It might seem insignificant - but: if you use two of those synths with
different Effects afterwards, you get phasing effects!
similar if you have multiple output ports:
[JACK]MIDI allows to timestamp midi-events. - So the synth-osc's
themselves could be in sync. - try to start two of them, invert the
polarity of one and check if the resulting signal is zero. (bitscope)
If it is, add a LADSPA DJ-EQ (1901) to one of the channels, IIRC that
introduces a latency of 3 samples on that channel and you should hear
some phased signal.
