Hi Jeff,

Thank you for the kind remarks and thorough review.

All of your points, here and across the series, you can consider
acknowledged and I will work to adopt them in the next version.

There were a few loose ends and questions throughout the series which I
intend to address over the coming days. The first one is below.

I will simply remove the conditional. If no wavetable was loaded, the
register will have a value of 0, which is no less worthwhile to report to the
user.

Best,
