MIDI Thru box

Does anyone have experience with the MIDI Solutions T8?

It looks like one of the few MIDI thru boxes remaining in existence that has more than four ports. The only thing that worries me is that it is MIDI powered. I think this is really cool because in no way do I need more things to plug into outlets but I am just concerned for the stability of the power.

I plan to go from OT out -> MD in, MD thru -> MIDI box, then out to the rest of my synths. Any idea if the Machinedrum can power this box?

I have the smaller version (1x4) version of that and it works fine. I’ve never had any problems.

I have a MKII so things are looking good.
A little odd the DSI stuff doesn’t support MIDI power.

everything fine so far

I have the 1x4 as well. Works fine. Don’t remember exactly where it is in my setup though…

I have the midi solutions quadra thru (passive) and it works very well, never had an issue.

There’s no such thing as “MIDI power” and as handy as these boxes can be, they don’t really operate within the physical specifications of the MIDI standard.

Kenton still offers a powered thru box with 5 outputs, and you can often find second-hand thru boxes with more than four outputs on eBay. The Philip Rees V8 and V10 are especially nice.

If you have a soldering iron, you can get a kit of a 6-output MIDI thru “box” from https://www.tindie.com/products/hotchk155/midisplit-1-input-6-output-midi-splitter/ that you can power with a simple USB power supply from an old phone or tablet.

And if you don’t mind self-sourcing components, you can also get a more conventionally shaped PCB for a 5-output thru box from http://midisizer.com/midithru/

Does that mean we’re missing out on something?
I have mine powered by a SP606 and haven’t had any issue as long as it’s powered on to power the thru box.

If it works for you it works for you. You can’t really damage anything. It’s just that you can always end up with a device that won’t work with your unpowered thru box.

Yeah, my rig is packed neatly in a flightcase…so it’s pretty easy to turn on the sp606 so that I can fiddle with something else. It all acts a single instrument really as long as everything is powered on.

Midi Solutions Thru boxes perfectly work for me with my A4, be they according to official Midi spec or not.

Some devices won’t properly power those boxes but before you go through the pains of building your own thru box from scratch you can always just build your own power supply for Midi Solutions gear instead of buying their expensive power supply. All you need is a USB power adapter, two Midi sockets, a usb type B socket and of course a USB cable. That should be around 15$ all together.

USB gives 5V so no need for any voltage regulation. You just hook it straight up.

I need to get a MIDI thru box, I’m looking at the Miditech one because it’s cheap and it has MIDI filter functions. However, it is MIDI powered which raises some questions…

http://miditech.de/en-248-produkte-midithru

Does being MIDI powered mean there is a latency?

Is the Octatrack capable of supplying this MIDI power?

Is it more reliable to have a MIDI thru box with ac power?

Any useful advice is welcome! :slight_smile:

I have this. I have the OT going to three devices (AR, M32 and MIDI/USB for iPad) Works fine. No latencyí, as far as I can tell. Machines start right up at clock.

I’ve been meaning to work out the in-depth filter options over computer (the M32’s internal sequencer begins if it receives clock), but as far as power, I haven’t had an issue yet.

I moved this here because some useful info is already detailed above, plus there are a few other existing threads to glean some insights from, it’s helpful to collate them all together so the info is shared well :thup:

i scored one of these to replaced my midi solutions one. also use kentons merge box to feed controllers to the mnm. And finally, midi solutions midi processor plus is nice and simple to use midi filter (albeit, a bit overpriced).

Midi powered doesn’t matter except having to have turn whatever pets it on.

Is there a specific reason you upgraded from ‘MIDI powered’ to an ‘ac powered’ thru box?

I had a look at the Erica box but the huge power supply puts me off (I’m in uk so it would also require an adaptor). I have a compact Mackie mixer that uses a similar power supply and it’s just not convenient.

You can only push things so far, I’m not trying all 4 ports of my MIDIMAN (Now M-Audio) Thru 1x4 but i can drive two midi streams from my battery powered Korg SQ1 midi out no probs … no PSUs anywhere, but i have an older Korg MIDI KMT6 Thru box which has 6 outs and that needs a psu !

EDIT: and as explained elsewhere above, some devices don’t offer up the juice at all !!
