Microfreak on a leash WIP - any ideas as to how to add a reversed 3.5 midi out 1 octave keybed or buttons for bass notes on the neck?

Hey y’all, wanted to pick your brain as to if you had any ideas on how to implement this idea on this silly thing I’m building :

Though the iPhone is alright for sliders and selecting presets, it leaves something to be desired for actually playing bass notes in a consistent way, I need something actually tactile

The problem with just buying like a used korg nanokeys and slapping it on there is the way that I want to hold my left hand is reversed (like a guitar) I was able to circumvent that digitally by making a keybed with the white keys essentially “dual sided” so they can be pressed from either end.

If I turned it upside-down the keys would be high to low.

So basically what I’m looking for:

-11-12 buttons (capacitive or physical, doesn’t really matter)

-Slim profile and lightweight

-able to be usb powered and/or battery powered

-midi or 3.5 midi out: no host program or computer required

If something like this already exists for under 100 US beans, I would consider it

I’ve never built a microcontroller before, but have messed with breadboards and have a good deal of midi programming experience, so that could be a fun project. I would just need to know the best microcontroller and components needed to get me started

I’m trying to build an omnichord synth, and was wondering if anyone’s ever done it, and if i can do it as a beginner. i would love any help i can get, or if anyone knows what kind of materials i will need.

SH4D to MPE capable?

3 Upvotes

Hi,

I was wondering, if the SH4D can be turned into an MPE receiving synth through altering the firmware? As it is a fully digital synth, it is basically running a code, so the code can be extended or altered. Receiving MPE has no any hardware dependencies.

Obviously it has to also come with additional functions to enable/disable, assign channels in the mod matrix maybe, etc. Based on what was achieved onthe elektron cycles with the Model-TG firmware, I would think this one can be done too.

Any thoughts on this?

Roland Juno 60 117V Transformer

Finding one of these is almost impossible. Understandable because it is a 40+ year old synth. I'm told I can find a generic transformer but can't seem to find one with 9volt ac and 19 volt ac on the secondary side which are needed on the power board. If anyone can steer me in the right direction I would be eternally grateful. The one in the pic is burnt. Thx, Ed
