JM4 Looper - SD card problems

support@line6.com — Fri, 20 Nov 2009 22:28:30 GMT

Hello,

1) Be aware that you must first store your wav files to the unit, you cannot access wav files directly from the card.

2) Be sure your card is 1-2G in memory, and format the card to the FAT16 protocol using the directions here:

JM4 Looper snap crackle & pop

support@line6.com — Fri, 20 Nov 2009 17:13:37 GMT

Thanks for this input. However, the crackles are in the file once it's been mixed down to a WAV file on the JM4. Even listening to the WAV file on the JM4 demonstrates the problem. Its not related to the PC or the card reader.

But to be on the safe side, I tried a different SD card, a different card reader, and a different PC --Same problem. (Though I did wonder about the card reader and that's why I tried to narrow down the source of the problem.)

Chord Progressions

As you may already know, we do not have the chord progressions or tab of the songs that are built into the JM4 Looper. Joe's Jamblog looks to be the closest thing to what you are looking for.

JM4 stereo out vs speaker cabinet voiced out

support@line6.com — Wed, 18 Nov 2009 01:54:46 GMT

Thanks ,

It was a poorly asked question but thanks for the reply - I will marked it as answered.

Is it possible to switsh sounds using the switshes of the FM4?

support@line6.com — Mon, 16 Nov 2009 21:01:00 GMT

That's actually quite easy and straightforward (if you've read the manual): tap the right footswitch (the unlabeled one) three times until the display shows "guitar preset mode". In this mode, the left / 2nd from left (rec / play) footswitches select the previous / next guitar preset. Arrage your user bank accordingly and you're all set. Make sure you explore the other modes as well, because you can select (your own) pre-recorded loops via footswitch in the same manner and play them live. Excellent and lots of fun!

Downloads for JM4 Looper

Sorry it took me time to respond been in Fort Worth. I have taken your suggestion and sent in a question on potentially

in the future making such back tracks available both drums and other music tracks.

Would be great if you had popular tracks that you could sit in on and add your own flavor......now that would be awsome

Mixing down to a wave file

support@line6.com — Mon, 16 Nov 2009 19:37:19 GMT

Thanks for your reply... I did finally get the JM4 Looper to write a .wav file to the SD card. I just kept trying the format and then finally it just started working and it has been great. What I find produces better results is recording in stereo direct from the JM4 outputs to my BOSS 1150 digital recorder. The stereo file sounds so much better then the mixed down mono loop.

Thanks to everyone who replied.

Reversing Loops

support@line6.com — Wed, 11 Nov 2009 19:19:49 GMT

The JM4 does not offer the reverse loop feature.

It also does not offer an auto-record feature. (any "advanced" looper should have this feature for sure!)

It also lacks a redo feature (as in undo/then redo - again, any "advanced" looper should have this feature also.)

Also, it has a minimum loop time of about 2 seconds, which makes it very uninspiring for looping quick tap/slap backing rhythms with your acoustic guitar.

Also, if your primary instrument is acoustic guitar, you are limited to using the aux input mixed with vocals (to get a natural acoustic sound) which means you can't use any of the amp models, cool effects, or use any of the center control knobs on the unit as they are all designed to work with the electric guitar channel only.

That said, the New M9 Stompbox modeler has a looper with the reverse and undo/redo features.

It seems highly illogical for the JM4 which is marketed as a dedicated looper to lack these valuable features and then for the M9 which is marketed as a stompbox modeler to to include these features that the JM4 lacks.

Don't get me wrong-the JM4 is cool-the live backing tracks and effects are great, and the SD card functionality is convenient, but if you want a looper that is designed for live solo performance (which usually means acoustic guitar) there are others loopers out there that are better equipped for the gig.

I was super stoked when I bought mine, I use many other line 6 products and I assumed this would be the best looper available. Once I started exploring the features and discovering the limitations, I started encountering one disappointment after another-primarily those I mentioned above.

Hope this was helpful.

Good Luck!

Joe thanks for the assistance -

Sorry but Im a bit new to all of this so you'll have to be patient -

Its the step-by-step- idiots guide I need...

1 What does "green" "red" meant and how do I get Blues Red or Green

On the JM4 there is a "green" and "red" setting for each of the amp model settings (far left knob in the effects row). As you slowly turn the knob the LED display will say "Model: Clean Red", "Model: Clean Green", "Model: Twang Red", Model: Twang Green", etc. Its only there for a second or so so pay attention to the display. There is no LED light to show the color, its only indicated on the screen.
