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

Hi,
I got a mistake to tried to compile unzipped MBsid source file without any changes in it before.
Another midibox sorce files compiled without mistakes.
I have a custom MBsid CS part.

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.

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.hexzipfile: midibox64_v2_4f.zip midibox64_v2_4f\setup_midibox64.hex <--- is this the right file to upload?.

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

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.

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

Arrived.
Joonas, Thank you !
Best Regards,

thnak you! :)
arfff my backlight screw doesn't work! :pinch:
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.

Janis

my backlight isn't bright enough...
You can also to measure the trimmers resistance changes with the multimeter in the various screw possitions without applied voltage.

Hi,
You can listen to a square waveform and some various waveforms here under an VCO article part:

Hi,
Look at page 17, from here you can find some info about powering LCD backlight part.

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

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.

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

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:

Hi,
That was very helpful, thanks! Seems like Meanwell RPT-60B is ideal for me, could even fit inside the synth (since it is 3 octaves long) so, no need for a case. Has transformer built-in, too, i just need to mount an IEC socket on the back panel and i'm good to go. What do you think? Am I missing something?
only +9V output for the 8580 chip . But the 7809 linear regulator i.c. can do it from +12V output easily.

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.

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.

Hi,
Are you could to measure 5 volt on the resistors network marked pins for the RN2 and RN4 parts?

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 ;

Can someone verify for me that if I wire the two secondary outputs in parallel, the voltage I get from it is still 12v and twice the current capacity?
That is, if I want a 12V secondary with centertap and 2 amp, I can use a 12v dual secondary xformer @ 1amp each output?
Thanks for the help.
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.

Janis

I don't recommend you install them until you're sure you need to.

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

MB808 from the begining, sources of info

Hi,
The some Eagle files from the eight-oh-eight.org forum, i think.
