Thirdnail ,

Wish I would have downloaded ages ago! Tons of control, great sound...

This little synth allows you to manipulate a sound in so many ways. Guys, if you like crawling in a hole with an synth and tweaking each preset (or jump off point) and saving you sound creation as a new preset, then you will be angry that you didn’t download this app when it first came out.

I guess I either A: over looked it. B: didn’t see enough reviews, or C: this app became free and it popped up on the iStore near the top.

Download this instrument, you will not be let down! I just hope the developer will be working on new synths in the future!

Aka monkey dope ,

Music Mogul ,

Can Synth software developers make Audio Demos?

Please,,,, Can the Developers Of All these cool and Not So Cool Apps provide the potential customers with an Audio demo Of what the synth, drum machines, or other sound generating apps Actually sound like with a simple audio clip embedded in their ads?

When a musician wants an instrument or software and really has to make a decision based on budget, hardware compatibility, ease of use, etc.,they go to a music store or website to Hear and see the products.

It’s a common practice here on the AppStore for developers to Say how great the software is and show stills of the screen graphics, or short video clips, However, if there was more companies that provide audio demo for the customer to hear, it would make it easier, fast and perhaps even more profitable for the developers and Apple.

Thanks In Advance
