  1. Has anyone else tested this on iOS14.x? I've been holding off updating for months now....
  2. Has anybody used the backup/restore feature sucessfully? I just reinstalled the latest firmware, to see if it would fix some of the issues I've been having. Earlier on I saved my presets to my SD card, so I knew I'd be able to restore this file after the software update. I had one Setup file which I'd been working on for my band. It was definitely saved to the unit prior to the backup being created. The file is there on the SD card (BackupFile.bin), but after restoring it, my list of Setups is empty. Looks like either the backup or the restore has failed. Is there some other step needed to get the backed-up Setups into the list? Anyone else faced the same problem?
  3. Well, here's the report from last night's gig: Sad to say, it let me down big-time :( I tried ringing out channels before the gig, but I had lots of problems despite this: Acoustic guitar - fed back every time I left the strings unmuted. Percussion (basically a bass drum and other bits being picked up by a PZM boundary mic). Lots of low-frequency feedback that was loud and very obviously monotonic (ie surely easy for an algorithm to identify). During soundcheck I even let this run solo'd at very loud levels, and there was no sign of the feedback being notched out at all. Vocal mics - we had a couple of cabaret-style singers performing before us. Both these guys were standing a bit closer to the speakers (LD MAUI 11 Line Arrays) than was ideal, and they both got occasional bursts of feedback, which only stopped when they moved away. No apparent difference vs using a standard "dumb" analogue desk. Due to all of the above I had to keep the overall level a lot lower than I would normally set it, which detracted from the gig quite a bit. Also the iPad connection was refusing to work, hence I was powerless to help when the other guys were on stage. All in all, the bottom line for me is that the three main USPs of this mixer are just not working properly, i.e.: Feedback reduction Multitrack recording Wireless mixing. I'm just going to take it back to the shop and ask for a replacement unit. There are too many faults here for me to want to start troubleshooting them individually with Line6 support. I'm still convinced this is the best solution out there for what I need though. I just hope the replacement unit is better!
  4. Hi all Have been away for a few days, hence not checking in to this thread. I've only used the M20 for one gig so far. We used the Headway pickup for the fiddle, and didn't push the volumes. I think I kept out of the feedback zone using that method, and hence didn't really try the FBS. There was one section in the gig when we invite audience members to come up and sing a few lines. Typically this means people with no mic technique (ie not close enough), and with fairly weak voices. I had to push the volume up during that section, but feedback started to creep in, hence I couldn't get it as loud as I would have wanted. So, from that I conclude that the FBS wasn't really doing anything. We have another gig tonight in a larger venue, so levels will probably be higher. No audience participation for this one, but I'll be keeping my fingers crossed we get through it.... From the other responses it seems this feature either works very well, or not at all. I wonder what random factor is at work here? One thing I do know - I'll be raising a ticket and requesting a replacement desk as soon as I have a clear time window with no gigs.
  5. I thought there were 12 frequencies per channel, not over the whole mix? Anyway, I've tested this in the simplest possible way - with a single SM58 and one speaker. It feeds back pretty much unrestrained. I might see at most three or four frequencies appearing (the red lines), but they don't seem to make any difference to the feedback that's occuring.
  6. I guess nobody has any ideas on this? I have a gig on Saturday, so this'll be the first chance to try FBS in a real performance setting. Will see how it goes and report back. For this gig we'll be using a Headway Band pickup on the fiddle instead, as it's more feedback-resistant.
  7. Unfortunately their opening hours coincide exactly with my work hours (understandable I guess), which means that's the one time of day I won't be able to have the unit in front of me to test out any suggestions. :wacko: Can I submit a ticket online?
