LH Rubbing

LH Rubbing is a polyphonic synthesizer app for iPad, delivering rich analog-style sounds. It features three waveform oscillators, one noise oscillator, two LFOs, and a multimode filter with three modes: low-pass, high-pass, and band-pass. Each waveform oscillator offers three waveforms: triangle, square, and sawtooth. The LFOs can modulate various parameters, including oscillator pitch, pulse width, filter cutoff frequency, filter resonance, and oscillator output mixing. The second LFO can modulate the frequency and amplitude of the first LFO. Pitch, filter cutoff frequency, and resonance can also be controlled by the ADSR envelope generator. The unique Keyboard Rubbing feature lets you create vibrato directly from the keyboard, controlling both its rate and depth.
