j-Omega Electronics board is well designed flexible and reliable and cost efficient. It’s simple to use and program. To program plug your MIDI keyboard in to the MTP-7 board (if you make a hash of it just start again.) So let’s say we are in the configuration mode. (See instructions)
When the j-Omega Electronics board goes high the pallet magnet will remain closed.
before you handle any kind of electricity / electronics you must read and fully understand any instructions that were given with any item you are about to work on.
Play middle C on your Keyboard (MIDI note 60) the board will assign middle C to port 1. Now restart the MTP-7 board by switching it off then back on again, now play middle C on your keyboard or MIDI-playing device. The MTP-7 board will now open port 1 only. Regardless of any different notes you may play. You can only use all the outputs at the same time but there are some limits to find out what the limits are see the instruction that comes with the MTP-7 board. But in my tests with my 31-note organ I had no problems at all. I ran the board fast and slow made it work hard with no problems in anyway. I suppose one could say I tried to destroy it, just to see how far I could push the board before it let go, but it still works fine.
