Hello, I saw a post back in 2016 asking if it is possible to add MIDI foot switch to Pocket POD. (Here is the link to related post https://line6.com/support/topic/19104-pocket-pod-midi-footswitch/) In the below link you may see my solution for controlling Pocket POD using Raspberry Pi W as a MIDI controller. This video shows Pocket POD connection with Raspberry Pi Zero W https://www.youtube.com/watch?v=U2I2CBarQQ8 Program runs on Raspberry Pi Zero W. It is also working on Raspberry Pi Model B. You may connect your cell phone or tablet to Raspberry Pi to change presets etc. on Pocket POD. Also I have added buttons and Pots to Raspberry Pi via IO Pins. Therefore I can control Pocket POD with hardwired buttons and potentiometers. I modified a volume pedal to add wah wah control on Pocket POD. Here is the method Volume pedal pot ---> MCP3008 (ADC) ---> Raspberry Pi(running PD) -----(MIDI Control Commands) ---> Pocket POD * Only OTG cable required to connect both devices * At the end of the video I tried Wah Wah with tablet's motion sensor. I forgot my tablet does not have motion sensor :). But it works with my phone. Shake your phone and you get Wah Wah effect.

I think I've discovered perhaps why sometimes the iPad app just won't connect to the m20d Stagescape at all, maybe..would love to hear if anyone else has experienced similar issue to confirm my findings. Here's the usual scenario, and it happened again about two weeks ago: Mixer is already setup and on etc, I do some sound checks, i start recording, then I try connecting ipad but it just gets stuck searching or something and can't connect to it. I try everything like rebooting iPAD a couple times, making sure iPAD is connected to the same wifi hotspot. The StageScape is connected by WIRED ETHERNET (via USB ethernet dongle) to a good powerful 3 antenna wifi access point, when it does connect usually works fine close and far also. So I tried disconnecting from wifi network, reconnecting, all kinds of things to no avail. I even tried removing power from the Wifi Access point and rebooting the wifi router and then reconnecting ipad and trying to reconnect to the Stagescape with the ipad app and still the exact same thing. Nothing I tried worked. I ended up having to stand up (yea sucked no tall stool available and m20d was up kinda high) for an hour or more when I already was feeling light-headed that day so wasn't fun at all, the remote control was the reason to get that m20d so I really hope we can improve on these connection issues. Interestingly and luckily the recording ran out of SDCARD space right when live event finished, I haven't had a chance to look at the files, I'm hoping they weren't corrupted due to having run out of space while recording. Now I think what would have FIXED my issue, is REBOOTING the m20d Stagescape. Many times that's what I do if I have connection issues but unfortunately sometimes I don't have time to mess with the iPAD first so I get the audio done quick and then if event is already underway I can't really "Reboot" the Stagescape to fix iPAD connection issues. What I think is happening is that I'm guessing that sometimes there's a glitch and when the M20D is Booting it does not get a PROPER IP or something, so during that bootup process either the router wasn't ready to hand-out or the Stagescape glitched somehow in grabbing it via dhcp, anyway somekind of network glitch results in the Stagescape not getting a proper network connection on bootup. BUT there should be a way for us to RESET the NETWORKING on the Stagescape without having to reboot the mixer completely. Is there any info panel anywhere that will show us more detailed networking information on the Stagescape? It would be very useful for diagnosing. I'm thining though that likely the current firmware doesn't provide a good way to reset the networking and it might only happen properly by rebooting the stagescape. Has anyone had similar experience where they could not connect to the Stagescape from the ipad app until they REBOOTED the mixer? I'm hoping this can be fixed in a firmware update where we can have a method to tell mixer to try and 'renew' IP ADDRESS or reset network or something like that without requiring a reboot to clear its brains. I do recommend to everyone though to ditch any of the USB wifi dongles and just connect a good wifi access point to the stagescape via USB ethernet. I tried with USB wifi dongles but its just much better with wifi router. If we can get some feature to reset networking on stagescape etc I think it will really help establishing successful remote connection if it fails on first try. Otherwise if somehow there's a proper way to reset the m20d networking without rebooting, that I've missed, I'd love to know, thanks! (maybe unplugging USB ethernet dongle and plugging it back in? I can't remember if I tried that or if I just unpowered the wifi router or temporarily unplugged cat5e ethernet cable)
