Hi, I'm still coming here from time to time to see how things are moving forward ;-) I learnt so many things from Thorsten work. The 24LC512 and 75HC165 wiring of the PreenFM come directly from the midibox. The audio output do not come from a DAC but from a 1 bit digital output at 72Mhz low pass filtered. Xavier

OK. thanks for the clarification :-) Maybe something like : "6 four operator voices played by 4 simultaneous different instruments plus drum kit." Xavier

WOW... Impressive.. Congratulation for this beautifull little box. I'll definitely have to order one... maybe next month. I'm surprised to read in the feature list: "4 simultaneous instruments of 6 voice polyphony each, plus drum kit. Each voice is a 4 operator waveform." That makes 24 voices of 4 operators + drum kit ?? That sounds much more than in the opl3 spec: "6 four operators melody sounds + 3 two operators melody sonds + 5 rythm sound". Did i miss something ? Thanks, Xavier

Vendu... Merci.

Vendu Bonjour, Je vends le lot suivant (tout ce qu'il y a sur la photo a part le tournevis qui traine) : http://xhosxe.free.fr/pic/LotMidibox1.JPG La midibox FM est pleine...

Thanks... My goal was to have everything public in the spirit of all those midiboxes. So i documented as much as i could here : http://www.midibox.org/forum/index.php?topic=7569.0 A compiled firmware would be useless because my Dout and Din wiring is very bad and weird.... But i see no problem in sharing it. If you have any question, don't hesitate. :D Xavier

Thanks a lot ! I agree that many things could have been better/nicer. ;) I just wanted to add that this is my first DIY project and i could mod it a little thanks to the excellent Documentation !!! Xavier

Hello, After a big break doing other stuffs, i finaly found time to finish my mini midi box SID. Much less nice than i expected, bad varnish, box not totally closed, flashing screen etc... Anyway it works and i am happy. I can control every parameter rather quickly ;D Xavier

Hi Talion, That's great to see your beautifull work ;D I absolutely must find some time to finish mine... You should have sent me an email to know what's missing.. But you found exacly what was missing.... congratulations. Sorry for the problem and thank you to have posted the fix : (For the record the missing line is "CS_MENU_ButtonIncDec_End" at the end of CS_MENU_ButtonInc function in cs_menu.inc.) Please post a picture of your finished box. I'll do the same.... ;) Xavier

Thanks for the reply but i don't really get what you're talking about. regulator ? you mean the 7805 ? I followed the typical Midibox schema.... I'd just like to know wether i'm the only one to have this problem... in this case i will try to investigate a wiring problem. If it's a known problem, i will be OK with it. Regards, Xavier

Hello, After some time turning the knobs i have some noise synchronized with the parameter changes or simply with the cursor flashes. It often geting louder and louder and start being real sound... often drums.... Sometime the opl3 seems to become instable and a very loud sound starts which does not stop untill i turn off the box. Then i turn on and every thing is fine... Does anyone has that kind of problem ? Did i solder something wrong or is it a known problem because of the pins which are shared between the LCD and the opl3 module. Thanks for your help, Xavier

Thanks... I'm happy you like it.... :) Answers: 1 - the case is a teko 364... Arround 20 euros in france.. plastic box + aluminium surface. Available every where... I painted the plastic part in black... The original color is not very sexy. I also added some feet to make it nicer and more stable : 2 - What is the english word for that : a "cutter" in french... It took me about half an hour for all the wholes.... But it was not perfect. 3 - Lazertran (ink jet) becomes totally transparent (where there is no ink) after the second coat of varnish. 4 - No.... I can do it tomorow with the light day if required. If you mean the joint just at the left of the matrix... it is not very nice... Xavier

See the "CC" button here : http://www.ucapps.de/midibox_sid_csB.html Don't remember wether it's reachable from the menus... Xavier

No problem... when my box is finished and when i'm sure everything is OK. You wouldn't want a shaeffer layout in which you cannot put the knobs and buttons... ;) Xavier

