Alsa Sequencer Remote Control

Creates an http server that allows to easily control alsa sequencer connections.

I use it to connect all my MIDI gear to a Raspberry Pi, and control the connections with my mobile.

Very handily it is packaged as a PWA, so it can be installed as an app from the browser.

After installation it is available at http://IP and can be installed as a PWA (Google Chrome or Firefox, click add to home screen).

Use

The patch screen shows the outputs, and you can add to which input it is connected from the selector. Connections can be removed pressing the x.

There is a Monitor button for each output that allows midi monitoring for wasy troubleshooting.

All connections are remembered and if a device dissapears (unplugged for example), when it reappears its reconnected. Same happens after reboots.

My normal use case is always running in a raspberry pi, and all my MIDI gadgets connected.

Compile

make build

or

make run

To develop you can do make run in one terminal an make serve in another, so any change on the frontend is automatic. The url would be http://localhost:8001.

ARM

I dont know enough go to make this work, but when compiing for ARM I need to change some lienes at alsaseq.go. Look for ARM to know which ones.
