Re: Are Doepfer a-155 CV levels safe to use with Sub Phatty?

I did try to measure the V out of the Doepfer, but sticking a multimeter across an output patch cable resulted in nothing. What's the best way to measure a momentary trigger voltage?

Re: Are Doepfer a-155 CV levels safe to use with Sub Phatty?

Good news! The answer from Moog is:

"Generally we advise 0 - +5VDC for Gate and -5 --> +5VDC for the Filter and Pitch.

However the CV inputs are buffered and can safely accept up to 12V probably, and will clip at anything above that."

Unfortunately Doepfer's manual for the a-155 is devoid of voltage level info.

I've emailed Moog tech, and will report back ASAP.

Re: Are Doepfer a-155 CV levels safe to use with Sub Phatty?

The Doepfer manual states these voltages for the whole a-100 ecosystem:

Trigger/gates: +12v

Audio signals: -5v to +5v

Control voltages (e.g. LFO): -2.5v to +2.5v

Control voltages (e.g. ADSR): 0v to +8v

So, bearing in mind that there will be some wonkiness if I send it negative voltages, my only ...

Are Doepfer a-155 CV levels safe to use with Sub Phatty?

Hi, recent Sub Phatty owner here, and thoroughly enjoying it :-)

I am sequencing it from my modular, specifically/usually the CV and trigger outputs from a Doepfer A-155 analogue sequencer.

Question: are the voltages from the a-155 safe to feed straight into the SP, or do they need attenuating? I ...
