Dave's excellent Hammond midi controller debuts


Recommended Posts

Thanks everyone so much for the compliments! The group of people that I can share this with, and who actually appreciate it, is pretty small. My wife allows that it is "pretty" but I can hardly bore her with all the details.

 

To answer a few questions:

 

Right now, I am controlling VB-3 in my DAW. I have a Receptor, but I don't think that is a suitable host. The reason for that is that I am using over 90 CCs on Midi channel 1, and Receptor uses those for controlling the mixer screen. Besides, it's big and heavy. So I want to build a single board computer to run VB-3 live - the equivalent of what is in Mojo and Hamichord.

 

However, V-Machines are getting blown out right now, I should probably just pick one up to hold me over until I do something else.

 

I may decide to mount it in the controller itself to make it a true organ, or I may decide to build it into a 1U rack. However if I do that, there's room in there for more than one...

 

Someone else asked about how much I had invested. That's a tough question. I kept close track of expenses for about 3 years, but in this last year I just gave up.

 

It's definitely a one-off. Some of the extreme stuff I did to reduce weight just would never be practical in a production environment. For instance, there is over $300 in carbon fiber material alone in it. Building the first of anything is ridiculously expensive. I made mistakes with the custom circuit boards and had to throw them away more than once.

 

I would guess I am out of pocket between $2500 and $3000, probably somewhere in the middle of that range.

 

The flat top on the case was deliberate. In fact, I made the organ 1.5" deeper than it strictly needed to be, so that a Nord Stage would not hang too far off of it.

This.

 

I feel certain that, with all the comments you've received, you know that we appreciate the skills, Dave.

 

My wife tunes me out when I talk about topics such as this. And that's OK. I certainly understand.

 

So, keep posting! This is the kind of stuff we live for. :cool:

Looking at your stunning controller solution, I asked myself whether a standard blow out VMachine will run upcoming VB3-2 too or only VB3 1.4 at max.

Do you have any info from Guido on this ?

 

Can be we´d need the faster dual core ATOM to run VB3-2, but eventually not because it seems there are ressources free for Key-Performer 2 on the dual core ATOM bord used in Crumar MOJO.

The only thing I have from Guido is a listing of the current Mojo SBC:

 

===================

The Hamichord/Mojo is currently based on a Intel D510MO mainboard with

1 Gb of RAM, a 1 or 2 Gb DOM and the Behringer UCA-202 USB soundcard

soon to be replaced by a custom made midi/audio interface.

===================

 

which is dual core, right?

Yes ...

It´s the same 1.66GHz Atom we see in Korg Kronos.

 

VB3 1.4 runs flawlessly on a 1GHz single core VMachine and Kronos runs a shitload of synth-engines and sample processing on the dual core 1.66 ATOM.

 

That´s why I wonder whether VB3-2 will run on a single core 1 GHz Atom (in a VMachine) too or what´s the necessity to use a dual core ATOM 1.66GHz to run VB3-2.

Maybe, it´s not only for the sound engine but to operate all the other controls and MIDI in MOJO/Hamichord too.

 

As far I understood, all the operation of controls and MIDI is already done inside your controller design, using other electronic components.

Only the computing device for the sound-engine (which shall/will be VB3-2) isn´t build in actually.

 

It might be out of interest for all the guys buying ready to play gear,- but not for the guys being interested to get their customized gear.

 

I googled a bit (end customer prices incl. VAT):

 

Intel D510MO = EUR 67.-

Behringer UCA 202 USB = EUR 24.- (Thomann)

1GB DDR2 667MHz RAM = EUR 10.-

2GB DOM (IDE or SATA),-

I was too lazy to google different prices,- at max. EUR 50.-

Software plugin in addition,- EUR 100.- ?

That´s all for just only ONE piece of engine.

 

I wonder whether we should organize a KC group buy for your controller incl. the engine or not.

Depends on availability of "Hammond" type parts like drawbars, rocker switches and C/V knob.

Keybed is another story.

 

What about a DIY set ?

Did you think about selling plans and instructions ?

Beautiful work on the wood, and great attention to detail and professional fit and finish.

Will you build others? A "Moe Mark II" perhaps?

Wow.... I cast my vote, as well, for a Keyboard article. Could easily see that single manual version driving VB3 in my rig. The design looks tight, nails the technology, and is classy. Great work ! :thu:

That is a brilliant work of incredible beauty and inspiration. I cant even find words.

 

Please tell your wife that a guy on the internet named "Frogmonkey" said so-- that ought to convince her. :D

 

I followed your threads about this project with excitement, and it is very gratifying to see it finished! I would really love to see a video of it in action :)

YOU ARE DA MAN! From my view this is a very-nearly perfect Hammond-style performance controller! Only one set of crucial components missing, my brother. WHERE ARE THE START/RUN SWITCHES? Ok...I know they're not necessary for power-up/power-down, but the only authentic way I know of to trigger generator wind-down effects.

 

Alright...it's a stupid comment, and I am highly impressed with this thing! I WANT ONE!!!

 

Congratulations on this monumental achievement!

 

Best,

Fox
