I have a steel guitar I made with the e-bow tech built in and from the beginning I have put a short motion variable volume control at the end of the bar that that makes an elegant one handed affair, either hand. That pressure sensor hopefully can be wired to the end of a short rubber tube which is the "ring", bending your fingertip to express! Now your other hand is free to play on another keyboard. Half as much hemispherical computation to do.

Красава, сам делал?

You, sir, are a genius! Thank you

I wish you can buy an Ondes style midi controller

Hi, how can I get the scheme, I adore Martenot and I would like to build me one, Thanks

Do you happen to have updated schematics on this project? I would love to try and build this, a forever dream of mine.

You people amaze me. Still there can be hope on earth!

Could you explain how you programmed the Ondes Martenot patch on your VST? The image on your blog is poor quality and I can't see exactly whats going on. Thx!!

That's fucking insane, man. Best Ondes Martenot recreation I've seen so far. Can't wait to build mine!

If this isn't steampunk af then I don't know what is.

I need this....

Do you think you can share the schematic of your project with me?. Thanks in advance

Amazing! I've been trying to figure out how make a midi controller that would have the sliding note ability of the Martenot. The pitchbend idea is brilliant! Thank you for the plans!

Would you consider putting English instructions on your blog? I would really appreciate it. I am looking to build this myself but am not experienced enough to make my own plan - yours looks/sounds best compared to other projects!!

If anyone is looking to make this, i'd suggest using a softpot instead of a pulley system. String slippage is a real problem.

Shut up and take my money now.

Hello Mitsushi, I am amazed by the Ondes Martenot and your project! I am hoping to try and recreate this myself and was wondering if you could share with me your final electronics schematic (electronics are not my strong point). Thanks a lot for the inspiring work! :)

DIY guide?

What computer are you using? If it's the apple iBook is it good? I'm thinking about getting one since i'm on a budget for good music production laptops.

Beautiful.

素晴らしすぎます。

Great work, man! :)

Does the pulley size matter in this project? Is it part of your calculations?

This is kinda like an Etherwave Theremin that you touch but with more than one synth sound.

Great "Blade Runner" cover. Fantastic job on making a MIDI version of this amazing electronic instrument

Bravo, la musicalité.

The digital ondes martenot made by Louis Martenot (model 8) had around 8000 values for 6 octaves (which is 1333 values for an octave). Your glissandos sound very smooth, although 'only' 256 values for on octave (which is 5 times less precise). Are you sure no additional adc's with higher resolution are involved in your project? : )

I am building this instrument off the plans you provided off your website. The musical group I am in is doing some arrangements off the score from the movie "There Will be Blood". It was written by Radiohead's Jonny Greenwood, who plays the Ondes Martenot. Any suggestions or help you could give me would be much appreciated. I am super excited!

This is BRILLIANT! BRAVO!!

you're a fucking genius!

What would it cost if i asked you to make a midi controller like that for me?

