300 Chords. All Analog. All Killer.
150 major. 150 minor. Pads, keys, synths, 7ths, 9ths — sampled from six legendary machines: Roland D50, Yamaha DX7II, OBx6, Roland Jupiter X, Micro Korg, and Roland System 8. Every chord captured through a Neve 1073 preamp, Apollo 8 Gen II, Trident console, and API 2500. No emulations. No shortcuts. Just real hardware, real warmth, real character.
Simple Controls. Serious Sound Design.
Shape every chord exactly how you need it. Attack and release let you go from snappy stabs to long, evolving pads. Filter and resonance carve out space in your mix. Reverb adds depth, delay adds movement. Glide lets you slide between chords instead of jumping. Transpose shifts everything to any key in one click. No menus. No pages. Everything right in front of you.
