Yeah, that’s exactly what I do. First in my ancient waveshaper “Shaper”, then in my fairly old VCO “Kitchen Sink”. As I’ve noted, I think Kitchen Sink does more or less everything that Pony does: TZFM, waveshaping, different waveform outputs, sync. It, too, uses oversampling only, and no minBLEP.
You might also look at the new super saw copy. He uses a different technique that looks interesting. There’s a good video there that explains why that technique is better than mine. Here’s the thread about that: FLAG (free) Prodigal Son (Band Limited Super-Saw Oscillator with Noise and Amplitude Envelope)
