fun

The person who paid that much has to be a newb. No one in their right mind would pay that much for an 8P unless they're a newb or just have money to burn. I liked my 8P and now have a JX-10, but I wouldn't have paid more than $250 for one and it would have had to have been minty for that price. They've been going for that rate since I sold mine back in '01.

The MKS-70, JX8P, JX-10 and Alpha-Junos all use the same filter topology: A 2 Pole lowpass in series with a 2 Pole Bandpass. This is quite different than the JX3P, which is an honest to goodness 4 Pole lowpass, as you say, of the same IC manufacture generation of the Juno 60 and Jupiter 8. The non-resonant Highpass and DCO design is also different. It's missing that second envelope, though.

I owned a JX8P for a grand total of 4 months and sold it for a loss just to get rid of the thing. They were built to be bargain DX7 substitutes, and I think it shows. All of the JX's starting with the 8P sound either too stiff or too "clangy" to me, with the cutoff up and resonance down. High resonance sweeps have this interesting little midrange distortion in them, but that sort of got old too fast. The amp dynamics are lifeless, it's impossible to get a 'full' sound on it,(even worse than an Akai AX 80) as it really has no bright fuzziness at all, and Solo2 mode is a joke. Can you do brass or pads without the chorus? I'm betting not. Even the doubled 3 voice is too stiff, imo. Alot of people want it for pads, but you can get a JD-990 for a bit more and have a much better sounding instrument with alot more flexibility.

All I can think of when I hear one is Tangerine Dream's Underwater Sunlight. What a disappointment that synth was.

I'm being honest here, but maybe you can post this review somewhere that those ebayer's can see it so the price will go back down. :)

Ain't no bandpass on the JX's.

The key to their 80's sound is having both 2 DCOs and chorus! The filter is fine, but not very fat.

Come back and tell me that after you've read the JX/MKS-70 Service Notes. Trust me, Roland didn't make this common knowledge, you have to look at the schematic.

I've owned both an Jx-8P and a JX-10. The 10 could really get lush if you layered things right. When I go back and listen to tracks I made with the 10, I'm always floored by the thickness and richness of the pads.

The PG-800 really helped. I hated the interface on those instruments.

What's the use of the bandpass in this case if it appears to be unused?
They were built to be bargain DX7 substitutes
The membrane button design was a big hit, though, but it's a substitute in that aspect only.

No, but it's nice and gentle :).

You have a point with the chorus, but all Roland chorus synths suffer from that weakness.

It's not unused, it's hardwired in series, giving you a 24db/oct Lowpass slope, and 12db/oct Highpass slope. You just don't always notice it because the non-resonant Highpass stage that comes after both has a bass boost circuit. I'd love to point this out in a schematic or service notes, but I can't even find rev 5 MKS-80 schematics on the web, which also uses this same topology.
