Ketron SD2 USB + vArranger for sale seperately
« on: August 07, 2016, 07:34:04 PM »
Hi everyone.
 
1.) I'm selling the unique Ketron SD2 USB (Make your vArranger truely mobile!)
2.) I'm also selling my USB stick with vArranger and lots of extras.

1.) The Ketron SD2 package includes:
The compact Ketron SD2 orchestral wizard with the following connectors:
stereo line out 2x chinch (rear)
stereo headphones 3,5mm with fader (front)
USB connector cable to PC (approx. 45 cm, rear)
USB connetor cable to MIDI controller keyboard (approx. 60 cm, rear)
(In the thread below you can see the assembly process.)
Value approx. 350,- Euros.

This SD2 can be an ideal protection for your valuable vArranger USB stick:
Inside the strong metal case there is a USB socket for a stick with up to 6 cm length.
To enjoy optimal results from the SD2 and controller keyboard please use a USB 3 socket in your PC for enough power.
If you want, you can even recondition it to it's original state...
I posted the building instructions on this forum.

2.) The vArranger USB stick includes:
vArranger full version, updatable, registered with Dan. (349,-)
Verbatim 16 GB USB stick: retractable USB connector to give it extra protection + small stabile connector for keychain etc. against loss.
Best Korg and Yamaha soundfonts to start vArranger on your PC even with no extra MIDI sound equipment. Bought from Dan. (198,-)
Lots of MIDI files and enough free memory space left.
Dan wants 50 Euros if the vArranger changes it's owner. I'll pay that.

Looking forward to your offers.

And this is how it all started here on the forum:
--------------------------------------------------------

Hi everyone.

Looks like it's possible to build a mobile solution using the Ketron SD2:
Power via USB or via Smartphone-Loader or via usb power bank.

Got myself a SD2 and opened it.
On the board I found a 7805 that converts the voltage from 12 V to 5 V.
For all those who'ld like to take a look: It's a big three legged thing that has a cooler screwed to the board.
Took 5 V from a smartphone usb power supply and put it to the leg that's closest to the volume slider.
Ground to the srew holding the 7805 cooler.
And it worked.
Made correct music after a press of the vA "panic" button!

Word of caution:
Do NOT tinker around like this with the SD2 as it will void your warranty.
And the built in 500 mA fuse will not protect it anymore.

I measured about 200 mA.
Some usb ports cannot handle this much.
(That might explain why some SD4 don't seem to work with Win7 (?)...

If you have a USB3 port or a usb hub with extra power supply that might be OK.

Who dares to create a usb powered SD2 now?
I would like to put the SD2 board into a Korg Micro Key and have it all connected to the pc via one usb cable...

Yes, Dan, that's right.

You discard the 5pin MIDI cables and add a few other lines.
And that's IT.

Got it working now.  :)
SD2 with just a usb connector and no power adapter is just awsome!  :D

Of course:
No responsibility if anything goes wrong.
Ketron warranty is void.

Now here is how to
(+) get rid of all MIDI cables
(+) never use the mains connector again
(+) protect the valuable Varranger usb stick
(+) be able to connect a usb controller or keyboard

Here are the steps:
1.) Cut the cables of a midi-to-usb-adapter and solder them to the bottom of the SD2.
2.) Cut power switch and the 7805's 5v pin.
3.) Solder red and blue cables and a connector for power FROM the usb hub TO the SD2
4.) To be on the safe side:
Take out the fuse, shorten the pins of the multi-pin connector on the right of the SD2 board
and put a piece of plastic between your stuff and the SD2 board.

5.) Plug everything together.
On the left:
USB-Out Cable  (for attaching an extra keyboard or controller)
USB-to-MIDI-adapter
Varranger USB stick
On  the right:
USB-In Cable (Connect to PC)
Power for the SD2.

Now get your soldering irons and have fun ;-)

Looking forward to your results.
Any extra ideas are appreciated.

Just to boast:
This is my setup, now.
I seem to like Korg ;-)
And the microkey has surprising low latency with Varranger via bluetooth.

Actually:
I don't know how to use all of the functions of the nanokontrol and the nanokey studio (xy-pad? knobs? sliders?) with Varranger.
If you know, please let me know...

The surface keeps in place with just it's "rear leg".

It supplies power to the SD2.
So everything can run on batteries.

The speaker has it's own internal 6600 mAh power bank.
So it will not drain the setup.

Great job on your setup.   I wish I could do the same with my SD4.   The SD4 has issues with its USB port and I use the MIDI din.

Is it metal that you cut and fold for the case?

Elvis 
I love the retrofit PA900    I would like to do this to my Yamaha psr 3000 or PSR s950.   I love the sd1000 for the sounds but most of my production has been on the PSR keyboard thus a lot of the nuances do not carry through to the sd1000.   have you seen anyone do this for the PSR line , I could even use a  version of the PSR S950 without a keyboard , I would use a keytar.

Dan,
it's plastic profiles to keep weight down. Surprisingly stabile.
And easier to saw and drill...

Hayseed,
The best types to convert seem to be Korg Pa300, 600, 900 and the new 700 and 1000 because you can easily extract the front panel with the Electronics fitted to the rear of it.
If there are Buttons intgerated into the case you'll have to cut up the case and fit it to another Base.

 I did that with a Korg Microarranger. That was ok.
And nearly started to a Tyros. But that would have ended in tears... ;-)
