3DS music tool Rytmik Ultimate

It's definitely a huge improvement over the previous titles. It's sort of a tracker and a sequencer mixed into one. There's a bunch of chiptune sounds, and you can draw your own waves. There's a cloud feature where you can upload, download, and rate other songs.

Eh, honestly if you're asking yourself that, it probably won't be. I only bought it because I buy every music creation tool available on 3ds. 18 dollars is kinda steep, especially if you already have other options for making music. I just plan on using it for little sketches that I can remake on LSDJ later.

You can make full songs with it. You put together blocks of 4 beats and then string those together. Each block can have 4 instruments. It doesn't have unlimited patterns but it has enough that you won't run out any time soon.

Never tried Ultimate but I tried the Retrobits one and it is really cool !!!
Btw are you Tao from the Atari ST scene ?!

(Disclaimer: I've only tried Rytmik, Rytmik Retrobits, and Rytmik Rock Edition [what was I even thinking with that last one]. I don't know if they've made things better in Ultimate but I highly doubt it.)
I personally don't care for Rytmik that much. The interface is a bit lacking for me in terms of fine-tuning options and I'm not a fan of the "slide up and down to find the note you want" controls. It's kind of hard to explain to someone who hasn't seen it. It's basically like the switching from the Game Boy version of Nanoloop to the smartphone version. Having to use a touchscreen to slide it up and down to get to the note you want rather than using buttons is weird, man. And the touch screen controls are too sensitive. I have to move ever-so-slowly to get to the right note and if I don't hold the stylus in JUST the right way as I'm lifting up from the touch screen it thinks I'm still moving up or down and the note changes. I don't have it with me right now so I can't double check this right now but IIRC it doesn't even give you any indicator of what note you're even playing (like showing C, D, E, F, G, etc. when you're changing the note in nanoloop or having a piano roll to choose from in the KORG applications) unless you go to a separate screen entirely.
The whole process just didn't flow very well for me.
I personally prefer DSN-12 even though it's pretty expensive (though I think they're having a sale on it right now).
Rhythm Core Alpha looks interesting but I haven't had a chance to try it out yet.
KORG M01D is pretty neat, but I wish it had more options for effects and maybe a kaoss-ish screen like DSN-12 and DS-10 have. M01D alone just sounds too much like an auto-play midi I'd hear while visiting a geocities site in 2003.
I'd really love for KORG to make another application that merges both M01D and DSN-12. Maybe someday...
