SYLPHAUDIO

Bass that listens.

The first neural bass instrument. Describe it, reference it, or let it write the bassline for your track.

Dubstep“aggressive dubstep growl with metallic formants”
Melodic techno“deep round sub with a slow wobble, almost clean”
Drum & bass“wide detuned reese, dark, moving”

Press create. Then play it.

This is the instrument running in the page — same idea, fewer knobs. Pick what goes in, generate, and play it with your mouse or your keyboard.

References — combine them

How it works

Three ways in.

You can start from nothing but a sentence, from a sound you already like, or from the track you’re working on. They combine.

01 · Describe

Write it, hear it

The assistant turns your words into the model's own dialect, and the model generates the sound from noise. Two octaves of samples, mapped across the keyboard.

Latent diffusion. 25 samples in about 30 seconds.

Your idea

02 · Reference

Clone a timbre you like

Drop in a clip and it takes the colour, not the notes. You set how much to copy of each thing: timbre, movement, attack — per reference, so two clips can each give you a different half.

Cross-attention on the identity, not a sample swap.

Identity transfer
03 · Compose

Let it write the line

Feed it the passage of your track. It reads the key, the chords and where the kick lands, and writes a bassline that fits in the holes the drums leave.

MIDI out, dragged straight into your DAW.

Bassline over your drums
The instrument

It all happens in one window.

No hopping between screens: the prompt, the references, the instrument map and the waveform are all in view at once. Tap the dots to see what each area does.

The NSE Bass interface: the prompt field, the references bar, the waveform view with its envelope, the instrument map and the preset library.
Demos

Every one of these started as a sentence.

The prompt is printed above each sound, and you can hear it on its own or sitting in a mix — a bass that sounds good alone and disappears in a track isn’t a good bass.

Before / after

The same track, without and with.

No bass at all, then the line Sylph wrote and played for it. Nothing else in the mix changed.

After“bassline written by Sylph, in key, on the chords”
Where it fits

Not a replacement. A different starting point.

Including the row where a normal synth wins, because you’d find out in the first five minutes anyway.

An “instrument” is one generation: two octaves of samples mapped across the keyboard. Auditioning takes before you commit doesn’t count against it.
