[sdiy] Novation peak NCOs

[Rutger Vlek]

Glad you mention it! I was surprised with the news too. Especially surprised about the amount of investment they made for this moderately novel route. I've been reading the promo blub on their website and have to admit I got enthusiastic, but I'm no expert in FPGAs so I'm wondering what more objective reviews have to say about this approach.

Are there down-sides, besides the cost of this brute force approach? Is aliasing really a big-enough problem to justify such an investment?

They brag about not using 7 but a generous 8-bit for various controllers. Which I don't feel is that generous at all, as I've seen figures around 12 bit more often these days.

Best,

Rutger

It uses a sample rate of 24MHz to generate classic analog saw, pulse, tri waves, etc, then feeds them through conventional analog VCF, VCA, etc.
