1: Introduction

The SuperMAX+ is a very powerful option board that provides increased memory
and greater control of the legendary Yamaha DX7 synthesizer.

SuperMAX Features

 Memory Expansion: Sixteen banks of 32 patches equaling 512 patches
total. Two banks of "factory" patches are included.
 Voice Stacking: You can stack and detune two, three or four voices of the
same patch. You then have a choice of 16x1, 8x2, 5x3 or 4x4 polyphony.
The detuning can provide chorus effect and/or chording and/or octaves
(for example).
 Voice Delay: Add additional notes of the same or different pitch, delayed
from 10ms to 10s for each note you play.
 Arpeggiator: You can predefine 32 types of arpeggiation over part or all of
the keyboard.
 Sound Creation and Morphing: New patches can be developed and
existing ones can be selected live by pitch/mod wheel, velocity, random,
etc.
 Temperament: You can predefine 4 different keyboard tunings.
 Programmable master volume.
 Programmable keyboard zones, MIDI zones and MIDI channel.
