Using a computer to process the audio output from a digital piano.

[indespair]

The rock/jazz organ sound of my digital piano isn't very rich. I would like to use a software to get a good organ sound out of my piano and preferably using an audio output from the piano instead of a MIDI output. Any suggestions?

what your saying is you want to process the output of your keyboard, if so you can use audacity

https://audacity.sourceforge.net/download/

just use the eq and select the appropriate output

I often use my digital keyboard to record on my laptop using MIDI and a program called Mixcraft.
 It's excellent for actually recording, but if I am playing and listening to the modified sound out of my computer speakers there is a lag between the key being pressed and the sound.
 I don't know if there is a way to avoid this?

I don't know if this might be helpful to you, but here's a recording I made by recording a .wav file from my Yamaha Clavinova and then process it a bit in Audacity.

This is NOT my idea of shameless self-promoting, remember, as I'm fully aware that the musical quality is not that excellent, and there are also quite a few mistakes in this take. I did it for sharing with some friends who had asked me for a sample, but most of all I wanted to experiment a bit with Audacity and see what it could do. Actually I was rather pleased with the technical outcome, at least for being a first attempt.
 Except from adding an equalizer profile I used a preset reverb effect to create the soundscape of a fairly big hall, and also a phaser effect on the lowest bass octaves to make the piano sound "bigger".
I also want to try this with the church organ voice, could be interesting.

OK, now I read a bit better. Perhaps you wanted an output in real-time. Sorry for my interruption here, but I let the post remain, in case you should find it useful anyway.

Sounds good ! Pretty much eliminated the digital overtone.

What if I want to add overtones and effects to the original organ sound?

[rangerx]

in this case i would invest in the Native Instruments B4, the extra tones you want wont happen the hammond draw bars are mostly octaves thats how you get the fat sound i own a M3

just did a search the product is called "vintage organs"

If you want to tweak your current sound you could start with Audacity as others have mentioned. 

You may also be interested in virtual instruments.  In such case you play on your digital keyboard, however the sound comes from software on your computer.  The sounds could be samples of real instruments or synthetically created: there are many choices available here.  Your keyboard would need MIDI.  Having a MIDI interface with good reliable low-latency drivers is key on the computer end.
