Hi everyone. I need to purchase a MIDI - CV converter and would like to use with my A-100 and MAX/ msp, but also with a keyboard. I'm looking for a very versatile unit and so the mcv 24 looks nice with all those outputs. The Doepfer mcv 24 seems like the most powerful/versatile o

Dear Dieter, Thanks, found the pot (p8), and am playing around to find setting(s) I like. It's an awesome filter by the way. Cheers Martin > > Martin, > > there is a trimming potentiometer on the A-108 board that is used to adjust > the resonance so that self-oscillation just app

Hi, as far as I remember the ribbon controller of the Yamaha CS-80 works that way, that it takes the position, where you touch the ribbon the first time, as the center (=0 Volt) and if you move then your finger it produces voltages which are an offset to this center. Now I am loo

This FAQ has been written by Christian Assall as he owns an MS20. He has also written the software of the A-190 (and MCV4, MCV24 ...). As far as I remember you have to adjust a control at the MS20 to obtain the correct scale for the 1V/octave pitch sent by the A-190. If you still
2006-06-01 by Dieter Doepfer
Martin, there is a trimming potentiometer on the A-108 board that is used to adjust the resonance so that self-oscillation just appears at the full clockwise position of the resonance control. This trimming potentiometer is adjusted for the default feedback (48dB output). If anot

the ms20 uses a negative trig , cant remember if the a190 can output this but there is a very simple circuit to transform positive trigs to negative ones ,, or gnd-trigs that is, on the other hand the note cv can be used with V/oct , actually better tracking of lower frequencies

OK actually I got the gate problem fixed, and I got the program changes fixed (setting on the midi keyboard was the problem - I just needed them to change parameters on the A190) - so it is working pretty good new except the pitch CV is way off. Now doepfers website gives this ex

I am tring to control a Korg MS20 from a midi keyboard by using the A190. Its working ok but I have a few questions. if I play a note on the midi keyboard there is silence until I let my finger off and then the note sounds. I figure this is some sort of reverse polarity or revers
2006-05-31 by marrtin606
Dear Ingo, Bakis, you're of course right I don't need the feedback to get some form of resonance - but the point was to understand why i couldn;t get resonance using only 4 poles. I'm pretty sure the feedback is internally patched to the 48db - apart from the manual and schematic

Dear members, as many customers who ordered the A-188-1 module with 128 stages (MN3006) did not want to wait for the revised module version we developed a small adapter board (similar to those for the 4096 stages BBDs). Now we are able to offer even the first version of the A-188

2006-05-31 by Bakis Sirros
Ingo is right on that. you can get resonance sounds and self-oscillation on the a108 without patching the res feedback input(because, i think, by default the res feedback input is internaly patched to the 24db filter output). if you want, of course, you can patch the res input wi

I don't own a A108 but I'm quite sure for an "ordinary 24db filter" you will not use the Feedback In. Audio In and Audio Out plus the CV Ins that's it. The Feedback In is a special feature for "non- ordinary" stuff. Regards, Ingo --- In Doepfer_a100@yahoogroups.com, "marrtin606"

To increase the input gain R15 (22k) has to be lowered (e.g. 10k). R15 is located just behind the potentiometer for the audio input level. More details on the A-100 DIY page of our website. Best wishes Dieter Doepfer > -----Ursprüngliche Nachricht----- > Von: Doepfer_a100@yahoogr

It seems that there's something wrong with the exponential converter. Please send the module for repair/service to your distributor. If you are a bit experienced with electronics you could try to find the problem yourself (maybe only a solder jumper is missing). In this case plea

Hi James, what is so difficult not to do it by yourself? You have to develope a standard how to use Kontakt with MIDI for yourself, e.g. if you're using a filter module, you have always to choose the same MIDI-CC to control cutoff, resonance and so on! Once done it will always do

If nothing is connected to In 1 the pot will simply add V to the output of the mixer. The V range goes from 0V (fully ccw) up to 5 V (fully cw). E.g. your CV for a VCA is an LFO since it's range goes from -2,5 to +2,5 you will only hear the audio signal if the CV is above 0 V; wh
2006-05-23 by Bakis Sirros
hello richard, if you do not connect anything on input 1, then the input1 knob acts as a cv /offset source. that means: it adds to the other 3 inputs an offset of 5 volts (or - to +5 volts, if the a138c is the case). so , then, the mixer outputs the sum of the 3 input signals(fro

thanks guys I don't quite get what a138 does. If I don't plug anything into the first input does that mean I can effectively control the output so it can't go over 5v or under 0v?? somehow my brain and the description in the pdf are not connecting. Richard ----- Original Message

let's assume that you use an a147 as lfo and an a138a linear mixer (the latest revision). the sinewave has a varying amplitude of -5/+5 volts. feed this sinewave into input 2 of the a138a and set the attenuator for input 2 to 12 o'clock position. this reduces the lfo amplitude to

2006-05-22 by Bakis Sirros
hello richard, the cheaper of the 3 solutions( a129/3, a138c, a167) is the a138c polarizing mixer. it gives you a -5 to +5 volts offset source at input1 and you still have 3 inputs to attenuate doepfer signals and mix them(and invert them if you like too!) before sending them to
