I have a Yamaha RM1x where some of the buttons were quite bad. I decided to replace all of them while I had it open. A couple of the encoder and the volume cap was missing so I replaced these also. The soft buttons were Omten D3XJ and I bought these from a vendor on...
Updating the firmware via MIDI SysEx to the latest version I could find (v1.028beta). Used “Syxex Librarian” in MacOS to do the transfer but MidiOx on Windows should work fine also.
Fitting the E-Licktronic Nava in the metal case. Had minor issues with the scale LEDs not fitting properly due to the holes being too small. I also had some issues with the back screws as the spacer was off some fractions of a millimeter. Later on I managed to bend these slightly so the screws...
So we’re getting closer to the end of this project, hopefully, here I solder the master section and I try to power it up for the first time and see if I get any sound at all from it.
Crimping all of the cables for the E-Licktronic Nava. I decided to use connectors on both ends of the cables as I am not fond of soldering cables directly to a board, so twice the amount of crimps! If you are going to do this I would recommend buying 5-10% more of the crimp terminals....
This Korg Poly-800 Mk1 had suddenly started to behave oddly. If it made any sounds at all they were inconsistent and random. This would indicate that the memory is corrupt due to a bad battery. As I understand it there was no internal battery mounted in all of the Kort Poly-800 Mk1, they required batteries...
Soldering the I/O board of the E-Licktronic Nava TR-909 clone. The only issue here was that the DIN connectors did not have the correct spacing between the outer pins so I had to modify them as I did not want to wait for “proper ” ones. This worked out fine!
This video shows the soldering and troubleshooting of the E-Licktronic Nava Sequencer section. The biggest issue I had here was that the supplied LED holders were too big and did not fit side by side. I resolved this by using some 10MM high M3 spacers that I had. These fit perfectly; You just have to...
