VCO-1 Saw Wave Voltage Offset Increases when Freq is Increased

[dijikul]

In v1.1.6 the Saw wave on VCO-1 appears to demonstrate a bug when turning the Frequency up to the higher ranges.

Reproduce this issue by plugging the Saw Out from VCO-1 into a Scope Input like so:

The range of the VCO is cleanly within the middle range.

Turning the Frequency on VCO-1 up well past 75%, around 80 or 85 and above the Y-offset of the Saw wave appears to increase and is pushed upwards on the scope:

This does not appear to be an issue with the VCO-2 set in Saw mode, or in other VCO's that output Saws.

It's caused by DC offset, that big green lump on the left, (0Hz or very low freq), when you remove the extreme lows (with 4DCB) it looks normal.

And yes, it should not do that, so let us call it a bug.

I logged this in the VCV database, since the minBLEP code is part of VCV. In any case, it's a dupe: https://github.com/VCVRack/Rack/issues/1816

Haha - well, my old bug about this is no longer visible since VCV Rack doesn't have a public issues page any longer. Suffice to say that the minBLEP still has an offset. I don't think this bug has ever been addressed.
