Sound familiar?
The problem.
The same three chords
You hear rich chords in your head, but your hands keep finding the same basic triads.
Theory is a wall
Ninths, elevenths, voicings, voice leading... you just want to make music.
Presets sound like presets
Chord packs are stiff MIDI. Nothing about them feels played or yours.
City Seoul turns your keyboard into a chord instrument: every key is a full, voiced chord that fits your key, with strum and feel that make it sound played.

What it fixes
Problem in. Solved.
ONE KEY, ONE CHORD
White keys play the 7 chords of your key, black keys the colour chords. C is always home, so your fingers never move.
16 VIBES
Shibuya 1984, Midnight Lydian, Han River Sunset, Bossa Seoul, Trap Soul and more, each with 12 progressions.
4 VOICINGS + AUTO
Close, Spread, Soul and Airy, with smooth voice leading. AUTO picks a fresh one for every chord.
FEEL
Strum, velocity, tone, space and glide make it sound like a player.
YOUR SOUND
Built-in keys, vocal, flute and vintage synths, or drop in any sample and play chords with it.
DRAG MIDI
Everything you play is kept (up to 256 chord changes). Drag it into your DAW or into another synth.
Vibes
How it works
Three steps. That's it.
Made for producers and artists who hear lush chords in their head but don't know music theory.
Pick a vibe
Choose a preset, a key and major or minor.
Play
Every key is a full chord. Try progression mode for ready-made changes.
Drag the MIDI
Pull the chords into your beat, or into Glitchy Seoul.
Who made this
Built by an artist and producer.
I'm Sungwoo. I've been making music for over a decade. I produced for pH-1 on his debut with a major Korean label, performed at KCON three times and been featured on Korean national TV.
I grew up on neo-soul and Japanese city pop, and I wanted anyone to be able to play those chords without years of theory. So I made every key a chord that just works.
Lush neo-soul and city-pop chords from one key. No music theory, no wrong notes.
One plugin. One price.

Questions
Asked & answered.
Will it work in my DAW?
Yes. City Seoul ships as VST3 and AU, so it runs in Logic, Ableton, FL Studio, Studio One, Reaper, GarageBand and any DAW that loads those formats. Pro Tools (AAX) isn't supported yet.
Mac or Windows?
Both. Mac (Apple Silicon and Intel, AU + VST3) and Windows 10/11 64-bit (VST3). One purchase covers both.
Do I need to know music theory or mixing?
No. That's the whole point. Everything is built so you can get a great result fast, then tweak if you want to.
How do I install and unlock it?
Right after checkout you get an email with the download and your license key. Run the installer, put City Seoul on a software instrument (MIDI) track, click Unlock and paste your key. After that it works offline.
How many computers can I use it on?
Your key unlocks up to 3 computers.
Is it a subscription?
Never. One payment, yours to keep, with free updates.
What if it's not for me?
30-day money-back guarantee, no questions asked. Put it on a real beat, and if it doesn't earn its spot, email sungwoo@heysungwoo.com for a full refund.
Windows says "Windows protected your PC". Is it safe?
