## LH Rubbing Description
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.

## LH Rubbing Reviews in United States

### ***** "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.
-- Fallingapples, 2022-01-08

### *---- "???????????????"
Works with NONE of the music apps I have.
-- DJhc504, 2021-12-09

### ****- "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
-- Oceans in space, 2019-01-21

### ***** "I like it"
Another important tool in my arsenal of sound creation.
-- kashleeee, 2016-09-23

### ***** "Nice!!"
Nothing but a little awesomness here.  Very playable synth with great sounds.
-- Hydra vein, 2014-12-04

### ***** "Fat and original"
This is another one of my favorite synths that can cut thru or wobble or create wandering evolving textures. It has an awesome interface with a killer rubbing effect(a kind of automation). This one deserves your time and is stable.peace christo
-- MuzikalaChristo, 2014-09-16

### ****- "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.
-- Selectedacre, 2014-05-08

### ****- "Keep it up!"
I get it... Long ago I owned a CAT by Octave and using this took me right back to those days in the damp basements working with a machine that had limits, but in many ways was more expressive than much of what is offered in the digital world today. This is a CLASSIC synth interface and can teach novices a few things about synthesis because it is exposed and simple. It also sounds pretty cool! Yes, it needs some work, (navigating patches is brutal) but my hope is that the developer is just getting started. 

Also, about the name... Try rubbing the keys... Heh. I am not sure if this is a method for controlling modulation I will embrace... But 50 points for originality! (I wondered why the thing that looked like it was in the place the mod wheel should be didn't do anything, heh). 

Pick it up and play with it... It's cheap, fun, and nostalgic.
-- Murdock Scott, 2013-06-18

### ***-- "Interesting synth app"
The half screen of help shows buttons that I cannot find in the app. The file section you can't just touch the one you want to load to select it You have to use the 'Previous' & 'Next' buttons. How PC'ish! There isn't a key hold button. All synths should have that in my mind as it adds flexibility for playing live. Hopefully there will be future updates for this app.
