Let’s make a micro looper, and learn how to use buffers for recording, playing and manipulating sounds in real time on the Daisy Seed microcontroller.
Case study: Build looper with controllable loop start / length / pitch shift
In this workshop we will build a sampler/looper on the Daisy Seed microcontroller. We will be working in Arduino, using the Daisyduino, but we'll also touch on C/C++ programming topics. You can already check the code out here > Synthux Github - Daisy Sampler / Looper.
Understanding the Daisy Seed buffer
The Daisy Seed has a 64MB SDRAM chip built-in. This chip can be used to record and play our samples in real time. We'll learn how to set up the buffer and understand circular buffer basics.
Tweaking knob behaviour and mapping
How should our knobs behave? We'll learn how to define the range of the knobs, define the curve response, directional or bidirectional and more.
