LMNC simple 1v/oct oscillator volume question on some of the outputs

1222 Tuner VCO Triangle Waveform Output Volume

Hello, I’ve recently built the 1222 VCO and whilst everything appears to be working fine, the triangle output seems a lot quieter than PW or sawtooth. I couldn’t find much info on this, and I’m just wondering if this is expected due to the nature of that waveform or if there is something else down to calibration that I’m missing? Apologies if there is an obvious answer, I’m fairly new to this! Thanks

That topic is about the 1222 module but the same applies to the simple one.

There are 3340 based oscillators, like the Thomas Henry VCO Maximus and the Kassutronics VCO 3340 (which I partly based my VCO design on) that scale and offset the 3340 outputs to make them all ±5 V, but Sam’s modules don’t.

Because you’re brand new here. Welcome! Thanks for reading the FAQs. The Discourse platform puts some hard limits on what you can do when you first walk through the door, but it only takes 10 minutes to get past them: [image] There are higher levels that take more time and effort but getting to Basic is quick and easy enough.
