I’ve been having some tracking issues with one of my Mangroves recently, so I’ve delved into the trimming procedure outlined in the manual. I’ve never calibrated an oscillator before, and, while I’m pretty confident I’m following the instructions properly, I think I’ve somehow made it worse, or at least not made it any better. The oscillator shifts upwards about a quarter tone when I plug 0V in, and is a semitone out when I give it 2V. Tuning it to 80Hz at 0V and then putting the 2V in gives me around 330Hz and I can’t seem to get closer than that. I’m using a Maths and a Blinds for my voltages.
Anyone done this before and/or got any tips?
Edit: I’ve been able to get it down to 320Hz with 2V and the tracking sounds much better. Still quite a noticeable shift in pitch between having nothing plugged into v/8PITCH and putting 0V in there, but I’ll survive. Post can be deleted.
