Korg Radias MIDI Bugs... Something Wierd Is Happening...

[MIDI_Thru_Kid]

Hello! I'm just doing some basic sequencing with Cubase LE4 (FIRST problem, right? hahahahahaha *slaps knee*), with my RADIAS, and at first, everything was great! I could put each timbre on a different MIDI channel, so I could basically have 4 synthesizers at once! Sweet! After a while though (kinda wierd there, right?), things started acting funny. I would be playing this string patch, and all of a sudden, the cutoff envelope would close up completely. No sound. But THEN, it glitches "back to normal,", but it will adjust the volume of that timbre (JUST the strings, nothing else), ALL BY ITSELF, then everything goes to hell, LFO's start adjusting and practically ASSIGNING themselves to parameters, Unison mode turns on, and parameters start getting adjusted there....

I noticed in the piano roll, I was somehow recording volume shifts along with the string patch at some point. I deleted these shifts, and all was well. I THINK I recall adjusting the volumes of the String Patch WHILE THE SEQUENCER IN CUBASE WAS RECORDING, (on accident), therefore that got recorded.

But that doesn't explain the other CRAZY stuff going on! This sound is changing to something UGLY while I'm playing the sequence in Cubase! I'm not even touching the keys!

You think MIDI CC#'s just got all jumbled up at some point, got recorded into the sequencer, and THAT'S why everything is all messed up? Maybe my OS isn't 2.0 (or IS...?), and needs updating? Perhaps it's just overheating? Maybe it's Cubase LE4, I mean it is the "Limited Edition" of an older version of Cubase (known for not being so great in the first place by many), and there IS a device reset function, maybe that would help?? It's an intermittent thing that happens with JUST THIS ONE SONG/SEQUENCE, and MOSTLY with the string patch (sometimes with others if I spend enough time on them). This is kind of scaring me, because I don't want to deal with repairs, and plus don't you think it's kind of scary that your synth is ADJUSTING PARAMETERS ALL BY ITSELF?!?!

I'm pretty sure I've seem/read horror stories like this online, I just can't remember if it was real or if I just dreamed it....

So can you guys help me out? Is my RADIAS the devil? Better question, is this a common problem, like OS re-boot, or something? I'm reluctant to do the OS boot becuase of all the horror stories out there about the RADIAS breaking down......

HELP.....

I would say it is not a problem with the Radias at all.

Strange things will happen with MIDI when you don't exactly know what you're doing.

Keep in mind that if you're working with MIDI tracks in cubase, it will send level, pan, and other controls when the track starts and such - from the MIDI track's mixer settings.

Have you tried changing your Radias to work on a different channel?

Also, do you have the knobs set to 'catch' mode? if there is some jitter or even physical vibrations from speakers or whatever causing your knobs to randomly send off values (which will match their position. quite easy to spot once you know what to look for), 'catch' will solve that as the parameters aren't adjusted unless the knob actually passes the stored parameter value.

It would only be a problem with the Radias if you still get this problem outside of Cubase, running on its own.


A few things:
What connections do you have to/from the Radias?
What other software and hardware are you using?

I appreciate your advice.

What I have is INTERFACE (Cubase LE4) OUT to Radais IN, Radias OUT to INTERFACE IN (for sequencing purposes, so I have a keyboard, etc), Radais THRU to Yamaha RX5 IN, RX5 THRU to MIDI Splitter Box (Homemade), which splits the THRUS to the INS of my TR-505 and TR-626 (No thrus there).

So, it's a fairly lengthy, but well-thought out setup, I think. I think I'll try that know catch mode, and set the GLOBAL MODE settings to JUST pitchbend, modulation, and no other "complicated" MIDI CC's, just the basic stuff for now.

But seriously this isn't a known problem?

Also I'm no novice at MIDI, I know you didn't mean that, I just want to get that across. And I'm sure as hell no expert, either, as this thread shows.

The problem is that many midi issues can be traced back to user error, not hardware problems, so if anyone is going to guess where to start looking for the problem in your case, the odds favor something other than the hardware. The first indication of a user error is that you are using hardware midi on an Audio I/O card instead of the USB midi. USB midi is preferable because it eliminates the need for a midi interface in the middle, which could be a factor that participates in the problem. The direct USB midi connection also frees up those midi ports on the interface so that you could use them for something else, like eliminating one of the midi thru connections or the splitter.

Do you know everything in the midi data that you're sending to the Radias? Have you inspected every single command to ensure that you're not sending it something that is not expected, like a sysex that means something very different on the Radias than where it came from? Where did you get the midi data? Chances are high that you're sending it something that is causing the unexpected behavior you are experiencing, even though the Radias is probably behaving exactly as it should when receiving the midi being sent. At least, that's the most likely scenario until you prove otherwise (not to us, but to yourself).
