  3. cheers, bhc303 Today I got my 2 x Mos 6581 chips. And both of its are look fine ! Thank you very much ! Best Regards, Janis
  4. I prefer a PNP-transistor type BD136 or similar Regards, Janis BD136.pdf
  5. I saw the encoder settings for the MBFM made by me : #define CS_MENU_ENC_SPEED_VALUE 3 and by the type : MIOS_ENC_MODE_DETENTED2 for all encoders Regards, Janis
  6. In a setup_mbfm_v1.asm file you can find more info about encoder types and encoder's speeds Can you upload some pics of your soldered OPL3 board both sides ? Regards, Janis
  7. How hot or warm is the +5v IC I do'not know, but to screw on it to a heatsink I want to recommend anyway. Your 9Vac 400mA power supply looks very good ! Another ICs in normal conditions are never be very hot. Quantity of banksticks are more for future possibilities. You can try with Pic18F4620 too, i am not sure your PIC18F452 is damaged. In earlier post you wrote: "I tried adjusting the volume for each instrument and operator to zero and I was still getting audio with no change in volume. " Are your MBFM CS is working properly or i did not understand something? May be somewhere are connection mistakes ? Regards, Janis
  8. The Pic18F452 is correct for MBFM. I am thinking about 5v power supply part . Is it stable 4,9v as echo wrote all the time and the +5v ic is not so hot ?
  9. May be you can find some more usefull info in this : topic Regards, Janis
  10. From Wiki pages : Can you connect multiple SIDs in parallel to one Core, to get a "unison" kind of sound? Yes, this feature is available starting with the MIDIbox SID 2.0. Is this next piece still relevant? As TK says: you can connect multiple SID modules to one core module, in this case they always listen to the same control data. But the audible effect isn't really so interesting. If you are having two identical SIDs, then the volume will just be doubled (the oscillators are digital and therefore always output exactly the same waveform). This option can make sense if you want to switch between 6581 and 8580 because of the different filter characteristics. But for really interesting (especially fat) sounds, seperate cores are the best option, so that the SID parameters are modulated independent from each other. The result is much more analog-like(especially when the LFOs are in freerunning mode and the finetune/portamento/ENV parameters are slightly different). Can we have more SIDs in one MB SID? TK: As always I have to define such specs before beginning with the implementation. First I thought that controlling two SIDs from one control surface is sufficient for stereo effects. Then I was possibly in such a volatile temper that I decided the incredible: controlling 4 SIDs from a single PIC, which is doing the sound engine of one SID in parallel! Hard to believe that this works without affecting the realtime capabilities too much. I'm really proud that it works without trouble. However, if you really want 8 SIDs, TK suggests: you could build two 4*SID systems… this will possibly cost you 50 EUR more, but what are 50 EUR compared to my unpayable sparetime I'd go with that suggestion
  11. I found this info : Hint: it's possible to give each MIDI port it's own name by editing the [strings] section in the midibox.org_gm5.inf file. Example: WDM.MIDI_1.szPname="MIDIbox SID (1)" WDM.MIDI_2.szPname="MIDIbox FM (2)" WDM.MIDI_3.szPname="MIDIbox SEQ (3)" WDM.MIDI_4.szPname="MIDIbox Stribe (4)" WDM.MIDI_5.szPname="Keyboard (5)" <P class=INFO>This helps you to organize your MIDI ports, so that they are easier to find:
  12. More outs, more fun: from the OPL3 article: " The DAC outputs are directly connected to the YAC512. Sound cards are mostly stuffed with only one YMF/YAC pair (I've never seen a card with two YAC512) which results to 2 audio channels. With an additional YAC512 four separate channels are available, which is especially useful if the outputs should be routed through different external effects."
