You don't need a midibox for this. Just connect the DB50XG to MIDI with a simple circuit: http://www.compuzik.de/Download/DB50XG_Exp.zip (German - from the c't magazine) And here the pinout of the DB50XG connector: http://atari.nvg.org/db50xg/ Raphael

Minimum is one SID and one CORE module. For 3 SIDs you will need 3 SID modules and 3 CORE modules... without CS of course .

Klar geht das ;) Schau mal hier: http://www.edrum.info/ Oder such einfach mal nach EDRUM im Forum.

Analog outs? Or is AOUT support part of the application and not a MIOS feature?

Hallo Torben, Grundsätzlich möglich schon... aber wie Thorsten schon sagt nicht einfach. Bedenke einfach mal, dass Du bei einem 4in 1 Merger die Daten von 4 Midi INs durch eine Midi OUT quetschen musst. Das ist schon theoretisch unmöglich, Wenn auch nur auf 2 MIDI INs die volle Bandbreite genutzt wird....

Here you find the specification of the MIDI protocol: http://www.borg.com/~jglatt/tech/midispec.htm

Depends: I have already a lot of electronics stuff at home (e.g. some thousends of resistor in nearly every value and so on..), so I only buy the PCBs. If you have nothing at home I would buy the kits. I don't think buying all the stuff seperately will be cheaper unless you buy big amounts of each part (e.g. 100 resistors of the same value). But you don't have to buy the kit to get a PIC with already burnt bootloader. SmashTV sells also single PICs with bootloader. Depends on the parts you use. Some switches cannot be mounted on the panel but have to be soldered on a breadboard (the hole-board ;D) If you use breadboards you should verify your desing twice. For tips just look around in the forum and on other DIY sites. You mean the buttons or the button functions? The functions are allways the same (unless you add sone extra functions to the firmware). I think the SEQ is easier, if you compare it to a SID with CS. Not so many PCBs. For a full stuffed MBSid you have 4xCORE, 4XSID, 3xDIN and 2xDOUT. A lot of boards to solder... On the other hand: With the MBSid you can start only with one CORE and one SID and the enhance it to the big version with control surface. Raphael

Most expensive is the panel. So I did mine by hand... just finisched it today. The other expensive things are the LCD displays. On Thorstens page he writes 49 Euro (2x40 two times). I got my two displays for only 20 Euro in a surplus store. So just look around and you will find cheaper stuff.. Raphael

Just have a look at the SEQ site and add all the costs given there by Thorsten for every module. http://www.ucapps.de/midibox_seq.html Sorry, I've no knowledge about moebius' SEQ...

Welcome Duncan, If you have soldering skills, there should be no problem. There are no SMD parts in the MbSEQ project! You can order PCBs from SmashTV (http://avi.dezines.com/mbhp/buy.html). His PCBs have a silkscreen print so it's really hard to do some bad solderings... Instructions on the ucapps site are really good. Just solder one module after the other. All modules are explained in detail on Thorstens site. And if you have any questions after reading the instructions... Hey, the midibox.org Forum is your friend. Raphael

No, I`m not involved. I just saw the JAL project on the net and a friend of mine uses it for some home automation stuff. If you read the text carefully, you will notice that bcbox uses a "M-Audio Firewire Audiophile" http://www.m-audio.com/products/en_us/FirewireAudiophile-main.html This is no PCI card. It`s hooked up to your computer via Firewire.

No, PIC is way too slow... Just compare: PIC works with 10MHz (40MHz internal). PCI-Bus (for Sundcards) works at 33MHz. I know only one project to use a ISA-Networkcard with PIC... no soundcards.

Hey moebius, For me a "card" is something with PIC/ISA bus. That's why i was asking.... gbeth wrote: For example bcbox integrates a M-Audio firewire interface: http://69.56.171.55/~midibox/forum/index.php?topic=4490.msg30572#msg30572 But only the MIDI part is connected to the MidiBox core, the audio part is standalone...

What audio cards ???

Hi, You can remove the "dents" from normal encoders (for instance from SmashTV or Voti). See this Topic: http://69.56.171.55/~midibox/forum/index.php?topic=3299.msg26675#msg26675 I've done it with the encs from Voti several times. Raphael

Licenced yamaha technology in the CT chip? I don't know exacty, but some Crystal soundcard chips had a OPL-3 clone inside... Thorsten gave the answer. The newer the windows version, the cheaper the sound... When Win95/NT came out OPL was already "overtaken" by wavetable soundcards(I bought my AWE32 in 1994, WIN95 came out in '96). Wavetable and the first onboard effects were in. So the driver programmers just kept some OPL sounds for compatibility and didn't invest too much work in the "old" OPL sounds :(

You mean YMF262? No, all AWE cards (even the oldest ones) have a EMU chip on it. No more OPL. Original OPL cards sound the same with all OS. But you are speaking of an AWE card. With my Creative AWE32 cards it depends on the driver. Even Win95 and W2K sound different (in my opinion).

You're speaking of MBSID and MBFM? A SID only has a analog out and sounds somehow LOFI (yaeh, it's part of the famous SID sound). So why construct a costly ADC when your soundcard has a good one? Same for the FM. (With some investment it would be possible to convert the YMF262 output to SP/DIF, but the YAC512 is part of the OPL3 sound too.) Better to invest the money in a semi-pro sound card. So you can capture every analog sound in good quality.

You are right. These are old stock. Take a look at http://www.synthtech.com/cems.html They are selling their last CEMs at the moment.

Hey, hey, hey!! This community is stricty noncommercial! The copyright to all Midibox designs belongs to Thorsten Klose. Respect this!

Probably never... There is a silicon bug in the latest revision of the 18Fx550 PICs. Read this forum article: http://forum.microchip.com/tm.asp?m=85120 BTW: I've already soldered two AN2131SC modules without problems (Ok, soldering is not so easy ;)). And they have two MIDI INs and OUTs!

Why not building one of these: http://www.ucapps.de/mbhp_usb.html http://www.ucapps.de/mbhp_usb_pic.html (not working at the moment...)

Hi, A hex file is the already compiled code. Just install MPLAB from microchip and use it like described here: http://www.ucapps.de/howto_tools_mplab.html http://www.ucapps.de/howto_tools_mpasm.html (It's free!) No They are ok. I use them in my SEQ. The only disadvantage is that you sometimes unintentionally turn the knob when you just wanted to press it... CV is no problem. I never used more than one channel (Never needed more...). Raphael

Wie sagt Thorsten immer: Der Schaltplan stimmt immer ;) 2200uF ist in diesem Fall (Sieb-Kondensator) auch besser.
