What it does
A drive that moves with your playing
DriveBridge is an audio effect: put it after a synth or on any track. Its clipping moves with how you play, the output stays as loud as the input, and you judge it by its tone, not by more volume.
It is the Drive from the Helin synthesizer, on its own, with an oscillator added to move it.
Set it up in AUM
Four steps to a driven sound
1
Add DriveBridge
In AUM, add DriveBridge as an effect after a synth or on any audio channel.
2
Pick a mode
Step through Valve, Tape, Pedal, Fuzz and Fold with the arrows.
3
Set the drive
Raise Drive, then drag on the picture: up and down for Tone, sideways for Character.
4
Make it move
Give the oscillator a depth on any control, free or in time with the host.
Opening the DriveBridge app itself shows the same steps.
Features
Five drives, one oscillator
Valve
A two-stage preamp whose clipping moves with your playing and sags on hard hits.
Tape
Saturates, rounds and wobbles.
Pedal
An overdrive that leaves the low end clean.
Fuzz
Starves and sputters, and its last quarter wrecks the sound.
Fold
A wavefolder for hollow, vocal and metallic tones.
Level matched
As loud as the input up to 70 % Drive; past it the top opens up by up to 6 dB.
Oscillator
Moves Drive, Character, Tone, Body, Dynamics and Mix, each by its own depth. Six shapes, free or synced.
Cab
Puts a speaker cabinet’s band after the drive.
A picture per mode
Glowing valves, a stompbox, a fuzz box and its battery, a tape machine, a knot of light.
Automation and presets
Every control is an Audio Unit parameter. 14 built-in presets in the host’s preset menu.

Common questions
Why doesn’t it get louder when I raise Drive?
On purpose: the output stays as loud as the input up to 70 % Drive, so you hear the tone change and not the volume. Past 70 % the top opens up by up to 6 dB.
Is it the same drive as in Helin?
Yes, the same engine. DriveBridge adds the oscillator and a picture for each mode.
Can AUM automate it?
Yes. Every control, the oscillator depths too, is an Audio Unit parameter, saved with the project and in the host’s presets.

This policy covers the DriveBridge app and its Audio Unit plugin. DriveBridge is made and published by Tanel Teemusk. In short: the app collects no data.
What the app collects
Nothing. DriveBridge has no accounts, no analytics, no advertising and no tracking, and it makes no network connections. Nothing about you or the way you use it is sent to me or to anyone else.
Your settings
Your settings are saved in your host’s session and presets on your device. They leave it only if you share them yourself.
Children
Since the app collects no personal data from anyone, it collects none from children either.
Changes to this policy
If this policy changes, the new version will be posted on this page with a new date at the top.
