This needs an iPhone app for a host of reasons. If battery runs out on ipad then at least I’d have a back up with my phone or someone else’s phone. Since I’m only running a few channels most of the time I really don’t need a big screen to manage everything. In addition to having the virtual knobs to change the EQ it would be really nice to be able to add frequency points on the EQ curve to pinpoint the exact frequency I want to change.The ability to select which effects I want for each effect channel would be great. There are two effects I like but they are both in the same effect slot so I can’t use them both at the same time. I love being able to label all the tracks however it would be nice to be able to clear all labels at once rather than one at a time to reset them.Faders are really touchy. When I grab a fader to move up or down in volume the fader jumps to my finger right away sometimes causing the volume to get loud before I can change it. Would be great if the fader didn’t move upon touching it and only move when I actually slide my finger.There is a lot of good stuff here but I don’t think there has been an update to this app in a over a year. Doesn’t make me feel confident that anything is going to get any better which is a shame. I love the portability of this unit and the recordings sound really good and have been a great benefit.

Basic functionality is fine but it’s missing so much:• A paste function to duplicated settings from channel to channel• Gain and compression controls in app• iPhone version for quick changes and transport controls quick at hand• More track colors or a rgb selector• Ability to pair stereo tracks• Ability to label tracks with namesI’m sure there is more. As said, it’s basic functionality is fine, it’s quick to acquire via bluetooth, no connections issues or drop outs so far, graphics are crisp and clean. etc.Please consider updating more. Since this is the only way to use the full function of this unit, seems like the whole app was an afterthought. I owned the L-20 and L-12, the unit is sound and works great, proven, but the rack version is lacking in more ways that just to get it into a rack.

In July 2022 I’m having no trouble controlling my L20 with this app. Obviously, it is wonderful to be able to check the mix from the audience position. It’s been a while since the app has been updated, so I’m hoping that, in addition to an iPhone version, there are some other features on the way. I would especially like some kind of RTA functionality with an EQ with many more bands than are currently available, so that I can “ring out” mics/monitors before a show, or better yet build in some tweakable feedback removal. This is a hardware/software system with absolutely massive potential. I have recommended and demonstrated it to many friends and I hope that Zoom continue to develop it for many years!

I’ve been using this regularly for several months now. As a device, I like it. However as an app, it is severely limited as an iPad only app. I don’t use iPads on stage and I despise the fact that I have to bring along an iPad for gigs. The big Yamaha boards have been iPhone compatible for years and is a great way to control a personal mix. If I could use the tiny supercomputer in my pocket to control this thing instead of a larger iPad I’d easily give the app 4 stars. Give me more better reverb options on the FX channel and I might even make it 5 stars.
