Time Stretch Won’t Work A Second Time

Q:I made an 8-bar loop of a Drum track, then sped it up from 100 bpm to 110 bpm. After I recorded a guitar track, it felt too fast, so I tried to slow everything down to 105 bpm. The JM4 locked me out of changing the tempo again. Why is that?

A:The Time Stretch feature can only work on one mono track at a time. Since the JM4 Drum track is being processed to match your recorded guitar track, you can’t re-adjust the tempo of the ‘live’ drums and recorded guitar at the same time. To change the tempo again, you could do a Mixdown, a Clear All, then load your Mix to start fresh. This is one reason why we suggest you determine your tempo before you record.

Loop Overdub Volume

Q:I like to overdub several harmony guitars to a loop, but when I let it roll for 3 or 4 passes my backing track loses volume. Why is this happening?

A:Your Recorder Overdub Volume is probably set to something less than 100%, so your volume decreases every time your track loops in Overdub mode. Press the Drums/ Song button twice and navigate to the Recorder Overdub menu item, then press the R

Arrow to select it. Use the wheel to set your Volume to 100% and it won’t decrease.

Quick Capture

Q: The JM4 silkscreen reads Rec+Undo = Quick Capture; why doesn’t this work?

A:To engage Quick Capture, you must first step on Undo, then the Record switch. We’re sorry we didn’t make this clear in the Pilot’s Handbook.

Can’t Overdub To A Time Stretched Recording

	Q: I recorded a simple rhythm guitar track, then I did a Time Stretch to slow it down.
A•2	When I tried to overdub a lead guitar part, I was locked out of doing so. Why?

A:The Time Stretch setting you applied to your guitar track has ‘claimed’ the DSP processing, which can only work on one track at a time. Since the Time Stretch is still active, you must first Save your recording at the new tempo, then do a Clear All. At that point, simply recall your saved recording, then you can overdub guitar as usual.
