Bangha Posted September 23, 2016 Share Posted September 23, 2016 Hi everyone, Just bought a JTV-59 and wanted to try workbench HD, but the software does not see my guitar. Running on a MacBook Pro, OS 10.11.4 I installed the monkey, updated everything. Connected the USB interface to the computer. Connected guitar via VDI to the USB interface. Connected 1/4 inch to guitar output. Interface is both lights solid green. Guitar volume is at 10. Modelling is off. Workbench HD does not see the guitar. Any ideas to help a workbenchless brother out? Thanks! Quote Link to comment Share on other sites More sharing options...
silverhead Posted September 23, 2016 Share Posted September 23, 2016 The only thing you didn't mention is power. Is your JTV battery fully charged and in place? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 23, 2016 Share Posted September 23, 2016 Battery in the JTV, and the 1/4" cable ought to be a TRS plug. Leave the other side of the 1/4" open, the idea is to simply engage the battery. Both LED's on the interface are green, so from a hardware stand point it's good. Volume and tone to 10, good. The JTV has Flash v2.21? Are you running your Mac Book on battery or power adapter into an outlet? Is Workbech HD already open when you plug everything else in?

Bangha Posted September 24, 2016 Author Share Posted September 24, 2016 Thanks for your help everyone, everything was the way it was meant to for workbench to work. In the end it took three reboots and a USB port switch for the interface to finally get things working. Thanks for the pointers! Quote Link to comment Share on other sites More sharing options...
theronnyjones Posted October 15, 2016 Share Posted October 15, 2016 I'm having the same issue but on a new iMac. Also, Line Monkey want's to continuously update. I've run the update at least 5 times and it's still doing it. I just got this guitar yesterday and so far I've had several issues with it. It's brand new. :( Workbench worked fine last night. Now I get nothing. Quote Link to comment Share on other sites More sharing options...
psarkissian Posted October 17, 2016 Share Posted October 17, 2016 See my prior post. If your iMac is a laptop, use the wall adapter, not battery. Hook it all up first, then open Workbench. Quote Link to comment Share on other sites More sharing options...
cruisinon2 Posted October 17, 2016 Share Posted October 17, 2016 I've used a Macbook pro running on the battery with Workbench countless times without an issue, as recently as yesterday. Aside from the possibility of running out of juice entirely, how could this possibly make a difference one way or the other? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted October 17, 2016 Share Posted October 17, 2016 If there is a sag in the USB line during updates and such. Need to keep the USB 5-Volt line from sagging during updates. Some batteries run down quick. The 1/4" jack battery engagement on the JTV helps, but the battery should be at 4-LED full charge first.
