playing music via pc part 2

i found out that playing live via a pc is not so suitable. i am not too sure why but sometimes the sound got "stuck" & i had to reset several times during play. it could be the hardware or cabling issue though. it sure can cost embarassment if you are playing in front of audience. so conclusion is that pc is only suitable for recording purpose or simply playing at home where nobody care if you make mistakes.

the solution for me? i am thinking of purchasing a new keyboard with synthesizer capability. so far the only suitable (ie cheap) model is korg X50. i am looking forward to try it & buy it when my disposable income is good enough :)
