Ruben40 Posted September 28, 2013 Share Posted September 28, 2013 When i start the sdcard recording , the the reaction time of the m20d screen is getting very slow. During recording I also playback audio from the sdcard. That means when want to use e. g. the faders, the m20d needs some time to react.When i stop recording or stop audio playback, then everything is ok.My sdcard is class 10. That means simultanious sdcard recording and sdcard audio playback slows down the M20d screen refreshrate. You can see the effect, when you watch the recording time counter in der record menu.

jaminjimlp Posted September 28, 2013 Share Posted September 28, 2013 Try reloading the 1.20 update, it may not hurt to go ahead and download a fresh copy of it for doing that. mine sometimes seems a little slow to react to my touches on the screen I got a touch pen and that seems to work a little better but I have left the original screen cover on which could be my problem but I didn't want to take it off until I got a screen protector for it.

Ruben40 Posted September 29, 2013 Author Share Posted September 29, 2013 I use the latest 1.2 Firmware. I use a sandisk extreme sdxc 64GB class 10 45MB/s I made several tests and I think that I have noticed the reason for the slow screen reaction of the M20d. First of all. the ipad mixer app does not have this slow down problem !!! my test result: simultanious sdcard recording and an active sdcard mediaplayer slows down the M20d screen reaction You can see the effect when you look at the the recording clock in the record menu my test result: When I stop the sdcard mediaplayer instead of muting it, then the problem during recording seems to be gone. Could anybody test this behaviour ? Thank you. Quote Link to comment Share on other sites More sharing options...
linesixy Posted September 29, 2013 Share Posted September 29, 2013 Are you saying that you're playing back files from an SD card - and simultaneously recording onto an SD card? Didn't know this could be done (as there's only one SD card slot - I think). Interested to learn more about this. Quote Link to comment Share on other sites More sharing options...
Ruben40 Posted September 29, 2013 Author Share Posted September 29, 2013 Yes I mean playback(mediaplayer) and recording onto the same sdcard. Quote Link to comment Share on other sites More sharing options...
linesixy Posted September 29, 2013 Share Posted September 29, 2013 Cool. Didn't know that was possible. So are you simultaneously playing backing tracks on the media player... and then recording multi-track of each input channel and also recording the mediaplayer playback as well?

Digital-sound Posted October 1, 2013 Share Posted October 1, 2013 I wouldn't have thought that was possible either. Could explain why it is slow though. That is a bit to ask for. I just assumed it wasn't possible so when I set mine up I put my backing track on a USB stick, and my recording goes to the SD card. Maybe try that. And I have the wireless function too with a USB hub. So my wireless and media both go into the M20D USB port. Works well. Quote Link to comment Share on other sites More sharing options...
case67 Posted October 2, 2013 Share Posted October 2, 2013 Hi Digital-sound, what USB hub are you using? Thanks, Tom Quote Link to comment Share on other sites More sharing options...
Digital-sound Posted October 2, 2013 Share Posted October 2, 2013 I use the airport express set up. It comes with a sort of USB splitter. So you plug the USB-Ethernet adapter into the USB port on the M20D, and then the USB stick plugs into a littler "dongle" off of that. So it is a USB hub...sort of, but I don't think one that you would find. But I have read in other posts that USB hubs work, but best to get a powered one.

Ruben40 Posted October 5, 2013 Author Share Posted October 5, 2013 Very interesting. I also use the airport express setup with the ethernet-USB Adapter. But how can i use the Airport as USB hub? Can you describe your setup more detailed. Where should i plug my USB stick. Thanks Quote Link to comment Share on other sites More sharing options...
Digital-sound Posted October 6, 2013 Share Posted October 6, 2013 The Ethernet adapter I bought, has a USB port. It is very similar to the apple usb to ethernet adapter. I will look to see which brand I bought. I can't remember and I am away from my board until Monday. It looks similar to the apple one when I was trying to find it.

