I worked with the X50 last night for maybe an hour. I'll be honest, I simply loaded up my go-to Lepou's Lecto solo patch incorporating the vintage channel. It has the Mokafix Cream tube in front of it, Sir2 after lecto with a favorite impulse loaded and my favorite reverb for some ambiance. I dropped the X50 in under Lecto for tweaking and comparison to the Lecto.
Right off the bat, I was impressed how good the X50 sounds. It actually sounded quite similar to the way I have the Lecto set up, and I love my Lecto sound. It actually feels as if it has a bit more gain than the Lecto. I really enjoyed the power amp options. Onqel, I would love to see these options left in the final version, or at least the option to choose from the most popular tube choices (maybe not all the ones you already have available in the beta). It's great to know you tackled working out the poweramp section at all! I was disappointed at the gui buttons not working but I understand you're working on that. I am correct in my thinking that only the red channel is selectable and the white buttons like "bright" do not currently work?
I didn't think the CPU usage was that bad. I was a bit scared from what Onqel was saying, but it wasn't bad at all, and the selected quality settings were perfect. The X50 did not sound bad at all even on low setting. I should state though I'm using a quad core Zeon at 3.16Ghz.
All in all, I thought the X50 sounded very good so far! A world of difference from the X30 in a VERY good way. I was doing direct comparisons to the Lecto which isn't fair I know, but I wanted to know which I preferred. It's already close, but I'll hold off final judgment until the X50 is complete. At any case, the X50 is already a weapon anyone should have in their arsenal. It's just insane that LePou and Onqel are developing such high quality plug ins and donating them to the community for free. Onqel, you really deserve a major pat on the back for your efforts. I know it hasn't been easy for you. We appreciate everything that you do! Thanks!
