Hi everyone
I purchased a new laptop to play my midi's at gigs.
The problem that I am having is that the P.A. is only receiving the left channel from the head phone jack from the laptop
If I connect a set of stereo head phones to the head phone jack, I hear both channels fine.
I have purchased three lots of stereo and mono jack leads and tried all sorts of combinations and connections and adapters and still with no output from the right channel into the P.A.
The connections I'm using are.. a stereo head phone jack lead from the laptop and a jack plug (stereo or mono) into the P.A.
What I have done to get me by is to Pan "all channels" to the left in the laptop and in Virtual Sound Canvas (what else can I do)
This one has got me...if anybody has any clues it would be very much appreciated
Regards
Steve

I know this may sound stupid.....
But have you swapped the input on your PA.... used different sockets as there could be a problem with the stereo channel on the PA....
But I guess you have tried that.... Silly me.

I'm curious as to what sort of laptop you have, that has a good enough soundcard, that you don't need to use an external sound module. When I bought my new computer, I had to have a desktop, so that I could have my XG soundcard/daughterboard fitted.

Hi Ziggy I think this has been run over before. When I was using a laptop I installed the Roland VSC MP1. It's a virtual soundcard but provides excellent performance,with top class Roland sounds. Information available from the Roland site edirol.comYou can googlesearch for the software,it retails at less than 50 Uk Pounds. Hope this helps. |

Hi Stevie
Concerning your problem.
1. When going into your desk you should use stereo jacks (2) left and right.
BUT
2. If you have been using 1 stereo jack, gently remove it from the input socket to the first ring on the jack.
See what happens.

Having the Xg soundcard, I'm not into these virtual soundcard, but I'm having my son's lappie off him when he replaces it, so I'll look into that. Cheers. |

Hi there Steve, We use a stereo split cable (2 mono jacks) into two separate mono inputs in the desk. Partial pan right and left (about 80%). You could try getting hold of a hi-fi cable which has a mini stereo jack on one end, and two separate RCA plugs on the other end (normally red and white). We convert the RCA plugs to 1/4" mono jack plugs (either by using an RCA to 1/4" adaptor, or just cutting off the RCAs and replacing them with mono jack plugs. Hope this helps - you can mail me if you need more info. Cheers Jane  |

I use a laptop to play midi files...and a Yamaha QY700. I can load songs into the Yamaha and let it play itself, or I can use the laptop to play the QY700...with the QY700 acting as a sound module. The software sequencer I use is called ShowPlay. It is specifically designed for live midi performers. Can play midis, wav, MP3 files. Tempo/key changes on the fly...save changes...swap voices....too much to list here....all while midi is running. Can run up to 16 different sound modules simultaneously....Karoake/Text lyrics....Excellent software sequencer for live gigs

Get a stereo headphone lead and terminate 2 mono jacks on to it .Conversions jacks can cause cut out problems with extra weight on the circuit board.
Or even better is to splice a stereo lead with 2 mono jacks onto a stereo head phone lead.Solder and tape the joints.
I assume your PA is mono ?

I run all my Midi's in Mono (each channel Centre) Don't really see a need for Stereo Midi Files in a live situation.

Hi Thingyy
If ever you decide to come over to OZ, I'll be there the airport to carry all your midi files for you, hahahahaha.
Steptoe
Yes you are right, what's the point of having stereo "anything' if it goes into a Mono PA desk

So have we resolved the Jack problem ? So the answer realy is to pan to 64 and have a mono lead.
I will burn a couple of CDs for you when I get over there.At the moment most of my stuff is in boxes waiting to get shipped over.

Hi Thingyy
Yes, I just pan all channels to one side (left) and it works great for me,
I don't have any sound quality issues at all.

I think if you're using a stereo PA then running stereo midi files is a must. It runs cleaner and sounds bigger. Each instrument has its own space and we can't underestimate the punter's ear as these days they all listen to quality music via quality equipment. Also running subs for bottom end cleans up your mids & tops but is more expense and more gear to lug.
