This is normal: > [@1222 Tuner VCO Triangle Waveform Output Volume](https://lookmumnocomputer.discourse.group/t/1222-tuner-vco-triangle-waveform-output-volume/3014): > > 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](https://lookmumnocomputer.discourse.group/t/hero-and-sidekick-vcos/5179) on) that scale and offset the 3340 outputs to make them all ±5 V, but Sam’s modules don’t. > [@Roadhog](#): > > As a new user it will only let me add one pic > [@New users: Why can't I (post images) (send PMs) (edit wiki posts) (etc.)](https://lookmumnocomputer.discourse.group/t/new-users-why-cant-i-post-images-send-pms-edit-wiki-posts-etc/6115/1): > > Because you’re brand new here.
