9. Frequently Asked Questions

What is spline synthesis and how does it work?
Spline synthesis is a form of waveform synthesis where the oscillator waveform shape is defined by mathematical spline curves — smooth curves that pass through a set of user-defined control points. Unlike fixed waveforms in subtractive synthesis or pre-drawn wavetables in wavetable synthesis, spline synthesis allows users to draw any waveform shape imaginable by placing and moving control points that define the smooth curve of the waveform. This gives Spline Synth complete oscillator freedom — every possible waveform shape between a pure sine wave and a complex custom waveform is achievable by simply drawing the desired curve shape.

Does Spline Synth work with FL Studio?
Yes, The Wave Warden Spline Synth 1.1.1 is fully compatible with FL Studio on Windows as a VST2 or VST3 plugin. Load it as an instrument in FL Studio’s channel rack for full MIDI control and automation support — including automation of the waveform morph position, filter cutoff, modulation parameters, and all other Spline Synth controls.

How is Spline Synth different from wavetable synthesizers?
Wavetable synthesizers use tables of pre-drawn waveform samples — you select from a library of existing waveforms and morph between them. Spline Synth instead allows you to draw completely custom waveforms from scratch using spline curves, meaning every waveform is unique and entirely created by you. The morphing in Spline Synth also differs — it smoothly interpolates between your custom drawn waveform states using spline mathematics rather than blending between sampled waveform tables, resulting in uniquely organic and smooth timbral transitions.

Is Spline Synth good for beginners?
Spline Synth has a steeper learning curve than preset-focused synthesizers — getting the most from its waveform drawing and morphing capabilities requires some exploration and experimentation. However, the comprehensive factory preset library provides an excellent starting point delivering great sounds immediately, and the visual spline editor makes the synthesis process intuitive and immediately understandable even for users new to waveform-based synthesis concepts.

Can I use custom modulation shapes in Spline Synth?
Yes — one of Spline Synth’s most distinctive features is that the same spline drawing engine used for oscillator waveforms can also be used to draw custom LFO and modulation shapes. This means you can create modulation curves of any shape imaginable — not just standard sine, triangle, or square LFO waves — opening up unique and complex modulation possibilities that standard synthesizer LFOs simply cannot achieve.

Is The Wave Warden Spline Synth available for macOS?
This version — The Wave Warden Spline Synth 1.1.1 — is the Windows version supporting VST2, VST3, and AAX formats on Windows 10 and 11. Check The Wave Warden’s website for the latest information regarding macOS availability for Spline Synth.
