A classic.
Kalimba
Synth: Primer
Oscillators: Set both Osc 1 and 2 to Sine.
Mod Envelope: FM is going to give us that kalimba-style tone, so set destination to FM, and set a quick Decay, around 550 ms. Then set Amount to about Noon. Then turn up Oscillator 2’s Semi knob until you get the bell-like tone you’re looking for. I liked it around 28.
Amp Envelope: Sustain to zero, and a quick Decay and Release, around 400 ms.
Reverb: decent amount of size (around Noon), and a light wetness (around 9:00)
Brass
