File Release Notes and Changelog

Release Name: 0.1.0

Notes:
Overview of changes in version 0.1.0, released April 12 2000
============================================================
* All ingredients for a monophonic cult synth:
  - Square/sawtooth oscillator (not yet bandlimited)
  - 4-pole all-pole low-pass filter
  - ADR envelope generator
  - 16-step pattern sequencer
* Butt-ugly GUI with controls borrowed from TB-303:
  - waveform select
  - oscillator tuning
  - filter cutoff frequency
  - filter resonance
  - envelope modulation amount
  - envelope decay time
  - accent amount
* Real-time audio output on Linux and theoretically also IRIX and Solaris
* LOT of debugging garbage printed
* Initial release

	the "tempo" text label

	callbacks

	* src/main_window.cc (poll_toggle_states): make note buttons

	line args

2000-03-01  Jarno Seppänen  <jams@cs.tut.fi>

	* src/main_window.{cc,hh}, src/mono.cc: converted to use Gtk-- 1.1.8

	from Gtk_Button to Gtk_ToggleButton and added sequencer polling to show
	the sequenced notes on each step

	* src/engine.cc (Msyn_Engine): added sample_rate and latency_time as
	constructor arguments

	* src/engine.cc (set_latency_time): now assures frame length is an
	integer and rounds frame duration (latency) upwards accordingly

	* src/audio_output.cc: moved {open,close}_audio to initialize/finish
	functions

	* src/mono.cc: Hardcoded sample rate and latency are now here

	* src/audio_output.cc, src/engine.cc: Removed hardcoded sample rate
	and latency (frame size) parameters

	* src/sequencer.cc, src/engine.cc, src/main_window.cc: added initial
	sequencer functionality

	* src/main_window.hh: fixed misspelled 'button_eis' to 'button_e'

2000-01-24  Jarno Seppänen <jams@cs.tut.fi>

	* src/audio_output.cc, src/engine.cc: got audio output working
	using libaudiohw/OSS!

	* src/audio_output.cc, src/engine.cc: hard coded the sample rate
	to 44100 Hz

	* src/filter.cc, src/engine.cc: fixed filter stability problems

	* src/mono.cc: now start thread from main() instead of the engine
	constructor

	* src/main_window.cc: now initializes engine knob values

	* src/filter.cc (execute): normalized filter peak gain to approx. unity
	instead of allowing the amplitude to rise
