The AT → to VCF slider is not working on my unit in regards to using it with the pitch bender. Has anyone else had this problem. Seems to have stopped working after a firmware update.

> Can anyone verify bender to VCF is working - running the latest OS 1.2.6? Bender to DDS works fine (as does dest (both, upper,lower). However setting VCF to any amount has no effect with the bender moving horizontally. Set env and VCF to middle position after init patch, set leftmost toggle switch to trig. FWIW, setting DDS to zero for both bend and lfo2 still results in bend when toggle set to LFO2 on. Filter modulation via vertical bender modulation works fine.

Yes, this is a known issue with v1.26 and should be fixed in the next update 🤞🏽🤞🏽🤞🏽

Let’s hope U.D.O. is listening/reading…

Hi folks. Please download the latest Gemini and Super 8 OS which resolves the bender to VCF missing functionality amongst other improvements. Find it at [www.udo-audio.com](http://www.udo-audio.com)
