The Subdecay TremCoder 2 is a tremolo sequencer pedal: a tremolo whose speed and shape are driven not just by a simple LFO but by programmable patterns of 4 to 32 steps. Subdecay describes it as "a tremolo/sequencer with MIDI," and it carries eleven warp-able LFO shapes, from the familiar sine and triangle through hard-cornered ramp, saw and variable pulse waves, to pattern-based shapes and two shapes with envelope speed control1.
Controls and presets
The Shape/Preset knob does double duty: it selects the LFO shapes during play, and it picks a save location when you are storing a sound. Saving is done from the footswitch: hold the bypass switch for two seconds, select a place to save with the Shape/Preset knob, then press again. The pedal holds eleven user presets1.
On top of the shapes themselves, the warp knob "further transforms each LFO shape," so a single shape can be pushed into different territory without leaving the knob1.
| Control | What it does |
|---|---|
| Shape/Preset knob | Selects LFO shapes and preset save locations1 |
| Warp knob | Further transforms each LFO shape1 |
| Bypass switch | Held for two seconds to save a preset, pressed again to confirm1 |
Tap tempo and MIDI
Tap tempo is built in, with divisions ranging from 16 beats down to 32nd notes, so patterns can be stretched or subdivided against the song1.
For MIDI users, Subdecay lists three capabilities: all parameters can be accessed via MIDI CC messages in real time, MIDI clock sync keeps rhythms locked to tempo, and presets can be changed via MIDI. That puts the pedal in territory shared with dedicated MIDI pedals while staying a single-effect box1.
Where it came from
The TremCoder 2 is a tremolo/sequencer pedal from Subdecay, described by the maker as "A tremolo/sequencer with MIDI." Subdecay states: "this pedal packs in multiple LFO shapes, repeating patterns and a programmable 32 step tremolo sequencer," with a warp knob that offers "Further transformation of each LFO shape"1.
Subdecay lists the TremCoder 2 as shipping in up to one week from order1.
Subdecay notes that the TremCoder 2 lists for $299.00 USD and weighs 20 oz, and that the pedal may take up to one week to ship1.

Questions
How do you save a preset on the Subdecay TremCoder 2?
Hold the bypass switch for two seconds, then use the Shape/Preset knob to select a save location, and press the switch again to save. The pedal offers eleven user presets, and the same Shape/Preset knob is used to pick LFO shapes during normal operation.
Can the TremCoder 2 sync to MIDI clock?
Yes. Subdecay says the TremCoder 2 supports MIDI clock sync so rhythms stay locked to tempo, all parameters can be accessed via MIDI CC messages in real time, and presets can be changed over MIDI.
How many steps can the TremCoder 2 sequencer use?
The sequencer is programmable from 4 to 32 steps, so patterns can be as short as four steps or run a full 32 steps for longer, evolving tremolo rhythms.
What changed from the original TremCoder to the TremCoder 2?
Subdecay says the TremCoder 2 took cues from the original TremCoder and then expanded and improved on it, adding presets, full MIDI compatibility and a programmable 32-step sequencer to the original design.
Is the Subdecay TremCoder 2 stereo?
Subdecay teased the Tremcoder MkII in August 2023 as a stereo tremolo, adding presets, full MIDI compatibility and a 32-step programmable sequencer to the original design.
