Midi-OX hosted tutorial, settings dont work for me

2015-08-03 by itssbrotha@...

Hello guys and girls,

I was reading the "Midi-OX settings for VZ-1" pdf yesterday (from the group's hosted files) to send a sysex to the VZ-1 and when I do that I get BUFFER FULL constantly flashing on my VZ-1.

The proposed settings are 256 buffers of size 56000 bytes.

If I try a lower buffer size (I tried 128,256,512 iirc) I get "Load Error - Check System." on the VZ

Some fine lad sent me a link to another app (SendSX I think ?) and that worked right out of the box with

no tweaking of the settings. But I would like to know what settings would work in Midi-OX as I already use that app for other keyboards.

Good day to all !

I know I posted a little problem-solution guide to the sysex-related error messages. Let me see if I can find it. (It was ages ago.)

The first error message does indeed sound like the data was being sent too fast; so, slowing it down or inserting pauses between groups of data should help solve that one.

As for the second error message, maybe this will help, though you seem to have third type of error message (Load Error: Check Message), so I am not sure. I couldn't find the "previous message about channel and data type matching." Maybe I had the error listed there. Casio CZ/ VZ/ FZ - Pro Series

*Here are the error messages I have been getting when sending VZ
sysex data to the VZ-8m. (See my previous message about channel and
data type matching.)
---------------------------------------------------------------
Message: --TRANS ERROR--- | CHECK SYSTEM!
Problem: Data channel <> VZ receive channel
Solution: Change VZ channel to match sysex file data.

Message: --MIDI ERROR--- | RECEIVE ERROR
Problem: Data type transmitted <> Data type expected
Solution: Select proper data type when loading data type into VZ.

With regard to the first error -I do not know specifically about the VZ - but Yamaha use 'channel' sometimes within the SYSx message to determine one among many of the same type of module within a dumping scheme.
That is if their were two FB01's running on the same MIDI channel for the purposes of left and right stereo sound production (or alternate key assignment) then they can have different SYSx numbers when dumping.
The dump channel number then needs to match in order for the desired module to be the one that gets the dump,since there is no 'midi channel' number on the dump command itself.
It is therefore possible to be sending a dump to a module and it not respond because it is not on the correct 'dump channel' - I do not know if it applies to VZ - but it seemed like this might result in the message given.
This means checking whether the VZ has a 'dump channel' within the SYSx message and whether it is the same as the transmitted code.

The second error sounds like the 'speed/pause' one since nominally sysx data is sent as 'nybbles' (values below 16).If for any reason data speed causes some mismatching of  bits and data ends up >16 then there'd be an obvious data error.

Here's a thought in case you haven't solved the problem(s) yet. Instead of adjusting the size and number of the buffers, first try putting a delay after the F7. It seems my default is 60 ms. You could then try using the auto-adjust buffer delays.

Let us know your progress.

PS: I don't have a VZ-8m connected to my PC at the moment, but if you are still having problems, I can try some troubleshooting if you upload the sysex file you are trying to send to your VZ-1. It is possible that there is something about the file that is problematic--not the midi-ox settings or the VZ settings.

I have a VZ-8m with a dead internal battery so the patches go away at power down. Within the past year I did send sysex patch banks to it, so I know it does work. (I mention this so you don't worry about my losing any important patches in testing your sysex file!)
