In the interest of fairness, i noted that the input level can also make quite a big difference, there’s a threshold after which the input level will not be matched 1:1 by a throughput level but the shape will distort as the disparity between levels gets more noticeable, even on a sine wave … it can be very accurate up to a certain point and the level is increasingly constrained, but the shape will change
So I ran these in Max to overlay them, but with a reduced input level to the filter stage (reso boost was off, but it seems to make no difference to the shape at these input/filter settings anyway) … i tried to match the energy at the nominally flat resonance 25 setting so that a tri/saw were roughly level, then left all settings and levels alone, except for resonance and i varied the shapes, this time presented showing the influence of resonance on the apparent transparency of the filter block, it gets more analogous with higher resonance at these osc/filter settings, but it may be problematic at other frequencies
attached for completeness - square is still suffering the most visually, there is some phase shifting due to the odd post-filter waveform and the detection algorithm struggles to find the rising edge
seeing this has not changed my view of how to use the machine, i still use my ears, but if you’re striving for a certain sound, it may be good to appreciate some of these nuances … resonance really plays a big part in this
So, sin/tri/saw/square Nord shapes (only varying the A4 redo, nothing else) (all else as per post above, including caveats) Note : no A4 oscillators
In all shapes, the increasing resonance is possibly having the effect of reducing the energy levels (away from the resonant freq) though it’s harder to read for the saw/sqr
