Totally different...the A-110-6 is an analog VCO/LFO with the appropriate circuitry for TZFM and quadrature outputs, while the Plaits is a microprocessor-based digital oscillator with several very useful synthesis methods. While it might seem that that might not be a "proper match", the fact is that the A-110-6 is one of the analog VCOs that has the timbral complexity potential to hold its own against the Plaits when in use as a VCO, and has ample quadrature-phased waveform outputs for LFO use that can make the Plaits go morphing-bonkers when using the A-110-6 in that mode.
Which brings up another point: when looking at modules, always also look at how certain modules can synergize with each other. In this case, you could opt for two different sets of possible uses, both with some major sonic plusses to them...but if there's two that are obvious enough on the surface, there's apt to be MUCH more lurking there, waiting to be discovered once they're in a cab.
