Akai MX1000 User’s Manual and Service Manual

These are not yet available anywhere on the web, so hopefully this will help a few people out. Click here to download both.

If you need a new backlight, this mod for the S1100 works. It’s even easier with the MX1000 since the inverter is in a clear spot on the PSU PCB.

I have the MX1000 schematic also, but it’s really large and difficult to capture at a useful resolution. I’ll need some encouragement to get around to it!

      

AKAI MX1000 Aftertouch repair

Last minute programming at the hotel

I’m still using an Akai MX1000 76 key weighted master keyboard. This thing was made in 1991. I rescued it from a recycling centre in 2007. It has served me well, it’s even done the Body & Soul music festival! It’s got a comprehensive MIDI spec so I was able to set it up to run an entire show in Apple MainStage remotely- start, stop, patch changes and level controls. Its off-white colour (typical of Akai at that time) looked good with a white MacBook and white T-shirt. I’ve also helped out with a modern re-engineered memory card, so this keyboard would be good for several hundred patch changes with MainStage. Brilliant!

It is old though, so it’s time for some maintenance. Some contacts will have corroded, and some capacitors might be coming to the 30 year mark and so need to be replaced. So I intend to document maintenance for this machine, and share what official documents I have.

First up is the aftertouch repair guide from the Lynxxx website, which is currently down for maintenance ’til 2040, apparently! Very funny.

Problem: Aftertouch on my Akai MX1000 Midi Master Keyboard is not working

Possible cause 1: Aftertouch cable disconnected.

During transport, the flat plastic strip that connects the aftertouch pressure sensor to the internal printed circuit board may have shaken loose. Gently insert the strip back into the connector.

Possible Cause 2: Aftertouch cable worn.

When the cable has been jammed into the connector roughly a couple of times, the leads on the cable may have worn. You can try cleaning them with a qtip and some alcohol. If the leads are damaged, cut a few millimeters of the cable and reinsert it.

Problem: Aftertouch on my Akai MX1000 requires extreme pressure on the keys

Possible cause: Aftertouch pressure sensor strip corroded.

After some years, the leads “inside” the aftertouch pressure sensor strip will start corroding, forming a thin non-conductive layer that degrades aftertouch performance.

Solution:

1. Open the Akai
Remove the upper row of screws from the back of the Akai
MX1000. Remove the screws holding the top cover down. There
are three screws located on the right in a mirrored L formation and
five more on the left that are also in a (normal) L formation. You
may have to remove the two screws above the small rim
underneath the board too. You can now gently open the upper part
of the Akai MX1000 which will expose the internal circuitry and
keyboard springs etc. (I will add pictures of this procedure later)

2. Disconnect and remove the keyboard
Disconnect the flat cable on the mainboard. Rest the top cover
against something so it cant fully flip to the other side once we
remove the wire holding it. Remove the four screws holding the
small metal support in the middle of the Akai (that has a ground
wire on it holding the top cover). You need to remove this in order
to be able to take out the keyboard. Remove the large screws on
the bottom of the Akai that have rings around them. These hold
the keyboard itself in place inside the MX1000 casing. Remove
the remaining screws on the left lower side of the Akai that are
supporting the left side-panel of the MX1000. You can now gently
move this section (including the mod and bend wheels) a few
inches to the left, allowing you to lift up the keyboard from the
chassis.

3. Remove the keys
Remove the springs. Gently insert a screwdriver in the back ring of
the spring and remove it Be careful. These little bastards will
easily hit you in the eye if you don’t pay attention. Now remove the
keys. Start with the white keys first, then do the black ones.The
first key on the left is the “E”, marked with a double “EE” sign to
signify the first key (last key is signed “GG”, all others have single
letters). You can remove the keys by slightly shifting them towards
you and then lifting the ends. If they get stuck, give the little white
plastic hooks inside a little push.

4. Store the stuff
Make sure you keep all the keys and springs together in the same
place. Parts are hard to find, so you don’t want to lose anything
here.

5. Disassemble aftertouch strip
Once all the keys have been removed you will be able to gently
remove the upper layer of the aftertouch pressure sensor. This is
the white felt strip on the front part of the top. The top layer
consists of a felt strip glued to a plastic strip with some white
conductive material which is glued to the bottom layer with a sticky
Post-It like glue. You can easily remove this layer and press it
back on later.

