We have heard and learned a lot about humming spark amps in the last time. If you can make a video it could help us to help you.

@dhbailey Thank you for taking time to respond. The reference tuner was set to 440hz as well as an iPad app. I updated the Spark's firmware and did a factory reset. The spark is now consistent with other tuners I have. this may get very fun!

@niall-clancy what form Niall? I have to fill in my email and order number to check on mine. Just ordered, on the 31st July, when I was drunk one night 😬

@dhbailey Yup, my point exactly. The number is rubbish. Take it off I say.

@dhbailey Sorta my experience with modeling in a live situation in the past. I call it the "hi-fi" effect in that you dial in this tone that sounds great, just like the record or whatever, in your home or studio but take that out into a live situation and you get buried in the mix. Usually because the mids have been so scooped and the highs are being lost to the cymbals and keys and horns and the bottom end to the bass and the guitar gets lost. The old story about Joe Walsh in the studio and dialing in his tone and someone their told him that it sounded HORRIBLE and said wait until they played and with the full band it sounded just right sitting in the mix. I'd probably mic it in a live situation but again not something I'd probably ever do with an electric.

@dhbailey Congrats, my unit will arrive Tuesday also... Plan on buying my wife a new Ipad so I can use her old Ipad as a dedicated tablet (her battery is dying). @domdv71 Any updates Pulling for you, I order my in Feb also. I had to contact customer service to get ship out. I think it was lost somewhere in the warehouse.

@elgrantimo64 To some extent I have. Seems to be taking program change commands from the controlling app just fine. Given that they reference the same chart as for BIAS FX 1 Mobile, I imagine one's patches have to be within the currect bank -- I can work with that.

Just received my Spark really pleased with it but it did have the hum problem. I am in the uk and have a backgrounders in electronics. The noise goes away when you touch the strings contacted support they asked me to shoot a video. I found an alternative grounded supply from Batt Dept £13.99 it is the same power supply as used by Asus laptop U32U-RX019V 19V 3.4A 65W (be careful as there are more powerful adaptors with similar connectors)

Do one of the following: Connect the USB cable from the keyboard to your computer. Connect the MIDI Out port to a MIDI In port on a MIDI interface, and connect the MIDI In port on the keyboard to a MIDI Out port on the MIDI interface using MIDI cables. Connect the MIDI interface to your computer.

This is one of our favorite videos by our friend Jeff, it has tips and tricks to help MainStage run at its best! https://youtu.be/otKMaHrYqr8 Run MainStage in Edit mode rather than Perform mode, and see if Edit mode is less CPU-intensive for you. Run MainStage in low-resolution mode to minimize the impact on system performance: right-click on the MainStage application and select "Get Info". Then check the "Open in Low Resolution" checkbox. Disable the "Perform in Full Screen" option: Preferences > Display > Performance. Set your buffer to 256 or higher: Preferences > Audio > Advanced Settings > IO Buffer Size. Also check the "I/O Safety Buffer". Turn off Auto Save: Preferences > General > Autosaving > Never. Keep your desktop clean! https://computers.tutsplus.com/tutorials/why-you-shouldnt-store-files-on-the-desktop--cms-21721 Turn off any icons running in your Mac's top menu bar. WiFi, Bluetooth, DropBox, etc can all eat away at available CPU and RAM. Keep your concert files from having too many patches. Every loaded patch consumes both RAM and CPU. Just keep the layered patches you are currently using. You can always export patches from MainStage, and load them back when needed. https://support.apple.com/kb/PH13627?locale=en_US Keep your audio levels from clipping, as it can cause CPU spikes and dropouts.

On iOS, the built-in Voice Memo app can capture perfectly fine audio, and you can improve it even further—just not within the app itself. Instead, head to Settings > Voice Memos > Audio Quality and change the quality to Lossless.

There're two Bluetooth scenarios you need to connect through the Spark Amp , one is to pair it with your iOS devices, the other is to connect it with the Spark Amp app. To pair Spark Amp with your iOS device: On your iPhone/iPAD, go to Settings > Privacy> Bluetooth and enable Spark Amp app. 2.Go to Settings>Bluetooth and enable Bluetooth, stay on this screen until you see Spark 40 Audio is detected under My Devices. Tap Spark 40 Audio to pair. To pair Spark Amp with Spark Amp app on your iOS device: Download Spark Amp App at: https://apps.apple.com/us/app/spark-amp/id1457653921 Launch the app and connect it with Spark Amp. Click on the top left setting icon to enter the menu, you can check firmware version and serial number under Hardware Settings.

@chrisedge I am happy to report that this morning I received an update email from PG that shows my amp has finally shipped -- I have an actual tracking number and checking with UPS I see that the package is actually in the possession of UPS and on its way! I just hope that people who ordered before me are also getting valid tracking numbers!

@dhbailey I forgot to add that I actually have gotten a tracking number and have checked and UPS actually have the package in their possession, so I finally believe it will really get here!

@r_koby I am hoping that as they get the manufacturing and shipping problems resolved, PG will be able to devote more time to the app, hopefully adding more effects and possibly rolling much of the BiasFX software into the app. I would even be willing to pay some for an increase in the number of pedals, the ability to change the order of pedals, and the addition of the use of footswitches to control the app. It would be wonderful to be able to use the AirTurn 4-switch bluetooth unit to control the app, and to place switches for the 4 presets on the amp into the app so that we could use a footswitch through the app to change between the presets with the tap of a foot. All that is possible in future updates to the app. It will be interesting to see what sort of marketing they offer for adding more modules to the app.

@cmcwillieb only if the computer is turned on. People have reported that just making the connection solves the hum problem. My amp is on its way (finally) but I've already purchased a grounded power supply so I'll be able to start using it as soon as it arrives without having to use the USB connection. I also purchased a battery pack which is most likely the way I'll be powering it most of the time, so there won't be a grounding issue at all.

@peter-moore350 Thanks for letting us know that the factory reset solved your problem!

@bk I just hope that people who ordered before us are starting to get tracking numbers and confirmed shipping!
