USER INSTRUCTIONS FOR SY-EDIT

User instructions for SY-22 and SY-35 voice editor

SY-22 and SY-35 voice editor for Atari ST, Written by Richard Hanson, (C) 1995 (V1.0), (C) 1996 (V1.1)

1. INTRODUCTION

This program, SY_EDIT.PRG, was written to allow the editing of SY-22 voices, and extended to include the SY-35 which has identical voice architecture and only differs with some of the available AWM samples. There are a number of editable parameters that can only be accessed using MIDI System Exclusive: It does not allow editing of Multi set-ups, however, since these can only be accessed in All Voice/Multi dumps, and they are therefore more easily editable from the synth’s front panel. Voices can be stored and loaded from disk. The file format is compatible with that for Steinberg’s Satellite desk accessory.

Note that, for the most part, the synthesizer front-panel numbers for various parameters can be forgotten, since they are sub-sets of the available MIDI values, e.g. on the front-panel levels go from 0 to 99 whereas over MIDI they go from 0 to 127.

2. USER INTERFACE

The user interface is not standard GEM, but it is easily understood. The mouse works as usual, with the left mouse button decreasing values and the right button increasing values. Holding down either of the SHIFT keys when changing a value changes the value in steps of ten. All displayed settings are editable with the except for the envelope displays in each Element. The display is divided into nine areas, described as follows:
  1. Title;
  2. Element Area A;
  3. Element Area B;
  4. Element Area C;
  5. Element Area D;
  6. Voice Common Area;
  7. Vector Area;
  8. Edit Area which displays the currently selected item (elements A to D, Voice Common or Vector);
  9. Button Area which has a row of buttons along the bottom of the display that have the following functions:

2.1 Element Area

In each Element Area, the following parameters are available:
  1. velocity response: This is the line that appears next to the element name.
  2. element level: This parameter graphically displays the volume of the element. Range 0 to 127
  3. pan position: This parameter graphically displays the pan position of the element. Pressing the left mouse button shifts the pan position left and the right button shifts it right.
  4. envelope shape: This is a graphical display of the envelope of the element. For the FM elements, two envelopes are displayed, the thick line being the carrier envelope, and the broken line being the modulator envelope.

    2.2 Voice Common Area

    In the Voice Common Area, the following are available:

    2.3 Vector Area

    The Vector Area, the following are available:

    2.4 Edit Area

    The contents of the Edit Area depend on the currently selected edit mode. When the program starts up, it is in Global edit mode. The modes are explained as follows:

    2.4.1 AWM Edit (Elements A and C)

    When elements A or C are selected for editing, the following parameters are available to be edited:

    2.4.2 FM Edit (Elements B and D)

    When elements B or D are selected for editing, the following parameters are available to be edited:

    2.4.3 Edit Voice Common

    When Voice Common data is selected for editing, the following parameters are available to be edited: FM Waves:

    2.4.4 Vector Display

    When Vector information is selected, a graphical representation is displayed for the X and Y elements for both the level and detune vectors. Note that some of the detail is missing in order to fit all four vectors on the display, however it is still more detailed than on the synthesizer’s front panel! Note also that for two element voices (A-B) only the Y values are relevant. No parameters can be edited in this display.
