MIDI Thru

Testing/Troubleshooting
1

Please ignore my incompetence, I’m new to MIDI..

Am I correct to assume that I can connect my MIDI

keyboard to the MIDI thru port on the MIDIBox Plus

and thus be able to use my Keyboard aswell as the MIDIBox Plus at the same time? (Thus I dont have to pull out one device to use the other on the MIDI in on the computer..?) If not, what is the MIDI Thru used for?

I have modified the Dave wheelers schematic to incorporate the MIDI Thru.. Is it ok to have both the

MIDI In aswell as the MIDI thru connected to the Rx pin on the PIC at the same time?

Many regards,

Rob  :)

Hi Rob

> what is the MIDI Thru used for?

…“Some instruments have a third MIDI jack labeled “Thru”. This is used as if it were an OUT jack, and therefore you attach a THRU jack only to another instrument’s IN jack. In fact, the THRU jack is exactly like the OUT jack with one important difference. Any signals that the instrument itself creates (or modifies) are sent out its MIDI OUT jack but not the MIDI THRU jack. Think of the THRU jack as a stream-lined, unprocessed MIDI OUT jack.”…

Thanks for the informative link, Lemonhorse! :slight_smile:

Rob: if you don’t want to use the snap function of the MIDIbox, just enable the integrated MIDI merger and wire the cables like shown here:
