as a total newbie in analog modular synthesis I am looking for
information concerning the compatibility of different systems.
as I know there are 5 and 6HE modules,
there are also differences in power distritbution...

with systems are compatible ?
maybe you can help me with a good link ?

I am especially thinking of some Motm or DotCom modules.
there are also interesting new german modules http://www.curetronic.de/curetronic/index-start.shtml

what do you think of http://www.modcan.com/page2.html modules ?

rob





edit. just found http://www.modularsynth.com/chart.html
but : do you have recommendations / tips concerning the
combination of different systems ?

actually,
I have just decided to start a nice little modular
based on Motm and DotCom modules.

Cool

That chart is excellent. I would just make sure that all of the modules you choose have the same standard for CV and Gate/Trigger. 1V/Octave is pretty standard for the frequency CVs, but make sure the Gate/Triggers are the same. You can always convert from one kind of jack to another, but of course it is easier if you pick a standard for your modular rig and stick to it. I prefer 1/4" for audio - I haven't had much luck with minis. For controls, I like 1/4" or Bananas. All a matter of personal preference, of course.

Here is another, more extensive, comparison chart: http://www.synthesizers.com/formfactors.html.

Actually I was thinking. Can one make a blanket statement that that in all modern (meaning since the 1990s) CV based equipment the CV & gate signals are compatible (and nothing insists on a separate trig signal anymore)?

I've got the feeling you almost can, though I'm sure some obscure combo out there that's an exception.

On the other hand if you are into 70s gear then the "standards" are far from standard.

Not Buchla ... maybe not sure, but ... he does things ... differently ... ;!)

Even the Buchla stuff will work with the Moog style stuff to some extent. Buchla traditionally hasn't been intereted in conventional note-based music, so accurate oscillator and filter tracking hasn't been his focus. If you want to do a Switched On Bach type thing, some synths like the Buchla aren't going to be all that well suited. Still, they do play together.

Well.... actually... because of the type of 'open-ended' sequencer, the Moog 960, and Synthesizers.com Q960 do like the difference between a 'gate' ( a sustained pulse) and a 'trigger' (a short pulse similar to a sawtooth). With running analog step sequencers, side-by-side gate signals aren't usually seen as separate signals, but rather, one long signal. The trigger remedies this.

Initially, the dotcom Q960 was designed to work with gates, but very quickly, I showed Roger that it was nearly mandatory to be able to use triggers when it was desirable, so he came up with a modification to easily bring out the triggers. The triggers allow EG's and other modules which may need to see individual events or steps on the sequencer, actually see each step.

If you have another brand of step sequencer.... give this a try yourself, and see what happens. You need to be able to use 'individual' gates from each individual stage... NOT the master gate output. Each stage having it's own individual gate/trigger input and output is what allows the patching magic, which made the original Moog 960/962 so famous. Some newer sequencers may provide individual outputs... but you also need the trigger inputs to make full use of this giant among analog stepping sequencers.

There seems to be some difference in waveform levels between manufactourers (Or atleast from modcan) Or am i reading the information wrong ??

From Modcan : " Waveform Voltages: 0- 5V and +/- 2.5V peak-peak"

From Doepfer " Audio Signals are produced by the sound source Modules (such as VCO or NOISE), and lie in the range from -5 V to +5 V (10 VSS)"

From Blacet : "Standard +/-5V Waveform Levels"

From Motm : "Audio levels of 10V pk-pk"

But this only results in a weaker audiosignal, right ??
