I was intrigued with the idea of wireless MIDI when I first saw the Widi Master. I am personally fed up with cables laid out on the staging floor, inviting me to trip and take the token header. But that aside, I found two sets of Widi Masters allow my Roland digital piano and Yamaha TG to communicate just as well as if they were cabled, with absolutely NO latency issues. The only problem I have encountered is that the MIDI signal has shut down a few times during performance. I thought it might be an input issue of over modulation. The tech for Widi Master suggested that may not be the case and upgrading the firmware may be the answer. I'm on vacation presently, but when I get back, that's what I'll try. But no matter what happens, I still really like the WIDI Master to exorcise another cable to trip over.....go get yours!!
So I play guitar in a band called the afters, for our regular set I use the WIDI in the back of my line6 Helix to receive program change messages so that my pedalboard changes patches for each song but also changes presets for each section of the song exactly on time! Even if I’m roaming the stage somewhere or down on a catwalk Ableton tell my pedalboard what to do!! On smaller/acoustic shows where we don’t bring a drummer(who would normally control Ableton) I have an acoustic/vocal patch built in my Helix that can select tracks, play/stop and use my volume pedal to mute the tracks just in case we get off the click. I used to have to run a 50’ midi cable from the drum riser to downstage left but now I just leave my WIDI plugged in and I’m set!
