LP wont recieve sysex data

Hi all!

I bought my Little Phatty 3 days ago now, and for the last 3 days (after work) I have been trying to get the sending and recieving Sysex data thingi to work.

As i am a noob with Analogue synths (the LP being my first) I dont want to loose the presets so i decided that before i save anything i would back them up and get the sysex stuff all working.

Ihave successfully dumped sysex data to my pc using MIDI-OX. and when i went to load it back onto the LP, it all looked as though it went fine.
The LED display says all the “recieving data” thing, but when i go to the actual presets, they are still the same as before!

Is there something i need to do to the LP to get it to accept or overwrite the data?

If someone has any idea at all of how i might load up the sysex data, it would be greatly appreciated.

Thanks

Hi, maybe I am not understanding your problem…
but if you saved all the patches as sysex, and then turned around and sent that saved sysex back to the LP. wouldn’t the patches have to all be the same since you haven’t changed anything?

Try renaming a patch and saving it on the LP and then re-load the sysex data; see if the patch has the new name or if it reverts back to the old one. If the name changes back to the old version, then you can assume that the sysex transfer to the LP was successful. If I am missing something about your situation, please clarify. Thanks!

Thanks for your reply amos.

Yes sorry i forgot to say, I did rename one of the patches and it didnt change it back.

But just this morning i tried re-installing my USB/MIDI connection driver. The problem has now been fixed and it works perfectly.

My computer musn’t have been detecting the USB/MIDI connection properly.

Thanks again

I’ve been fighting with midi-ox this evening, and if I try to restore a whole dump, it acts like it’s working but the patch names are all corrupted.

saving and reloading individual sounds seems to work ok

any ideas?

to rephrase my question: has anybody successfully done an ‘all presets’ restore using midi-ox to phatty OS 1.02d?

Thanks,

Hi Craig,

I will check this out here and see… I believe I tested this successfully though. If you haven’t increased the buffer size in MidiOx I suggest you try the following settings:

In MidiOx, go to the Options menu and select “Configure Buffers”

For both Input and Output buffers, set Size = 1024 bytes, Num = 128.

The LP sends large chunks of sysEx data at a time, and having insufficient buffers to hold the data in transit can cause problems. If this doesn’t help, let me know.

Cheers,

Amos

thanks, but that does not help..

often the first few presets appear correct after the dump, but later ones have garbled names, and some of the colored buttons are a rich, dark red color, and certain stages have no lights at all.

i should also clarify that I never tried this on 1.02c, so it may have never worked here.

Hi,

I just tried this with a different midi adapter (my NI Kore controller, instead of my motu traveler) and it worked fine!?
