Hi! I am new here, and have questions, and since I am unable to post a new thread, I hope it's ok to ask here?
I have been using a Paia 4700 modular system since the 1980s. I have accumulated double the modules that I began with as some were gifts, and some I built myself in the past few years. I am in the beginning atages of putting together a Eurorack system, and want to be able to interface my 4700 with it. I will start with a Behringer 960 sequencer, 962 switch, and 911 ADRS modules. I'm hoping to integrate the 4720 Paia VCOs with the 911s, but might need a Behringer 961 trigger converter? I also have been succesfully using several Korg SQ-1 sequencers with the 4700 modular system. Anyone who can help me figure out how to interface a Paia 4700 with the Eurorack format? I'm not at all an electronics DIY geek. The only Paia style modules I have built are passive: mono reistance mixers and transposers. Thanks in advance!

I guess your old PAiA has banana jacks (I've seen people swap them for other types). You could buy something like this, or make one yourself:

(If you have a ground banana jack in your 4700 system (or on its PSU) this should be connected with ground in the eurorack system.)
As I don't know much about PAiA systems, I can't say if the audio signal levels or control voltages will match.
It is usually not a big problem, but you need to know if the PAiA can't handle negative voltages, like bottom halves of LFO signals. This can be solved of course.
Also, eurorack uses the 1 V/octave standard (filters, VCOs).
For a comparison with you 4700, this is the Doepfer signal standard: https://doepfer.de/a100_man/a100t_e.htm#:~:text=Signals%20in%20the%20A%2D100
This standard does not cover all eurorack manufacturers/modules unfortunately. Mainly, there are differences in envelope voltage levels: +5, +8, +10 V. This may not matter too much, but it will decide to what extent you can open a filter or a VCA.
