Use a specialized arpeggiator or generative music app to play a virtual instrument inside your primary DAW.
is a technique used in music production to route MIDI data from one software application to another on the same computer, or back into the same application for advanced automation. Essentially, it creates a "virtual MIDI cable" that allows programs like Ableton Live, Logic Pro, and standalone synthesizers to communicate as if they were physically connected by hardware cables.

Kaelen was a ghost in the machine. A “patch rat,” they called him—someone who built the invisible bridges between instruments, not to play music, but to make the playing possible. He lived in the crawl spaces of the Metropolis Symphony’s server farm, his own neural jack permanently glitched, forcing him to hear the raw, unfiltered data-stream of the city’s sonic infrastructure.

In computing, a loopback address sends your signal back to yourself. In MIDI, it meant a virtual cable that connected a device’s output to its own input. Pointless. Suicidal. A dog chasing its tail until it collapses.
At first, nothing. Then, a single piano key: . It played, but because it was a loopback, that C4 signal traveled out, turned around, and slammed back into the synth as a new instruction. Play C4 again. And again. But each time it looped, the signal degraded. The note bent. A harmony emerged—a ghost of a fifth above. Then a dissonant seventh. The single key began to metamorphose .
