Hello all~

 

I using 'sensor in a box' on behalf of midi controller.

 

(accent sensor in a box -> Pysical computing with Micro process. similar 'Arduino' http://www.arduino.cc/ )

 

 

This device connect at WO5, occur ERROR message.

Hello,

 

Watchout V.5.1

Midi Controller: KorgNaNO2

 

as soon as I raise a fader too fast,or more faders simultaneously,I get a message: "Error:Midi I/O buffer overflow"

Do you know how to solve this problem?

 

Thanks

 

Regards

 

JP

with the same controller i also cannot use the first slider: an I/O error appear.

from the slider number 2 to the last one everything works fine.

I am getting the same error with WO4.3 and Korg Nano Kontrol.

 

There is no information about this error on the support documentation.

 

Does anyone know what is this about and how to solve it?

 

Thanks

I'm having the buffer overrun problems with this Korg Nano 2 controller and Watchout, though I've seen it work perfectly with other software. If I move one fader at a time I don't have any problems, but if I move two faders quickly to full travel in either direction the 'status bar' in the input window stops moving at a random number (OTHER than 1 or 0) in the middle of the travel and I get the buffer overrun error.

 

The problem Luca mentioned is based on the fact that the controller identifies the first fader as control '0' and Watchout will only recognize Midi channels starting with 1. This seems like a simple thing that could be corrected in the next version of watchout?

 

The buffer overrun thing may be specific to our Korg controllers... though the fact that other software (I've got it working in Resolume Avenue at the moment) responds perfectly makes it sound like there's something up with the midi implementation in Watchout?

 

Is there more info I can provide that will make tracking these issues down easier?

I think that my be a difference in the implementation of the MIDI standard.

If you read the published protocol, there is no MIDI Channel 0, they start at 1.

The published protocol states that MIDI channel 1 has a hex value of 0,

so Korg may be interpreting things a bit differently.

There are sixteen MIDI channels available.

Some vendors choose to incorrectly label them 0-15

while others choose to correctly label them 1-16.

So if your Korg offers 0-15,

then likely Dataton MIDI channel 1 = Korg MIDI channel 0, etc.

The article is irrelevant to the above problems.

 

I had a buffer overflow error message once when i was testing out a borrowed Behringer BCF 2000 with Watchout 5.x. I can't recall exactly but I think the error message is due either to a connection error between Watchout and the MIDI controller or a wrong setting on the Controller such that it is sending something that overloads the MIDI inputs on the WO computer. I solved it then but can't remember what I did exactly.

 

Check all your inputs and output connections between MIDI Controller and Watchout PC (should be simple basic stuff), and read the manual of the MIDI Controller.

In what context are you encountering this error?

We would see errors like that with MIDI in older versions, what version are you using?

v 5.5.1

No MIDI (Error only said "Buffer Overflow" - no mention of anything else.

No inputs or outputs. No external control.

Only two outs from a single machine.

Got a couple Aux timelines, but they aren't doing much. Almost all the show is in the Main Timeline.

A couple comps, but I can't isolate it to that.

 

Message would pop up while I'm sitting paused in the timeline...I don't recall it happening while I was playing anything. Also popped up once after I refreshed changed media.

 

Like I said, hasn't affected anything. Just curious what it means so I can avoid...that box popping up always makes me a touch nervous.

I received this message recently (5.5.1). But it was because i was switching between different MIDI monitoring tools / USB midi vs standard MIDI etc, when using a combination of controllers together.

 

I haven't had the same problem using standard MIDI devices via a PCI-E Midi port. It seems to be much more stable than connecting via USB (it also means watchout can see more than one controller).
