Just an iPad: GarageBand between Glass and Groove

The experiment has a sensible boundary: it’s about an electronic dance track, not every conceivable recording project. Defmod Network explicitly distinguishes between electronic music and acoustic instruments or vocals; he mentions an interface as a possible extension for external sound sources. Here, though, it’s just the tablet. He explicitly lists what’s not being used this time:

His arrangement grows from variations: first, he places a four-to-the-floor kick on the grid. Then he duplicates section A and adds an open hi-hat; the next section gets further drum layers. Not every passage has to be reinvented, it just needs to be musically distinct from the previous one. In the original, this structure is especially clear because the additions are built on the running foundation.

For the synth bass, his declared favorite, the arpeggiator takes over part of the playing: an eighth-note pattern over two octaves, harmonically set to A minor and F. The missing keyboard thus changes the method. The creator initially perceives small delays when playing on glass as a human touch; afterward, he quantizes to straight eighths. This isn’t entirely consistent—and that’s what makes it interesting. He wants to tidy up the downbeats without ironing out every rhythmic quirk.

With the pad preset Celestial Voices and another soundscape layer, the sketch gains extra depth in the arrangement. The available sound parameters are largely left untouched. Here, the preset serves as building material, not as an invitation for hours of tweaking.

That the touchscreen can be more than a keyboard without tactile feedback was already demonstrated by sonicstate in the episode “Sonic Touch #9,” published March 9, 2012. With the Smart Strings shown there, chord pads aren’t just tapped: by rubbing, a crescendo is created, with volume increasing with the speed of movement. This is a different musical task than Defmod’s bass arpeggio, but an elegant idea: the surface maps a gesture instead of merely mimicking familiar keys. The commentary describes the connection directly:

In his ROLI Songmaker video from November 13, 2018, Sanjay C takes the route via additional playing surfaces—explicitly with GarageBand on Mac, not iPad. He too first layers drums and then adds simple chords. With the Loop Block, he controls looping and recording without having to constantly return to the computer.

The more revealing moment comes with the chord sound from Equator Player: Sanjay slides his fingers forward on the Seaboard, changing the sound. Here, the hardware is given a concrete musical purpose, rather than just increasing the device count. While Defmod simplifies playing with the arpeggiator, Sanjay uses the extra surface for sound shaping during performance.
