Read full description

ThermVoltTube is an asymmetric triode distortion processor for iPhone and iPad. Use it as a standalone audio app or insert the included AUv3 effect in a compatible host such as GarageBand. Its nonlinear core models a tube preamplifier with selectable 12AX7 and 12AT7 behavior. Asymmetric plate transfer, grid conduction, Miller capacitance, plate impedance, operating temperature, tube bias, and selectable plate-supply behavior create a response with prominent even-order harmonic content. FEATURES - Selectable 12AX7 and 12AT7 tube behavior - Asymmetric triode transfer and grid-conduction modeling - Temperature and tube-bias controls - Selectable 200 V / 300 V plate-supply behavior and sag - Instrument and line input modes - Boost stage - Adjustable gain, high-pass filter, tone, drive, and output - 2x and 4x oversampling modes - Standalone iOS/iPadOS app - AUv3 audio effect for compatible hosts TRY BEFORE UNLOCKING The app provides 10 minutes of full-featured active use. Demo time advances only while the standalone app or AUv3 effect is actively being used. After the allowance is used, audio processing is disabled for 24 hours. A one-time, non-consumable In-App Purchase unlocks unlimited use in both the standalone app and AUv3 extension. Restore Purchases is available in the standalone app. ThermVoltTube is designed for guitar, bass, synthesizers, keyboards, and other sources that benefit from asymmetric tube-style saturation.

It gives you control over how audio is sliced, mapped, and played, so you can turn raw material into something musical. Each slice can be adjusted, You can edit the timing, trim edges, and control how the sample behaves. This makes it easy to clean up recordings or reshape them into something new. The pad interface keeps everything simple. Tap to trigger sounds, build rhythms, and experiment freely. It’s designed for quick interaction, so ideas come together quickly. The Sampler also helps you easily create advanced rhythms - use note repeat to create rolls, patterns, and rhythmic variations in real time. Layer multiple samples to build depth and texture. Effects are built in. Shape your sound with tools like EQ, compression, delay, reverb, distortion, and more. Apply them directly and hear the result instantly. This lets you move from raw audio to a polished sound without leaving the app. Recording is part of the workflow. Capture your performance, layer ideas, and build something more complete over time. Each take can be refined and reused. Everything stays organized and ready to use. You can export your samples, recordings, or full ideas and move them into other tools or share them.
