Hi,
After seeing lots of videos about modular systems, I'm planning my first

ModularGrid Rack

I'm using a beatstep pro as controller.
The choice for a 62hp from intellijel, is because I'm planning multiple little cases as one big case. Next case it would be for drums.

What do you think.¿

Well, I can't see what you're doing, but I can guarantee you that what you're planning will be expensive and rather pointless. Cases are some of the biggest expense in Eurorack, especially since they come in as an "up-front" cost when you're starting a build. But hey, let's do some math...

So, right now you're talking at least TWO Palette 62s. These go for $299 a pop, so $598 gets you 124 hp of space, plus 62 hp for Intellijel-format tiles...we'll call those 31 hp, as most tiles are sort of "half a module". 93 + 93 = 186 hp, with me being charitable. But as far as JUST the 3U modules, you've only got 124 hp.

Now, around here the Tiptop Mantis is generally considered the best all-around starter case. And they give you 104 x 2 hp for a total of 208 hp...for around $350. Definitely FAR cheaper...and as for power and ergonomics, they're pretty damn good. Plus, if you need 64 hp for a certain module subset...in the Palettes, you're screwed. But in a Mantis, it's easy. Which brings up the next point: small cases are really more suited for "mission-specific" builds...like adding a modulation "sidecar" or some such. And while it IS possible to mash a modular into one, you're going to have to make a lot of compromises that will wind up giving you less while costing more.

The best rule of thumb for case sizes is to whittle down a module complement to your desired result...then double the case size that it calls for. Sounds stupid, but the fact is that there's a buttload of "in between" modules that are the "glue" that makes the rest of the build work, and they're the ones everyone forgets. So, when you remember that there ARE important uses for some attenuverters and the like, they're going to need space because you're going to need them.

Now, as for the drums...this is another rabbit-hole. Yes, you CAN get loads of drum modules. Yes, the BSP HAS trigger sequencing. But this doesn't mean that you MUST do that. Fact is, if you just go out and snag something like Uli's RD-8 or 9 (or 6, even), you could get TWO of those and still not come close to the cost of doing that in modular (and yes, even in a Palette 62!). Nor would the functionality come close in terms of sequencing and integrated functions in those drum machines. By all means, yes, do your master clocking in the modular (Pam's to the rescue!) but DON'T just throw a couple grand at an issue that can be solved for less than $500.

So, yeah...that's without even seeing the build itself. But then, with how you're planning to do that, just the details about the cases alone are sufficient to indicate an impending cash bonfire. And since money works better for buying things than using it for kindling, I strongly suggest a rethink here.
