Surge

Fixes:

OSX AU: fixed bug that prevented surge from passing the AUVAL tool in snow leopard. As a result, it wouldn't load in Logic.

OSX VST: fixed crash caused by snow leopard no longer allowed setting the SSE control register directly.

Sustain pedal (and other CC controllers) now works correctly for scene B

The ringmod 2&3 signal in the osc mixer wasn't stereo with the wide filter-block configuration.

Loading the preset "delay pops 4" no longer causes a crash

The step-sequencer couldn't retrigger envelopes when the modulation output of LFO1 wasn't used.

[PC] When importing wavetables using wav-files they can now be up to 1024 samples long.

[OSX] Reduced threading priority for patch switches, which should eliminate glitches on patch-changes.

[OSX/PowerPC] Fixes for DSP-bugs in filters, wide-mode, oscillators & oscillator mixer.

Filters
The new filters in version 1.5 are capable of self-oscillation and can sound anywhere between clean to dirty depending on how hard they're driven. They are incredibly fast which means that no matter how much they are modulated it is practically impossible to make them "blow up". The previous filters are still available using the subtypes button which provide a broad sonic palette. A 4-pole band-pass filter has also been added, bringing the selection of types/subtypes up to 27.

Oscillator: FM2
This new oscillator uses 2->1 operator configuration and provides a quick way to generate harmonic sounds which are instantly useful in a musical context. It has a set of parameters designed to achieve this particular goal, providing an interesting alternative to FM3 which is the weapon of choice for 'scraping paint of walls'.

Oscillator: Window
This oscillator type combines a primary wavetable with a secondary "window" waveform which together provides a wealth of interesting formant-shifting and cross-modulation options.

Wide
This new setting is a serial filter-block configuration where everything is in stereo (oscillators, noise, filters).

Vocoder
A 20-band stereo-carrier vocoder has been added to the effect section.

Meta-controllers
The freely assignable controllers can now be named. They can also have their values edited directly in the GUI as well as automated by the hosting application.

More efficient
Through careful optimization in key elements of the DSP code using SSE/Altivec instructions the CPU-usage has been reduced by a significant amount. Memory usage has also been decreased.

Other changes:

Larger FM depth range

Tooltip fixes

Touch-automation fix

It wasn't previously possible to de-click the gate of the last step in the stepsequencer

Sinus waveshaper is called Sine

Level-meters of bypassed effects are cleared

No "useless divider" in the right-click menu of some sound categories anymore

Added check that the wavetables are loaded correctly in case of a broken installation

Updated manual

Added character parameter

Added more patches

Increased tidiness

Oscillator detuning settable as an absolute value (by toggle on the sliders context menu)

"Force integer" toggle removed. It has been replaced by holding down the ctrl modifier-key while dragging a slider.

Multi toggle switches no longer jump when outside their area

Audio input now works when surge is used as an AudioUnit
