I tried my R07 for the first time last night with great results. I was open taping The Ike Willis Project and Micki Free. The music ranged from Micki's LOUD Jimi Hendrix, Stevie Ray Vaughn, Peter Green very (very) loud music, to Ike's pretty darn loud Zappa like music. Both artists had impressive sets. The deck handled it all without any issues. In fact I had forgotten I set the deck to record a second track at lower dB, and that track was very very low. I used AT 853>Naiant Pipsqueak>Roland R07.
Because as stated above I was open taping using the MixPre6 with 3 sets of mics, I made sure to move levels and play around. I controlled the deck mainly from my phone to get a feel for that. I changed levels quite a bit and had no zipper effect at all. Maybe this was due to the very loud volume, but nothing audible at all.
I had no trouble at all with the Bluetooth, but I believe that it is meant to be used a certain way. If you lock the deck (on the deck with the power button in lock position) which I did, the remote from the phone will still control the levels as well as record, stop, start and all. After doing whatever I need to do, I either close the app or move off the app to texting camera or whatever, so I do not accidentally hit stop or change levels. At this point the app releases the deck and I think that is a protective measure. If I want to check levels later or make changes later on, I press the app and a search button appears, I press that button, the deck appears, I press that and it instantly connects, I hit the go back arrow and have functionality once again. It all takes just a few seconds. In my usage last night I thought that was great for my intended use, because I can stuff the deck and Pipsqueak or my UGLY into my pocket locked and use my phone to make changes without any fear of shoving the phone in my pocket and screwing anything up. It felt to me as if this was thought through in the design to allow the best usage and protection with the remote control by phone. As for the Bluetooth setting on the deck, once you activate it within the menu, it remains on always, until you disable it. So you can power off the deck and the next time you turn it on, the Bluetooth light will light showing you that you can connect to your phone app at any time you choose. This could be a battery drain, but you could turn it off if you do not plan to use the remote. I had 2 rechargeable LADDA (Ikea) batteries in the deck, had it on and/or running from 7pm til just after midnight and showed nearly full battery after. Normally I use and external to be safe, and certainly if I shove it in a pocket that is an easy option, but It will not be necessary unless it is a
marathon.
