EC5 Electrical Pin-Out and/or Complete Schematic

[Bill1983]

Does anyone have access to a PA3x or PA4x Electrical Schematic?

I noticed on the "Feature Request" page that someone had requested doubling, or more, the EC5 into an EC10.

If Korg would support a SW change I believe the hardware side of the effort could be quite simple but, without knowing the electrical pin out. I cannot be sure. Not knowing if there is even a power or ground on the EC5 Pedal makes it difficult, and potentially damaging, to determine which pins are performing what function.

Here is one

Pin 2 (DIN)is the common pin, the other pins are the functions to choose.
In the circuit it says 2 grounds, but I only connected the 2 grounds.
I made one my own and it works.
As long as you connect it this way, nothing goes wrong.

If I am not mistaken, there are a few (a lot of!) things that the EC5 can do that the PA4X doesn't have MIDI codes for. Yes, there are a few things that have MIDI codes that the EC5 can't do, but the integration to the OS that the EC5 has is far greater than the rather limited access to it via MIDI.

Check out pages 836-838 in the manual and think how few of those have MIDI codes for...

My only issue with the EC5 is that there aren't ENOUGH switches..! Ten would have been MUCH better. Or at least have the assignments linked to Songbook entry. Your needs vary radically depending on whether in style mode, SMF mode, live band use, studio use etc.. One Global setup is pretty restrictive!

I think my ideal multi-pedal layout would be a bit like a Keith MacMillen 12-Step https://www.keithmcmillen.com/products/12-step/ but with the buttons a bit bigger. That way, you have 12 buttons for hands free control AND a set of basic bass pedals should you want to kick it old school for a while! But no USB MIDI... just simple integration into the switch setup like the EC5...

Until Korg do an about face and start to take external MIDI control seriously, and add MIDI hooks to ALL the things missing from the EC5 selections (and much more!) it seems we are better off with the way things are...

Each pin on the EC5 input on the Pa4x is dedicated to a switch on the pedalboard, plus a common circuit ground, so there is no simple way of expanding the number of pedals. Having said that, the EC5 signals are "read" by a device that also receives the Damper and Assignable pedal inputs, the latter being analogue and variable, so it might technically be possible, but would require Korg to produce an EC10 pedal, a Pa4x software redesign, and reprogramming of the microcontroller that deals with these inputs, so not trivial.

Aad,

Thank you so very much! You supplied me so much more than that and I promise you, if there is anything that you ever need which I'm versed in, you will have it.

I don't check the forum unless I'm on my very secure system because of it being "Not Secure". I'd gladly dedicate a server to the forum as well as maintain it just to get it on a SECURE SYSTEM. If anyone is listening, I am serious,

Thanks again Aad, I'll keep you posted on my progress,
Bill

I totally agree with everything you stated, however, having worked in all disciplines of automotive electronics from design, manufacturing, reliability, quality and sales in my 30 year career, I've found that when an OEM sees a potential profitable product with much of the design work completed, it is not unusual for them to take ownership and bring that product to market.

As I'm not looking to profit from this, other than having a much smarter multi pedal, that's all the more reason for Korg to take an interest.

With the current virus situation affecting all our members, family and friends, Korg HQ is no different so if I had a working prototype today it may be months before anyone at Korg sees it, much less reacts to it. As I now have everything I need from Aad, I can get started. Paralell to this, I have an extra NanoPAD2. My plans are to convert it to a footswitch array and use the rear USB Port for interface using the full functionality, less the x/y pad,so no software development will be required and the NanoPad2 editor will be fully functional.

My early years of keyboard were of a mixture of classical & modern. The 1st MIDI-Like instrument which I practiced on, helped maintain, and eventually performed on was built in the early 1920's. I was 15 years old. If that strikes interest, take a look at the attached link. Apologies for the site not being secure. It is a very old site.