 

6. Clean the pressure sensor
Once you have removed the top layer of the strip, you should be
able to see the two metal leads that acre causing the problems.
use a q-tip with some alcohol to remove the thin black film on top
of the grey/silver coloured leads. You may have to repeat this
process a couple of times until the strip stops colouring the QTips.
Don’t force it though. If you rub it too much you will damage the
strip beyond repair :-(. Gently rub the strip with some dry cotton
QTips to make sure everything is properly cleaned. Note the
difference between cleaned and corroded area in the picture. Wait
until everything is completely dry and free of any cleaning alcohol.
Now gently press the top layer back onto the pressure sensor.
Check the cable (see above) and reinsert the keyboard into the
Akai MX1000 case. Reconnect the flat cable, insert all the screws
into their original locations and close the cover.

7. Test it!
Select the System Menu and press Transmit. The display will now
show all outgoing MIDI data. If you press a key a little harder than
normal you should see the aftertouch messages scrolling by. You
can now assume your Mighty Marvel Pose #38 :-).

The album tracks part 2: For Gaza

It’s hard not to feel powerless against the human rights violations being committed by Israel. Back in 2014 when it flared up, again, I saw a video by Israeli film director Naomi Levari. A very brave move for an Isreali national. I composed For Gaza quite quickly, to raise some money for the Ireland Palestine Solidarity Campaign (IPSC) whose aim is “…to participate in international efforts to put pressure on the Israeli state to cease its oppression of the Palestinian people”.

The fund-raising was a great success, and this new album was an opportunity to do a remix of the track, and change a few things that were not quite right.

The process

The origin of the piece goes back to 1990 with the little Casio SK-5 8 bit sampler and the Yamaha CS-5 synthesiser. The heavy drums and the bass loop are sampled from that original tape with all the noise and distortion it had. The strings are a development of an idea from back then. I didn’t even realise this at the time. I just went for a performance on the keyboard, while listening to the horrendous news from Palestine with tears in my eyes. In electronic music, what you hear has often been programmed in the the computer. This artificially tight, sometimes robotic rhythm is one of the cool things about electronic music I think. But it’s good to have actual live human playing on it too! Towards the end of the process I was very tempted to move some of the notes around because I felt they weren’t quite on the beat. But that’s where the feel is. Sometimes, just because it seems to measure right it doesn’t mean it hits the soul! So I built up some layers of different string sounds, to give a Turkish ensemble effect, a sound I heard a lot in North Africa and Southern Spain. The slight variations in each part are just like what happens with a real string section.

The rhythm guitar is sampled from a jam session with one of my old bands, played by Ken Hayes. This was cut up in Recycle and the parts placed across the keyboard so they could be replayed. The lead guitar at the end is from the same session, with the notes and timing played around with in Melodyne, an amazing software tool that makes pitch and time totally flexible.

The atrocities continue, so please support the IPSC.

The Album Tracks Part 1: Orchestrion

This is a combination of atmospheres and sounds from the 1870s and the 1970s. The Orchestion of the title is an Imhof & Mukle Orchestrion Music Machine. It uses a wooden barrel with pins on it to open valves in over 100 pipes that are built like woodwind instruments such as clarinets and flutes. Basically, a large version of the barrel you would see in a music box. To run it, you wind a weight up to the top of the machine, and as it runs down it drives the barrel and pumps the air through the pipes. This one was located in Dunkathel House, where I worked in the recording studio. Here’s a picture of the actual machine in the house, courtesy of the RTÉ archive.

And my lovely wife Sally O’Reilly for encouragement both musical and emotional 🙂

Some of these ideas go back to 1990 when I first started to compose. I think it’s important to keep an archive of ideas and stuff to play with- play being the key word. I really enjoyed the process, with all the help and support. I hope you all can feel the same joy I felt in making this music. 🙂

BBC Radiophonics live at the National Concert Hall

I recently had the pleasure of the Radiophonic Workshop at the National Concert Hall in Dublin. This was a dream come true. When I was about 10 years old my father joined the Rory Gallagher Music Library. This holds a massive collection of recorded music and spoken word. First it was Goon Show tapes, and later the full BBC sound effects library. Essential Science Fiction Sound Effects Volumes 1 and 2 became some of my favourite albums and a major influence. 🙂 Continue reading
