In this tutorial, I show how to record and loop simple acoustic guitar parts with Caustic's PCM Synth. The process works for any type of instrument/vocals/whatever that you want to include alongside your Caustic synth and drum tracks.
It's not like recording audio in a multi-track DAW. Your don't record into a timeline, you simply record parts "live" as you play along to your Caustic project. You then edit the audio - and loop it if you want to - with PCM Synth and assign each recording to it's own key on the keyboard.
This method works best for recording short phrases and loops - not long recordings for the duration of the song. But since you're using Caustic in the first place, there's a good chance that this fits your production style anyway. There's a lot you can do with it.
In Part 1 of this tutorial, I show how to record into PCM Synth, using 3 simple acoustic guitar parts that I'm playing live. I then show how to edit and loop the 3 parts and assign each to its own key. The final loops play in sync with each other and to the Beatbox track.
In Part 2, I show how to use the 3 loops as separate tracks, and how to use PCM Synth's Filter and LFO to process the loops and create some rhythmic tempo-synced effects
In Part 3, I show how to process the 3 loops even further and create some interesting rhythmic variations using PCMSynth Patterns.
In Part 4, I show how to use Modular Synth's Filter, LFO, Envelope and Arpeggiator to process tracks even further.
