For this I'd recommend another approach: Usage of several voltage reference sources (e.g. TL431) with adjustable output voltages. For adjustment (e.g. 1.00V, 2.00V ...) I'd recommend 25-turn precision trimming potentiometers. This avoids the need of 0.1% resistors with the right

hello moogyfoogy, i have to agree with florian. i too have the system100. it has a different sound from the AS and the Doepfer. but, you can make a million sounds more with the doepfer modular (and the AS modular, btw)! and with the right programming and specific modules you can

I would like a module with some precision constants available, perhaps a 4HP module with CV Source outputs for precise whole numbers like -3,-2,-1,1,2,3,4,5VDC. I'm guessing this is a very simple module to make, like some of the other recent suggestions. I think it would be usefu

I'm about to purchase my first modular system and am debating between Doepfer and Analogue Systems. Does anyone know which system,if either,would sound close to a Roland System 100 ? Thanks, Terry.

An precision adder is from the technical point of view no problem (nothing but the CV mixer on the DIY page but without attenuators and precision 0.1% resistors and high quality OpAmps). If there are sufficient inquiries we could develop such a module. How about a poll ? Best wis
2005-12-19 by Dieter Doepfer
The fuse values are recommended by the manufacturer of the transformer and we took them over without changes. We test all A-100 systems and frames that are manufactured in our company with the full load (i.e. 650mA for the old version of the power supply and 1200 mA for the PSU2)

hello dieter, with the right amount of jacks this module would close a real gap in the a100 module range. what i always wanted is a buffered version of an a180 and a precision adder could be used that way too, if it had enough jacks. how about three inputs, four buffered outputs

2005-12-17 by okiikahuna
Ingo, I think that this is an absolute necessity. It could also serve as a buffer, since the CV output of some modules, like the midi to CV module, drops if fed into too many oscilators and filters and such. There are not a lot of good alternatives out there: Analogue Solutions m

hello, don't think it's shorting anywhere inside the suitcase (it's got composite-plastic walls and aluminum railings which shouldn't affect even when touched), but i'll check anyway. it seems to happen only when i'm taking it somewhere (that's why i asked about moisture buildup)

2005-12-17 by Ben Vehorn
I'm not sure if this is the problem you are having, but some Doepfer modules have PC boards *very* close to the edge of the module and it's possible that the power traces are shorting out against your case. This happened to me when I tried to install a certain Doepfer module (eit
2005-12-17 by tkrakowiak

2005-12-17 by ilanode
Oooops, I was *totally* wrong about the mA. Sorry! Just checked the Doepfer HP -> FAQ where you find the following values: Old PSU 650mA = 125mA at 230V mains voltage (250mA at 115V) PSU 1200mA = 250mA at 230V (500mA at 115V). Fuse type: time lag (slow blow), "traege" in German.

Isn't it you who bridges blown fuses with conducting candy papers? Glad to hear that you've changed your approch! :) Don't know how much current your modules draw but since the old PSU supplies 650mA and the PSU2 1200mA you should get fuses which correspond to the PSU: 0.65A or 1

Why not use a multiple plus an Analogue Solutions ATT4 passive attenuators module? Just take your input and pull 4 outs from it using the multiple, then put each through a separate attenuator in the ATT4. http://www.users.globalnet.co.uk/~concuss/concussor/att4.htm Seems as if it

Hello David, some of the techheads could explain the how-to-do-it better then me: Basically one can start with the A129/3 (Vocoder SL). Wether simply connecting the switch contacts of the jacks does job, or if not you have to replace the pcb mounted jacks with non pcb mounted one

I hate to say it, but if no one has a schematic, then you will have to "reverse engineer" the circuit to find out how it works. The Doepfer modules that I've seen are single sided PCBs, so it's definitely easier to do than if they were double sided. Romeo Quoting danv_83 : > Inte
