@easyrider That's a very cool setup. I also have a Fredde Ikea desk and am considering getting another one for music production, if I can make the keyboard work underneath.
I was about to pull the trigger on a Buso Audio
Artist88 or
Artist61 desk (better alternative imho to the
Output Platform desk), but the Fredde is far more affordable.
The desktop cutout also allows to not only play some of the keyboard without having to pull it out much at all, but even when you pull it out more, you can actually stay much closer to the desk, accessing computer keyboard/mouse, as you can see the Komplete's Kontrol screens and knobs in the cutout.
Do you have any more photos of your setup and details on the type of hardware and materials you used to make this happen?
How do you find it in terms of height? As I was experimenting fitting my Komplete Kontrol underneath, which has to be low enough, but the pots/knobs not to hit it as you slide the keyboard to/from under the desk.
I would consider even raising the desk ever so slightly, in order to not have the chair too low when I am playing for longer periods of time, as the surface of the desk is @73cm (71cm from under that worktop to the ground), but because of the (4cm high) horizontal bar running under the desk, the clearance between the top of the drawer board and the underside of the worktop would need to be at least 12cm for it to work comfortably with that Komplete Kontrol keyboard (which is 8.5cm high), so the bottom of the keyboard is @59cm from the ground.
Add to that the thickness of the drawer board (which could be cut at the front like the Output Desk keyboard tray I guess, in order to bring the legs closer), say 2cm, then your keyboard tray's underside is only 57-58cm to the ground (most keyboard stands tend to be at least 60-61cm high for comparison purposes).
If you were trying to put in a weighted keyboard underneath (like a Nord Stage 3 88 @19Kg, or a Studiologic SL @13Kg, which are both nearly 13cm high), on top of the larger clearance which means that 59cm distance Ground-Top of Keyboard tray must decrease from from 59 to 54.5cm, you have the weight factor to consider with the need to have a very sturdy pullout drawer mechanism.
It would be amazing to get more details from you on the setup
