brother303 Posted November 17, 2007 Report Share Posted November 17, 2007 Hi folks,finished my mb-fm,not an easy project,but sounds great!Everything is working fine but there is one problem left: It`s impossible to load the preset patches!I use a bankstick-pcb from Mike,stuffed with four ICs,the voltages are ok,the connections are ok,used a multimeter to check this (directly from the pic pins 6+28 to the banksticks). 5V and ground are also ok.Mios recognised and formatted the eeproms and it`s possible to store Instruments/Ensembles/Drumkits to each bank (A-D)First I used 24lc256 from Atmel and switched to Microchip later with no better results.Could it be a midi-interface issue? I use an ESI Neon USB-interface.Any suggestions? ???Greetz Brother303 Quote Link to comment Share on other sites More sharing options...
brother303 Posted November 17, 2007 Author Report Share Posted November 17, 2007 Hi again,I forgot,each time I try to load the presets up,the TL-Patchmanager shows me "Bankstick A not ready".But bankstick A (and also B,C+D) is ready,cause I can store patches to any location on all 4 banksticks.Any hints?.....please!!! :'( Quote Link to comment Share on other sites More sharing options...
doc Posted November 17, 2007 Report Share Posted November 17, 2007 Just for my interest:Which EEPROM did you use as bankstick ?greetsDoc Quote Link to comment Share on other sites More sharing options...

brother303 Posted November 19, 2007 Author Report Share Posted November 19, 2007 Hi Doc,I used 24LC256 from Atmel and MicrochipHi S1,I don`t think it`s a soldering issue. Had a second bankstick pcb here,I checked with both pcbs and different 24LC256. And I`ve checked each connection for shorts or breaks...Perhaps someone here could be so friendly to upload the presets and some random-banks for me,of course I`ll send you some ICs to do this. ;)Would be great!!!ThanksBrother303 Quote Link to comment Share on other sites More sharing options...
doc Posted November 19, 2007 Report Share Posted November 19, 2007 I used 24LC256 from Atmel and MicrochipThey should work ... ???I know, these are other symptoms ... but just to make it sure:You have stuffed your CORE with the both 1k resistors R2 and R12 ?(just a thought)greetsDoc Quote Link to comment Share on other sites More sharing options...
brother303 Posted November 20, 2007 Author Report Share Posted November 20, 2007 Hi Doc,I use a core-pcb from Smash,R4D,have to check the resistors you told me.Yesterday I built myself a single-bankstick-pcb,just to make sure that it`s really not a soldering-issue with my bankstick-pcbs from Mike.Same effect,no cure,still not able to load the presets....I`m going to check the resistorsTHX!Brother303 Quote Link to comment Share on other sites More sharing options...
TK. Posted November 20, 2007 Report Share Posted November 20, 2007 "Bankstick A not ready" will be displayed, if TL's patchmanager doesn't receive the acknowledge message from the core after a patch has been sent.Are you able to overwrite the first patch? This would indicate, that the PC MIDI Out->MBFM MIDI In connection is ok, and MBFM MIDI Out->PC MIDI In is not workingBest Regards, Thorsten.

brother303 Posted November 21, 2007 Author Report Share Posted November 21, 2007 Hi all,@Doc: Yes,the resistors are in,checked and measured,all fine here...@TK:No,I`m not able to overwrite the first patch. When I switch the mbfm on,one upload request is sent via midi out. Mios-upload and the application-upload was successful with MiosStudio,I used the "use feedback from core"-option and all was fine.Seems the midi out is ok?!?GreetzBrother303 :'( Quote Link to comment Share on other sites More sharing options...
TK. Posted November 21, 2007 Report Share Posted November 21, 2007 Are you able to send the patches with MIDI-Ox?Note, that the "delay after F7" has to be set to about 750 mSDoes MBFM return an acknowledge message whenever a patch has been received?Best Regards, Thorsten.

brother303 Posted November 22, 2007 Author Report Share Posted November 22, 2007 Hi TK,the log-window of the patch manager shows me "Midi In:Error Code 01" after sending a single patch to the bankstick.Perhaps this information helps?GreeetzBrother303 Quote Link to comment Share on other sites More sharing options...
TK. Posted November 29, 2007 Report Share Posted November 29, 2007 Error code 01 means "less bytes received than expected".So, it looks like a problem with your MIDI interface. Are you using the latest drivers? Do you have access to another MIDI interface?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
brother303 Posted November 30, 2007 Author Report Share Posted November 30, 2007 Hi TK,no,sadly I have no access to another midi-interface. The driver is new and fresh.But how can it be that mios and application-upload was successful and only the preset-upload goes wrong? It`s all sys-ex,isn`t it??? ???by the way,I tryed midiox with 750ms delay,still the same result...BestBrother303 Quote Link to comment Share on other sites More sharing options...
TK. Posted December 2, 2007 Report Share Posted December 2, 2007 Yes, it's obscure why you can upload an application correctly, but not a MBFM patch.You can check the reliability of your MIDI interface the following way: create an external feedback loop (MIDI Out->MIDI In) on your PC interface, open the SysEx tool of MIDI-Ox, load the patches into the command window, press Command->Send/Receive SysEx, and thereafter compare the dumps with the SysEx->Compare function.If MIDI-Ox finds errors, you know that the MIDI interface is the reason.Another point is, that you could have overlooked a programming error during application upload. So, just to ensure that MBFM is complete, upload the application again, and doublecheck that all code blocks have been acknowledged without an error message.Best Regards, Thorsten.

brother303 Posted December 3, 2007 Author Report Share Posted December 3, 2007 Hi TK,yes,it`s a mystery...I`ll check my midi-interface with the method you described above,let´s see what will happen. And of course I try again to load mios and the fm-application to check there are no errors.Stay tuned!GreetzBrother303 Quote Link to comment Share on other sites More sharing options...
brother303 Posted December 27, 2007 Author Report Share Posted December 27, 2007 Hoooray!!!I`ve done it and it works!!!My midi-interface was the source of trouble. I got myself another very cheap interface,plugged it in and the preset-upload was a piece of cake,no probs anymore!I´m using this interface here : http://www.thomann.de/de/search_dir.html?sw=swissonicLike I said,very cheap,but it even works with my nord-modular-editor without any problems... ;D Quote Link to comment Share on other sites More sharing options...
TK. Posted December 28, 2007 Report Share Posted December 28, 2007 Good input! I suggested this MIDI interface multiple times in the past, good to know that it works reliable :)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
