Virtual tuning engine
DOWN//TUNE
A real-time virtual tuning engine built from the ground up specifically for electric guitar. Change tuning instantly while keeping the attack, weight and feel that make a guitar sound like a guitar.

Change tuning. Keep playing.
From the guitar in your hands to the tuning in your head.
DOWN//TUNE is designed to make virtual tuning feel simple: tell it where the guitar starts, choose how far you want to move, and it shows you exactly where you land.
02
Choose the transpose.
Move from -12 to +4 semitones for normal virtual tuning, with dedicated Whammy options when you want to go further upward.

DOWN//TUNE translates the shift into the resulting tuning name, so you can think like a guitarist instead of doing semitone maths.
Why DOWN//TUNE exists
Built for guitar. Not adapted to it.
Most pitch-shifting technology is designed to work with almost anything. We took the opposite approach and developed our own HALF//SUN pitch engine around the behaviour of electric guitar.
Deep dive: why we built our own engine
A distorted guitar is an unusually difficult signal to pitch shift. Palm mutes create huge transients, chords contain overlapping harmonic information, sustained notes expose instability, and high gain makes artifacts much easier to hear.
So rather than starting with a general-purpose library and building a plugin around it, we started with guitar. The engine was repeatedly developed and tested around power chords, full chords, palm-muted riffs, fast picking, sustained notes, clean tones and high-gain playing.
The goal was never simply to make the pitch lower. It was to make the result useful to a guitarist.
That meant listening for the problems that matter under the fingers: transient smearing, unstable chords, low-end movement, warble on sustained notes and the way high gain exposes artifacts that can stay hidden on cleaner material.
We then built the surrounding workflow around the same guitar-first idea — multiple pitch modes for different jobs, pre-pitch gating, virtual tuning readout and post-shift enhancement controls.

Three pitch modes
One engine configuration can’t do every job.
Latency and maximum analysis quality pull in different directions, so DOWN//TUNE gives you three purpose-built ways to work.
LIVE
Our lowest-latency mode for writing, practising and playing situations where the connection between your hands and the sound needs to feel as immediate as possible.
Lowest latency
Where it fitsBest for: writing, practising and latency-sensitive real-time playing.
Explore all three modes
LIVE prioritises immediacy for real-time playing.
TRACKING is the everyday balance between responsiveness and pitch-shifting quality, tuned around guitar chords, riffs, transients and sustained notes.
MIXING gives the engine substantially more analysis time for recording, reamping, editing and bouncing when latency is no longer the priority.
Developed around real guitar problems
Heavy guitar exposes everything.
Pitch shifting a clean, simple signal is one thing. Pitch shifting a high-gain guitar chord while keeping the pick attack, palm-mute impact and harmonic structure believable is another.
Palm-muted riffsPower chordsFull chordsFast pickingSustained notesHigh gainExtreme low tunings
What we focused on during development
Palm mutes create large, fast transients. Chords create overlapping harmonic information. Sustained notes make modulation and instability obvious. High gain then magnifies small pitch-processing artifacts.
So DOWN//TUNE was repeatedly evaluated using the material that tends to break a pitch shifter first: dense chords, low-string chugs, fast changes in articulation and long sustaining notes.
That process is also why the plugin includes its own enhancement section instead of treating pitch shifting as the end of the job.

Enhancement engine
Put back what extreme down-tuning takes away.
Pitch shifting changes more than pitch. DOWN//TUNE includes a dedicated set of guitar-focused processors designed to preserve attack, focus, body and control as you move lower.
PICK ATTACK
Restores transient definition that can soften as the guitar is shifted lower, helping fast riffs and articulate picking stay clear.
Real enhancement controls
Actual enhancement controlsReal crop of PICK ATTACK / PUNCH / TIGHT / WEIGHT / GATE.
Why the enhancement engine exists
Moving a guitar downward changes more than its fundamental pitch. The front edge of the note can soften, palm mutes can spread into the low mids, and removing that movement too aggressively can leave the result feeling thin.
PICK ATTACK restores transient definition. PUNCH brings back forward presence. TIGHT controls low-mid movement around palm mutes. WEIGHT returns useful low-end body after the excess has been controlled. GATE works before the pitch engine so the shifter receives a cleaner, tighter signal.
The idea is not to turn DOWN//TUNE into an amp sim. These controls are there to help the shifted guitar arrive at the amp stage in a more useful state.
The rest of the system
Everything needed to move between tunings without breaking the workflow.
Virtual tuning
Know exactly where you landed.
Choose your physical tuning, change the transpose amount and DOWN//TUNE calculates the resulting virtual tuning for you.
Learn more
If your guitar is in Drop D and you move down two semitones, the plugin shows Drop C. Continue lower and the naming follows into extended and double-drop ranges, so you never need to stop and calculate note names.
Extended-range tuner
Built for where you’re going.
The built-in tuner extends well below conventional guitar ranges for standard instruments, baritones and guitars already tuned extremely low.
Learn more
The tuner listens to the physical guitar signal before transposition. Its segmented display gives you an immediate view of whether the note is flat, sharp or centred before the signal enters the pitch engine.
Whammy
Go beyond normal transposition.
Dedicated +12 and +24 semitone Whammy effects give you octave-up pitch jumps without loading another pitch plugin.
Learn more
Use it for octave-up leads, transitions, special effects and exaggerated pitch movement while keeping the effect inside the same DOWN//TUNE workflow.
ASSIST
Move quickly without losing the musical context.
DOWN//TUNE keeps the tuning workflow readable while you move through semitones, so experimentation stays fast instead of becoming a calculation exercise.
Learn more
The transpose controls are designed around quick changes while the physical and virtual tuning displays keep the relationship between the real instrument and the shifted result visible.
Input + output
Keep levels under control.
Dedicated input and output controls make it easy to level-match DOWN//TUNE with the rest of your guitar chain.
Learn more
Use the input stage to present a sensible level to the pitch engine and the output stage to match the processed level into the next plugin in your chain.
Workflow
Change tuning. Keep playing.
Put DOWN//TUNE before your amp sim, choose the tuning and build the rest of the rig exactly as you normally would.
Learn more
One guitar can cover a much wider range of writing and recording situations without stopping to restring, change setups or reach for another instrument every time you want to test a different tuning.
Built to disappear into your rig
One guitar. A lot more range.
DOWN//TUNE is designed to sit right at the front of the software guitar chain. Choose the tuning, then treat everything after it exactly as you normally would.

Where should DOWN//TUNE go in my signal chain?
For the normal guitar workflow, place it before your amp sim. That lets DOWN//TUNE work from the clean instrument signal before distortion and the rest of the rig are added.
Which mode should I start with?
TRACKING is the best general starting point. Use LIVE when the lowest possible playing latency matters most, and move to MIXING when you can trade latency for more analysis during reamping, editing or bouncing.
Does DOWN//TUNE only tune downward?
No. Normal transposition runs from -12 to +4 semitones, and the dedicated Whammy section adds +12 and +24 semitone effects.
Does it replace physically setting up a guitar for every tuning?
That isn't the goal. DOWN//TUNE is designed to remove the friction of changing tuning while writing, recording, practising and experimenting. It gives one well-set-up guitar access to a much wider range without stopping the session.
When does the free trial start?
The 72-hour trial begins when you activate it inside DOWN//TUNE, giving you three days to test the plugin with your own guitar, interface, amp sims and sessions.
Do I need a subscription?
No. DOWN//TUNE is sold as a full licence, with a separate 72-hour trial available if you want to test it first.
