I want to be able to play my keyboard along with some songs I have in mp3.
I first tried playing them with an external player like winamp, while I played the keyboard with Reason, and have the windows mixer mix the sounds, but that forces me to use DirectSound, which causes too much lag in reason. I can use ASIO in Reason, but that locks out any other applications from using my soundcard.
The best solution seems to have Reason play these files, mix the music with the keyboard sounds, and use ASIO for it all so there is no lag.
Does anyone know of an easy way to get a ~3minute song to play within reason so it can be mixed with another instrument, and be done all lag-free? I tried converting the mp3 to a wav, then using the sampler to get it to play, but that causes the file to play at all weird speeds.
