## What is iSyn Poly?

iSyn Poly is an electronic music studio for use with Apple iPad. iSyn Poly places an unbelievable number of features including three studio-quality, fully programmable virtual analog synthesizers and a drum machine packed in just three different screens on your iPad ! 

Each synthesizer is a full-featured analog modeling synth with three oscillators, a classic 24 db/oct ladder-style lowpass filter, independent filter and amp envelope generators, and full modulation routings. With our 10+ years of experience with analog simulations you can expect some serious sound easily covering all those fat frequencies so prevalent in modern production. 

iSyn Poly also includes a sample playback-based drum machine with seventeen kits, each containing eight samples. Drum samples include 808, 909, modular synth drums and numerous 80's drum machines. Volume, pan and decay time are individually adjustable and pitches are tunable over a wide range for crazy effects.

The full fledged sequencer let you arrange complete songs and can record the notes and controller movements  of your performance. The unique gesture oriented user interface makes it ideal for live editing of notes and automations.

With the Apple iPad Camera Connection Kit you can use a CoreMIDI compatible MIDI Keyboard to control iSyn Poly.

iSyn Poly is developed by VirSyn with content from audioMIDI.com.

### 5/5 — I love this but-

*2020-03-20*

Import export is fatally flawed please Virsyn tweak this in an update, just this much and my love will be free once again to express itself with this fine tool 
(I actually contacted the deliver about this, and his response was not encouraging I think because the code was done in part by people no longer in the firm)

### 4/5 — ISyn poly .....

*2019-11-06, version 2.3.0*

Great synth,
Not too many presets but lots of knobs...lol
Would be awesome as AUv3, but recording into Cubasis isn't a problem as long as you remember to change midi channels for each synth, (mono 1 mono2 poly, & drums) then remember to change back to midi ch 1 to use your other AUv3s......
Great built in drum machine, not a lot of drums, could do with an update with more sounds and drum kits to keep up with more modern/up to date synths, but overall some good sounds...
🙏🙏

### 4/5 — Classic still

*2019-01-05*

This is old but good, with 3 separate units to jam together with. The drum machine is just the normal ones but the synths can be clean and analog sounding.

### 5/5 — Works amazingly now.

*2017-10-11, version 2.3.0*

I used to have some issues with this. But now it's running real smooth.

### 3/5 — Virsyn are usually great devs but...

*2016-04-15, version 2.1.2*

...this isn't a great app. Just feels and sounds poor quality compared to Virsyns other apps.

### 5/5 — Excellent, I say buy it now.

*2015-04-19*

Picked this right up and laid a dope drum beat on accident basically. That's besides the tons of synth presets. Everything is tweakable like crazy too. Easy sequence and song setup. I've had iVoxel forever and that's excellent too. The best part though is this is only $1.99. That's Insane!!!

Keep Tera Synth at $10 I'm gona buy it this weekend and pick up Cube Synth as soon as it drops a little. I'm sure it's worth it now lol but hey lol

### 4/5 — Love it but...

*2014-09-16*

...It could use quantization and swing control on the drum pads.

### 4/5 — Excellent Synth

*2014-03-02*

Just bought this at the sale price
and it's an outstanding value.
Has great sounds which are easy to modify
and with the built in sequencer and drum
machine you can create to your hearts content.
This is an app I know I will be using.

### 4/5 — definitely worth the money!

*2014-03-02*

Terrific synth and drum machine.

### 3/5 — Could be better

*2014-02-23*

Nice sounds, other apps by dev team are superb,
This one does lack. Namely selectable midi ports for input and sync,wist.
Keep it up devs
