Being not that familiar with midi sucks but can anyone help?  I read 
the manual and followed everything but for some reason, connecting any 
midi keyboard and pushing the learn button for the lowest note, I 
cannot play any other tones except the base note or maybe its the 
reference note.  What am I doing wrong?  Thanks in advance people.

I need some more details. Does the MS-404 trigger correctly via Midi but the
pitch does not change ? In this case I assume that something is wrong with
the pitch CV between the Midi interface and the VCO (maybe a defective
digital-to-analog converter). Did the MS-404 work before or did you buy it
second hand ?

If it helps: the MS-404 service manual is available on our website (>
MANUALS > user's guides of older devices > MS-404).

Best wishes

I remember that I had the same problem a while ago.

I read again in details the MS-404 manual two or three times and 
finally found that I was wrong when sending program changes to the MS-
404.

If this can help you to solve this problem, try to send these PRG 
changes to your MS-404 :

Key Assign Mode 'Highest Note' : PRG 15
Key Assign Mode 'Last Note' : PRG 16
Key Assign Mode 'reference note' : PRG 17
Key Assign Mode 'Stack Note' : PRG 18

Thanks Deiter for responding first of all.  Yes, the ms404 does 
respond to midi and I am able to select the lowest note.  I'm hoping 
that it isn't something that needs servicing.  I did get it second 
hand and the person I got it from didn't say anything about it being 
defective.  Do you know of any service centers in the San Francisco 
bay area that services your equipment?  Thanks in advance.

Hey Dimitri-
Thanks for your input.  As I said, I'm not that versed in midi 
however I have been able to put it in learn mode and at least make 
lowest note.  Other than that I don't know how to do what you are 
suggesting above i.e. Key Assign Mode, etc..  I do appreciate your 
help.  If there is anything else you can think of I'd like to hear.  
p.s. I'm using either a Yamaha AN1X or a Nordlead 2 if that helps.
regards, Mark

Hi Mark,

May be you should ask at Analogue Haven (although they are near LA). Or 
check the archives of analogueheaven (sic! with 
"e"):http://search.retrosynth.com/ah/

I'd recommed to look at the MCV4 manual (no typing error, I really mean
"MCV4"). The MCV4 manual describes the different key assign modes in detail
and how they are programmed via Midi program change messages while the
MS-404/MCV4 is in the learn mode.

thank you very, very much Florian.  right under my nose here.  also 
have a moog prodigy i need looked at.  thanks!!!

Hello there,
my first time here , and i discover there are other people with same problem,
Fortunately i resolved it following the tricks gived me by mail from mr doepfer.
I sent a message of program change  as it write on the user's manual, followed by a 
message of note on 
the machine now works at his best.

peace

Hi,


I am running in the same problem as Mark Kono did in June:
My MS-404 worked fine with MIDI; I used it as MIDI-Slave of a MIDI 
keyboard or with an Alesis MMT-8 as Sequencer. Now  I connected the 
MS-404 to Logic Pro and it shows the same behaviour as Mark described:

MIDI-Note on produces a positive Gate and a Note CV of 0 Volt.
I can change the reference note in MIDI-Learn Mode, but the Learn Mode 
appearently does not react on Program changes, because I cannot change 
e.g. the trigger polarity (prgchng #7 or #8).

I usually have the EPROM with revision 1.05, but also tried Revision 1.03.

I tried the reset described in the Manual of the MCV4(as recommended 
from Dieter): press and hold learn butt, switch on and hold until learn 
LED starts blinking; after that switch off an on again. But it did not 
work: after switching on with pressed Learn-button the Learn-LED never 
started blinking.

So how can I make the MS-404 react on MIDI again?

Florian

PS: The MS-404 works fine under control of an external CV in. There is 
no voltage change happening already at the output of the D/A-converter. 
Hardware defect in the D/A is possible, but I don't assume so, because 
the Gate is working.

Hi,

I could solve the problem by an ugly trick (this is a "don't do this at 
home" description): First I removed the EPROM and switched the MS-404 on 
and after some seconds switched it off again. I replugged the EPROM and 
tried the MS-4040, but the action hadn't changed anything.
Then I removed the EPROM again, switched the MS-404 on and pressed my 
fingers on the soldering side of the pcb on the pins of the processor. 
The fingers seem to act like a pulldown resistor. At least the internal 
RAM of the processor seems to have been resetted by this action. Now the 
learn mode accepted Program changes again and I could set the assignmode 
to last note again.

Nevertheless it seems, that the processor of the MIDI-interface MS-404 
reacted wrong on some MIDI messages from Logic while the interface was 
in the bootup phase.

Regards, Florian

Florian,

very strange. I have no idea why this solved the problem. The contents of
the internal RAM should have no effect on the function as it is filled with
certain values during power on. The reset during power on causes the
software to start at a certain position (reset position) and the contents of
the RAM should not matter. I'll send a copy to Christian. Maybe he has an
idea for this strange behaviour.
