# otel-cli-ideas.sh - some ideas I'm playing with for otel-cli to cover some
# use cases where manual spans or exec don't quite do the trick
#
# another cool outcome is you could run this without the collector in some
# cases without spamming your OTLP endpoint...
#
# I hope to OSS otel-cli under Apache 2 in early April 2021.

# maybe it could background itself and wait for events on a unix socket?

Akai MPK Mini 2 + Fluidsynth + Linux synthesizer

This is a quick & dirty way to attach an Akai MPK mini 2 USB MIDI controller to Linux so the Linux machine can act as its synthesizer. This approach should work for any modern USB MIDI instrument.

Rationale

I looked around on the web and, surprisingly, I didn't find any simple options for quickly starting Fluidsynth up and wiring it to a MIDI controller for simple keyboard usage. There are a few out there that involve using Qsynth which is cool but I didn't want a GUI for something relatively simple.
