Miditech Midi Thru 4 /Filter

After some time of use, I have to tell that often one of my 4 midi devices connected to this box loose communication. My midi/clock sender is an Elektron Digitone and the device and the port loosing connection is completely random. Useful device if you use less then 4 midi devices.
The building quality is not the best (plastic) but it's compact and lightweight.

You can't modulate different cc parameters on different synths on different midi channels at the same time with Miditech Midi Thru 4 /Filter.

Bought this to detune a synth from another synth by one octave using the Transpose function. The manual says it can transpose +/- 2 octaves. After months of trying intermittently, the manufacturer responded to one of my messages, and it turns out the manual was wrong. The manual was quickly updated, but updating a manual doesn't make my device work.

Money gone and another useless plastic brick.
