??? synthesizer (INCOMPLETE)

It makes sound, but doesn't work yet as expected.

cws80's Issues

Parameter setting problem

1. Click INIT
2. Go to DCA2
3. Click ENABLE to set it ON

Bug: it's not enabled

4. Click ENABLE twice to set it OFF and ON

DCA2 is enabled

Badly adjusted filter

Even at the setting 0, the VCF has considerable impact which it shouldn't.

(Make frequency response analysis)

Handle Windows unicode

• fopen
• dlopen
• opendir

Completing a basic implementation

• fixing graphics problems of the GUI.
  The program was switched to CPU-based rendering, resolving the issues.
  The DPF submodule was switched to my cairo branch which is not merged yet in the upstream.
  (fixed on request of @farvardin)

• the drop-down boxes cannot display a full list when there are too many elements: programs, waves. I thought about breaking it in numbered submenus (1-10, 11-20, and so on)

• envelopes broken in the simplest instruments.
  I expect timbres to sound considerably better after I fixing this.

• oscillator phases must be reset in sync on a new note

• have semi-automated fidelity comparison against original sound.
  There is SQ8L as Windows VST, but need to figure out the instrument format for automation.
  Also MAME has SQ80 as machine (tag "not working"), low-level emulated. (might prove helpful in reverse engineering)

• replace ROM waves with free sounds
  Sound is stored is Ensoniq ROM chips and it's probably a problem for redistributing, unless recreating it based on replacement sounds.
  (on the other hand, Ensoniq no longer exists, and there exist other software using this data)

Font textures not displayed right

Check the handling of creating and painting the font atlas with openGL.

It does not display correctly on software GL (LIBGL_ALWAYS_SOFTWARE=1) and on some machines.