  13. In a photo in the OPL3 article you can see four stereo sockets for the opl3 board audio outs, but in reality it is quite enough with the four mono sockets : http://ucapps.de/mbh...connections.pdf Regards, Janis
  14. I think it is not possible to use push-buttons in a AIN module. But in the MBHP core section which refers to J5 port, you can find a some more info about usage of this port : " There are also some application which use this pin as digital in- or output (mostly described in REAMDE.txt or setup_*.asm file) " Regards, Janis
  15. - Linear pots or faders are required for MIDIbox ! - so close : ~ 12k value are not so critical. Will be OK. You can place this capacitor in any direction. I think , No ! May be missing connections or some shorts . The bigger enemy is static electricity. Regards, Janis
  16. Have you looked at the Midi Router project? http://www.ucapps.de/midi_router.html midi thru ports : http://www.ucapps.de/midibox/midi_thru.gif http://m.bareille.fr...midithrubox.htm Regards, Janis
  17. Hi , Antix May be I am wrong, but this part of code in setup_808_default.asm file is define SR drum trigger outputs : ; Following table allows you to define; - the track names (must consist of exactly 6 characters!) ; - the DOUT shift registers (SR) to which the drum triggers are connected ; (1-16; 0 disables assignment) ; - the DOUT pin to which the drum triggers are connected (0-7) ; - the MIDI output port (0=disabled, 1=Default, 2=Internal, 3=IIC1, 4=IIC2, 5=IIC3, 6=IIC4, 7=Trigger Only) ; - the AOUT channel to output velocity (1-8, 0=disabled) DEFAULT_TRKINFO MACRO ;; Name SR Pin MPort AChn db "BD ", 1, 1, 1, 0 ; Track 1 db "SD ", 1, 2, 1, 0 ; Track 2 db "LT/LC ", 1, 3, 1, 0 ; Track 3 db "MT/MC ", 1, 4, 1, 0 ; Track 4 db "HT/HC ", 1, 5, 1, 0 ; Track 5 db "CP ", 1, 6, 1, 0 ; Track 6 db "MA ", 1, 7, 1, 0 ; Track 7 db "RS/CL ", 4, 0, 1, 0 ; Track 8 db "CB ", 4, 1, 1, 0 ; Track 9 db "CY ", 4, 3, 1, 0 ; Track 10 db "OH ", 4, 4, 1, 0 ; Track 11 db "CH ", 4, 5, 1, 0 ; Track 12 db "Ext1 ", 0, 0, 1, 0 ; Track 13 db "Ext2 ", 0, 0, 1, 0 ; Track 14 db "Ext3 ", 0, 0, 1, 0 ; Track 15 db "Acc. ", 7, 7, 7, 0 ; Track 16 ENDM ; ; define the track which is used for global accent ; (0=disabled, 1-16: track number) #define DEFAULT_GLOBAL_ACCENT_TRK 16 Regards, Janis
  18. Some time ago found this link: Regards, Janis
  19. Very similar is MBHP_DINX2_V1 too. http://www.ucapps.de...hp_dinx2_v1.gif Its top view . For your MBHP_DINX1 you need built only left side part with 1 x 74HC165 chip. Blue and red lines are connections between component pins and supply: +5V and GND terminals. Crossing lines with the rounds on it are connected , too ! sorry for my not so clear english. Regards, Janis
  20. Hi, Gunars ! In digital schematics bypass caps 100nF are placed between Vdd and ground (Vss) of each chip as close as possible always . Adding some polarised capacitors are recomended too. http://en.wikipedia....pling_capacitor Using 100pF terminators for din and dout chains I understand as high frequency filters. Regards, Janis
  21. Thanks, Wilba ! Left side 3 x 8 diodes : SR#1 CATHODES rows from UPPER to LOWER D6, D4, D2 SR#2 ANODES from the LEFT to the RIGHT side D7-D0 Right side 3 x 8 diodes : SR#1 CATHODES rows from UPPER to LOWER D7, D5, D3 SR#2 ANODES from the LEFT to the RIGHT side D0-D7 Regards, Janis
  22. Thank you Wilba for a fast answer! Regards, Janis
  23. Hi I have interest to build Wilba's sammichSID on standard MB project boards. Do not find sammichSID CS DOUT map circuit . SR# 1 6 x CATHODES , SR# 2 8 x ANODES I think. Thanks in advance. Janis
  24. As i understand, the more reliable construction is when pots are wired with the wires not on the pcb's. When you need replace damaged components it's easiest way for service works. Regards, Janis
  25. I could be wrong. But HC49S characterizes only low profile package of quartz crystal and it is right "parallel cut" crystal. http://www.cresttech...u/pdf/HC49S.pdf Janis
