USB Powered - Warbling Noise

Hi

Hooking my JP-08 up with the USB cable produces a type of alien warbling sound in my mixer. Disconnect the USB (and run on batteries) and all is fine.

Anyone come across this problem?

I need the usb cable to send program patch changes form my Macbook (via Logic) to the JP-08.

Thanks in advance.

Common problem. If you need USB connected, then (as long as you’re on a recent firmware version) you can force battery power even when USB connected. To do this each time you boot, hold down the ‘Patch Preset’ button whilst powering on.

Thanks. I don't think that solves my problem though. I have it on battery power. It's when I plug the usb lead in from the Macbook, which I need for the program changes.

Still the problem can be caused simply by having the Boutique connected to the computer. When connecting the unit to the wall with some usb charger all the buzzing and humming should go away. Regarding sending patch changes to the computer, it should be still possible by using some oldschool usb midi interface, but obviously then it's not possible to use midi ports for keyboard playing.
It seems to be quite a common problem nowadays, that different usb powered devices tend to generate unwanted sound while being connected to the computer and not do it on wall power.

I thought about that (usb to midi) but yes, I have the keyboard into the midi in. I'll try the patch preset option. Do I hold down any particular one of the eight or will any do?

Apologies - I meant Patch Preset 1 (the ninth button along). Hold it while turning off and on. This WILL solve your problem as long as the unit is NOT still on the original firmware. You can check your firmware version by holding down Patch Number 8 button while powering on - and let us know what lights you see. Feel free to PM me and I’ll help you out.

My solution was to drive the Boutiques from iPhone chargers connected to the mains, use Regular 5-pin MIDI cables to control the Boutiques and use the analog outputs into the DAW. That was the only way to get a reasonably clean audio. Also I added a noise gate on every track to silence the Boutiques when they were not playing.
