The matter is simple: a modular synthesizer with all of the necessities can cost us a lot of money; and in my particular case, the import of components to my country (Chile) is very expensive, which has led me to stop the construction of some more complex modules.
Luckily there is the virtual alternative, which is not the same as twisting a real knob but allows us infinite exploration in the world of modular sound.
The VCV Rack software is free (open source) and includes many modules to download. Others can be purchased from its creators (the price is very low) and there are also donations to support a vast library of constantly growing modules. Best of all, it is available for Mac, Windows and Linux, only in 64-bit architecture.
I'm using it on a 64-bit HP laptop, 2.8 GHz processor and 6 gigabytes of RAM running Linux Ubuntu 18.04 and it works wonders.
There is also a web page with tutorials and patches that you can download to begin to understand the workflow of VCV Rack, which is not as complicated as it seems. Plus if we make any errors we will not pay with the destruction of an electronic component; it will simply indicate to us that there it is not possible to connect one module with another.
I think it is a good alternative to know in depth the modular synthesis and to be encouraged in the future to acquire a physical device.
