Spire offers a drag-and-drop modulation matrix with 8 slots, but the beauty is in the depth. You can modulate almost every parameter—from filter cutoff to oscillator pitch, to FX send levels. The LFOs (4 total) offer step-sequencer capabilities, allowing for rhythmic trance gates.
You have 4 Oscillators available.
Unlike classic VA synths (like Sylenth1) that rely on generated analog waveforms, Spire utilizes a spectral waveform synthesis method. It generates harmonics digitally but processes them in the frequency domain. The result? A clean low-end that never breaks apart, even when using extreme modulation.
In version 1.1.15, the oscillators support:
