I have a question about the MFOS volts per octave calibrator.
Is it best to power it from the PSU that powers the VCO/VCFs that are going to be calibrated or can the calibrator have its own PSU?

Hi

When i built my mfos vco calibrator i had it connected to the modular +/-12V supply and had my volt meter & frequency meter in the studio (lounge) so i could tune/ calibrate them at the synth.

If you have a power busbar with sockets for your modules an easy way is to fit the same power plug to the calibrator as the modules have or wire it to the +/0v/- chocblock connector strip if its a small project Smile

Dave.

Hi Dave

many thanks for the info. Taking the power from the same supply as thing you want calibrate did seem to be the logical thing to do. Iwas just curious if having the calibrator with its own power offered any advantages.
