This didn't start as a blog, but I have a blog for almost everything else.
The old blog was getting too long so I started another one

Today I am feeling quite awful. I returned from my holidays and a day or two later started having tummy issues, I hope it doesn't last long. So while I wasn't feeling good I started playing the keys. I opened the four songs I haven't finished recording yet. I think Challenge is probably ready to go, Supernova/Supercollider just needs a solo and lyrics. Opus is still in an early stage, but could be completed quite quickly and Snowangels I couldn't even check as I don't have the D-110 hooked up ATM. No new aquisitions although I am keeping my eye on a couple of things. I am looking very seriously at a chip that would change MIDI clock signals into Sync-24 signals. My biggest problem would be that I would still have to monkey around in the inside of my EP-11 to make it work because the Sync-24 on the EP-11 is OUT only! I'm sure I could tap into the proper places to accept an incoming signal, but I would have to disable the panel controls. BUT then I could possibly use and sync the drums and appreggio. That could be alot of fun. I found a new way to set the JX-3P to not OMNI, just press POLY on the MKB-300! Easy. Still waiting for chips for my stupid amp, I ordered more from the states so hopefully I will finally have them in a few weeks. Then I can try to start repairing other things.

Well I moved the bass amp off of the bench because I installed the power transistors and it still didn't work. So I really wasn't planning on doing anything, but I thought I would just open the Jx-3p and see if the chip I need to replace for the MIDI upgrade kit was in a socket or not. I thought I had some sockets but after looking, I don't, so I figured I should see if I need to order some. Luckily it was socketed. Then I thought I should see if I can fix my repair. There is a crack in the panel circuit board, and I tried jumpering across by using wires connected to the closest solder joint. I retraced the paths to make sure everything was right, then I found a join that didn't seem very good. After playing with it, there was something that was preventing a good solder join there like an oil or something that I can't seem to clean away. So I used a different join and made a connection to the other bad place. I also added a jumper for the ground, just to make sure and finally I can access number buttons 9 to 14! I wasn't going to do any more but figured I could drop in the chip for the MIDI upgrade solder the one wire to the main CPU and leave it at that. I did that and it took literally one minute, so I unhooked the MIDI jack board and quickly looked at what I would have to do to that. After a bit of looking I decided I could probably put this together fairly quickly too. So I had to open 2 paths on the circuit board, remove a resistor and a jumper wire, then solder 10 wires on various places on the board. It actually took longer to put the JX-3p back together. I plugged it back in and tried it out. So number one all the number buttons are working again!! Then I started playing it with the MKB-200. I wanted to make sure the OMNI was off. It didn't seem to be as the MKS-7 was playing as well, then I realized the JX-3P was receiving MIDI channel 3, and ONLY MIDI channel 3! I shut it off and tried the velocity mode, that was cool, then I shut it off and set the MIDI channel to 1. Then I set the MKB-200 to send CC's to the JX. The first one was the VCA level and sure enough I could play with the volume. I then HAD to try the cutoff level, and that worked great too! I played with the JX for about a half hour and decided all was good. I guess I have to open the S-220 now. Hopefully it is something I can fix. Oh and I have 5 80017 chips I can drop in the acetone bath, when ever I am ready to try that again.

Progress has been very slow. I opened the S-220 and checked the voltages on the power supply and everything looked great, so my only guess is the capacitor by the cyrstal supplying the sample chip, or maybe even the crystal. Unfortunately there isn't ANYWHERE close that carries capacitors!! All I need is a 10 cent frigging part! So it is waiting. I also opened the MKS-30 and started removing the chips and dropped the chips I had into the acetone bath. Holy frig those chips were hard to remove! I finally just broke the last two out and will have to replace the legs. So I am just waiting for some DIP sockets (I couldn't get SIP sockets), they shouldn't be too hard to modify for the single 12 pin arragement. Then I will see if I have 6 chips that still work. I accidently broke one trying to get it out, so I have 10 80017 chips and 1 clone. Hopefully I can get both of these going soon.

Weird I thought I wrote an entry here, I guess I didn't. So I got tired of waiting and just hooked up the S-220 and it seems to be fine. Who knows? So about a week ago I worked the MKS-30 and installed the sockets. I put in and tested 6 chips and they seem ed to work so I thought I was done and closed it up. Turns out one of the chips won't work at first, but after some tinkering it will come 'on'. So I tonight I tried some of the other chips I have but unfortunately they don't work. So the MKS-30 is sorta working, I guess I will have to order at least 1 chip. 2 nights ago I opened and repaired the M-120 mixer, I replaced a couple of op-amps and it works fine now. (I think). So the tinkering continues.
