using 12v and 15v in the same time..

[differance]

I am a complete novice ....
I would like to begin to build the modules but their size is to big for me so I will try to push pcb in to the Eurorack. it is possible?

2nd question:can i use simultaneously on the same rack module powered on 12v and 15v?
can i, for example, have two rows of modules one 12v and other 15v and run the audio signal from the VCO 15v to the VCF 12v? (or CV signal from 12v to 15v modules?)

I hope that my questions are not stupid...:/
I plan to buy a MFB nanozwerg and microzwerg and I would like to use them with the modular system.

thx

Welcome difference,

Your questions are good , they are questions so they are welcome.

First question, it depends of the size of the PCB and how you place it behind the panel, parallel, perpendicular... so also the depth of the case where the module will fit.
Second question, Yes, modules running at +/-12V can be connected with modules runing at +/-15V.

I can't say more or better than Sound already said.

Size : it depends on how you arrange the module behind the panel, I can tell you that many guys out there have built yusynth modules and incorporated in a Eurorack format (check the galleries at my site).

12/15: Yes this is no problem at all.

Thank you for yours fast response and understanding of my ignorance;).
In conclusion: modules and 12 v 15v may act in the same rack together. I'll only need two power supplies. yes?

Yes, Actually you could derive +/-12V from a power supply of +/-15V but I think it will be more easy for you two power supplies.
