Neat project! |
|
|
Hello-
Looks like a really cool project! I look forward to the schematics and figuring out how you're doing velocity sensing, as it looks like you're not just doing a time difference. Is there another page where info is being consolidated, or is everything going to go up sequentially on the forum?I'm also working on a project like this, at diykeyboard.org. I'm not nearly as far along as you guys, so the site is very much a work in progress.
I'm hoping to shoe-horn an 88 key velocity sensitive key scanner onto an atmega168 plus a few logic family chips. I'm currently trying to figure out a switch matrix scheme that will work with my uc; looks like I might have to re-purpose some ADC's. I only recently got into microcontrollers, so the FPGA stuff is still a little magical to me.
Cheers,
Drew |

Drew, Scott, Elektro80 and others,
Just a very quick note on the "Thomas Henry" Keyboard....
Bill/State Machine and I have been cranking on this big time since mid-autumn and are extremely close to releasing. We've gone way beyond the initial scope of the project (my corporate higher-ups would call this project creep) and this thing is way more than a clone of Thomas's keyboard controller. Bill will release this at his discretion as he's the project boss. Right now, he's got his hands full with his job and a E-M performance at the end of the month.
The design is quite a bit different from what Drew is attempting so there should be no overlap.
Now that's all I'm going to say as I don't want to steal Bill's thunder, 'cause you are all gonna love this!! |

Yes, the Keyboard controller that we worked on was inspired by the Thomas Henry design but it is not the Thomas Henry design. The new controller is called the "Integrated Keyboard Controller" or IKC. It can be directly interfaced to all Fatar keybeds up to 5 octaves. The keybeds are now available here in the US and are distributed by Analog Haven.
http://www.analoguehaven.com/doepfer/mke/
The IKC can be the heart of any DIY analog/digital keyboard controller project and will be expandable. I saw the need for this because I did not see much DIY work being done on building your own custom MASTER keyboards. It will be announced soon on the Microcontrollers and Programmable logic subforum. Currently I have over 70 PC Boards getting manufactured right now and will arrive on April 25, 2008. The IKC will also come paired with a MIDI channel changer & Digital display PCB that will interface to the IKC. A daughter board is also planned to add many MIDI control functions.
Stay tuned and keep your eyes on the forum

Hi, State Machine. I was just wondering if there was an update on the IKC! This would fit into my plans for several projects very nicely! I've been thinking about ordering a couple of the Fatar keybeds from AH, but wanted to see what the status of the project was, and if there was an estimate on PCB/processor cost would be. Any details would be much appreciated!

wow. that's my project of the year! it will be the first component of the performance synth i am planning to build. GREAT.
(the 3oct fatar keyboard is already sits waiting on my workbench...) _________________

Great Matthias Thats sounds good to me. I will hope that more folks will want to DIY their performance or studio master keyboards. I really like those Fatar keyboards and they are now easily available here in the US.
Anyhow, hang on just a bit longer. Documentation is a necessary evil.

Phil, Fonik and all,
As the primary tester of the prototypes, I'd just like to let you know this is one sweet keyboard. If all it did was analog, I would be 100% satisfied. The midi out just puts it over the top. There are some nice features that make the controller an extra CV processing module as well. Plus the ability to play a midi synth as a mono synthesizer is just way cool. You're really gonna love it! Now if I could just find the time to finish my completed unit! |

Hi Bill,
Nice work, congrats. Would be possible to have more than one set of cv gate outputs and the ability to output 1.2 v/oct?
Cheers,
R. |

Ringer,
My unit has 3 CV outs, 2 gates and 2 triggers as my usual voicing is driving 2 VCO's, a VCF and 2 ADSR's. You just need to wire extra jacks in parallel....there's no magic to it. You're basically creating little multiples.
Watch the side panel space though! Mine's like 150mm X 267mm and I'll be pressed to squeeze in extra controls when the expansion feature midi daughtercard becomes available.
As for scaling to 1.2V, I'm sure that's possible as the scaling is set with a trimmer and 1.0V/Oct is somewhere in the middle of the range. |

