this is the BUG list from Sampleconstruct! any more additions?*The Sample&Hold (random) LFO is still broken in version 2.01, in most cases it decides not to modulate, sometimes it modulates, so it’s behavior is very erratic. Also the speed of the random LFO can currently not be modulated with any controller. So all patches using a random LFO are affected by that. iZotope is still working on a fix for this issue (they said in March 2015).
*When you assign the modulation wheel to the main output gain using negative values, e.g. something like -20% to compensate for the gain boost introduced by the distortion FX (also assigned to the wheel), the next time you open the preset the wheel will totally mute the output when fully engaged, as the master output knob at the top of the UI can't be assigned to any controller anymore, the only workaround is to individually assign negative values to the individual outputs of each oscillator.
*Trying to modulate Chorus depth (not mix) with a Macro doesn't work, the knob modulation indicator is actually moving when tuning the Macro but the sound doesn't change.
*Since Iris 2 the Send-levels to the FX modules are routed pre-envelope, so when a patch is using the FX-Send-mode, a sound will reach the FX section although it’s sustain level might be turned to zero. They are thinking of adding a pre/post-switch to fix this issue, the workaround is, to also assign the amplitude envelope of an oscillator the the respective send level.
*The feature to change LFO waveforms via Macros has been removed in Iris 2
*As the minimum/maximum modulation amount was removed in Iris 2, some modulation values can not be assigned accurately anymore, like e.g. delay times, cutoff levels etc, so some modulation levels might slightly differ in the converted Iris 2 patches.
*The new architecture of Iris 2 renders some former assignments useless/impossible, so I used many workarounds in the Iris 2 patches, sometimes I also added a few modulations here and there, taking advantage of the new modulation system. But the new patches sound just as good
*The zipper noises in Iris 2 when moving/automating Macros and other controllers like the Modwheel have increased significantly in comparison with version 1, if you move them slow enough, you will be able to avoid those artifacts.
*CPU usage has significantly increased in Iris 2.
*The master output knob at the top of the GUI can't be modulated anymore.
*Limiter amount can't be modulated anymore.
*Modulating delay time with an LFO does not produce usable results.
One more omission is:
*Modulation amount via velocity can not be modulated in Iris 2, so it’s either on or off.
In version 1 we have minimum and maximum modulation levels which can easily be assigned by right clicking on any parameter which can be modulated, this is missing in version 2 so assigning the max level has to be done by guessing. I enter the values numerically in Iris 2 if I need more exact levels, the graphic representation of min/max mod levels in Iris 2 is...problematic to say the least.
