Regular readers may recall that I picked up a little battery powered five watt pocket amp with a bluetooth speaker and a quarter inch input jack. Specifically, it is the Positive Grid Spark Go (not an endorsement, just a side note) meant to be plugged into an electric guitar but simultaneously useful for both an aspiring electric violinist and his semi-regular synth jam sessions in the park.

Then too, I threaded the output from my MIDI controller keyboard from the weakling computer speakers directly into the amp, so that when I sat down at my desktop in my home office to practice  I could make use of the richer sounds from the new speaker.

It’s not great for more natural piano sounds, but as I explore the extensive instrument library that came bundled with the MIDI controller I have been building a collection of favourites that are a few standard deviations from natural—hybrids and bells and strings intermingled with raindrops—and many of those have rich bass ranges.

The Spark Go has an interesting feature for a little speaker. If you lay it down on its back it has a bass pad that acoustically enjoins the surface of whatever it touches—the table or desk, in my case—and adds an audible and physical dimension to said surface.

All that is to say, that when I’ve been playing bass heavy instruments on my MIDI controller and the speaker is on the desk the whole thing rumbles with a tactile joy that brings the music to life from and then right back through my fingertips.

Curious technologies lead to simple joys.
