LH Rubbing is a polyphony synthesizer app for iPad running on iOS 9.3 or later.
It sounds very analog.

There are three wave oscillators, one noise oscillator, two LFOs and one three type embedded filter (low-pass, hi-pass and bandpass).

Each wave oscillator can generate three kinds of waveform which are triangle, square and saw wave.

LFO can be attached to different modul for different modulation or control such as OSC Pitch, PW, Filter Cutoff Frequency, Filter Resonance and OSC Output Mixing.

The frequency and amplitude of the 1st LFO can be modified by the 2nd LFO.

Pitch, Filter Cutoff Frequency and Resonance can be controlled by the ADSR envelope generator.

The Keyboard Rubbing brings up vibrato while control the vibrato rate and depth.

Surprisingly Lush

This is actually quite a lovely synth. I've managed to program a number of useful patches/some surprisingly unique sounds. Definitely deserves more of my attention.

The responsiveness of knobs/buttons could use improvement. Some are overly sensitive, while others take several touches/long-presses in order to make the necessary changes. A value display while tweaking would be very beneficial, too.

Quite nice really

Many great features and the automation ball rocks. The rubbing part is like vibrato as you move up the piano key vertically, so ahead of the curve there. The is a hidden gem

Most expressive!

A fantastic addition to the studio. Very expressive playability and a modulation dream. Only request would be to add midi in/out and or audiobus compatability…

Thank you for this wonderful synth.
