This is using all the Teensy (and chatgpt) goodness to do one thing well.</div><div><br></div><div>And yet, it seems there’s one thing that could be added, perhaps some granular controls. Most basic would be to move a single start/end of sample around at same or variable loop length.</div><div>It gets “granular” when the controls have coarse/fine modes. With great restraint we can forego an OLED waveform display.</div><div>But then, shucks, you need at least one ADSR envelope, preferably 2 so you can move the grains (any or all points) differently than the amplitude with the envelope. </div><div><br></div><div>Yeah, this is why you should never let me get involved with design… It snowballs. Menu diving gets into everything. </div><div>The simplicity of this project is beautiful.</div><div><br></div><div>Benjamin </div><div><div><br><blockquote type="cite"><div>On Jan 29, 2026, at 7:09 AM, Heitor Alves via Synth-diy <synth-diy@synth-diy.org> wrote:</div><br class="Apple-interchange-newline"><div><div dir="ltr">Hi All<div><br></div><div><a href="https://github.com/HeitorAL9000/TeensyLooper" target="_blank">https://github.com/HeitorAL9000/TeensyLooper</a></div><div><br></div><div>TeensyLooper<br>An audio looper with reverse capabilities and low latency, reverb and based on the Teensy (4 and 4.1) platform.<br><br>This project is born out of the "need" for a simple audio reverse tool for my live setup.
