Amplitude that follows your session tempo, two more ways to move a signal, and a screen that shows you what it is doing to the audio - not a picture of what it might be doing.
Four clips, rendered straight through Tremmy’s own engine. The source is a Rhodes-ish chord and a plucked figure, synthesised so they are ours to give away.
Most tremolos draw you an idealised wave. Tremmy draws the modulation it is actually applying - smoothing, swing and shape included - over the audio that actually went through.
The signal arriving is drawn dim underneath. The signal leaving is drawn lit on top. The curve over both is the modulation, run through the same slew the engine uses, so at high SMOOTH the corners round off on screen exactly as they do in your ears.
Amplitude, with a stereo phase offset. The tremolo everyone means when they say tremolo, locked to your session tempo.
Splits the signal and modulates the two bands against each other. The level holds still and the tone sways instead.
Constant-power positioning, where WIDTH decides whether the channels sweep together or in opposition.
RATE snaps through note divisions when you are locked to the host and sweeps in hertz when you are not. SHAPE morphs sine through triangle to square. DEPTH and MIX do what they say.
Underneath, five cast-stone trims: SMOOTH rounds the modulation so a square never clicks, GROOVE swings every second cycle, FEEL moves the trough so the dip can snap and recover slowly, or swell and drop sharply.
Switch on GLIDE and every dip becomes a run-up: the pitch starts a whole tone below and sweeps into place as the level climbs back. The time knob is a share of the cycle, so it stays in proportion whatever the tempo or the rate.
It works by sweeping a delay line - the same thing tape does when it changes speed - and it resets during the dip, where the signal is quietest. The tremolo pays for the trick.
Eleven factory presets, a step sequencer, a drawn curve editor, MIDI learn on every control, A/B compare, and a strip mode when you want it out of the way.
No account, no licence key, no trial that expires. Just Tremmy with joy!
If it earns a place in your sessions, you can DONATE to support what comes next. Entirely optional, and every bit of it goes back into the work.

Tremmy is an audio effect. On a MIDI track that means dropping it after the instrument, so it works on the sound the instrument makes.
