Nice overall, too bad the standalone doesn't have more features.
JakubH 25.06.2021
The build quality seems excelent, also it looks good.
It has a lot of ports so I am quite happy there.

I will be using the standalone feature most of the time.
It has 3 modes that you can cycle through with the button.
1/7 mode makes sense (1 IN to 7 OUTs).
7/1 mode is also fine (7 INs to 1 OUT).

But what the hell is "pass-through"?
4 INs to 4 OUTs? Well, not quite :-(
The manual says it will route 1 to 3, 2 to 4, 5 to 7 and 6 to 8.
How is this different to just plugging the cable directly where you want it.

Or is this like a MIDI patchbay feature? Except that ports 1-4 are on the front of the unit so you'll have 2 IN and 2 OUT on each side.
I thought that this would be like a hybrid between 1/7 and 7/1. Not exacly sure if that would be somehow hard to implement or whatever, but having a patchbay feature seems useless to me.

I mainly wanted a MIDI merge device so this will be fine I guess.

UPDATE: I ended up returning the unit and bought a Blokas MIDIHub instead and it's all I ever wanted and more ❤ (google it - it's awesome).

Some good ideas, but some annoying flaws
ASBM 19.11.2021
This is an interesting device which provides more functionality than most midi interfaces. But there are a few flaws which stop it from achieving what it is trying to be.

PRO:

- Very well built.
- Great price, although I would have preferred it to be a little bit more expensive if it meant it could have included what I note below.
- The function that each port can be an input or an output makes it really flexible in most setups. This should be implemented in all midi interfaces.

CON:

- The USB ports at the back can only be used when the device is plugged into a computer - and then only as a standard USB hub. There is no option to route MIDI between the DIN ports and the USB ports internally. This is a missed opportunity.
- The three options in standalone mode are fine if they cover what you need, but it would be better if there was an internal MIDI routing and filtering system. Then the user could decide themselves how the device is used. Again, missed opportunity.
- The lack of a power button is annoying. You need to unplug the device for the LEDs to switch off.

So overall, some good ideas, but it feels this device could have been a lot more. After trying to fit it in my setup for a few weeks, I have decided to sell mine and buy an iConnectivity mioXM instead.

CJ
Great MIDI interface
Connor Josef 21.09.2021
It has all the features you could want, however it's standalone functionality is a lot more limited I discovered. When plugged into a computer it does everything you want. Standalone you only have limited options.

When using as a MIDI thru box when standalone, you cannot select which port is the input, it has to be Input 1 which is a bit annoying as I want to keep this in a rack and have a rear port be the input so I can freely plug and unplug things into the front facing ports.
