I don't have the METER module actually. Which oscillator module are you calibrating ? Is it patched like it says in the wiki ?
This module can be used for oscillator calibration. Take the Midi out CV to your oscillator CV in, Pick a simple waveform out and put that into the Meter module in. Put the Meter module in Osc. Calib mode and follow the instructions on the screen.
Yeah, I've already calibrated my oscillators. I had to calibrate two FMOS and two WAVETABLES. It works well, although I haven't plugged the oscillators back in. It'd be nice to have the trim pot on the front of the so you won't have to take the oscillator out.
I never felt like I needed to calibrate them as well. But will do for sure when receiving the precision adder... Since you already calibrated couple is it simpler with the meter module. Kinda thinking about it but would only use it for this or a cool oscilloscope going on but wouldn't add anything to the patch sonically....
