JV-1080


Recommended Posts

Posted

The JV-1080... This synth seems to recive midi data pretty bad in a full sequense mode. There seems to be no way to program groove with the drums and then play somheting (instrument) over it. The timing are so fu...*"###***""## bad...(sorry) but im so frustated!! Am I completly mad or are there anybody out there hwo fell the same? Are there any solutions? Drums on ch 1. Turn off somethimg hwo block the processor,, etc,, Please give me a hint what i can do...

 

Best regards (and sorry for bad English)

Thanks for your reply!!!...Hmm... Maby your sequenser is more rock solid than mine, and your 1080s are therfore working better.... I have test the 1080 on many sequensers (sadly only soft..) on both PCs and Mac's. There seems to be some improvments on a mac with Logic and a proper interface. But its still far from good. Other synths like my old Prophet10 and Juno106 are much better in compare to the 1080 for the midi timing. And there is no wrong with my 1080 unit. The same fenomen with an other 1080 unit in the studio... And i feel the jv-2080 are even worse...

A lot of synths will choke if you throw to much midi info at the same time. Have you tried shifting around some stuff, so that you don't have 128 (or whatever the polyphony is; just exaggerating here) note on's at the same time?

I've never had a problem with mine. Channel 10 is the default drum channel for the JV-1080 in Performance mode.

 

Have you tried filtering your MIDI data? You may be sending lots of unnecessary data to your JV (Channel Pressure messages are a typical channel clogger). Your sequencer and master keyboard will allow you to filter out this data if you can find the right controls.

 

What kind of MIDI interface are you using? Sequencer? Computer (year and model)?

Ive been using my 1080 for a few years now without any glitches at all....

Make sure it is in PERFORMANCE mode and each track has a different midi ch assigned to it. Drums are on 10. Read the manual if you are not sure how to do this!

Try adjusting the Voice reserves if it is stealing notes... but the timing really shouldnt be a problem unless you have just too much data going to it!

 

Of course.. it may just be faulty...!

Well, true enough. There may well be an *initial* bottleneck on playback as described in the link provided. I got around this problem by starting my MIDI sequences in DP at measure "0", which contains all of the initial patch and midi controller information. Then the "musical" portion of the sequence starts at Measure 1. That gives the JV-1080 a measure to get all of the initial information for the sequence, and provides completely smooth playback from there on out.

 

If you haven't already, try this method and see if it solves the problem you're experiencing.

Just had another thought...

 

The reason that the "bottleneck" can occur in the first measure is that the initial patch and midi controller settings for a variety of tracks are all sent at the same time.

 

This same principle can apply to heavily quantized sequences -- any chance that could be the culprit?

The link I provided only provided other links, and yes, initial bottlenecks were discussed in a couple of them. That said, a more thorough exploration of the links provided will show that MIDI timing slop on a JV-1080 is experienced by many owners in many different situations...not all of them limited to initial bottlenecks.

 

Then again, MIDI timing slop was fairly common in modules from that time period it seems...The E-mu Orbit/Planet Phatt/Carnaval arent going to win any awards for MIDI timing either.

Go tell someone you love that you love them.

One posibility might be if you have the MIDI THRU retransmitting all of that MIDI info back to your computer, and then the computer re-retransmitting it all back to the JV-1080. Sort of a MIDI echo. Try disabling the computer's MIDI THRU, or just yank the MIDI cable out, and see if that solves your problem.

It's doubtful that the problem is something inherent in the unit itself -unless it's a faulty unit. 9 times out of 10, it's something you've set up wrong that causes the problem.

Thanks aeon for your info and links!!!. You showed that im not alone... Thanks also to all other replys. I have test the whole bunch off tip... But the problem remain.

 

An simple test:

 

1. Play some fast chords with an "four tone" patch in perfomance mode, (NO, you dont need an loong realize to this sound) Add some basic drums and bas. (No, not to much, only basic modern comp), Send those sounds to an separate output.

 

2. Then mute those sounds on your mixer (not in the sequenser) and try to play an piano part (or whatever,) with two hands in realtime over the sequensed material (No, you cant hear the backing traks).

 

Soon you will feel that there something wrong. You lose the musical control... Even if you are onley using ca 25-35 voices (half of the JV:s 64)

And if you want to be even more dissapointed. Quantize the whole thing. (bring upp the backing track again) I know that you should avoid to play on the same midi tick. But there are many other synths and modules around hwo is capable to this (very basic arr)in an acceptable way. There is limitations with MIDI... But the JV is even slower. In this case you dont hear the midi limitations. (offcorse there are some off you who can..) You just hear an JV-1080 who cant play in time...

Yes Aeon!!! this seems to be the sadly case...

 

If there are anybody who feel that the JV-1080 (or any other mid 90:synth, because its intresting to know, even if they are diffrent units...) seems to be faster when: (for example..) changing expansion card slot, (or drop a card)

Put the drums on midi ch:1, Turn off midi channels who not in use, turn of the humble effects, etc, etc......Please post!!!

tofrance,

 

Are you using voice reserve? Make sure that your drum channel has enough voices for the drum part and the bass channel has enough voices for the notes that it has to play. Set the number of voices using the voice reserve parameter in Performance mode. Then play on a third channel (no voice reserve needed here). The part that you're playing by had may be stealing voices from the backing sections. There are 64 voices available, but they get used up quickly with four-layer patches.

Thanks Dan, for you replys!! I have turn of all controller data as you suggested in an earlier reply. I have count the voices im using and they are not more than ca 32 (with release voices). I will start experimenting with the "voice reserve" to see if this makes upp for better midi timing. Maby this is the key...

 

Best regards:

 

Jesper
