TONVERA PROMETHEUS
Neural amp modeling
PROMETHEUS powers the amp modeling in APOLLO, ATLAS and ZEUS. Built on neural networks and machine learning, it learns how an amplifier shapes sound, bringing its tonal character and response into your playing.
Powered by neural networks
Machine learning studies an amp’s sound and response, from the shape of a note to the way it breaks up as you dig in.
Neural networks model the relationship between your playing and the amp’s output, shaping gain, dynamics and tonal detail.
Bring neural amp modeling into your rig. Explore tones, shape the surrounding effects and keep your focus on playing.
PROMETHEUS uses models learned from audio to recreate amplifier behavior. The focus is on tone and the response to your touch.
From guitar in APOLLO and bass in ATLAS to custom signal paths in ZEUS, PROMETHEUS brings neural amp modeling into your creative workflow.
Professional Sound Technology
Independent software for musicians — built around tone, signal routing, and a workflow that gets out of your way.
Community
Browse presets shared by musicians around the world. Find your next tone, share your own creations, and rate your favourites.
Formerly Noah Rigs
Powered by PROMETHEUSGuitar amp modeling, cabinet shaping and effects, in one complete signal chain.
Inside APOLLO
Start with four amp channels and eight voicings, then set the gain, tone stack and power amp response to match your playing.
Blend cabinet captures and adjust mic placement before shaping the final response. Put dynamics and drive before the amp, add movement and space after it, and save the complete sound as a preset.
The APOLLO signal chain
Explore the amp, cabinets and effects in detail. Each module gives you a different way to shape the tone and response of your rig.
01Amp
Powered by PROMETHEUS
APOLLO’s four channels with A/B voicings cover clean, crunch and high-gain sounds. PROMETHEUS neural amp modeling gives each voice its character and response.
Choose a channel and voicing, then balance gain, the tone stack and power amp response. Adjust the sound while playing to hear how the amp responds to light picking, stronger attacks and sustained notes.
02Cab
Shape the sound after the amp with cabinet choices, mic placement and response controls. Find the balance of body, focus and top-end detail.
Choose from four cabinet slots and adjust the microphone position. Use low and high cuts to control the extremes, then set the output level to balance the cabinet with the rest of the rig.
03Pre FX
Gate, compression, boost and overdrive prepare the guitar signal before it reaches the amp. Use them for a controlled clean sound or a more driven response.
Set the gate around the pauses in your playing. Adjust compressor attack and release to control the note envelope, then use boost or overdrive to change how strongly the amp is driven.
04Post FX
Build the sound around the amp with modulation, stereo delay and reverb. Add subtle width, rhythmic echoes or a longer ambient tail.
Choose the modulation character, set delay timing and feedback, and shape the reverb with size, pre-delay and damping. Balance width and mix so the effect supports the part without obscuring the original attack.
05EQ
Ten graphic EQ bands let you adjust body, presence and brightness. Low and high cuts keep the final sound focused.
Make broad tonal adjustments with the sliders, then use the low cut to reduce unwanted rumble and the high cut to soften excess brightness. Match the output level when comparing different EQ settings.
06Filter
Pitch shifting, auto wah and the Vocalizer add another layer of expression. Move from a familiar guitar tone into filtered or voice-like textures.
Use pitch processing to change the register and auto wah to shape movement in the signal. Explore the Vocalizer’s Voice and Hachimi modes, then balance the processed sound against the guitar part.
07Tuner
Check tuning within the rig, with a clear note display and pitch position. Stay in the same workspace between parts or takes.
Play a note and follow its position against the tuning reference. Make the adjustment at the instrument, then return directly to the signal chain without opening a separate tuning app.
Releases
Runs as a standalone app or plugin.
Formerly Noah Bass
Powered by PROMETHEUSBass amp modeling with precise dynamics, cabinet control and a dedicated signal chain.
Inside ATLAS
Choose a Clean, Vintage, Rock or Modern bass voice. Use compression and drive ahead of the amp to shape attack and weight while keeping the instrument's character.
Blend the cabinet path with a direct signal, adjust mic position and refine the result with graphic EQ and low and high cuts. Save the full setup as a preset for the next session.
The ATLAS signal chain
Work through the amp, cabinet, dynamics and EQ, with tuning built into the same workspace.
01Amp
Powered by PROMETHEUS
Clean, Vintage, Rock and Modern voicings give your bass distinct starting points. PROMETHEUS neural amp modeling shapes their tonal character and playing response.
Choose the voice that suits the part, then balance gain and tone around the instrument. Listen to both the note’s attack and its sustain as you move between a cleaner foundation and a more driven sound.
02Cab
Combine cabinet character with the direct bass signal. Adjust mic position and response to balance low-end body with the definition of the original instrument.
Set the cabinet and microphone position, then blend the direct signal back in as needed. Use the response cuts to control the extremes and compare the result with the bass part in context.
03Pre FX
Compression, gating, boost and drive work before the bass amp. Shape uneven peaks, add sustain or bring a firmer edge to the part.
Adjust compressor threshold, ratio, attack and release around your playing. Use the gate for quieter pauses, then add boost or drive to taste. Check sustained notes as well as short, percussive attacks.
04EQ
Ten EQ bands and low and high cuts give you control over bass weight, midrange definition and upper harmonics.
Adjust the low bands for weight, the mids for note definition and the upper bands for attack. Use the cuts to manage the extremes, and compare changes at a similar listening level.
05Tuner
Tune the bass within the same workspace, using a clear note readout and pitch position before rehearsal or recording.
Let each note settle and follow its tuning position. Adjust the instrument, check again, and return to the amp and effects with no separate tuner window to manage.
Releases
Runs as a standalone app or plugin.
Formerly Noah Stage
Powered by PROMETHEUSA modular effects workspace for building, connecting and performing with your own signal chain.
Inside ZEUS
Place amps, cabinets and effects on a visual canvas. Connect modules in the order you need and create parallel paths when a single chain cannot express the sound.
Sync tempo-aware effects to a manual or host BPM, watch input and output levels, and save the complete graph as a preset. A separate tuner view stays within reach when it is time to play.
The ZEUS workspace
Choose the modules, define the connections and save the complete setup. Every stage remains visible on the canvas.
01Signal routing
Powered by PROMETHEUS
Connect amps, cabinets and effects across a visual canvas. Create parallel paths and see how each part of the rig reaches the output.
Place modules where you need them, connect their inputs and outputs, and compare different orders. Use parallel routing to combine contrasting treatments, then check the complete signal path before saving the setup.
02Module library
Browse amps, cabinets, drive, dynamics, EQ, pitch, modulation, delay and reverb. Build the chain around the sound you want to make.
Open the module browser, choose a category and add a processor to the canvas. Combine the modules in a simple chain or a wider arrangement, with the controls for each processor close at hand.
03Tempo and levels
Set the project tempo and sync compatible effects to the pulse. Input and output meters keep signal levels visible while you work.
Choose the BPM for the part and use sync on tempo-aware modules. Listen to the repeat pattern against the rhythm, and watch the input and output meters as you balance the complete rig.
04Presets and tuning
Save the routing and module settings as a preset. Recall a sound and check tuning from the same performance workspace.
Name and save the complete setup after balancing the chain. Recall it for the next session, make the adjustments the part needs, and use the built-in tuner before you start playing.
Browse the amp, cabinet, drive and mastering libraries, explore synth modules, and check the tuner.
Releases
Runs as a standalone app or plugin.
