256 voice polyphony?? not as far as i can tell!

[Rocness]

I think the JP-80 is such a new and breathtaking way of doing things ,
that it may take some time for us to really understand it .
Maybe Doc has found something maybe not .

It would be nice if someone from Roland could clear this up but I don't think they post on here .

I would say to Doc keep making music and see if you run into any problems and let us know .
As for me the JP-80 has help me make the music that I have always dreamed of and it helped me understand,
that workflow is just as important as production. The scary thing is , that I have just touched the surface .

Yeah, there's a lot of lag on some live sets..

Maybe it's something that could be fixed in an update.

I remember when the V-Synth GT came out, there was for example lag when moving the rotary knobs (as well as lag on display updates), but that went away when Roland released 2.0 for the GT. I guess the code hadn't been optimized before launch.

So maybe it's the same here: in a rush to meet dead lines and market expectations, they released 1.02, knowing that the OS could be adjusted in the future.

Glad I found this thread. I spent some time playing through the live sets at the store. Came across the Marcato string set (I think thats what it was called). I tried to do some 7-8 not stabs in succession and could clearly hear voice stealing- it was so dissapointing- as what I was playing made musical sense for the set I picked (and this was without sustain as they didn't have on plugged in). It turned me off of the JP a lot- as I was thinking it would be a great main controller to consolidate my rig to.

If you stack enough stuff, of course you will run out of polyphony.

Unless of course you are one of the people that flatly deny any sort of limitation that the Jupiter 80 has. Don't worry, they jump in all the time to defend their instrument - even in the Korg forums - maybe even more there. There's less of them than you might think.

Some of these people can afford anything and I await their next purchase.

I have a JP-80 on order.
7 to 8 note stabs that lead to voice stealing seems wrong.

I suggest you test it out for yourself "in person" at the dealer, before you pay for it...

[JavaJ]

Please do try it out first. I am open minded and a big Roland fan (until I got rid of my Sonic Cell) so this is coming from someone who does't want to post negative stuff. It was just wrong that a factory preset would perform like that. Now, maybe some owner can check that out and see if they can replicate it- maybe there is a firmware issue (has there been a firmware update). This was a store model so it likely was just taken out of the box and put on the stand (ok, I am sure it was- those guys don't do anything extra special and Long and McQuade).

I just read this thread.

Try this as well (I noticed it in my JP80 test, and it leade me to procrastinate the purchase):

choose the famous "solo trumpet" sound.

Play solo: nice. Articulated, legato... Nice.

Play chords on it: uhm... good, less than awesome. But a nice "big band" preset. Add some "quasi-analogue" horns, and I could definitely use it in a Motown cover.

Now...

Play a chord with the left hand and try soloing with the right hand: eeeccchhh!!!! Each staccato of the right hand will cut the chords off!

No frigging way a 5 trumpets section wouldsound like that.

I don't think it's a polyphony issue.

I think there's a bug in the ARTICULATION engine.

This could be true for the bug you noticed as well.

My two cents, based on my limited experience on the Jp80.

ozy..Your post is excellent and what you say makes WAY more sense to me than Roland lying about polyphony in its specs. Furthermore, my own experiences do not reflect a polyphony issue, on the contrary they support the largest polyphony I have ever experienced on a hardware synth.

But....the type of artifacts you are describing is actually fairly common in "scripted" sample management. I get these exact same artifacts using products like LASS and Hollywood Strings from time to time...often in certain patches, or in certain playing situations.....the scripting gets overloaded, or confused.....or sometimes its just a script programming bug.

I have yet to personally experience this with the JP80 (and I am away from my studio for the day so I cannot try your suggested "test").....but if I did experience this, I would be more inclined to think this was a scripting issue, than a polyphony issue. When you consider the real time nature of these products, and the vast number of samples, articulations, and parameters which the "script" and "system" must carry out in real time...and then you start to "test" that system to see where its breaking point is....that may be a self fulfilling prophecy of failure. What I mean is.....Having 256 notes of polyphony is not a guaranteed license to play 256 notes of a trombone in one patch in rapid staccato manner. It may be that Roland intends for us to use a trombone patch in a more typical musical way, along with drums, and synth pads, and other keyboard sounds, to layer up a remarkable soundscape....and have the headroom to do it. These are two very different considerations when seeking to TAP that polyphony.

All in all...I am very dubious about the contentions of those who point to a mis-rep of the polyphony spec....and much more suspect of these other considerations which may lead to certain artifacts in the sound output.

[emenelton]

The scripting makes sense. My Post Piano, The Old Lady, would crash when the sustain pedal was let up. It was one of the first scripted pianos for Kontakt. You could play it all day with the sustained pedal held down. After you took your foot off of the sustain pedal it would hang up. Apparently it had to trigger every hammer off from each note that had been played while the pedal was depressed.

[JavaJ]

That sounds great and all- but I was someone who sat down for the first time and simply auditioned each preset from the front bank buttons and discovered this through normal playing (without a sustain pedal to even complicate things more). I don't think I have played another synth that did this so I would have to assume that Roland rushed this out the door without fully testing. Maybe patch creators emailed in their programming- and they simply baked them into the rom without fully testing the sets out. I guess users will have to submitt requests to their regional Roland sites and see if they fix this issue as I doubt any Roland person is here much that would do anything.

What Reg item because I put Marc strings through the Not stealing test and no note stealing was going on, unlike a7?

[RayS]

Ozy, 1805 solo trumpet ,,, I just tried it and did notice what your talking about.. it happened on me but only if I "didnt" press the chord notes exactly at the same time...?? However if you replay the chord again it seems to get reset or something and their isnt a problem..weird. Also I noticed that if play a 3 note chord, holding just the bottom note and then adding the top two notes in succession, the cutout is definitely there. The screen graph shows all 3 note chord being played also..but really isnt?? What I think is happening is that if you dont press the 3 note chord exactly at the same time the cutout will happen. Erhu strings I noticed it also..but not all sounds. Makes me think its a sensitiviy setting or soemthing..or maybe a factory setting. Try it again and replay the chord after it cuts out and see what happens..

[Bruce Lychee]

I have to try this tonight. Are you sure it doesn't have to do with the mono, poly, tone, etc. setting?

I never really try playing chords with the solo instrument patches. It doesn't sound right to me. Also thinking about the bass articulations, I can see why it would end up causing problems because they are dependent on the way notes are played in relation to each other.

[madAhorn]

Exactly...why would you choose to play chords with a SOLO patch?

If the note stealing happened on other patches, fine, but I would not be concerned if a SOLO patch did this.
