Is modular synth hard?
Learning how to “patch” modular synths isn't difficult – once you grasp how they work on the inside, and know what each module is doing to the signal flowing through it. Fortuantely, this knowledge can be learned in just a few hours, and will cost you less than most modules.
How are modular synths powered?
Each module will have a ribbon cable attached to it, which will then be typically connected to a power distribution board, known as a 'bus board'. ... Essentially, in basic terms, this power source takes electricity from your mains supply and converts it to a form that is then safely distributed to your modules.
