installation

binary download

see the releases page.

from source with cargo

requires rust nightly.

cargo install --git https://codeberg.org/unspeaker/tek

from distro repositories

arch linux

tek is available as a package in the AUR. you can install it using an AUR helper (e.g. paru):

paru -S tek

development

you'll need a Rust toolchain and various system libraries.

you can obtain the former using rustup and the latter using nix-shell. there's a shell.nix provided with the project.

from there, use the commands in the Justfile, e.g.:

just arranger

note that tek > 0.2.0-rc.7 will require rust nightly for the unstable features type_alias_impl_trait and impl_trait_in_assoc_type. make some noise for lucky rust rfc2515 if you want to see this buildable with stable/beta.

design goals

inspired by trackers and hardware sequencers, but with the critical feature that 90s samplers lack: able to resample, i.e. record while playing!
pop-up scratchpad for musical ideas. low resource consumption, can stay open in background. but flexible enough to allow expanding on compositions
human- and machine- readable project format simple representation for project data enable scripting and remapping.
