Looks cool! What exactly is this? And is it really only 25$ ? Is this a possible answer to my microcontroller synth programming inquiries? sorry, I just started reading some microcontroller programming books yesterday, so maybe I get something wrong EDIT: I see now, the price is in UK pounds, exclusive VAT ;)

When looking at that Zoner sceenshot, it really seems to be similar to Inkscape. I just switched inkscape's background to black :D

Welcome to the midibox forum! Sounds like the DOUT with its 5VDC is suitable. I am not an expert though, maybe the current is not enough? One DOUT output can supply up to about 25mA as far as I know. Whatever that means...

That's a new level.. I would love to hear the small drum BTW, it reminds me of http://createdigitalmusic.com/2008/03/16/weekend-inspiration-coke-bottle-as-tribal-percussion-and-the-future-of-adaptive-music/#more-3156

Interesting! Yeah, that Chameleon is sort of what I was thinking of. A programmable rack unit. The idea about using an old PC as rack hardware I had too, but wouldn't then many workarounds be neccessary? For example - additional MIDI interface - additional sound card for reasonable quality and maybe multiple outputs - control surface based on MIOS to control rack over MIDI as well as receive parameter updates Also, it would not really be the DIY fun thing anymore, with self-soldered PCB, programmed PIC, and so on. Just some thoughts. Since I am observing that people start programming synths with Arduino, or do the SwinSID, AVRsyn, AVRX, I thought maybe Csound could be converted into C routines to program such a synth.

nice! did you recall this after watching that yellow drum machine video?

Yes yes. Csound Csound. Steep steep. But my intention was, could Csound be converted into some Assembler or C stuff or whatever you programmers call it, and then run on a PIC, AVR or whatever you programmers call it? Today is repetition day day! :D

I just post it here... I read somewhere how the makers of Csound were discussing using Csound to program custom DSP hardware stuff. I think Barry Vercoe called it extended Csound. Has anyone an idea how this thing went, or any news about it?

Wahrscheinlich tritt ein Error auf, wenn er keine HEX Dateien ausspuckt. Öffne mal die Eingabeaufforderung und führe make.bat aus. Lies was make.bat bei der Ausführung schreibt. (Wenn du es von Windows aus ausführst, verschwindet das Fenster ja sofort wieder). Schau dir auch mal die LST Datei mit Notepad o.ä. an, ganz am Ende steht sowas wie "total errors: 0" oder so.

BigDog scares me too. It sounds like a giant "africanized bee"

ima tri?

annyong haseyo, sorry I dont understand Korean. :)

Nechal jsem si plech udelat u Schaeffer Apparatebau v Berline, to bylo mastny jak skvarek, ale to jsem jeste nevedel co a jak, a myslel jsem si kdyz vezmu ten TK-uv layout, nebudu moct delat hodne chyb. Az pozdej me napadli zmeny layoutu a dostal jsem chut navrtat plech sam... Ty fadery tady uz taky mam dlouho, koupil jsem je protoze my ve forumu odpovedili "You could use non-motorized faders, but it would not make sense. Read in the forum why." a nikdy jsem nenasel "why"! Tak, zaplatil jsem tolik, ze by me to bolelo kdybych LC nezkoncil. (Omluvte chyby, narodil jsem se v nemecku. Tvrde a meke i jsou moje nepratele)

It seemed to be a damaged YMF262. I soldered another one and it seems to work fine now. Still making an OPL3 bulk order to have enought spare chips though :D Thanks TK

THAT got soul!

Zajimavé! Jak budes implementovat ten "global quantization" encoder a jeho LEDringy?

Boze! Happy soldering... Ja stavim MBFM a MBLC... Fotky budou tady: www.flickr.com/photos/disgustingpie Tvuj design se mi líbí!

Another beautiful detail is how nice the 2x16 LCD fits into the middle area of the smaller SID.

I love those Mini64 buttons! Especially their labels, and even the BLK, WHT, RED... labels. You can teach friends or kids: "for this sound push black, then cyan, then adjust red to 64." :D

After some testing: the problem has to be between LCD and OPL3 module... All voltages fine, core + LCD work when OPL3 module not connected. As soon as OPL3 interconnection connected, LCD hangs up and "noise data beeps" (reminding me of a very aggressive vintage modem) on the outputs. I will check the YMF262, maybe it became too hot while desoldering... I have a spare one left.

Hi, my MBFM (second approach) is weird. - see topic. If LCD connected, then after power on -> Beeps and white noise at full scale. Mostly noise all the time, plus the notes I play, if I do. The LCD shows all boot stuff regularly ("MIOS 1.9f", and so on), then freezes at the main screen. (if I change patches, no changes on LCD) - Without LCD connected -> No white noise, but I noticed that every six notes I play, three of them are distorted (desoldered too hot OPL3 chip I guess, so maybe three out of six voices got damaged?) hmmmmmmmmmm.............

His question: Which parts should he mount and which leave out? Umm... yes. The same question in Chinese. Hope we can help this guy together. I understand Chinese but have no experience with the USB PIC module. Hope you guys can explain.

TRANSL: "I found the problem, [umm....... whatever. anyway, he found the problem!] Another question: I like to cross-connect USB PIC module with the core. I removed the 6N138 on the Core, but do I need to remove R6 (1.2K) ??? My USB PIC module already has 6N138 as well as R3(1.2k). [OK, that one had no need for translation!]

TRANSL: "I already built MIDIBOX64 and MIDIBOX LC, with a LTC module. Now the question is ? I need MIDIBOX LC's control buttons ?48buttons) but I also need 64 faders from MIDIBOX64, as well as he LTC module and the USB module. May I ask how can I make a concrete design, can I combine logic control buttons and 64 faders of a MIDIBOX64 to control the PC software? PS: I already tried to control PC software, the MIDIBOX64 button use [i.e. using the MB64 application i suppose, akcija] had problems [he wrote that the pots worked well but MIOS hung up as soon as he pressed a button and LEDs all lit up, lots of random MIDI events arrived at the PC], but if using the MIDIBOX LC app, buttons do not have problems [the buttons work well], but I then I of course have only 8 faders. I built the USB module with a PIC18F4550, probably that is the problem, should I use AN2131SC?"

I think know what xixi means. His native language is Chinese, in which the words "problem" and "question" are quite one word. That's why the online translator writes "the question" here and there, funny! I will write him and try to translate his problems in this thread, then translate back.
