Hey there, thanks for taking the time to check out my listing! This is for a Rolls RP93S switcher and Rocktron MIDIMate. I'm selling these as a bundle because there was some minot modifications made, I can't remember where, for the MIDIMate to phantom power through the 5 pin MIDI cable, that means you don't have to run power out to the front by your foot for the MIDIMate. When you connect the cable, power on the MIDIMate is powered. I used this on my amp/effect rig back in the 2010s, it works really good and you can program the text label so you are not remembering by number, see photos. This is a very nice switching system if you don't want to shell out for the newer stuff. The RP93S has 4 loops to insert effects, 4 relay switches, these can be programmed to be on/off per MIDI program. There is also MIDI thru to send program change to your other rack units. This also includes a 20 foot 5 pin MIDI cable. There are lots of DIN cables that only have 3 pins connected. Buyer pays shipping, I only ship to the US mainland.