Hi, I'm glad to see some interest in this Mini-midibox... Thanks a lot for the support. I haven't finished it yet.... I'll have more free time this week end so it should be finished next week. To know the number of 74HC165 (DIN) you need, count the knobs (as 2 inputs) and the button (1 input). You can plug 8 inputs on a DIN... You'll have your number.... Answers to your question... 1 - In the last version if my box, there are 6 knobs and 23 buttons. So 35 (12+23) inputs = 5 DINs. 2 - Of course, it is possible to chain more than 4 IC like as shown in the DIN4x pdf.... up to 16 i think. 5 DINS allows 5*8 = 40 inputs... My version only use 35 so you have 5 free inputs... you can add your 4 buttons. You can use a DIN4x module and add after it a single DIN. Note : the modulation part : 10 buttons and 8 leds is optional and independent from the rest. Other question or remakrs are very welcome, Regards, Xavier

Hey... I'm glad and proud to see my midibox here... thanks Thorsten. ;D There seem to be very few Midibox FM compare to SID... Too bad... In fact the 4x20 LCD works rather well. The 2 rows of 4 buttons bellow the LCD is intuitive. no problem to find immediatly which button to press. The more weird is the scrolling of parameters with the first menu of the second line which become the 4th of the first line when you scroll right...etc... difficult to get used to. Concerning the main page "Instrument view" is not nice but "full view" (see CFGmenu) is really perfect... Can be specified as default in the main asm file #define CS_MENU_DEFAULT_VIEW_MODE 0 Xavier

I received the transformer to replace the noisy wall adapter and it is much much better. But i ordered a 7,5V transformer and after 2,5 weeks of waiting and many emails i received my order with a 12V transformer inside... I will never order to alscomposants.com again... French people, avoid that site... With 6 diodes before the 7805 and a heatsink, it seems to be OK. My midibox FM is finished... I spent many houres of fun... It was very interesting... Thanks again thorsten. Here are the last pictures : Before closing the boxes.... All the wires were uselessly too long exept 2 which were really too short.... Next time i'll spend more time trying to cut them at the right length. Closed.... This big box to control the tiny OPL3... strange... But i like very much how it sounds !!! ;D No back to my "little surface, maximum control" SID... And then maybe i'll do some music again. Xavier

Thanks... I'm glad you found it usefull... No you don't need the modification of the other thread, only the modifications of this one. Don't hesitate to tell me if something is not clear in the message that shows the modifications. Xavier

Hi thorsten, I found so many usefull things while searching in the forum, i like when people write down what they do/find. That's why i try to do the same. I added a link in the WIKI page you mentionned. Xavier

Thanks for the suggestion... The following of this project is here ;) http://www.midibox.org/forum/index.php?topic=7569.0 Xavier

I think that's it. Hope this made a readable message.... At least i will be able to read it again in the futur if i didn't remember the mods i made.... ;) Regards, Xavier UPDATE : current control surface design.

While i'm waiting for the new transformer of my midiboxFM to be able to finish it (the old cheap one make awfull background noise).... I had some time to work on this "little surface, maximum control" project... The code is finished and every thing is working fine... The code to write was simpler than expected. The encoder function tables fit perfectly this design. My CS_MENU_ENC_CS_Handler function is very very simple If some are interested i'll post the files i modified... There are lots of empty cells that can be filled with custom functions very easily. (The printing on the picture is not the last version of the design but helped me to check the buttons/knobs....) Still a little work to do on the control surface design and a lot of work to put that in a closed box !!! but that works !!! ;D Xavier

I think you wrote this FAQ to avoid that kind of question... Sorry... And thanks for the answer. Xavier

Thanks Thorsten for the FAQ which is very usefull... and clear. But i was surprised to read I haven't tried yet the CC button (step B) with my mono SID but i have the feeling it will make the bug appear... Can you tell me if the followin is true ? You play a midi track routed to the SID box with a sequencer... and then use the CC stuff to record with the same sequencer some sound modifications while it plays. The bug may occure (??) Regards, Xavier

Thanks.... :) No change at all ! Line 1&3 corresponds to line 1 of a 2x40 LCD. Line 2&4 to line 2. I may try to change something but i'm afraid that will not be simple : It is that when you scroll the menu with the main encoder all the screen scrolls and it's weird... It would be much nicer to have only the second line scrolling. The main page also is weird with the '|' at the end of the first line (you can see it in the first post) ... Removing this "|" and putting 2 spaces instead of 1 between the instruments would be nicer. Xavier
