Hello, I've done this midibox several months (oops... it's years, now... !) ago, but now I have bought (much more expensive) real analog synths, and I don't use it anymore... It is designed to control a Minimoog VST Plugin (ex: Arturia Minimoog V, or other free versions) If somebody in France or near Strasbourg is interested, please mail me. (or anywhere else, but I think the shipping will be expensive...) My mail : basquin at freesurf dot fr. IMGP1695.JPG

For sale : a homemade Midibox (Minimoog controller) and Commodore 64
jeb replied to jeb's topic in Fleamarket
Hello, I was not offended :) Best regards, Joseph -
Hello, Comme j explique ici : http://www.midibox.org/forum/index.php?topic=10352.0, j ai construit un controleur qui marche etc. mais je n ai plus de place ni l utilisation etant donne que j ai achete un vrai synthe analo. Du coup a vendre... J ai des photos si interesse. Suis en Alsace. A bientot jeb ps: je precise que c est pas du tout une activite commerciale c est juste une vente d occase !

Hello, > You post your fancy new controller on 2007-12-10 > and want to sell it on 2007-12-16? It s not a new one ! I have built it about 1 year ago as I said in a previous post. It is fully functional. But the thing is that I have recently bought a real analog synthesizer... I recognize it is difficult to sell something I have personnaly created, spent time on it, etc. but I do not use it enough and I have very little space... So... jeb

For sale : a homemade Midibox (Minimoog controller) and Commodore 64
jeb replied to jeb's topic in Fleamarket
Hello, About the Midibox, it is MB64, with lots of pots, designed to control Arturia Minimoog or any other VST : there are exists **free** Minimoog VST. It IS finished and fully functional. I spent more than 100 euros for electronics (with shipping, wall adapters, and misc.), more than 50-60 euros for pots and knobs, 40 euros for the case wood making, imitation leather, etc. And really *a lot* in misc things that I even cannot remember. You can mail me to do a proposal : basquin at freesurf dot fr. Joseph PS: TK, Why do you find it strange ? I explained I ve done it *not for commercial purpose* (I only sell this one !!)... The problem is indeed that I have bought a real analog synthesizer and that I do not need this one anymore... (Moreover I do the same now as I did with my LEGO as a child : I enjoy *building* a unit, but then I less enjoy *using* it, and I go to another (currently not an electronic one) project ...) -

here you can see some photos on the thread in the "midibox of the week section": http://www.midibox.org/forum/index.php?topic=10317.0 jeb -
If somebody is interested, I sell it now... ! It's working great, but I have now bought a real (much more expensive) analog synth... and I have no more space in my 2-room apartment... You can contact me here : basquin at freesurf dot fr. I'm living in east of France, near Germany... jeb

in french we call it "skaï", it's imitation leather... 6 euros/meter.. here another close up picture : IMGP1695.JPG

yes... leather... :)

hello, i've made several small midiboxes (one year ago... see my other post)... i'm currently building a new one, and i have one or two small questions... 1) what range has been tested for power ? is 12V AC ok or too much ? 2) is there an interface for a power led (i don't want to build a ?OUT module for this!) 3) i have 50 kohm faders... will it be okay ? i remember i had problems with 100k pots... will these 50k be okay ? if not, i don't remember how to make them work (i cannot replace them for my specific project!!) WITHOUT jitter... any idea ? thanks in advance!

Hello ! A "Minimoog" VST controller Midibox.... Jeb IMGP1707.JPG
-
hello, thanx a lot. a multiplexer would be good for me (much cheaper !! and easier than building a complete core with a PIC...) could you just give me the name of the chip needed (74?? , 74157 ?) and then i promiss i will do it by myself without asking any questions.... ;) thanx jeb
-
thanx a lot for your response ! how to use a digital multiplexer ? (which reference?) which pins are to be connected ? with this solution, will it be real merger ? or is it a solution only when we are sure that the MIDI messages from the 2 MIDI IN do NOT come at the same time ? thanx in advance ! MIDIBOX is great !!
-
hello, 1) what happens if i connect the 2 outputs of the 2 octo-couplers (one for each MIDI In) to the same core ? pin 6 of octocoupler 1 (MIDI IN #1) \ ------------- pin 26 of PIC18F (pin RX) pin 6 of octocoupler 2 (MIDI IN #2) / will it work if i'm sure message won't come AT THE SAME TIME (from the differents outputs) ? 2) if i do : pin 6 of octocoupler 1 (MIDI IN #1) ---> pin 26 of PIC18F (pin RX) pin 6 of octocoupler 2 (MIDI IN #2) ---> pin 6 of PIC18F (pin RA4 like for the merger project) I want to use the inputs NOT BOTH AT THE SAME TIME. how to tell MIOS that MIDI comes from pin 26 or pin 6 ? 3) any other switching option ? apart putting a mechanical switch (that's what i've done!) ? jeb
-
hello, ok if this doesn't work... in fact i don't need to merge 2 inputs... i have to use MIDI IN #1 at a certain moment and MIDI IN #2 at another moment. but never both at the same time. in fact i'm looking for a solution that allow me NOT to unplug one cable and replug another... that would be boring.... is it possible to select one of the two MIDI IN ? (not to merge them if not possible) with a button for example or dynamically in the code that would ""switch""" the input. for the moment i have done it with an inversor (mechanical) switch but it's a bit boring... i would like to switch it from the code .... jeb
-
hello, i have done a midibox (with my own program based on the midiinout128 example) with pots, buttons, etc. i want to add a secondary midi input that will be merged with the first one. i did like in the midi merger project : RA4 (from the PIC of the core, i.e. pin #6) to a second optocoupler with resistors, diode, etc..... do i have to remove the R2 1K resistor if I use the second midi input ? because there is already a 1.2K resistor between PIC RA4 and 5v (provided by the second MIDI (optocoupler, etc.) module (see midimerger.pdf)).... what do i have to add in the code ? thanx jeb

