Foreword
After several years of preliminary work and the great passion for
synthesizers, the basis for the MD900 was created. It is
characterized by its powerful stereo sound, its analog charm
and an intuitive operating concept.
I would like to thank you very much for purchasing the MD900.
For all those who only read through this manual I hope to have
awakened the curiosity for this extraordinary synthesizer.
On the subject of reading manuals
We have tried to develop a synthesizer which is intuitive to use.
Many of the terms are classic and familiar to most, but we still
recommend reading this manual. Especially for the operation on
the panel with maybe not so obvious functions.
For a better overview you will find a schematic representation
of the respective section in the chapters. All names like knobs,
sliders and buttons are printed in BOLD in the manual and
correspond to those on the MD900 panel. Furthermore, the
menu items of the touch display are shown in BOLD CURSIVE in
the manual.
Note
A lot of care has been taken in the preparation of this manual to
exclude errors and inconsistencies. We apologize in advance for
any errors. Mayer-EMI makes no warranties of any kind with
respect to this manual, except those required by trade laws.
The content of this manual is subject to change without notice.
This manual may not be reproduced, in whole or in part,
without the permission of the manufacturer.
