Another #GuitarPedal completed.

A few years ago I designed a pedal with a complex effect (but just a single knob and an expression pedal as controls) for a guy but in the end that wasn’t what he was looking for and he didn’t pick it up. So I had this pedal stuck with me. 😑

Recently a friend asked me for a long delay effect with a 15 second memory and the footswitch only muting the delay input (FX always on duty). It was an opportunity to #recycle the old pedal, based on a #DaisySeed board. So I drilled new holes in the enclosure to host 3 knobs.

But wait, there’s more. ➡️

Descubrí un patch caótico con una porción de El nido de la perra (así bauticé a mi sistema heterogéneo de síntesis). Es capaz de hacer cosas muy pequeñas y muy agudas.

Disfrútenlo y si quieren denle like y sub. :-)

Tonight’s project: Soldered and put together a Daisy Seed based chip guitar pedal. Already got it flashed with examples from https://github.com/bkshepherd/DaisySeedProjects/blob/main/Software/GuitarPedal/README.md

Getting ideas about what I want to try to modify or cobble together. This patch (shown as “Cloud Seed” on the display) is a nice shimmer reverb, and there’s also chorus, tremolo, delay, a looper, a metronome, and more in the examples.

I’m not a C++ programmer but I’ve done enough Arduino programming and professional Rust programming that I can figure this out. The DSP stuff will be what I have to learn.

My little daisyseed synth project is currently stalling on the whole "C++ is just the WORST language" problem.

There's a class in the DaisySP library which is *almost* what I want. So I should be able to just subclass it and work from there, right?

Well, no, because none of the functions that I want to override are declared "virtual", so I'd have to edit and re-build the library.

I'm sure this is all in the service of runtime efficiency, at some level. But, you know - it's a 480MHz ARM processor. I think a little indirection wouldn't be a huge deal.

I will just write the whole thing from scratch, all 100 lines or so of it. But it's *IRRITATING*, you know?

Finally gotten around to having a look at my Daisy Seed.

My "notes to self" to get to a musical "hello world" are now up here: https://diyelectromusic.com/2024/12/18/getting-started-with-daisy-seed/