Ruben40 Posted October 6, 2013 Author Share Posted October 6, 2013 Ok. I use the apple Adapter and there is no usb connector. Think you for sharing your information. Quote Link to comment Share on other sites More sharing options...
Digital-sound Posted October 6, 2013 Share Posted October 6, 2013 I thought I saw it in the picture, but I will post back here tomorrow evening with the one I am using. Quote Link to comment Share on other sites More sharing options...
drmarkod Posted October 7, 2013 Share Posted October 7, 2013 Not sure if this is of any importance with the slowed response time, but you noted that you are using a 64 GB card. It appears to me that the max is 32 GB. From a page that lists compatibility of SD cards http://line6.com/support/page/kb/_/live-sound/stagescape-m20d-mixer/wifi-usb-adapter-sd-card-compatibility-an-r112 "The following SD cards are compatible with the M20D: Any class 10 SD card is compatible with the M20D. Only class 10 SD cards formatted as FAT32 are compatible. 32 GB maximum SD storage space" Quote Link to comment Share on other sites More sharing options...
Ruben40 Posted October 7, 2013 Author Share Posted October 7, 2013 Thank you for your answer! I made several test with different sdcards (32GB FAT32 class 10). The slow performance on the M20d screen remains. Now I'm pretty sure, that the reason for the slow performance is playing mp3 files from sdcard and simultanious recording on the same sdcard. Maybe a data bandwidth problem of the sdcard! I will test a new usb to ethernet adapter with an usb hub. Here I want to use an separate usb stick for playing back the mp3 files. Maybe this will solve the sdcard performance problem. Quote Link to comment Share on other sites More sharing options...
drmarkod Posted October 7, 2013 Share Posted October 7, 2013 How about using the Apple Airport Express and streaming the backing tracks from your iPad to the Airport Express, then into the M20d via 1/8 to 1/8 stereo patch cable? This would free the M20d from having to deal with the backing track altogether, except as a stereo input. Quote Link to comment Share on other sites More sharing options...
Digital-sound Posted October 8, 2013 Share Posted October 8, 2013 This is the USB to ethernet adapter I have. It is a Moshi. It allows me to plug a USB stick in it as well with my backing tracks, and plays and records no problem. http://www.moshimonde.com/product/usb-to-ethernet-adapter.aspx Quote Link to comment Share on other sites More sharing options...
Ruben40 Posted October 18, 2013 Author Share Posted October 18, 2013 I tried the Moshi ethernet adapter with a separate usb stick, but I still notice the low performance problem at the M20d screen during the playback of mediaplayer audiofiles from the usb-stick. My workaround is to stop the mediaplayer, when our show begins. Quote Link to comment Share on other sites More sharing options...
Digital-sound Posted October 21, 2013 Share Posted October 21, 2013 I guess that, or use an external media player. Too bad it doesn't work for you though. We all like to have less gear to bring and hookup! Quote Link to comment Share on other sites More sharing options...
JeffersteinVS Posted October 23, 2013 Share Posted October 23, 2013 I have the same issue. I also notice when you have ipads connected it slows down, We have a 6 piece band and use all 16 channels with dsp , we playback music from the SD card and record the show. Id love to have a CPU/RAM meter on the next update Quote Link to comment Share on other sites More sharing options...
Ruben40 Posted October 24, 2013 Author Share Posted October 24, 2013 You can use the recording time clock in the recording menu as CPU meter. If you see the clock digits stuttering, then you have the performance problem. Quote Link to comment Share on other sites More sharing options...
Ruben40 Posted November 13, 2013 Author Share Posted November 13, 2013 At our last gig i noticed again the slow performance at the M20d desk during recording the show. It's hard to make sound adjustments. This is very anoying. But strange: the performance on the iPad was without a problem. Here it was no problem to make sound adjustments with the faders. Could anybody confirm this Problem ? Quote Link to comment Share on other sites More sharing options...
