RK-Ambience
Use the complete room reverb: length, room shape, tone, damping and gate, with 89 programs.
The RK-Ambience is a room reverb with every control at hand: length, room shape, tone, how much low and high end fades over time, and a gate that closes the tail. It comes with 89 programs besides the Default, and every new instance starts on Default.

In EQ and DAMPING, each control is dual: the outer ring is the frequency, the inner knob is the gain or amount, each with its own value box.
The controls
| Section | Control | What it does |
|---|---|---|
| GATING | AMOUNT | How much the gate closes the tail; at 0 it does nothing |
| GATING | ATTACK and RELEASE | How fast the gate opens and closes, from 10 to 1500 ms |
| DECAY | TIME | How long the reverb lasts, from 100 ms to 20 s |
| DECAY | DIFFUSION | From separate echoes to a smooth wash |
| DECAY | HOLD | Lit, the tail stays, endless |
| SHAPE | SIZE | The size of the room |
| SHAPE | PREDELAY | The time before the reverb starts, up to 500 ms |
| SHAPE | WIDTH | From mono to wide |
| SHAPE | QUALITY | Denser and smoother, using more processing |
| SHAPE | VARIATION | Each press, another arrangement of the same room |
| EQ | BASS and TREBLE | Ring: where the shelf starts; GAIN: less or more lows or highs in the reverb, from −18 to +6 dB |
| DAMPING | BASS | Ring: below it the lows decay at their own time; AMT: that time against TIME, from 10 to 400 % |
| DAMPING | TREBLE | Ring: above it the highs decay at their own time; AMT: that time against TIME |
| MIX | DRY/WET | The slot's Dry/Wet |
