MicroDexed - DX7 to go


#41

Ahhh … BTW … i’m ready to try MicroDexed :wink:


#42

Of course I like it! But I already have cases and only need front (and back) panels. Will show pictures soon.

#43

:+1: Very good! I am currently writing the manual. When it is ready you will be the first one who can build a MicroDexed (hmmmm… what does that remind me of? :wink: )

Regards, Holger


#44

Ramón can also build front panels. I think that you only need cut, anodize and serigraphy. It could be cheap. When you have the design, you could ask him …

Just to keep the thread alive. :wink:


Before sending the first (alpha) kits, I have to do the following:

  • connect the encoders
  • getting LCDs and encoders for the kits from China (this may take up to four weeks)
  • writing some code for the UI (selecting bank, voice and volume) - just as a first start for the UI
  • write a build manual

I think this will take some time… so stay tuned!

Would you consider using a OLED 2x16 display? More expensive, but so much better looking. Adafruit has them. Cheaper from China.


#47

Currently not, because it would make the UI design more complicated (…for me. What I mean: I know how to use the LCD and I have so much things to do to get this project running, so I don’t want to change the design now).

I think MicroDexed should be more a kind of a playing instrument, so a LCD based UI is IMHO enough. If you need more flexibility with programming: No problem, MicroDexed understands Yamaha-DX7-SYSEX :slight_smile: You can use an external programmer (software or expensive hardware) or create sounds with the VST of Dexed and copy them to the SD card. But I will also add a way to change parameters with the encoders and LCD in future releases.

But, perhaps the next version will have an OLED?

Just wondering WHY DX7 hardware programmer is so expensive :wink:


#49

You own this programmer???

I am thinking of using a module with one encoder, a LED ring around and a small uC onboard which “speaks” a simple protocol (I2C?). With about 60 of those I2C-encoders a DX7 editor would be sooooo coool!

No, I just played with it for a week.
But it’s so expensive that, with the same money, you can buy two microsoft surface pro 4 tablets, install CTRLR and have a tons of custom panels, like the one I used on the Nova serie :slight_smile:


…or the Roland D50 one

…and why don’t talk about the monster: the SY77 :smiley:

(how the hell did yamaha think that a single data entry controller was enough to program that thing?!)

Ok ok… I’m off topic. About the hardware version, in hardware panels I quite don’t like encoders when a potentiometer should be used. Yes, potentiometers are a PITA when changing from one preset to another, but there is some workaround (like the “catch current value” used by modern novation synths). And, well… it’s a “feeling” matter… like those “new” Moogs with encoders, just… no! :slight_smile:
I want to build an hardware control panel for my Mininova, but there will be blood…ahem… potentiometers. MANY potentiometers… :smiley:


#51

Because apparently about 95% of the ones that came in for repair still had the original factory presets.
There is an opinion that memory presets were a major backward step for creative synthesis . . .


#52

Yep, a very good reason.

(Elka Syntex Preset #46, anyone?)


#53

Aaah you see open up a DX7 enthusiast and deep deep down they are polyphonic analogue right throu’

A break throu’ bit of Dx . . .
:slight_smile:

Course, some of us grew up on Alpha Dials . . .


#54

I still have one :wink:

#55

That’s very nice software… will try to find a DX7 panel.

#57

New pictures from the prototype:

I have some of these cases, but they you will have to cut out the front and lasercut the front and back panel by yourself. I currently have no lasercutter.

I am also waiting for some parts from china for the kits…


#58

LASER? It’s basic metalworks… all it needs is a couple of metal drill bits and a nibbler :wink:

BTW I loved those general purpose cases, and I used a lot of them (plastic version) in the past. A loooooong time ago, aluminum ones were too expensive so we recycled all those Hayes-like modem cases, building new front and back panels in wood. WAY WAY WAY before 3D printers :slight_smile:

#59

Me, too. My case was a Rittal CMC-TC system. We have replaced them with newer versions. The inside parts were given to the recycling yard and I kept the housing :slight_smile:.

Hm… I have some problems with the Linux version. I cannot create any working binary or plugin. Have you already used CTRLR on Linux?

Also the DX7 panel seems to have some bugs (sys the internal analyzer)…
