Lowtone Edit is an Android voice editor for ToneBoosters Lowtone bass synthesiser. It also functions as real-time synthesiser on your Android device!

Create modify and fine tune your patches on the go. Use the internal piano keyboard to play and listen. Integrate catchy sequences using the integrated sequencer. Create a library of patches on your mobile device.

Use your new patches in your music production studio by exporting your patches and import them onto the desktop or iOS version of Toneboosters Lowtone.

The free demo version has patch saving and export disabled. For the price of a cup of coffee you can unlock saving and export of patches with a simple in-app purchase.

About TB Lowtone:

TB Lowtone is an innovative bass synthesizer app featuring three analog-simulated voltage-controlled oscillators with a large variety of waveform algorithms continuous pulse-width modulation (PWM) Frequency Modulation (FM) and oscillator hard sync complemented by a voltage-controlled noise synthesizer parameter modulation a re-designed non-linear voltage controlled filter.


TB Lowtone is the world's first bass synthesizer featuring loudness-domain harmonic synthesis creating deeper more consistent and production-ready bass sounds compared to conventional synthesizers operating in the (linear) amplitude domain.

TB Lowtone also features a smart randomizer that generates new patches with a single click and which learns from the patches you have already created to generate new personalized patches!


Loudness-domain synthesis
Loudness perception of tones and harmonics is known to be highly non-linear and intricately frequency and level dependent. Equal loudness contours or Fletcher-Munson curves demonstrate this drastic effect for sine tones which is especially relevant for low frequencies.

The loudness of a synthesizer bass note and all its individual harmonics will therefore depend strongly on what note you play on your synth's keyboard.

To overcome the resulting inconsistencies in loudness and timbre TB Lowtone features innovative loudness-domain synthesis algorithms that adjust each harmonic individually to compensate for loudness deviations across frequency.


Modulation and FX
TB Lowtone provides two extended low-frequency oscillators (X-LFOs) featuring a wide range of waveforms. The LFOs can be beat and key synced with a configurable onset delay and a specific number of cycles to run.

In addition a conventional ADSR envelope with configurable onset delay is provided. To top if all off a gate editor designed to quickly put together modern production modulation patterns is available as well to modulate a range of VCO VCN and VCF parameters.

Reverb chorus and delay effects and a high-quality peak limiter are provided to produce production-ready sounds.
