I had the unpleasant surprise to discover this after i bought the unit.
It won't drive a TR808 or any machine using sync24 through a doepfer MSY2, even if the doepfer is powered.
Also the midi won't pass thru if you plan to use a midi thru such as the quadra thru by midi solutions.
3v is today's standard but the old machine need at least 5V.
For example my AMT8 from early 2000 is sending a 7 to 8v.
So people planning to use it this way be warned.
We contacted the company about this going thru french distribution and for the moment there is not fix and no real answer.
this is also the case with the other midi interface by Iconnectivity.
