Making Of

If you would like to geek out and see how I used a single slot and single original preset on the Nord Lead 4 to record the score in a single pass check out the "making of" the soundtrack film watch this.

Hands-On Review of Nord Lead 4 v1.30 OS Update

Photo Dec 28, 5 46 37 PM

On December 23rd, 2014, Nord released an OS update for the Lead 4 Synthesizer bringing it to version 1.30.

Download the update from here

I applied the update to my Nord Lead 4 yesterday and got some hands-on time using the new OS. In this article I'll offer some first impressions followed by the comprehensive list from Nord on what's new with annotated notes.

Innovator's Paradox

Before I talk about the update, I do want to mention that I was really hoping the Lead 4 would inherit some features from its newer little sibling the Nord Lead A1.

Izotope Iris 2 Hands-On Review, Tips, Early Sound Design Experiment Videos, and First Impressions


I just started experimenting with iZotope’s Iris 2. Wow! Iris 2 wins the award for most improved virtual instrument for me in 2014!

While Iris 1 focused on interesting ways to manipulate samples using photoshop-like editing to do spectral filtering along the timeline, it was lacking on the automation and sound shaping side for me. Things have certainly changed for the better in Iris 2!

In this article I’ll offer a hands-on review of the new features, offer some tips, show you some early sound design experiment videos as well as offer first impressions on Iris2.

There are plenty of Iris 1 reviews and videos out there so I’m not going to cover that ground. I also won’t cover the Spectogram editor either. I do offer some links to video tutorials at this bottom or the article if you want to see these features in action.

In a nutshell, Iris is a sample-based synthesizer with four audio pool layers that can contain your own samples or samples from the factory library. The spectrogram display allows you to manipulate edit the audio spectrum across the timeline. Iris 1 was released in April of 2012. Version 2 was released in November of 2014.


You can play tune and play samples back like a classic sampler in various modes that allow you to play samples forward, revers, looped, and triggering one-shots. Radius-RT mode allows for real-time pitch shifting. In other words, in Radius-RT mode, playing the sample higher up the keyboard changes the samples pitch but not the speed as it would in the other modes.


Modulation and Automation with Visual Feedback

Iris 2 now has 5 LFOs, 5 ADSRs, 8 Macro knob mappings, MIDI mappings (mod wheel, aftertouch …). There are over 100 Modulatable parameters now!

The new modulation system is killer with simple drag-n-drop style mapping (you can also use right-click). Once you drop you can scale the level of modulation on the target circle. A ring will also appear on the target allowing you to further manipulate depth. You get visual feedback in real-time as parameters are modulated.


In the illustration above I mapped LFO2 and Macro Knob 1 to modulate LFO1s rate.  You can also modulate the shape of an LFO.

Tip: Envelope 5 is mapped to master gain by default making it the AMP ADSR. You can of course repurpose it, but go to ENV to make tweaks on factory presets.



In addition to 4 master effects that were in Iris 1, there are now 4 insert effects per sample pool. All of the parameters can be modulate and automated. iZotope did a great job implementing this so there are little or no artifacts.

Must Read for Waldorf Blofeld Synthesizer Owners: New 1.23 Firmware for Blofeld + New Spectre App + Secret Sauce for Getting Spectre Sample Transfer to Work After Upgrading

Photo Dec 12, 5 15 45 PM

Update: This is a long article and I've rendered it as pdf and Open XML paper so you can read this offline and print it.

Blofeld users rejoice! Waldorf has released a free firmware update for the Waldorf Blofeld synthesizer. It's kind of a life changing update in that it allows you to transfer only new samples from a new Program in a Program List rather than transferring all samples in a program list - hooray!

Most seasoned Blofeld users seem to be having trouble getting the new features working - boooo!

I'm a long time Blofeld/Spectre user but I not things to work first try. I did figure it out after about 3 hours of research and trial and error and wanted to pass along my findings to save you time. Yaaay!

Details and secret sauce of how to get new features working is below.

Dear Blofeld Friends,

There is a new Blofeld Firmware Update, V 1.23.
