What it does
Two oscillators, rendered at 2x
Each voice has two free-running band-limited oscillators with cross modulation and two-way sync. They run at twice the sample rate and pass through a 79-tap half-band decimator.
4-pole filter with two slopes
The zero-delay-feedback filter switches between -12 and -24 dB and self-oscillates at full resonance. A 6 dB/oct high-pass filter is there as well.
Voices that differ slightly
Choose one of three analog variation modes, or set six trimpots per voice by hand for pitch, pulse width, envelope, cutoff, resonance and modulation.
Notes sequencer, mod sequencer, arpeggiator
The 32-step notes sequencer has 15 scales, accent and glide, and a second 32-step sequencer drives three modulation destinations. The arpeggiator has 7 modes over 1 to 4 octaves.
Modulation mixer with 11 sources
Two extra LFOs with seven waves feed a mixer with 11 sources and six operations. Velocity, aftertouch, mod wheel and key tracking each get a Bezier response curve.
Three effect slots and four macros
Pick from 11 effects, including reverb, delay, chorus, compressor and a 5-band EQ, and run the slots in series or parallel. Any control can join one of four renamable macros.
Good to know
- Polyphony stops at 16 voices, and unison stacks 2 to 8 of them.
- Sound comes from the two modelled oscillators per voice. Amberlight does not play samples.
System requirements
- macOS 11 or later
- Apple silicon or Intel Mac
- Formats: AU, VST3, Standalone
- A host that loads Audio Units or VST3 plug-ins, for the plug-in versions
