Hi, The some Eagle files from the eight-oh-eight.org forum, i think. Regards, Janis 808_production_Individual_Files.rar

Hi, I have some changes in my MBSID a custom build CS part - have an additional button for ARPegio ON/OFF function DIN_ENTRY CS_MENU_BUTTON_Arp, 16+1, 4 ; **new** Arp button (Janis custom CS) It's workinkg fine . For better viewing the state - ARP ON/OFF I prefer to switch accordingly ON/OFF a led. I think is enough to make changes in two files, maybe: 1. cs_menu_leds.inc .... bsf TMP...,... 2. setup_mb6582.asm DOUT_ENTRY TMP...,..., 16+...,... ;; SR#, Pin# numbers are custom,have spare places for leds May be some of programmers can help to define an ARP led. Regards, Janis

Another midibox sorce files compiled without mistakes. I have a custom MBsid CS part. Regards, Janis

Hi, In the Midibox64 by default you are able to switch on / off a led #1 with a GP button #1, etc. I tested this way up to the 16 GP buttons with the 16 appropriate leds. http://www.ucapps.de/mbhp/mbhp_doutx4_32leds.pdf http://www.ucapps.de/mbhp/mbhp_dinx4_32buttons.pdf Regards, Janis

Hi, You need to upload the latest mios_v1_9g http://ucapps.de/mios/mios_v1_9g.zip of course, for the MB64 application - setup_midibox64.hex Regards, Janis

Hi Roger, The Core pcb's and the pic controllers successfully arrived. Many thanks ! Regards, Janis

Hi mikee, http://ucapps.de/pic16f_firmwares.html Maybe I am wrong. The schematic of the old pic16 based Core module is almost the same, only the MBHP_CORE module has to be stuffed with a PIC16F877 and a 20 MHz crystal. Regards, Janis

Hi, I do not know about your pcb sources. - I remember, on the Core board from Mike, I soldered 2 additional isolated wires for communication purposes, an additional cable between the CLK input of the SID and Core::J7:SO/PIC Pin #17 at least. http://ucapps.de/mbhp/mbhp_core_v3.gif - You need to recheck the connection cable between the Core module and the Sid module, too http://ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf Regards, Janis Reinholds

Arrived. Joonas, Thank you ! Best Regards, Janis

Hi, I understood the screw position changes did not take it job. may be it not working properly.Not a good contact inside it or somesing else. Is P1 50K , marked 503 and is P2 10K, marked 103 ? you need to regulate the both of screws for better result. Regards, Janis

You can also to measure the trimmers resistance changes with the multimeter in the various screw possitions without applied voltage. Regards, Janis

Hi, You can listen to a square waveform and some various waveforms here under an VCO article part: http://www.musicfrom...PW=1356&VPH=533 Regards, Janis

Hi, From the Wiki http://www.midibox.org/dokuwiki/lib/exe/fetch.php?hash=6e29d6&media=http%3A%2F%2Fwww.mb6582.org%2FsammichSID%2FsammichSID_Build_Guide_v1_0.zip Look at page 17, from here you can find some info about powering LCD backlight part. Regards, Janis

Hi, May be I am wrong. Could this be a problem with the some wire interconnections mistakes, shorts. If you are looking from the OPL3 board side, connector J2 2 address control wires to the Core module RB4 - RB7 port . from this diagram http://ucapps.de/mbhp/mbhp_opl3_interconnections.pdf Regards, Janis

Hi, Welcome. Try to read in the Wiki pages for the some info about sammichSID. you will need to read the Midibox sidv2 User manual chapters, it's what you need. Regards, Janis

Hi, It's not the same: , but the additional resistor can do more stable the merger work. Regards, Janis

Hi, Are You meant to initialize to get the default patch ? From the Sid2 manual pages: the patch should be initialized to get a defined start. Press&Hold the SHIFT (formerly LINK) button and press the select button below "Ini" to get the default patch: Regards, Janis

Hi, only +9V output for the 8580 chip . But the 7809 linear regulator i.c. can do it from +12V output easily. Regards, Janis

Hi, The function tables are look identical both, too. The each inverter Output logic level is inverted versus to its Input logic level: H goes to L and L goes to H. Regards, Janis

Hi, Yes! all the four PIC18F4685s to be programmed with the IDs: 00, 01, 02, 03. An every engine has a unique ID. In the many Gallery pic's you can see that, too. Regards, Janis

Hi, here is another 4 inputs mixer http://www.next.gr/i...l074-l6661.html Regards, Janis

Hi, Are you could to measure 5 volt on the resistors network marked pins for the RN2 and RN4 parts? http://www.midibox.o...hSID_CS_PCB.pdf Regards, Janis

Hi, If you used MB64 setup connection diagramm looks like : http://www.ucapps.de...p/auaimbctg.pdf and asm setup file part looks like: ; Setup File of TK's MIDIbox64 ; ; Number of connected pots ; Allowed values: 1-64 #define DEFAULT_NUMBER_POTS 20 ; number of connected pots ; ; Multiplexers (AINX4 modules) connected? -> set this value to 1 ; No multiplexer connected= -> set this value to 0, allowed number of pots in this case: 1-8 #define DEFAULT_MUX_ENABLED 1 ; enable multiplexers ; Regards, Janis

Hi, A nice link. I do not recomended to connect the transformer two secondary windings in parallel. It can cause for more transformer heating ,than under normal usage conditions, no safe. Not every transformer manufacturer recomended do that way connections , the secondary windings are not so identical, I think. Regards, Janis

+1 I lost some time with those extra resistors in the slaves cores. My MB6582 board has 6N136 instead of 6N138 http://www.ucapps.de...136_variant.jpg Regards, Janis
