Hi,

When you removed an old pin bridge you needed to clean all holes with a needle or a small size drill with a help of a soldering iron with a tin. Without a tin the hot soldering iron can easily to damage the traces on the pcboard.

[Sammich filter caps]

Hi,

For the filter part the preferred choice are capacitors with the low temperature coefficient

http://www.gqrp.com/na5n.pdf

the 6581are powered from +12VDC supply instead of +9VDC for the 6582.

[MIDIBox 808]

Hi filipe,

For the better understanding this project you need to "read deeper and deeper" another site articles

http://www.eight-oh-eight.org/

I think.

On the ucapps.de site there are components list for the Midi drum sequencer part only with the standard midibox platform pcboards. The complete MB808 you can see in the MIDIbox 808 Introduction Video has own pcboards.

It's possible the LEDs are connected as a matrix .

[MB 6582 PSU problem?]

Also, from playing it I've discovered a new issue. I'm using sidv2editor to play it currently as I don't have a control panel yet. When I play it I can't turn up the volume all the way, when I try to it gets really really quiet. It's happening on all of my 8580 sids, but it doesn't happen on my two 6581's... I'm super confused right now :S Any ideas?

It's normal, thats a known issue with the 6581' s .

from the wikipedia pages:

"...Due to imperfect manufacturing technologies of the time and poor separation between the analog and digital parts of the chip, the 6581's output (before the amplifier stage) was always slightly biased from the zero level...".

Janis

Hi,

May be I am wrong.

In the Mios32 based Midio128_v3 application is included toggle button option too :

[MB 6582 PSU problem?]

Hi Chris,

Which PSU option you are using?

For the PSU option B the V1 cannot share the same heatsink with V2 and V3 ! Or you can to isolate it from the heatsink.

[Broken menu button]

Hi,

In the MBsid_v2 user manual you can read about your sammichSID strange boot in ,

"the firmware saw "pressed MENU button :

" Updating Firmware to a new Version

Thats easy: just upload the new midibox_sid_v2 release to the master core with MIOS Studio.Once this firmware is booting, and the version number is displayed, press&hold the MENU button of your Control Surface to "clone" the new firmware to the slaves via CAN interface."

You can measure every resistor resistance for the 6 Pin Common Bus Resistor Networks. In the worst case not so hard to add an additional separate 10KOhm resistor, I think.

Janis

Hi,

From the wiki pages:

http://www.midibox.o...hSID_CS_PCB.pdf

May be you need to check the CS board for shorts with your multimeter and visualy.

[My SID won't turn on]

Hi,

May be I am wrong.

I understood , there are the memory chips addressing mistake:

http://www.ucapps.de...i_bankstick.pdf

When multiple EEPROMs are put on the same "chain", pins 4-8 will be connected together (like you have in this picture)... but E0/E1/E2 must be different, they give that IC it's "ID". It's simplified a bit... you would connect up the 5V and ground pins also... this means you can join many pins of one IC together and then just connect each IC to a common wire.

You can remove any of the ICs in this schematic.... ie. you can have just two, one with ID=0 and one with ID=7 (for MB-SID this is good, ID=7 is used for the "ensemble" storage, ID=0 to ID=6 is for patches).

Janis

[Pots not working properly]

Hi,

- May be you can recheck the multiplexers addressing bus:

Interface to J6 of the core module. These are the address pins of the multiplexers which allow the MIDIbox to select one of eigth inputs, the appr. signal will be routed to the output of the 4051. Connection matrix:

AINX4 J5:A -> CORE J6:RC

AINX4 J5:B -> CORE J6:SC

AINX4 J5:C -> CORE J6:SI

http://ucapps.de/mbhp/auaimbctg.pdf

- If you have the selfmaded ain module part, may be some wire, trace is omitted or not right connected

[Pots not working properly]

Hi,

Are your 24 pots defined in the setup_midibox64.asm file?

by default there are 64 pots :

; Number of connected pots

; Allowed values: 1-64

#define DEFAULT_NUMBER_POTS 64 ; number of connected pots

May be I am wrong.

