As there are no separate outputs for the different wave shapes, you may consider (at least) three oscillators (1004). For instance : one for the main audio source, one for an audio-rate modulation source (to do FM or ring modulation) or for a second audio source (to have detuned oscillators), and the third one for slow-rate modulations (thus a LFO). The two other modules to consider are : - the 1005 ring modulator / vca. It can do quite a number of utility functions : constant voltage generator, inverter, VCA for control signals (the 1006 cannot do that : it is for audio signals only) ; - a second 1006, or a second 1050. There you have a choice : for stereo applications, the output module(s) of the system will probably be a 1050 or two 1006s. If you are using a 1050 as the output module, you may need a second one to mix/sequence other things, such as control signals or clock signals (the 1027, for instance, has many clock outputs). Since all the modules have several modulations input, you can do without mixer, but if you want to replicate the modulation matrix of the original 2500 (where you could mix any number of signals into any input of any module), the 1050 is the best solution (you can mix two groups of 4 signals, or one group of 8 signals with it).

@@lnefpd Fantastic, thanks for the detailed info!

I love mine. I was playing on the same setup yesterday.

I have never played a real 2500. I wanted a big analog system, and i choose this one, for three reasons (which have become more and more obvious with time) : 1) it looks beautiful (because of the colors, and also because the modules are all designed in the same way), 2) the modules are big (which is also a drawback : the cabinet is full with 'only' 30 modules), so when there is a lot of cables, you still can see quite well what you are doing, 3) there is a kind of minimalism in it which i find inspiring (there are only 9 different modules : that is completely different to a Doepfer system, for instance, where there is much more modules). As for the size, the idea is to experiment what you could *not* do with a real 2500, even the largest setups. For instance experimenting with an absurd number of oscillators, or filters, or sequencers, etc.. (The affordable version of Behringer make the creation of really large setups possible, if you have a little money to spare.) For the sound : it would be quite difficult to compare with a real one, because the components of the few remaining instruments have aged. Furthermore, i'm almost all the time using effects, such as reverb or delay pedals, so the sound is altered, in any case.

@@lnefpd I hear ya!! I was lucky enough to spend a lot of time with a 2500 during college so that is my main motivation for looking into clones but I def see where you are coming from with this. Its definitely beautiful and sounds great, glad you are happy with it.

You can assemble them together : www.modularsquare.com/shop/doepfer/connecteur-droit-a-100mvg-2/ (there are bolt holes at the back of the cabinet for this). It's solid, but it's quite expansive for what it is, i must admit.

The cabinets are two Doepfer «low cost » Monster cases : doepfer.de/a100p_e.htm#A100LMS9 It's 9U (actually : 3 rows of 3U « eurorack » format) by 168 HP. The modules of this series are 16-hp wide, except the mixer which is 24-hp, so you can put 1 mixer + 9 modules per row (with one exception : the noise generator is 14-hp wide).

Yes

There are two VCA modules in the 2500 series : the 1006 "FiltAmp" (for audio signals only, and it is also a filter) and the 1005 "ModAmp" (for both audio and control signals, and it is also a ring modulator). So if you want to modulate the amount of a modulation, the 1005 ModAmp is the right module. Example : you want to modulate something with an enveloppe, but with a random amount of that enveloppe. To do this, you send the ADSR output into the ModAmp "A" input, and the output of, say, a 1036 S&H, into the ModAmp "CV" input. The output of the ModAmp will be the enveloppe multiplied by a random voltage. The ModAmp is the module i use the most, because it can do quite a lot of useful things (offset generator, inverter, two-stage VCA...). But of course if you are using modules of other brands, these functions can achieved with smaller modules : here i'm using only 2500 modules « as an exercise ».

@@lnefpd thank you for the reply. I do have a some cases filled with plenty of utilities and plenty of vcas, however, as an exercise I enjoy piecing systems together (like the System 100 or Intellijel) and forcing myself to use only those modules. The 2500 series seems to have a very unique experience and looks fun to explore.

Thanks !

No quantizer. So you have to spend a little time to « tune » the sequencers when you want a precise series of notes, but anyway, quantization or not, once you add exponential FM the notes cannot stay in tune.

Just two minutes after the publication : pretty good reaction time. Thanks for watching !

@@lnefpd I'm from Russia, I was looking for a guitar pedal and found you! Where are you from?

@@lnefpd I went to your channel, I was very surprised that the video was released 40 seconds ago, gorgeous ambient

Of course not ! In the sense that you don't need all that to make music. Serious answer : the real point is how long will these cheap modules last. If they are still working in 10 or 20 years, then, yes, it will be worth the money.

@@lnefpd that’s true. i guess it is a test of time. these just look so dang cool haha :)
