iZotope Iris 2

[Sampleconstruct]

After some experimenting, I am able to get the lfo/envelopes working per sample the way I expected them to. My oversight(s) was the invert button combined with a negative modulation range. My focus was on the gain parameter and release of the envelope. I am now able to get samples that are independently adjustable and from envelope 5. I was using it wrong. More study for me.

Oh I see, that was a totally different issue then. If you set Gain to -∞ and then apply envelopes you don't need the invert button.

My focus was resolving my issue of the adjustments of the envelopes applied to gain would seemly override the envelopes of other samples, causing the release to be affected the same across all samples. I would get all samples releasing the same. So setting as I explain in my last post seems to work in this situation. Gain is reduced where I want, but voice count seems to remain. More experimenting is needed to be certain of that. I have to admit, nonlinear modulation of modulators then combine that with daw automation is quite a memorizing thing. Quite a leap from the hardware I'm use to.

Iris 2 has its critics, maybe rightfly so, especially in your case, but I would really like to hear and share with what others have done.

BTW, your patches are amazing Sampleconstruct.

@Sampleconstruct. Just having a play with the demo at the mo, and I'm able to modulate the volumes with multiple mods as expected. i've got an envelope in slot 1 of an oscillators volume, an LFO in slot 2 and a macro in slot 3. All mods a multiplied. Both the volume and LFO modulation rise and fall according to the envelope shape. The macro controls the depth of the LFO modulation.
Is that what you're saying isn't working? Not sure if I'm mistaken or not with what you're trying to achieve.

EDIT: Obviously there's a whole load of different permutations when applying modulations, most of which, if not all, you have probably done, but everything seems to work here so far.

No, apply the modulators all to one oscillator, that's where Iris 2 fails. I often make patches where I assign the volume of an Osc to a Macro, and a synced LFO to the volume of the same Osc, when I set the envelope controlling that Osc to a longer release, the LFO will add it's values during the release phase, so the release sounds totally wrong/un-natural, and the Macro will also add it's value to the overall level - meaning that the controllers work against the amplitude envelope. So when you want to use modulators for the volume of an Osc, just use the master envelope (5) and assign it to the main output, that means that all oscs will have the same envelope but at least one can use the controllers.

All of this has been acknowledged by the iZotope “product manager“ Brad, who used to participate in this thread and with whom I communicated with via E-mail for many weeks until he disappeared.

I am applying all mods to one oscillator. I've just tried what you described and it works.

The patch has the master envelope in mod slot 1.
Then in a single osc I have assigned a macro to mod slot 1, a separate envelope to slot 2 and a LFO to slot 3. Both mod combines are set to multiply. Also both the main vol and osc vol are set to minimum.

Now I can control the osc vol with the macro whilst the envelope shapes it, and the LFO follows the envelope in a natural way i.e it fades in and out according to the envelope.

EDIT: I see a problem with this setup now though, which is that you can't set a minimum vol (other than silence) in the LFO's range without turning up the osc vol, which then mess's up the macro, as you can still hear the osc when the macro is at minimum.

[quote="Sampleconstruct"]I programmed so many workarounds on Iris 2, believe me, combining Macros/LFOs and envelopes all assigned to the volume of an oscillator is not working in Iris 2, no matter what the manual says. In Iris 1 this is not an issue at all, but the whole architecture changed to the worse in Iris 2, that's just a fact not an opinion.[/quote]

I agree that the way the modulators interact in Iris 2 are a bit screwy, but there’s usually a way to do what you want it to do. In your example, you can always use an envelope generator to modulate the depth of the LFO so that it is decreasing in amplitude as the sound decays. I find that there’s usually something about any sound generating/modifying device/software that doesn’t work the way I want it to; that includes most acoustic instruments. The bottom line is: if you can get something useful out of it, that’s all that matters. For me, besides its spectral shaping abilities, I purchased Iris 2 mainly for its ability to play multiple oscillators in Radius RT mode. Different strokes for different folks, eh?

After all that nerdy technical talk I just had to make a fresh Iris 2 patch, so here it is, using a guitar soundscape I played/made last night:

As always, beautiful and interesting sounds you create.

Back to the nerdy shit

For what it's worth, I've found a solution. In the oscillator, if I change the combine mode of mod 2-3 to Add, instead of Mult. Now in the LFO, turn the depth knob to minimum, and then assign the same macro and envelope as used in the oscillator, to mods 1 and 2, and multiply. Now you can balance all the mod depths to taste.

Right... back to deciding whether to upgrade or not

No, that's not a solution, I want individual controls for either volume of the osc and the modulation, your workaround will always add modulation when the osc becomes audible. I wouldn't have bothered if Iris 2 would have been version 1, but trying to convert all these Iris 1 patches which use this kind of setup to the new architecture in v2 is not so much fun.

Wouldn't it be fairer to say that it's a solution for Satch1 but not a solution for you? This stuff isn't so absolute; it's not right or wrong. If it works for what he is trying to achieve, it works for him. As a device, a Mellotron sucks, but a lot of great music (in my opinion) has been made with them.

[Sampleconstruct]

LOL, I give an izotope about being right or wrong and what does the Mellotron have to do with all of this? Beethoven was deaf in the end and most birds can't swim.