Some manly tears were shed

Awesome for sure! Hey, I have a suggestion for a better way to give the user more control over the vibrato sensitivity, which will allow even more realism to this great instrument. Although there are many ways this can be done, I will describe one that is easy to visualize from text, but you could hack a laser mouse to do the same thing if you hacked the driver code. I will describe a more old school approach though. A major advantage will be to allow the player to do vibrato by wiggling the finger perpendicular to the string, more like how it's done on fretted instruments. It's actually an easier vibrato method to master. Unfortunately I am not aware of how you have your multi-turn potentiometer in this circuit, but if the output resistance is being converted to, or controlling digital, I am assuming you could write code to make the vibrato more or less sensitive based on the rate of changes the string makes. Either way, here is a possible approach for adding another simple control sensor that could be used to change pitch, volume, or both. MORE ACCURATE VIBRATO SENSING- SInce I have built many guitar effects and have repaired lots of organs ( I play both) the idea came to me that you could use a simple LDR circuit to vary vibrato by simply taking a piece of the stiff grey 'mica like' spacer cardboard like what you find in all types of electronics to protect shorting etc ( I'll call it 'greyboard')... DYI BEGIN...just a start, you can go on this and add to it: -So cut square piece of this greyboard about 30 mm and pass the string through two 10 mm slits which are 5 mm from center ( and so 10 mm from one another). Next pass the string through one slit and back down into the other slit so that the cardboard is flat against the string. The string should have no resistance by the cardboard pinching it, but enough to move the cardboard with the string as the string moves FWD,REV, and PERP. (DO NOT PASS STRING THROUGH ANYTHING YET, test ok) - Next, using the same grey cardboard make a small shallow 'fort like' square perimeter [ a topless/bottomless box] that is just slightly ( maybe 5 mm) larger than the square. Now label sides of box F,B,L,R (front,back,left,right). - Next, on two sides- L and R, cut a 15 mm slit horizontally from center. The width of the slit should allow string to pass through freely with plenty of space above & below the string. - Next, get a piece of thin black felt and that is enough to cover the L & R both inside and out ( so 4 pieces of felt). With light glue adhere the felt over the two L & R slits,* *BUT FIRST* lay felt on hard surface and with a sharp utility knife or razor cut a slit into the felt that is the same 15 mm length as the L & R slits. NOW you can line up the slits in the felt to the slits on the L & R slits ( felt inside & out) [ the felt will keep outside light from getting into the box, but will all string to pass freely]. Next, place the thin piece of greyboard in the inner perimeter of the 'topless/bottomless box'. Now thread the string through L slit into the two slits on the square piece as described at the beginning, and finally out of the R slit. The LDR arrangement- Essentially the freely moving square will act like a shutter which as it moves will change the level of light passing from one side to the other side which has the photo resistor. Since a guitar or violin is more apt to have a 'tighter vibrato' the higher up the neck (toward the bridge) you go, then you SHOULD place this LDR system on the HIGH SIDE of the keyboard this will have the same effect. As far as analog to digital LDR circuits, that's fairly easy to deal with. I am simply providing a way to do the 'hardware' of the device. You can look at how the Morley foot pedals use these shutter arrangements. The Gulbransen Organs of the late fifties and early 60's used this system as well. In fact if you wipe the dust off of the light bulbs you can increase the volume of these organs:) In the case of the Morley Wah, Volume, etc. pedals, if the red indicator light is off the pedal won't operate. I used to get them for a steal in this condition. Good luck and of course in 20 minutes I'll have thought of an even easier way to do it. The key is to get the brain thinking:)

Hi.... Totally in love with the controller u did.... i went to see the details on your website but out of some draw... it's a fact, i don't really understand as i'm not familiarized with japanese... I'm really, really .. really interested in building the same controller. do you think there would be a way for you to send me de schematics of your realization and/or programming in details? best to you and once again: bravo :)

Please make these available for sale! Oh please!! :D It's the closest I've ever seen anything get so close to the real deal.

:-)

Thanks for this Mark!

Thanks tttsss!

Sorry for late reply. I created some voices like ondes martenot. Its not secret :-)and I will share the captured data soon.

awesome, this is the best one i've seen yet,... i've made one but it didn't really come out as good but this seems to work well i had thought of using an fsr but thought it wouldn't be as accurate, you've demonstrated it can be

hello, you could share me a circuit diagram? I can not understand the pages you wrote in the description, please. What are the components I need? Please.

This is a really well made instrument! Great work! First time seeing this video, just now. You play very expressively.

I've been dreaming of playing an ondes martenot or a french connection but they're near impossible to get in my country (philippines) and too expensive. I'm heading to Tokyo this December and I would be so glad if I could order one from you. :)

good！是非売って下さい。

One of my dreams is play an ondes martenot, and it can be possible thanks to you... just a little question Is it a preset from MonoPoly?? or you created that one?? Can you please share it with us??

epic

blade runner!!!!!!!!!!

WOW!!!!!!!! you inspire me!! :DD

Just to jump in, if you have a patchable synthesizer, such as Thor in Reason, you could extend it beyond 4 octaves. I've just put together a patch that lets you use a 10 octave range on the pitch bender. Excessive, I know, but it could be useful. It all depends on how the synth's patching system works though.

Really really gorgeous performance. You should separate it out so I can listen to it on repeat easily! Probably my favorite DIY thing I've seen in a long time. Excellent construction, really inspiring result!
