Title: Help with No Buffers Available error
Post by WytchCrypt on May 10^th, 2014, 6:03pm

Hi all,

I just began running MIDI-OX on a Vista laptop through a MIDIMAN USB MIDISPORT 4x4. I'm connected up to a Korg Radias synth trying to do a full dump and restore. The dump part runs no problem but when I try to send the SysEx file back to the Radias, it gets about 10% done then gives me the following error:

SysEx: No Buffers Available. There is not enough memory available for this task. Quit one or more applications to increase available memory and try again.

I've quit every application except MIDI-OX and keep getting the same error. I've tried configuring the output buffer everywhere from 32 down to 2 but can't seem to get around the error.

Any ideas?

Thanks!
Dennis

Great news! I found the right setting and it now works. I went into configure buffers and went from 32 256 byte output buffers down to 2 64 byte buffers and everything worked no problem!

Hurray for MIDI-OX!

I was receiving the exact same error message. I changed the byte buffers and still got the same error.

Turns out, the problem was that I had Ableton open at the exact same time I was attempting to update. I closed Ableton and the update when fine. Do not update your synth with a DAW open.

Same problem & solution with Prodipe Midi USB 4i/4o + Merge 2i>4o midi interface unit as-well! ;D ;D ;D

As both Prodipe Midi USB 4i/4o + Merge 2i>4o and the MIDIMAN USB MIDISPORT 4x4 are Class-compliant devices, they rely on the Windows generic USB midi drivers.

There's not a hardware problem as some people stated, but just the *limitation* of generic midi USB driver. It can't handle larger chunks of sysex data FROM Windows 7. Hence people need to manually set 64/2 byte as an OUTPUT buffer from MidiOX.

The funny thing is that there's no problem when dumping sysex FROM hardware units, as I have tested settings for up to 1024/16 bytes buffers without any error.

Just a tip: After sysex dump form hardware, always make sure to check it's integrity for errors by opening 'View >> Sysex >> Display Window >> Check Data' in MidiOX. I've noticed a lot of errors IF not using the appropriate uploading buffer setting.

Cheers.

Just for clarification here, I believe the early Midisport interfaces were pre class compliant and so had their own drivers.
The later M-Audio Midiman MidiSport interfaces (including the 4x4) are class compliant interfaces, but you can install their own Windows multi-client driver (and I strongly hope you do) rather than the rubbish MS one.

I have 2x2 4x4 and 8x8 interfaces - all pre "Anniversary" models and they work very well.

All the best
Royce

Yes, that's correct, I've missed to point that out. Although the M-Audio missed to point that out on the product page, as it only said "Requirements: Compatibility Class-compliant".

Maybe the Prodipe will do the same thing and release their own dedicated driver for the Prodipe Midi USB 4i/4o box as-well as that little has definite potential.

Cheers.
