Pointing out that not everyone needs all the features of a full-on DAW, Bram Bos has brought us what must be one of the smallest VST-compatible sequencers ever.
Despite its size (the install file weighs in at a meagre 1.8MB), though, Tunafish offers plenty of features, including reverb, delay and flange effects, a built-in sampler, MIDI learn, and the facility to play up to ten instruments or samples at once.
A standard piano roll-style display is used to input notes. Your sequences can go on for as long as you like and are known as Segments. Several Segments can be arranged to form a complete song, which can then be mixed down using the extremely simple mixing console (just ten faders, basically).
Automation can be recorded (though you can´t edit it), and you can even freeze parts if your CPU starts to overload.
While we had a bit of trouble with some stuck notes on certain VSTi´s, Tunafish is still a real bargain.
