Roland JV-1010 Problem

[DavidT]

Hi,
Newbie here. I'm not sure how many people still use the JV-1010 sound module, but I'm having problem with it, and I hope somebody can help.

A little background information: My JV is hooked up to my computer, which is hooked up to my MIDI keyboard. So basically, the set up is:

MIDI Keyboard -> Computer (Cakewalk) -> JV-1010 -> speakers

Ok, here's what happens--
When I start a session with Cakewalk, everything works fine. However, after a while, things start acting strangely. For example, if I allow a 1 measure count-in and start playing the keyboard on measure 2 of a song, the notes I play will appear at the end of measure 1. The longer I use the program, the worse it gets. After a few hours, a note that should appear on beat 1 of measure 2 will be appearing at the start of beat 4 of measure 1 (assuming we're in 4/4 time.) That's a whole beat BEFORE where it should be! Needless to say, this gets annoying very quickly!

Now, I'm sure you're thinking the problem must be with the software, but if I unplug the JV and attach any of my other modules, everything works just fine. As soon as I plug in the JV again, the problem resumes.

Also, if I use a Cakewalk's metronome feature through the JV, it stumbles over itself for the first few beats, often starting out much faster than the song's tempo, and then gradually settling into the proper tempo. Again, if I use my other modules, the metronome works without any trouble.

Any help would be greatly appreciated. Thanks!

Some more information will help us to help you. Does the JV sound slow? If you connect a controller directly to it, does it take awhile for the sound to come out. Also when you say the note comes in early when recording:

"For example, if I allow a 1 measure count-in and start playing the keyboard on measure 2 of a song, the notes I play will appear at the end of measure 1."

Does this problem, slow down the audio on the metronome.? Finally .... are you recording midi directly from your controller, or are you using MIDI thru on the JV?

Best,

Thanks for replying, Jerry.
If I just play notes directly from the keyboard, it sounds fine. I can sit at my keyboard and play songs through the JV with no problem at all.

The metronome is screwed up. When I start recording, the first few ticks are not in time. The best way I can describe it is to say that they seem to stumble over themselves, going too quickly for a few ticks (not at a steady speed, though), and then settling into the right tempo.

As for the recording set-up-- I play the notes on my keyboard, they get recorded into Cakewalk, and then Cakewalk plays them through the JV. So the set up is:

Play notes --> Recorded by computer --> outputted by computer into JV

I really think my JV may just be defective since I've never had this problem with any other module, but if you can think of anything that may be causing it, I'd be extremely grateful. Thanks again.

The only thing that I can think of, is that there is information in the front of the midi file that the JV is choking on. Which causes the hiccup in the metronome beat. I'm used to seeing this when there is a feedback loop from the synth/module back to the computer, but not when it's a one way stream.

Are you using any cakewalk instrument definitions for the JV? Are you selecting patch mode, or any patches with sysex strings? Does this problem happen in performance mode only, patch mode only or both?

Also, what problems arise (if any) when you play back a regular midi file back on your JV directly from the sequencer without involving the controller?

I'm using an .ini file that I downloaded from lilchips (or something like that... it's been so long, I no longer remember the exact name of the site.) I don't use any sysex commands at all because, well, I don't really understand them yet anyway. I just assign patches to channels from Cakewalk, using the instrument names that came in the .ini file.

Playing back files is never a problem at all. The timing only gets screwed up when I record (and even then, the notes are recorded correctly with the correct durations, they just all start too soon (which, of course, causes problems when I attempt to quantize things.)

So how I've been working around this is I've been recording a track, then cutting it, pasting it where it should actually start, and then quantizing it (if necessary.) But, of course, it's annoying to always have to cut and reposition everything.

I assumed maybe my MIDI port on the JV was defective, so I tried using the Serial connection, but the same problem still occurred.

Your idea about it choking on information is exactly what it feels like is happening, but I don't really see how that could be the case with my set-up. Hmmm... maybe I just got a lemon of a module.

[Tusker]

Are you talking about audio recording? If the problem only occurs in recording, isn't it a problem between the controller and the computer, since the controller is the one providing the midi data?

Have you tried starting on measure (for example) 5?

I think it's something to do with the ini file. If you try it without using the ini file, do you still have the problem? Not that I'm dissing David Green, but it may be some version incompatibility with the OS on your JV or something.

Cheers,

Jerry

Normally I'd agree that the problem must be between the controller and the computer, but since I've tried using different modules (without changing anything else in my set-up), and they all work fine, I think the problem has to be with the JV. It's definitely strange, though.

I've tried starting on pretty much every imaginable measure, and the problem is always there. The only way to get rid of it (temporarily), is to either exit from Cakewalk and restart, or turn the JV off and back on again. Then it's okay for a while. But, again, the problem returns and gets worse as time goes on.

I'll try your idea about not using the .ini file... that never occurred to me. Hopefully that will solve it. Thanks for all your help!

By the way, could you recommend a site that may offer a better .ini file, assuming the one I have is causing the problem?
