What are the key synthesis features?

It features a 4 VCO architecture with two voice layers, each containing two VCOs. You can choose from 4 synthesis engine types, utilize 36 analog VCO waveforms with pulse width modulation, and employ full stereo and mono unison modes for each VCO independently. It also includes noise and subharmonic oscillators, a unique ring and self-modulation matrix, and high-quality non-linear filters with over 30 types.

How much does TB Flowtones cost?

TB Flowtones is a paid application. Licenses acquired for one platform are not compatible with other platforms.

What are the system requirements for the AUv3 plugin?

The Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4, or later models. This ensures optimal performance and compatibility for the advanced features of the plugin.

What kind of effects are included?

The app includes pro-grade effects such as studio-quality reverb, delay, and chorus. It also features a unique formant filter for vocal character, analog and digital distortion/bit crushing effects, a master equalizer, and a peak limiter for final mastering touches. A non-linear power supply simulation is also included for authentic interaction between notes.