Hello, Do you know any website or pdf or book with FM presets ? I know there are lots of preset, banks, .syx, etc. for dx7 on the web etc. but i would like to have a paper version of the patch in order i can "feel" a bit how to create beautiful sounds... (open each preset with a DX software + screenshot + print would be a bit long....) Do you know any FM Patch Book ? Thanks
-
thanks a lot Wilba !!! but MIOS_HLP_Dec2BCD brings me wrong value in MIOS_PARAMETER1, MIOS_PARAMETER2, MIOS_PARAMETER3... for example for x=100 (unsigned int) PAR2 = 0x56 ?? PAR3 = 0x00 ??? that's strange ! i've read a previous post about issues about Dec2BCD but i didn't really understand what was the conclusion !! thx,jeb
-
Thanx Lall ! The idea with << for the double switch is great !!!!!! My second value is only 0 or 1 so (<< 1) is enough ! between : switch ((i<<1) + j); { case 0x010: //-> corresponding to i = 1, j = 0 case 0x011: //-> corresponding to i = 1, j = 1 ... case 0x031: //-> corresponding to i = 3, j = 1 } and switch (i) { case 1: if j then ..... else .... case 2: if j then ..... else ... ...} which is better in terme of time consume ? thanx
-
hello > The pointers would be even slower than the switch statement that's not possible : the pointer to the function is *changed* only when a button is pressed (so in the call of DIN_NotifyToggle), so not so often at all ! the pointer would replace a // switch (mode) case 1 : Function1(); ... // by a // Functionptr(); // where Functionptr points to Function1, Function2, or Function3. is this possible in C ? how to do a pointer to a function with SDCC ?

Hi, thanx for all answers. I have read the libsdcc.lib README.txt from TK !! > 1) printf prints a string to the console/a file/the buffer. > what console/file/buffer exactly do you want to use on the PIC18F? sorry, i wanted to speak about "sprintf" which outputs not to the console but to a string. but the problem is the same when i use for example "memcpy", even with the libsdcc configured as in the README.TXT... regards, jeb
-
hello there is a problem with the linker, even with libsdcc.lib in /lib and set up in the .lkr file. always the same problem : error: missing definition for symbol "_sprintf", required by "_output\main.o" i can include : #include "sprintf.c" but then it is another file that makes problem : _vfprintf then i include : #include "vfprintf.c" then it is another one .... then i include the .c file then another one... this can continue very long ! is it normal that one should include all these .c files for the different functions when one needs to use a function ???! ??? i gave the example with printf, but with memcpy, etc. it's the same ! thanx
-
hello, even if it worked, printf is too big for the simple need i have. so my problem is simply : how to do a division par 10 or 100 ? (in order to isolate the different numbers in decimal writing!) (asm optimized?) thanx
-
hello, i have several "modes" in a global variable : unsigned char mode; and the value of "mode" is changed by pressing some buttons. I have : function Tick() { switch (mode) { case 1 : Function1 (); break; case 2 : Function2 (); break; case 3 : Function3 (); break; ...} } aren't these tests (with if, switch, etc.) every times Tick is called (so very often !!) a waste of time ? is it possible to do pointers to functions ? example : pointer ... mode_functionptr; whose value is changed when the button is pressed. with then : function Tick () { mode_functionptr(); //without tests! } ///////////////// just another small question : how to do a "switch/case" on two variables ? is : switch(i,j) { case (1,0) : ... case (2,1) : ... ... } possible ? thanx in advance !
