Hold a chord, turn one knob, get an arpeggio.
SparkitRaw is a MIDI arpeggiator: it takes the chord you hold and outputs a tempo-synced arpeggio of MIDI notes. Because it's a MIDI effect, you place it before an instrument — as a MIDI effect ahead of your instrument in your DAW.
Fully signed and notarized for macOS as AU, VST3, and Standalone.

SparkitRaw turns a held chord into a running arpeggio, all locked to your host tempo. There's one big ENERGY knob: turn it up and the arp gets faster and bigger — the note rate climbs (1/4 → 1/8 → 1/16 → 1/32), it spans more octaves (up to 4), and the pattern opens up from a simple upward run into an up-and-down motion. Turn it down and the arp settles into a slow, sparse pulse.
Hold a chord and it plays; let go and it stops. Any non-note MIDI (like pitch bend or CC) passes straight through. As you ride the knob, the Fire Head mascot climbs and a spark fires up it on every note, so you can see the pattern play.
Being a MIDI effect, SparkitRaw doesn't make sound on its own — it sends MIDI to whatever instrument sits after it in the chain.
