New Favorite Instrument!

I use the iMS-20 on my iPad 2. I have several other synth apps, but none I have found offer such a vast combination of sound generation possibilities. This app does it all, if you take the time to learn about this program. The info in the manual is great for beginners, too.
With enough knowledge, one can emulate virtually any musical instrument and produce an entire composition from rhythm to lead.
This app offers so much for so little, compared to prices of physical synth machines. You can even utilize dual kaossilator pads or a virtual keyboard for live performing or recording.
If you make music or are interested in learning how to create electronic beats, this app is a must have. As a newcomer to synthesis, the challenge of understanding, alone, is enough to occupy my focus for hours.
My favorite aspect to using this app, are the results I see while merely using the app. Becoming familiar with the array of variations and manipulations available will perhaps keep me entertained and learning for years to come!

The first real synth I owned in the mid 80's was a MS-20

Before I bought it I learned the basics with a modded Casio, a Roland string machine & TB drum machine topped off with a space echo. The MS-20 was a game changer. Exponential leap forward. Why did I sell it? A long trip to explore old sites in Mexico & Guatemala. It was worth it. I got this app right after it came out. Life got busy & I never dug into it. Then I got Gadget. Really intuitive & so many choices. After taking Gadget to most of the places I wanted to I've circled back to iMS-20. Wow. Just wow. Through big speakers the emulations are fat & gritty. It's the real deal. When I first got this app I got so obsessed with patching & tweaking in it I completely ignored the "drums" righteous step sequencer, & boss Kaos controllers. If you get this don't be a dope like me. Digging around in it's guts & corners there's solid gold. Korg nano key studio plays real nice with this app.

Super Sick MS i-Synth! GIVE US Midi SYNC!!!!!

Awesome sound, one of the 1st apps for my iPad Air 1. Awesome sequencer, Drums would be IDEAL if they could be tweaked LIVE.... However this app would rule if it had Midi I/O. How hard can it be to add this feature? Every other iSynth has it...
I have had iMS20 for over a year, still use it, glad to see it was recently updated for bug fixes etc, ya forgot one feature ....THE Midi!!! Sorry, WIST doesn't cut it... It's toy technology. If I could Sync this w/ Hardware I would add it to the table and not just record 4 bar loops for other apps/gear to play with. I ain't buying the hardware, the beauty of this is the state saving. I run the out into an analog filter. Anyway, big fan never the less. Korg rules - SD4000 delay, Toneworks, Microkorg, (2) ElectribeR, EMX, monotron Delay... All that.
Sup' son?
