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?

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.
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.
