From what I understand, Analogue Solutions modules are doepfer-style width
modules, so can be used in a row with other doepfer modules with no gaps.

But Analogue Systems modules use a different width standard for the
modules, so while Analogue Solutions (and Doepfer) modules can screw into
an ASYS rack just fine (with the appropriate adapter power cables) if you
want to mix a row between ASYS and ASOL/Doepfer modules there will be
gaps. As long as you keep the row homogenous, no gaps.
