I have a keyboard. It can play the basic MIDI sounds. I would like it to have a Hammond organ sound. Since I'm not sure if I can upload new sounds to its MIDI bank, I'm looking for a way to 'effect' my keyboard, so it would sound like a Hammond organ while I'm playing. I do not wish to record what I play, I need this live.
The keyboard has MIDI input/output, so I'm thinking about a setup like this: I connect the MIDI output to my laptop, and the laptop sound output to the amplifier. And as I play, the sound actually comes from the laptop sounding like a Hammond organ. Is there a software to do this, or any other method? (Preferably a free one, but I don't mind paying for it either.)