Hi Antman,
Thanks for the response. I will mult the 1 v/oct and trim the second output for 1.2 v/oct. My bad, I should explained it a little better, I meant more voices. Ultimately 6 voices would be nice, if not I put a 4 voice midi2cv unit on board.
Regards,
R. |

Johans,
It's pretty close to being released. Schematics, pcb artwork, BOM, etc are done along with some nice add-on boards from State Machine. Bill is currently writing up the fairly detailed, (and therefore lengthy), documentation and I would guess as soon as that's done, it should be ready to release.
Bill: correct me if you have anything further
I'm currently finishing off the first complete unit in my workshop. Last night I was finishing the control panel. I just need to mount the control panel components and wire it up. I've been collecting photos of my work and sound samples of my testing, so there will be lots of audio-visuals when we finish. I really like being able to play my polyphonic midi modules in a mono-synth mode. I've had a lot of fun playing one of my Emu Proteus modules in parallel with my TH SN-Voices and being able to do those neat 1 finger trills. |

Very cool!!
I am very excited about this project!
I want to build it into a "portable modular" design. Portable is in quotes because my modular is in MOTM format
Count me in! |

Dan,
You got it pretty well covered there my friend Between this, writing new music for Electro, and my work demands, it's a handful. In addition to house hunting
I have seen some preliminary pictures of Dan's keyboard and must say, it will be a nice addition to his studio.
The actual thread for the "Integrated Keyboard Controller" will appear in the "Microcontrollers and Programmable Logic" sub forum but a link will be placed in this thread so nobody will miss the project.
The project documentation will be available for all to build this. The code will also be available for anyone to download and program their CPLD. I will, however, be offering printed circuit cards and parts kits for the project if anyone wishes to purchase these items.
Thanks all,
Bill |

Oh man, that photo just lit a fire!!! Consider my interest in investing in a ridiculously huge keyboard officially rekindled. Maybe add a certain ribbon controller to mine for a certain je ne sais quois...

And I fully echo what goodrevdoc said about the ribbon controller.......
WOW!
I can't wait guys!!! Excellent work! (assuming it works half as well as it looks) |

Hear, hear! This looks great, antman did a top notch job! I will definitely be building 3 and maybe a 4th of this one! A 4 octave keybed seems to be the sweet spot to me, although for my studio keyboard, I am thinking 5 octaves. Can't wait, this will be a great one to build!

I designed a cable breakout adapter board that creates a very easy interface to the beautiful FATAR keyboards. It transitions from the keyboaard connectors (AMP Micromatch) to the IKC connectors (Molex KK style-Inlines). I successfully interfaced my "brandy new" 5 octave keyboard from Analog Haven ($125.00 + Shipping) to the IKC controller and it works like a charm !!! I have attained a complete stock of PC boards for the IKC, Completed and tested MCC boards, and have parts kits also. I will also be making a batch of adapter boards I mentioned above.
Also, I believe that Scott's Ribbon controller will make a beautiful compliment to this project. You will then have MIDI, Analog CV, with all kinds of modulation sources. You will then be able to express your music with both a standard keyboard AND versatile ribbon controller
I will FINALLY (Sorry Guys) transition this thread to the "Microcontrollers and Programmable Logic" sub-forum. I will announce the transfer in this thread, then lock it. The announcement will be made "Sticky" on top of that subforum. Then we can find out who wants to build "master" keyboards for their studios or "gig-rigs" ........
I have attached pictures of adapter board that connects the IKC and the fatar keyboard.
Dan and I are now doing preliminaries on the expansion module that will add MIDI machine control and MIDI controllers (CC's). Talks have been going on behind the scenes by Scott Stites and I about a possible "Appendage" interface to the IKC expansion board that will quantize it and send it's output over MIDI ..........
Thanks,
Bill
