  We report on the controlled creation of multiple soliton complexes of the
dark-bright type in one-dimensional two-component, three-component and spinor
Bose-Einstein condensates. The formation of these states is based on the
so-called matter wave interference of separated condensate fragments. In all
three cases a systematic numerical study is carried out upon considering
different variations of each systems' parameters both in the absence and in the
presence of a harmonic trap. It is found that the judicious selection of the
initial separation or the chemical potential of the participating components
can be utilized to tailor the number of nucleated states. The latter increases
as the former parameters are increased. Similarities and differences of the
distinct models considered herein are showcased while the robustness of the
emerging states is illustrated via the numerical experiments demonstrating
their long time propagation. Importantly, for the spinorial system, we unravel
the existence of beating dark soliton arrays that are formed due to the
spin-mixing dynamics. These states persist in the presence of a parabolic trap,
often relevant for associated experimental realizations.
