Does it really annoy you to wait for 20-30 seconds for the machine to warm
up? I don't think this is actually a technical problem. Please put away your
soldering iron and stop frightening us... ;-) I must admit 20-30 seconds is
a bit long at a 'warm boot', but I don't think it's a technical problem.

Tip of the day: Turn on your JP8 half an hour before a recording session or
performance to give the JP some time to warm up inside as well. Before
playing your first note, hit the auto-tune button. If you don't trust your
JP to be tuned, check it earlier and/or keep a frequency counter/tuner
connected to one of the ouputs on the machine that is not routed to the
mixer. This way you can check the tonal stability of the unit every five
minutes...if you like...
