APC Mini Error: MIDI IN Buffer overflow (MIDI messages lost)

Hi all,

Ive only just started using BOME MIDI translator pro, so I’m in the process of learning all the tools at my disposal. However, I’ve hit a wall with this error that is constantly reoccurring.

I’m using an AKAI APC mini to control GrandMa2 onPc software. I’ve purchased a BOME box with the intention to use this  controller with a desk without the need for a laptop.

Ive managed to set up CC translators for the faders and LED Feedback for my buttons.

The issue is when I move the faders too quickly, I’m causing the APC mini to stop responding.

Ive seen a similar post on this forum but the answer to the question wasn’t clear to me as their example was on a much larger project file and my knowledge of the program is still fairly sparse.

Any help/advice would be appreciated!

Hi,

Yes, I’ve found that the APC MINI crashes when sending data back to it too fast. This is most common with fader data so I would suggest you filter out feedback from your APC MINI faders going back to your APC MINI. This is the most common culprit as moving the faders can send a bunch (128) MIDI messages in jus one swipe of a fader. There should be no reason your APC MINI needs feedback for faders anyway since the faders are non-motorized, the data is really not used.

If it still crashes with fader feedback disabled, there are also ways to “throttle” the feedback of buttons as well. Just post your project file if needed after disabling fader feedback and I will be happy to have a look.

Hi Steve

Thank you for your reply.
How would I stop fader feedback to the APC Mini?
I can post my project if that’s easier for you to have look.

Thank you,

Yes, please either post your project as an attachment in an answer, or send it to me via email. I will then make adjustments and post it back here as an answer.

Hi Steve,

Please see attached file,

This is my first attempt, so any advice you can give me for improvements is welcomed. I used your toggle example file as a base for most my LED feedback translators.

Thank you,

Hi, This will probably fix it. Basically I went to the preset called “APC MINI FADER” and set it up so that it only looks for input from APC MINI and only sends output to Bome MIDI Translator Virtual One port.  See the attached screen shot.

Keep in mind that unless you override the default project ports at either the preset or translator level. The translators will recognize anything from the all of the default input ports and also send to all of the default output ports.  It is usually good practice to set all of the ports you are using at the project level. Then use presets to override the defaults to only the ports you want.  Then for exceptions, override these presets at the translator level.

 

How did this work out for you?

This is working great!

Thank you for the explanation about routing, It makes sense now.

Cheers,

Thanks. Glad to have been of help!

Hi Steve,

I’ve now uploaded my project onto my Bome box.

The Bome box is now standalone, it has an APC mini connected for input and the lighting console is connected via midi as my output.

The midi being sent from the box seems intermittent when i move my fader normally. If i move it very slowly the midi information being sent is correct but becomes erratic or simply stops when moved any faster.

Is this a log window that I can use to monitor the Bome boxes processes.

The console I am using has system window where i can monitor incoming midi. This is implying that it is not recieiving midi. Therefore, the Bome box isn’t sending out midi reliably.

I’ve updated my Bome box to the lastest firmware V1.3.2.

Kind regards

James

Hi,
In order to see what is going on I would need your latest project file as well as some screen shots of your BomeBox interface. Specifically the page on the running project file, then connected, ports and the MIDI routing pages.

My guess is that somehow one of the aliases/routes is set up incorrectly due to an error somewhere in the project file.

Hi Steve

Thank you for your recommendation following our email. This hasn’t improved the problem.

It’s still experiencing the same issue.

Could it be that the Bome box cant handle the amount of CC changes?

Is there a log window for the bome box i can view like on the software?

Cheers

Hi,
No something else must be going on. Let me load up the project on my BomeBox and test it. There is no MIDI-IN MIDI-OUT logging function on the BomeBox, but you can redirect input and output via web interface using Bome MIDI Translator Pro to see what is going on. Instead of Directing your GMA2 output to the MIDI DIN Port and GMA2 Input from the MIDI DIN Port, set the Alias to go to you PC Network port and then monitor what is happening there in an instance of MT Pro running on your PC.

Hi,

I loaded up the project file I sent you into my BomeBox and it appears to work fine.

I assigned aliases as shown in the screenshot below and then monitored the output from the APC Mini with another instance of MT Pro running on my PC (instead of GMA2).

I also attached the project file.
