My friend owns the Legacy Controller and yup, the build quality on both are pretty much the same. Only difference is that the key-bed and overall size is bigger. It's like the followed the exact design, but just made it bigger.

Oh yeah, I hear those things have a mean LPF sweep

My MS20 Mini arrived yesterday!

After 4 hours of programming its safe to say i'm in love with the thing! Build quality is excellent with no wobbly knobs (at least on mine), and the sound is extremely close to the original. This is undoubtably an MS20

Yeah I'm loving mine. Had a Friday night to spend with it, and was up until about 4 in the morning.

I'm a getting a rather annoying low frequency hum when I plug into my interface, anyone have any ideas how to mitigate/eliminate this?

Buzz? Like interference buzz? My guess is to move cables around and unplug things until you get rid of it. What I do

If you have the MS-20 connected to the same computer with a USB cable, then you are most likely getting a ground loop. Two ways to fix that is getting a ground loop isolator for your interface and making sure any USB cable being used in your audio set up is double shielded. There's generally two sets of coding on the wire that will say something like 28AWG/2C and 24AWG/2C. If the two sets of coding don't both have 2C after the slash mark, then it's a cheaply shielded USB cable and should be replaced.

Hey thanks for the suggestions. Any recommendations for a ground loop isolator or good USB cable?

Good bit of info, didn't know that

The ground loop isolator I use is from Radio Shack:

I noticed there was still a slight amount of hum in the background if I cranked up the volume on my monitors super high, but then I stumbled upon an old Hewlett Packard USB cable which I used with one of my Korg keyboards and it stopped the noise completely. Honestly, it's hard to point out where to get the better shielded cables online because I usually buy these used at thrift stores by digging in the electronics bins. I've seen some stores selling USB cables for as high as $30 and you can't even see the coding on the wire because it's in a package, so I suggest just digging around in thrift stores or any place that has used computer parts so you can actually read the coding on the wires.

Awesome thanks man.

The USB cable I'm using is the one that came with the interface when I bought it like 5 years ago, so any writing about coding has long faded off the thing.

As for the ground loop isolator, it looks like RCA to RCA, so I don't know where I would connect it. Are there other variations?

Re-Member · Post by **Re-Member** » Mon Jul 15, 2013 10:22 pm

There are probably lots of variations with different sized cords, I just happen to use this one because my interface is a Tascam US-100 and I can only record in stereo using RCA wires. I have all my gear connected to a mixer, then use two "1/4 male to RCA female" cables to make a stereo connection to the ground loop isolator attached to the interface.

Ok thanks. The hum is happening even when the USB cable is disconnected so I'm thinking it must be a ground loop.

Also, to avoid any confusion, also listen to the Mini through a pair of headphones without being connected to the interface. You mentioned a "low frequency hum," which I assume is ground loop problem, but be aware that the Mini will always have this low layer of hiss mixed in the sound. If you are hearing the hiss through headphones, then it's not an interface issue. The Korg-35 filter is known to be rather noisy, which might be confused as being defective.
