After 350 kits sold (including 556 SIDs), I have finally got to the end of the waiting list. Woot!
There will be a final batch of 50 kits in November. I don’t have plans to keep lots of pre-packed kits in stock, therefore, once the last batch is sold, YOU CANT HAZ sammichSID! There are still plenty of kits available in the final batch.
Yes, this is some shameless self-promotion to boost sales so I can finish with my routine 50 kit batch and sell off all the PCBs and parts I have in stock.

As said in the previous post, this midibox project will be designed to control NI Traktor software.
Inspired by a commercial product i've estimated the number of components:
50 Pots
9 Encoder
150 Leds
160 Push buttons
5 Faders
USB interface
The pots, encoders, leds and buttons numbers are an estimate, remains that their number can change while the project goes ahead.
So, now that we know an estimate of how many components we need, we can start to looking at the ucapps.de modul
Ok, i'm starting this blog to have (and to give) a "document" of my work about the building of a Traktor Controller.
I had this idea in my head since 2 years, and i'm starting now because i'll use this project for my "Multimedia Design degree thesis".
I'm not entirely outside of the Midibox projects, 3-4 years ago i've succesfully builded myself a MidiBox64, but i've never touched something related to the assembler, nor the new C platform programming. Simple way, i've never programmed for Midi
Abstract
Discussion of the problems limiting the length of SRIO chains.
Some causes of signal integrity problems in transmission lines are mentioned.
A Working solution is presented.
Introduction
The problems limiting the length (physical length and the number of chips connected) of DOUT shift registers has been canvassed during the development of my Midi Keyboard LED Display (MKLD) project. MKLD Itself is the subject of an upcoming blog article. Suffice it to say for now that the desig
Simple keyboard zones
Rather than have the whole keyboard output the same midi channel (hence same sound) we may want to have "left hand ->Bass" and "right hand -> Treble" parts. This is accomplished by having a "zones" in this case upper and lower parts of the keyboard separated at a certain note on the keyboard ("split point").
A simple keyboard zone split is simple to define: for example output note numbers above a the split point on a different channel.

This is what worked for me:
1) Download and install openocd 0.2.0 (earliest version after 0.1.0 available as prebuilt *.msi.
Btw, 0.1.0 is preferred for compatibility with the mios provided scripts)
2) In Program Files\OpenOCD\0.2.0\drivers is a folder contained in ft223.zip, unpack this folder to a temporary location.
3) Attach the JTAG key to USB. After "Found New Hardware" wizard, install from the location of the folder in step (2)
4) Invoke OpenOcd with the following command line: open
Jaycar is an electronic component retailer in Australia.
They have stores in many locations and for this reason are a convenient source of parts.
The QP5518 (Jaycar's cat. number) is 2x16 yel/grn LED backlit display.
It is pin compatible with the Core32 EXCEPT VDD AND VSS NEED TO BE SWAPPED.
Why this is the case I have no idea, but it's sure to bring some to grief.
FIX: Simply peal back wires 1,2 of the ribbon used and twist it before crimping the IDC connector at one end. Thats Brown and R
MBSEQ V4 remote controlled by my new Button/Duo-LED matrix prototype.
The frontpanel hasn’t been created yet, and it’s difficult to push the mini buttons without button caps. But playing with this toy is already a lot of fun!
The BLM firmware is running on a dedicated PIC based core module and communicates with MBSEQ via MIDI. The optimized protocol is fast enough to achieve high refresh rates between 350 fps (if only a single line is changed) and 20 fps (if all 512 LEDs are chan
I have decided to put my MBFM on hold. And build a MB6582 first. This way i can see how a frontpanel design works out before i order a new design for the MBFM.
Indeed. After i got a message from shuriken. Seems something wrong with date setting.
Anyway the software is completely new. This was a suprise to me.
So start blogging!
Here a first impression of the virtual MIDIbox SEQ V4 for the iPad.
As you can see, there is some space for additional buttons or display functions.
Due to the delayed delivery in Europe I won’t be able to test and finish the emulation before june…
Currently I cannot estimate if the timings will be so stable like on a real MBSEQ, however together with the upcoming OSC option we will get at least a nice remote control.
A quick demo of a keytar I built out of a Commodore 64. It uses two SID 6581 chips and was made using the Midibox Sid platform from www.ucapps.de. Better video to follow later.
I finally got my MBFM properly running. I had some trouble with the bankstick. Which weren't detected. After some measuring i found out the input voltage was to low. So i altered the cabling on the multi voltage transformer. Now its eating 8 volts instead of 6 and its working quite well.
So after that i could upload the patches and start enjoying some sounds.
Hello everybody
much time hast past since my last entry here, but this project is not dead.
what happened in the meantime?
my studies ate up much more time than I planned, so I had to change priorities.
but its not all about math and machine construction ;-)
first step was creating all the pcbs i need for building the controller and - my very own
PIC-Burner. I used his lovely little pre-project to gain some advanced skills for the
etching machine at work. thanks to my boss, i got
I began the documentation about the interface between my protodeck controller and ableton live software.
It uses a max for live patch.
All is there: http://www.julienbayle.net/diy/protodeck/#m4L
I ordered a front panel for my Sequencer (using Wilba's design) from Julian at www.thebeast.co.uk.
The panel looks great but as anybody following the discussions will know, it isn't easy for Julian to make threaded blinds so we decided to go for blinds that are large enough to fit a hex spacer in. They are 5.72mm diameter x 2mm deep.
As JB Weld isn't that common in the UK, I thought I would try Loctite "Bond Loc". This is available from Maplin http://www.maplin.co...?ModuleNo=46006 a
