4720 VCO strange behavior..

Last night I replaced the caps of my 2720's power supply and fixed some issues with the keyboard. When I hooked up the modules and put them in place, I started out with the VCO, and it seemed to work fine. And it even wasn't as mentioned in another post. I proceeded filling the space with modules, s...

Paia 2720 BPF improvements?

Hello, I'm trying to explore some possibilities of improving one of my 2720 BPFs. I'm primarily aiming for a wider resonance range, up to near or total self oscillation, and a steeper cutoff range, but I'd love to hear any other suggestions to improve the quality of the filter, or even turn it into ...

Re: Patch Cords, MIDI, Etc. -- pdf document

I found that the speaker pin plugs from Radio Shack work very well, and you can make patch cords out of them in no time without any soldering. Plus the pins are ribbed, which prevents them from getting pulled out by accident when moving patch cords around. http://rsk.imageg.net/graphics/product_imag...

Re: Paia 2700 midi implant

How did that happen? Just curious because I was thinking about using midi implants for my Paia VCOs and some of my other synths (Korg 770, Yamaha CS-15, ...)

Re: Red/black vs brown/black jacks - which is original 2700?

Hmm I too wonder if there was a period where they simply ran out of the red jacks or ordered or received the wrong kind and simply added them to the next run of kits instead of returning them thus doing a limited run of accidental "special edition" kits? I wonder how rare they are and how much more ...

Re: Paia 2700 Power Supply Capactor Replacement Question

That is very good news. Now if you could help me out with the topic about the 4720 VCO and 4730 VCF, that would be even better ;)

Re: Red/black vs brown/black jacks - which is original 2700?

Moving back to the original topic - I stand corrected, the modules with brown jacks read 2720 on the boards. Still makes me wonder why those have brown jacks like the original button keyboard version. Early editions perhaps? Was there a time where Paia continued to use brown jacks for the 2720, then...

Paia 2700 Power Supply Capactor Replacement Question

I need to replace all three of the big capacitors on the power supply, and I wanted to do this quickly. So I went to a nearby Radioshack but they were out of those that matched the ones on the board (25V, 1000uF) and the next best ones that I saw were 35V, 2000 uF, so I got those instead. My questio...

Issues with 4730 VCF, 4720 VCO

I finally got around to replace most of the modules of my first Paia with the 4700 type modules from the other one, plus a 4780 sequencer and 4720 VCO, which I both purchased on Ebay. The VCF has the following problem: When I patch any of the waveform outputs of the VCO into the VCF, there is no out...

Re: Red/black vs brown/black jacks - which is original 2700?

Ok, here ara some quick clips demonstrating how the PWM on my first Paia behaves: 1. PWM from the 2720-2a VCO - note how it doesn't seem to track right with the keyboard scale, and how intense and distorted it sounds? (I know, the keys need some serious tuning) https://app.box.com/s/8yov8xuo3wiseblf...