  8. Hi Arne I'm trying to replay the recordings as soon as they've been created. So, nothing has changed in the setup between recording and playback. I always use "record inputs and main mix". The recording path is correct, and I've not disconnected anything prior to pressing stop. In short, I've done everything according to the instructions. It simply isn't working
  9. Hi Arne Yep, I understand the rationale for traditional mixers, but that's my point - the M20 isn't a traditional mixer! It creates an entirely new use case - ie soundchecking by recording all channels, and then tweaking the settings. It's only during that specific use case that you'd want solo functionality on the main outputs - not in real-time performance mode. This is the use case in its simplest form: I'm a musician in the band, I'm also running sound. The desk is placed next to me on stage. To soundcheck, I record a quick capture of the whole band. I then grab an iPad and walk out into the venue to tweak the sound. First thing I want to do is mute everything except the percussion, and tweak that. Then I might mute the perc and tweak the two guitars, listening to each in isolation, and then the two together. Then I put the drums back in and adjust accordingly etc etc. To achieve this, I need to individually mute all channels, and then selectively unmute and re-mute as I go. If I want to quickly flip between the whole mix and a single channel, I have a lot of buttons to press. Remember, the Mute All buttons aren't available on the app, so I don't have easy access to those. With a traditional mixer and dedicated sound man, you'd do the above the old way - ie by asking individual musicians to play one at a time. With the M20, we don't have to do that any more! So, my suggestion would be to have an option to apply solo buttons to the main mix, but ONLY when playing back a recording (Quick Capture or multitrack), it would NOT apply when in normal performance mode, to avoid the scenario you described above with traditional mixers
  10. Okay, I've just had another try. Not looking good.... I created a new setup with just one acoustic guitar going direct to input 13. Same problem. I tried creating a new folder on the SD card, and I also tried recording to a USB hard drive. It was recognised, and I could create a folder there too, but had the same problem with blank recorded files. So, it seems this isn't specific to SD cards - any external storage media seems to have the same issue. Quick Capture works flawlessly with the same settings, so I know it's not user error...
  11. Hi I was wondering - is there a way to have the solo buttons operate on the main outputs (not just the headphone jack)? Last night I was using Quick Capture & iPad to do a mix, and I wanted to listen to tracks individually whilst tweaking. It seems the solo buttons don't do this, at least not by default. Instead, I muted all the channels individually and unmuted the channel I wanted, but this seems quite cumbersome. Also it struck me as odd that the Mute Mics and Mute All buttons aren't replicated on the app. Is there any reason for this? Thanks Keef
  12. Nothing new to add to this yet, but I just wanted to add myself to the list of people having this issue. I wasted a lot of time last night (first time using the M20 with the full PA setup), before giving up in frustration. I hope the L6 SW guys are working hard on finding a fix for this! I'll try some of the suggestions in this thread when I get a chance, and will report back...
  13. Hi all! I had my first rehearsal using the M20 last night. It's a four-piece folk/acoustic lineup. We're using two LD MAUI11 compact line arrays for speakers, and overall the sound was excellent. One particular problem I had was with the feedback reduction. We use a DPA 4099 clip-on condenser mic on the violin, which can sometimes be a challenge with feedback. In the past I've successfully notched out the worst frequency with the parametric EQ on a Bose T1 mixer, but I was looking forward to seeing how much better the automatic reduction would be on the M20. Sadly, it completely failed to deliver. I auto-trimmed the input gain, and then cranked up the master. Very loud feedback ensued, at multiple frequencies. The FBS was on, and I tried resetting it and switching between vocal and universal setting. After trying for some time, it hadn't found a single frequency. My ears did though- it was very loud, with very easily discernible individual frequencies. A bit later it did pick out a couple of lower frequencies (ie the red lines appeared on the chart), but it made no noticeable difference to the feedback. As it stands, this renders the DPA mic completely unusable, which is hard to take since the per-channel FBS was the main reason I went with the M20 in the first place. I also tried this same operation earlier with an AER acoustic amp and an SM58 with basically the same result. No apparent attempt from the M20 to cancel any feedback frequencies. Am I missing something? Is anyone else having problems or could my unit be faulty? It has the latest firmware. Thanks Keef
