The Blofeld Keyboard INDEED has both DIN midi in and out as well as USB. It’s only the Desktop Blofeld that only has midi in DIN…just for accuracy, as I have the Blofeld Keyboard.
As far as “overpowering sound”, that’s easily remedied with all other overall levels and there’s always use of compressor/limiter.
Save from the A4 and Virus Series, not too many synths have really outstanding effects on-board. I will freely admit the effects on Blofeld are not outstanding but I have always used outboard effects anyway and in my opinion the A4 is better/great as, dare I say, Lexicon ones!!! Yep, I said it!
As aforementioned regarding the “Waldorf Q being OLD”, it’s same age as Virus KB/KC and these are the deepest VA synths I have ever used and still set the bar for hardware and even some software. The Q Rack does take up 5 rack spaces but also happily sits at an angle as a desktop unit. If you ever have a chance where I fellow musician has a Q for you to take for a “test drive”, I think you would understand why it’s so revered.
Also note that the “old Waldorf team”, upon their prior bankruptcy, they all went over to Access Music to further develop the Virus Series. So, they both share some Synth DNA and that should tell you something.
Lastly, if anyone had to try to program any of the synths of late 80’s to early 90’s when the industry thought it a great idea to have itsy-bitsy screen, only knob was volume, if you were lucky…the Blofeld is a joy to program in comparison and it’s User Manual is quite well implemented. Try to program a DX7 and you will understand!
Good fortune on your quest!
