Thanks for this further suggestion! So you refer to `sound_card_buffer_size` here?

When I go below 512, I get no sound at all. With 512, the delay seems unchanged, but I get artifacts in the sound. With 1024 and above, sound is ok, but the delay if still there. Not being able to go lower is probably a limitation of my sound card…

Also, I am wondering why the `tb303` does not show any visible delay, as it should also be affected by the buffer boundary “error”.

In the project where the issue first appeared for me, I could circumvent its audible effect by shortenting the first note played by the respective synth (published to in\_thread [here](https://in-thread.sonic-pi.net/t/first-sonic-pi-track-made-with-literate-programming/5308/7)). But still, I would be interested in ways to preventing the issue from ground.
