Yamaha brings us Synth Book, and it's so much more than a book!

Well this was a bit of a surprise ...

Yamaha celebrates the 40th Anniversary of Yamaha Synthesizers with the Yamaha Synth Book!!!!!!!!!
This app features a complete history of Yamaha Synthesizers, an integrated virtual analog soft synth, and serves as a portal to Yamaha’s online synth communities.

5 FEATURES:

• HISTORY features detailed, “behind the scenes” information about the 40-year design and development history of Yamaha synthesizers. This fascinating historical accounting of the technological breakthroughs behind some of the most innovative, musical and successful Yamaha synthesizers is a must-read for all synth fans.
• AN2015 features virtual analog modeling like the AN1x. It also features a drum part that can keep the beat going while you perform and control the main synth part.

Use case 1: Enjoy it as a standalone iOS app!
There are 2 modes available, SYNTH mode and Drum mode that work at the same time, e.g. when drum phrase is playing, Analog sound can be selectable and playable with the drum phrase, and vice versa without stopping ongoing music.

Use case 2：Use it with a MOXF as an external tone generator!
When connected to the Yamaha MOXF Music Production Synthesizer (OS version 1.10) using the Lightning to USB Camera Adapter by Apple, the MOXF becomes the MIDI/Audio interface for the iOS app creating a very powerful music production system.
