Charlatan

2.0 Final (2015-06-05)

Fix loading of 1.x presets
Fix popup menus with multiple monitors
Make Amp envelope sustain parameter logarithmic
Fix old presets (LFO Wave), add some new ones
Reduce pitch drift

2.0 Beta 3 (2015-05-03)

BUGFIX crashes on AMD systems

2.0 Beta 2 (2015-05-02)

BUGFIX not loading in some hosts
BUGFIX note hanging after switching voice modes

2.0 Beta 1 (2015-05-02)

completely rewritten DSP engine resulting in roughly 50% (!) CPU savings in polyphonic mode
unison mode with upto 7 voices and stereo spread. Even with 7-voice unison, CPU usage is very bearable
major GUI overhaul
additional LFO waveforms
stereo noise
some more presets
mostly compatible with presets for Charlatan 1.x (*)

Noise source now separate from Osc 1
Osc 2: narrow pulse wave
LFO: extended rate range
GUI update
BUGFIX: potential crasher
more presets

Ring modulator: perform DC blocking at output rather than inputs
envelopes: reduce minimum decay/release time to 4ms
less excessive smoothing of filter cutoff parameter (adaptive to audio buffer block size): allows more accurate automation
GUI: change color of version text to light gray (for people changing background color)
minor filter tweaks
minor envelope tweaks
support Cockos VST extension to display correct parameter values in automation envelope lanes in REAPER
compiled with latest version of Microsoft(R) compiler: possibly improved Windows(R) XP compatibility

New feature: LFO sync to host tempo
new feature: set LFO phase at song start (applies also to non-synced LFO rates!)
new feature: DCO ("Digitally controlled oscillator") switch (see readme.txt)
new feature: Osc1 shape parameter now applies lowpass/highpass filter to noise source (center position yields white noise). Note: no shape modulation for noise
improved filters: better solver for nonlinear zero-delay feedback (credits to Teemu Voipio aka mystran), nicer saturation characteristic
ATTENTION: Patches with high resonance could sound slightly different than with previous versions! Adjustments of resonance, oscillator levels and master volume might be necessary.
improved UI graphics
Legato mode: only retrigger LFO delay on non-legato notes
BUGFIX: reset all voices when playback starts
some more presets

Jet another revision of the 4-pole ladder filter implementation. Placement of nonlinearities is now correct wrt. the original circuit
new switch 2OCT for Osc2: double detune range (+/-2 octaves)
90 degree phase shift of Osc2 square wave wrt. Osc1 (only when sync is inactive). Emulates behavior of sub-oscs of Roland synths.
if Osc1 is set to noise, the ring mod input of Osc1 is now the rectangle signal rather than noise.
Reduced max. filter key tracking from 200% to 100%. 200% just isn't useful.
BUGFIX: LFO delay parameter was completely hosed (10x the displayed value!)
BUGFIX: handle LFO delay time on samplerate change
doubled max. LFO delay time (10s -> 20s)
minor tweaks'n'fixes

BUGFIX: corrected placement of nonlinearities in 4-pole lowpass filter. Mainly noticable with high resonance.
Filter key tracking: account for glide and pitch bend
introduced slight pitch tuning error of voices in polyphonic mode
Detune parameter is now nonlinear to make it easy to dial in small values
minor tweaking of presets

Handle MIDI program change
BUGFIX: aliasing artifacts of triangle oscillators at very high pitch
smoothing of filter cutoff parameter to eliminate artifacts when doing fast manual sweeps
BUGFIX: regression which broke compatibilty with older hosts such as Cubase SX
some more presets (based on banks from KVR member Alvfaria)