[Conductor resistance ( Leiterwiderstand )]

Specific electrical resistance, electrical conductivity, Conductor resistance

The example section specifies the resistance of a 100 meter long copper cable 1, 5 mm²

100m , 1,5mm², Kupfer bei 20°C = 1,19 Ω

100m, 1,5 mm², Copper at 20ºc = 1,19 Ω

I HOPE IT HELPS TO UNDERSTAND THE PROBLEM !

I hoffe das es hilft das Problem zu verstehen !

Hi,

For the midiboxes inside wiring the preferably is using the ribbon cable which are ( from wikipedia ) :

..The wire is usually stranded copper wire, usually either 0.32, 0.20, or 0.13 mm² (22, 24, or 26 AWG)...

The 10 m ribbon cable single wire has the similar resistance ~ 1,19Ω.

[Midibox SID all in one keyboard/synth]

Hi,

I do not know many things, sorry.

I did some more reading for myself, too:

especialy #4

There are the some parameters for Arp controling in the Parameter Chart of MIDIbox SID V2 .

Thorsten can give the best advice for you, I think.

[Midibox SID all in one keyboard/synth]

Hi,

It is not difficult to add in this code string

DIN_ENTRY CS_MENU_BUTTON_Arp, 0, 0 ; enables/disables the arpeggiator of *all* oscillators

the right SR# and Pin# instead of ,0,0 .

The each button , encoder has own physical place in a shift register chain and it are need to be documented in the setup file.

after your changes are saved the next step is:

[Midibox SID all in one keyboard/synth]

So here is a mock up of the synth. I've added buttons for the arpeggiator. Is it easy or difficult to add that option to the hardware? I would certainly like to have an arp at my fingertips. I wonder if I've laid it out properly.

Hi,

Looks cool design!

The setup_6581.asm and setup_8580.asm files have entries for Arp ON/OFF function already. Only you need to enter the right SR# and Pin# for your own setup and to make the new *.hex file.

;; new for MBSID V2 (additional ***optional*** buttons)

;; don't worry, you still have full access to all functions w/o these buttons!

;; note that you could also re-arrange the pin assignments if required (e.g. if you don't like a certain button function)

DIN_ENTRY CS_MENU_BUTTON_M_Vol, 9, 5 ; matrix: button below M_Filter

DIN_ENTRY CS_MENU_BUTTON_Play, 9, 6 ; direct access to play function

DIN_ENTRY CS_MENU_BUTTON_SID_LR, 9, 7 ; direct access to L/R toggling

DIN_ENTRY CS_MENU_BUTTON_M_Mode, 10, 0 ; direct access to meter on/off function

DIN_ENTRY CS_MENU_BUTTON_Fil_ExtIn, 10, 1 ; direct access to Filter ExtIn Flag

DIN_ENTRY CS_MENU_BUTTON_Sync, 10, 2 ; jumps to ENS->CLK menu

DIN_ENTRY CS_MENU_BUTTON_Arp, 0, 0 ; enables/disables the arpeggiator of *all* oscillators

DIN_ENTRY CS_MENU_BUTTON_Knob, 0, 0 ; changes to knob menu

I did not find entry for the Arp ON/OFF led.

I have an interest to add the Arp led for my design, too.

[mb_6582 Power Supply]

[... And since I'm here : I received a 1st version C64 power supply and +5v is on pin 4 instead of being on 5... In fact, the plug only has four pins coming out, unlike my other "newer" C64 PSU that has all 7 pins (even though some aren't used). Can I bridge pins 4 and 5 inside my Midibox Sid without making a mess the day I plug my "newer" C64 PSU to the midibox ?]

You can bridge pins 4 and 5 inside your MB Sid
