thank you stiiiiiiive!

hope someone´s gonna jump in

hmm, any murf-owners here?

Hallo,

i have an issue with a MF-105m which i got last week.. not sure if the LFO-behaviour is normal or not.
In Pattern nr.1 (stativ Filter) the LFO is about 9 seconds per one cycle, so very slow.
If i plug a cable into the LFO-CV input and unplug it the LFO is up to approx. 1 second per cycle ...

>Perhaps your internal keyboard based V/Oct creation is not adjusted to exact 1V/Oct,
ah.. thanks for the hint! this could be the problem as well actually.
someone knows how to check if the internal keyboard sends the correct voltage?
not sure, if i would check it these days, but as soon as i´d ...

Hallo,

the tracking of my Minimoog Model D when played over the internal keyboard is quite good.
but when i want to control it from an external keyboard the tracking isn´t, the spread is too big..
higher notes are too high and so i have to attenuate the signal first.
i couldn´t find anything in the ...

do i have to connect the minus-pole of the battery somewhere?

>Sorry typo... it's a 1n4148 diode you need... :D
thanks!

>The ground will be connected via the Jack lead...!
the ground/ring-solder points of the input/outpug-plugs then i guess
(not being a native english speaker some terms are less clear from time to time)

i´ll do it that way.. external box!

thank you very much tom!
in connection with the schematic it´s now totally understandable!
yes finding out the transistors legs/diode polarisation is no problem,
also i looked up the symbols now to be able to comprehend the schematic :idea:

can i use the micromoogs output sockets for wiring to ...

thanks for your help, but the schematic is not really readable very well,
apart from my little technical understanding i can´t really identify every letter.

>You'll end up with a synth that needs much more work putting right any problems that you will inevitably cause... :(
i won´t do it unless ...

thank you!
unfortunately the schematic is not very understandable for me (and my small skills) next to the writing.
if anyone has done this with his micromoog and has a better schematic, this would be really great.
question is also if/where i can directly tap voltage from the micromoog itself

hej tom,

yes, as i already noticed .. "needs additional voltage"
the question is how it can be done.

okay.. regarding the s-trig-mod not working.. seems to be more complicated and needs additional voltage..
if someone knows how to turn the s-trig output into a gate output, please talk

in addition to problem number 2) i wanted to explain a little better what i tried converting s-trig out to gate out..

inside of the micromoog i solder the "tip"-contact of the male s-trig out plug directly to "C" of the specified transistor.
transistors "E"-leg gets connected with s-trigs ground ...

Is the micromoog hrtz or volts though? Not all moogs are the same.

thanks for questioning me :) i found out that the micromoog is actually quite an outsider having a 0,95V/Octave characteristic! :shock:
i followed the instructions of a german forum connecting a 10k linear potentiometer in series ...

it´s a normal 1v/oct signal working well with my minimoog, so it can´t be that. thanks
