Need help with Quantum Leap Goliath

I totally agree with Cellius...notation programs are simply not designed to provide high quality audio files for listening purposes. If this is a one time deal, then yeah, import the midi into a sequencing program and commence clean up to get it to sound natural and pleasing. But if you're looking towards the future then seriously consider using Sibelius only for sheet music and a MIDI sequencer for producing your audio recordings.

Jam it back in, in the dark.

I actually use Finale all the time and, truth be told, it's playback has improved remarkably over the last several years. But it still pales in comparison to what you can accomplish sonically with a sequencer. Notation programs were never meant to produce high quality recordings. I shudder at the the thought of trying to use Finale to get a string quartet to play detached in the Baroque style, a harp to strum up and down naturally, or to get a piano to play rubato. It's possible, but it would take an absurd amount of time and it's doubtful that you can make it sound as good as a few minutes of work on a sequencer.

I find that Finale's playback does it's job admirably, but I wouldn't ever put it on my iPod.

How ya doing, buddy?
