Poly-Ana's voice architecture is a combination of the best features of the famous analog classics plus several new features for a total of 185 controls - see the feature list below. The GUI design aims to put every parameter just a single click away, with large, easy to grab knobs and switches that behave like the real-world items - there are no hidden drill-down menus so each and every control is prominently displayed where you can see it. Features:

• Maximum 12 note polyphony featuring unison, voice detune and a unique poly-unison mode.
• Three oscillators per voice.
• Two filters per voice: 12/24 dB/Oct, LPF/HPF, can be run in parallel or in series allowing for additional multi-mode capability.
• Filter Resonance Modulation.
• Stereo signal path throughout the voice. Poly-Ana produces dramatic stereo effects without using any tacked-on delay or chorus effects.
• All voice parameters always visible and accessible with a single click.
• GUI controls that work like the real-world items, like automatic knob detents and single-click toggles.
• Unique modulation routing scheme: All the power of modular without the tedious complications of using patch cables or a modulation matrix.
• Waveform "morphing" creates smooth transitions between oscillator waveforms beyond simple cross-fading.
• Waveform Mod automatically morphs oscillator waveforms.
• PWM for all oscillator waveforms.
• Noise Sync: Oscillators can sync to noise source as well as normal pitched tones.
• Two LFOs per voice with retriggering. Allows separate phase for each voice's LFOs.
• Full Host-Sync for LFOs with adjustable phase offset.
• Three ADSR envelopes per voice with adjustable curves.
• Two Modulation Mixers allow for complex combinations of modulation sources.
• Unique, oversampled voice engine.
• Quality control lets you reduce Poly-Ana's CPU power requirements while recording performances.

Changes since: v1.12

• Evaluation period reset.
• Receptor compatible.
• New SSE2 optimizations have reduced CPU usage to as little as 75% of version 1.00 on some platforms.
• Fixed bug in polyphonic mode where stolen voices weren't retriggering.
• Fixed some stability bugs in the editor.
• Added program name edit field, program select dropdown menu (click the program number), and program increment/decrement buttons to top of editor. Authorization controls have moved above keyboard and the "Auth" button has been removed. Simply hit "enter" or select any other control to confirm your key entry.
• Removed limit from high end of filter cutoff range. This allows the HPF mode to completely cut all sound now, rather than always letting some highs pass through as before.
• Voices in release stage now show in voice display. Changed behavior: Incoming MIDI no longer turned to automation events. Didn't prove useful as a feature and can cause conflicts in some cases.
• Fixed bug when handling "duplicate timestamped" MIDI events of the same type. In this case the last received duplicate event will be used now. Fixes pitch bend and modulation errors from some host/controller combinations.
• Fixed a long standing bug relating to oscillator sync that was causing Poly-Ana to get "sick" under certain, rare conditions. (Hosts that make random patches were very good at casing this.) Poly-Ana should no longer have "poison patches".
• Fixed another oscillator sync related bug where sync was internally turned off after bypassing/resuming even though editor panel still showed the correct setting.
• Changed the method Poly-Ana uses to find its .dll location, may help users who were having trouble loading the custom background Poly-AnaBG.png
• Restored the upper cutoff limit on the filters, prevents a sudden jump in volume at higher cutoff frequencies (well above Nyquist). This will fix any programs that may have sounded different in version 1.12.
• Fixed crash problem when closing editor in certain poorly behaved hosts.
