It's natural to try to compose and mix within the same project, working with MIDI data throughout the entire process, but this can pose some unexpected challenges.
While exporting to audio might seem impractical, there are a number of very tangible benefits for when you're ready to put on your 'mixing hat', and most DAWs offer tools that streamline this process.
So, why is bouncing your project to audio such a crucial step when you're ready for a dedicated mix?
Mix Session Preparation
Watch TutorialSwitching from MIDI to audio before mixing gives much-needed performance consistency. MIDI triggers a variety of samples every time a note is played, which means subtle variations can creep in between renderings: timing differences, different velocity layers selected by round robins, or even minor tonal shifts. Bouncing to audio "freezes" the performance, eliminating these variables.
Another major advantage is CPU and RAM management. Streaming samples is resource-intensive, and adding mixing plugins only compounds the problem. Converting MIDI to audio frees up processing power, allowing you to work more efficiently and add complex effects without hitting performance bottlenecks.
Finally, having the visual representation of your performance through waveforms makes it easier to identify and address timing inconsistencies or uneven dynamics. You can clearly see if a note starts too late, ends abruptly, or has an unexpected swell.
When composing, your focus is on what notes are played. In mixing, that concern shifts to how those notes sound.
Think of it like being both the engineer designing a racing car and the driver piloting it. You need different skillsets for each role. Separating these processes helps you approach your work with the right perspective. Once you've finalised the core arrangement, bouncing to audio signals that you're moving into "technical" mode: focusing on balance, frequency issues, and overall sonic clarity rather than note choices.
Our goal is to create clean, organised stems that maximise flexibility and control in the final production stages. Let's look at some essential steps to take before moving to the mixing stage when your composition was created with sample libraries.
Preparing MIDI for Mixing
Watch TutorialReady to commit your composition to audio and formally move onto the mixing stage? Follow the steps below to make sure you have a clean slate to work with when starting your mix.
The first step is simple: remove all plugins from your MIDI tracks, EQ, compression, reverb sends, everything! This isolates the raw sound of the composition, preventing unintended effects on your mix from adjustments made during composition.
Are there exceptions? Yes! If an effect is integral to a sound's character, like a synth pad that you've added a trance gate to that defines its function as a pulse instead of a pad, leave it in place. Removing it would drastically alter the sound.
Now centre all your tracks in your DAW mixer. This might seem counterintuitive if you've already established a stereo image, but it allows for precise positioning during mixing and a clearer understanding of how instruments interact.
Keep the rough balance created during the composing stage, don't reset everything! This initial balance is a valuable starting point. Composers often develop an intuitive sense of arrangement; preserving this is recommended.
Clear file naming and organisation are vital for efficient mixing. Make sure that all your instrument tracks are labelled correctly and intuitively so it's easier to navigate when you do the export.
Before exporting, set your locators correctly. Add a bar of silence before the start and after the end of your piece to provide headroom for any tails, preventing the audio from starting too late or cutting off too abruptly.
Select the correct sample rate and bit depth for your project and save the stems into a dedicated folder labelled something like "Stems". Many DAWs give you options to include channel numbers in your export names (e.g. "31 Bass Drum"). This helps you import them in the same order they were exported, and avoids generic labels. A little organisation upfront saves significant time and frustration later on.
Warning: Do not normalise your audio on export.
