I actually do both. When setting stuff up I typically use a controller that can transmit as many CCs as I want. But, while in use, my ability to send CCs is limited. However, I did not realize TF could XMT PCs. Does it have to be same PC on same channel? I thought there was no "midi thru" capability on multiple channels. In other words: can TF transmit a different PC on a different channel than it is receiving? Otherwise, they'd all have to line up: same PC o same channel on both devices..
