What you do like and dislike about the M50?

[aaronpico]

I love the sounds.

What I dislike is the cheapo/fragile build of my 61 key.
Jacks & knobs should be chasis mounted.
I had to send mine in for repair after 3 months of light use; the left channel outputs were cutting out. The service center re-soldered the left output section, and it worked fine until this month. Started doing it again. I just shipped it out today for it's second repair.
I am losing my enthusiasm about this board. I don't like the plastic'y quality. Compared to my old Roland XP-30, and my Kurzweil PC1SE, this board feels like a toy.

I'm considering the price range, cause it's a very good machine for it's price.

Like:

• Lightweight
  Versatile
  Small depth (11.57") fits very well on my "studio"
  Turns on very fast

Dislike:

• No dedicated octave sw buttons
  Weird sound when looping tracks, (I should do a video of this cause it's strange) I have a lot of issues with the sequencer.
  I don't like changing banks and keeping the number of the previous one. I'll love to select a program/combi on a bank B, switch to bank A select another program/combi and when switching back to bank B to have my previous program/combi selected. I think that's an easy fix and could be customizable on global settings.
  I need more buttons & nobs

About the sounds well, to me, I find them a little thin but OK. I'm happy.
