Kuensa is a small portable music sequencer which can be connected to USB MIDI and brought out whenever inspiration hits on the go. The computing is done on a Raspberry Pico RP2040 and the audio is handled by a dream SAM2695 module. The device also has serial MIDI I/O to communicate with other devices as desired. 

Internally it contains a lithium ion battery which is recharged via a USB module. Plus it's also got an SD card slot for saving work.

The main idea with Kuensa is to have a convenient tool for portable music making and practicing. Part of the plan was to make the device as distraction free as possible, thus allowing someone to concentrate on the playing rather rather have hundreds of features intruding into the mental image.

This video has a description of Kuensa and a demonstration of current capabilities:

I got caught onto trying to squeeze as much out of a text display and tactile buttons and so far, it's decently usable.

Features which are available so far: 

• Play, Stop and Record on multiple tracks (but record only one track at a time)
• Load, Save songs
• Metronome with tempo adjustment
• Mute tracks
• Configure track instruments (so far this is in a config file)
• Beat counter on the display
• MIDI monitor via LED
• MIDI serial I/O for connecting to other sound devices 

UPDATE 1:

I've been experimenting with a Waveshare Pico that has a TFT screen onboard, i.e:

So far it's working quite well and the entire setup is working as a prototype. It now remains to make a more coherent interface. This opens up the door for other SPI based pico borads e.g. Elecrow 2.4in which has even more features onboard. With more out of the box, it means I have to add less hardware to achive the same result.
