FIRSTCALLkeys Turns the Browser Into a Keyboard Rig

Field notes

The interface organizes its sounds into a large set of instrument families, with visible counts ranging from eight Reeds patches to 46 Sound Effects. It combines a curated patch layer— including First Call Concert Grand, Warm Grand, Felt Intimate, and Midnight Rhodes—with a more traditional catalog containing MIDI-style entries such as 808/909 Kit, Tonewheel Organ, and Chorused Tine EP. MIDI connection, mapping, audio testing, auditioning, and favorites are exposed as controls.
