How do you make samples sound better in Ableton?
Get a great sounding mix going without many plugins. Export all tracks un-dithered, at 24 bit, the same sample rate you recorded at. Import the tracks into Pro Tools, Logic, or another DAW you are comfortable with. Hear your tracks come to life and take it a step past what was possible in Ableton!
Is there a tuner on Ableton?
UPDATE: Version 9.2 of Ableton Live introduced the Tuner, a native Live audio effect which is extremely accurate. Great for tuning guitars, samples etc.
