FAST GRIP
Catch the peak before it jumps out.
The FET-style gain stage reacts quickly to sharp transients, then lets the sound return with musical movement. It is built for the moment when a track needs control without losing its push.
CP-FET51A for Windows VST3.
Hit fast.
Keep the weight.
A fast FET compressor for vocals, bass, and drums.
It catches sharp peaks before they jump out,
then brings the dry core back with Mix.
Use Age to choose the texture,
and keep the track alive while it moves forward.

Featured — Fast Peak Control
CP-FET51A
For vocals, bass, and drums that jump out too hard but still need to feel alive. CP-FET51A grabs the peak, then gives the body back with Mix.
AGE CHARACTER
Choose how worn-in it feels.
Age moves the face of the sound from clean New to worn Vintage, so the compressor feels like a choice of texture, not just numbers.
PARALLEL MIX
Crush it, then bring the body back.
Use Mix to blend the compressed tone with the dry path. Drums can hit harder, vocals can sit closer, and bass can stay solid without becoming flat.
Now Available — The Finishing EQ
Noble EQ
Cuts that don't thin. Additions that don't clutter. A finishing EQ for vocals and mixes, now live on BOOTH with a launch sale.
FOR VOCAL
Bright, but never harsh.
Removing mud thins the voice. Adding air makes sibilance painful. Noble EQ removes the murk without thinning the body and adds brightness without making it harsh. The vocal core stays intact while the voice steps forward.
FOR MIX
Add without clutter.
Adding lows brings mud. Adding highs brings harshness. A hidden companion circuit linked to the four bands keeps your additions clean — what you boost stays musical, no matter how far you push.
FINISHING TOUCH
Cut without thinning.
EQ cuts can thin the sound. A transformer-modeling stage is tuned to help retain weight and character after the cut, so the last few dB feel more like finishing than fixing.
Flagship Compressor — Smooth Glue
AMBER VALVE COMPRESSOR
A compressor for vocals, instruments, and buses that need cohesion without a long setup. Variable ratio, dual detection, and tube tone work together as you raise Input.
TRANSFORMER MODELING
Saturation happens just by passing through.
Analog transformers sit at both the input and output. Signal passing through naturally picks up musical harmonic content — low end gains weight, high end stays clear. No adjustments needed. The circuit does the coloring.
DUAL DETECTION
Two circuits read every transient. Automatically.
Two detection circuits constantly monitor incoming transients. Drums get automatic attack delay to preserve punch. Smooth sources get fast response. Ratio also shifts in real time based on compression depth. There is nothing for you to set.
DOUBLE TUBE CIRCUIT
Double tubes add soft cohesion.
A compression stage and an amplifier stage work in series. Compression and harmonic generation happen together, helping disconnected tracks feel smoother and more unified.
New flagship pair.
Bonfire EQ + Bonfire Comp
A tone-first EQ and compressor pair for the moment when the take is good, but the sound still feels thin, far away, or unfinished.
IR Depth
Thin sounds get weight and air.
IR texture helps flat tracks feel less pasted on and more present in the song. Vocals, guitars, synths, and loops gain a sense of depth before you start over-processing.
Tone placement
Find the spot before you overthink it.
Use the EQ to decide weight, body, and shine quickly. Instead of chasing tiny corrections, you can commit to how the sound should sit in the song.
Closer Comp
More presence, less crushed.
Bonfire Comp adds density and punch without making the performance feel small. It is for the moment when the take is good, but needs to step out of the speakers.
AUTO ANALYZE / INSTANT MASTER
CalPochi MasterChain
Analyze, then finish in one window.
When you load your audio, INSTANT MASTER scans frequency response, dynamics, and problematic bands to build the first EQ-to-limiter starting point. The initial decision comes faster, and the direction of the master stays visible in one window. The moment you load it, the foundation of your master is already in place.
