Patrick's new baby... TAL- J-8X

[zvenx]

...
Patrick, give us that second layer in J-8X to make a JX10!

As I am sure he told you... others have requested that too
I guess his only limitation is that he doesn't have a physical JX-10, but I am sure you and others can guide him.

There are some other differences in sound between JX8P and JX10/MKS70, so that would have to be a different mode of operation, if emulation accuracy is to be preserved.

BTW, since nobody's brought it up, the CPU hit on this thing is close to zero. I could probably run 100 instances of this thing and not notice it.

[EvilDragon]

It's definitely not close to zero, you need to watch the realtime CPU usage (main audio thread). All 12 voices with a long release time crop up to about 15.5% RT CPU in Reaper over here on my good old 4.5 GHz i7-6700K.

Never owned any but when I had googled it.. the differences that were noted was
1)Chorus
2) More Polyphony
and of course 3) the two layered tones..

actually this one says the filters are a bit different..

what other differences are you aware of?

But we all know why it was implemented this way - it's more complex, but it makes the most flexible use of limited resources. Which was more or less all hardware until memory constraints got relaxed and much cheaper as we headed toward the 2000s...

Absolutely. That is why I alluded to the 'constraints' that synths made in the 80s had to content with.
We take 'memory' for granted nowadays, but I remember a Sound On Sound reviewer of the Akai S1000 making a joke why there is a shortage of memory chips in the world....and it was because they were all used up in the Akai S1000 to provide two whopping megabytes of storage!

[EvilDragon]

There are some other timbral differences, probably the filter surrounding circuitry changes its behavior a bit, many users say JX10 sounds "glassier" (hinting at possibly somewhat different crossmod behavior as well). At any rate if you compare JX8P schematics and a single voice board of a JX10/MKS70, differences will pop up.

The most obvious other difference (but this is already covered by J8-X) is that JX8P only has a single LFO for all voices, freerunning, whereas JX10/MKS70 have per voice LFOs that always retrigger.

It doesn't matter. At least to me. Just having two layers of the current J8X will give another set of glorious sounds. As an example, the way the JX10 / MKS-70 can do brilliant X-mod pluck + pads is irresistible, and the current J8X could do that with two panels with ease.

[EvilDragon]

Yeah, you don't have to tell me, I do have a Vecoven'd MKS-70 right here.

Well then I must either have a super computer or using the wrong patches. My first song was 19 JX8 tracks and barely moved the need. And yes, I did check the realtime CPU usage.

FWIW, my PC is brand new and cost me $3,000. I told the tech, I want this thing to blow the doors off of anything I run.

It does. Huge sample libraries hardly register and that was a recent track with an 80 piece orchestra.

Well, whatever. All I care about is I'm not having any problems. That's all that matters.

[EvilDragon]

Yeah I should check this with my 9950X at some point too, heheh.

Does anyone have the JX-10/MKS70 presets as a syx file? I've found one source - JX10BNK0-A.SYX (Roland JX-10 / MKS-70 Factory Presets) - but it only seems to have half the Tones (the first 50) in it, and is missing the second 50... I'll have a look around, but if anyone has them and can share, that'd be cool. I'm wanting to set up a dual-layer J-8X set of JX-10/MKS70 presets as best I can...

How would you do JX10 presets? Can the JX8 somehow run doubled for JX10 presets, or are you somehow halving the presets and running each half in a separate JX8 instance each? Sorry to sound dumb, but I missed that this was possible.

Yep indeed! I was playing with two or three layers of J8X last night and it was lovely! I've always felt that the Roland analogs tend to layer well simply because they're not trying to be super-fat monsters like some other analogs are (this is part of the Roland family character I've always liked) - and with the glassy topend, you can get a really nice-sounding blend sounding like a analog/digital hybrid.

[beely]

How would you do JX10 presets?

A layer of two J8X's, each doing one of the two Tones (which are essentially each JX8P patches).

I use Logic, so it's a simple Patch being a summing stack of two JX8 instances/channels.

[audiojunkie]

1 JX-10P bank consists of 50 Tones max. and 64 Patches. Each patch combines 2 Tones. Correct me if I'm wrong!

You are not wrong. But, the presets that use the Tones in the JX10/MKS70 in each layer, use both the RAM Tones (of which there are 50), and the ROM Tones (of which there are 50).

The presets syx file has the 50 RAM Tones. What we - the plugin owners - *don't* have is the 50 ROM Tones, and thus cannot recreate the JX10/MKS70 presets yet. So I'm asking whether someone has these 50 Tones - which by their name listings aren't the same as the JX8P patches - as sysex data, so we can also load those Tones into the plugin, and therefore recreate the factory dual-layer presets.

Hope that's clearer. Basically, I'm trying to turn the J-8X into a JX10/MKS70 using two instances - but I don't have all the preset Tones required.

Edit: Now I understand. The 50 ROM Tones are missing and harder to find.

Yes, exactly!

Ah, ok. I thought the capability was already built in and I had missed it
