these days i normally use realTracks for just about anything but having revisited some of my midi only tracks from yesteryear listening with the TTS1 and then halion sonic i'm not convinced that to me it makes a huge amount of difference.YMMV as Mario always says but the TTS1 is free and the OP can try it easily enough. And if i remember correctly Peter Gannon says it's the default synth they use when creating BIAB styles.
