interconnection between synth modules

[prof. Antonio Guerrieri]

Hi,
some one can suggest me the right way to connect modules of the same
analogue synthesizer system?
For CVs, it is OK a single cable?
For Audio interconnection, a coaxial shielded cable is OK? do you suggest
some particular impedance values? and, more important, to lower the overall
noise and/or to avoid ground loops, it is better to use single or twisted
pair shielded cables? do you suggest to grounding on both ends or just from
the output module?

Many thanks,

prof. Antonio Guerrieri
