Ironhead:Spawn is a bundle of 13 individual polyphonic synths, built from mutated versions of the original Ironhead synthetic junk yard percussion kit instruments. They have grown, taken on lives of their own, and have been modified to be played across the keyboard like "normal" instruments. Their sound design abilities have expanded and they've been altered for a greater balance between percussive and melodic instruments, opening up a wide variety of sounds that are not possible with the original Ironhead, but while maintaining the unique Ironhead character and complimenting the original kit.

Kicks, snares, hats, cymbals, bells, rubbery basses, plucked strings, knocks, bonks, metallic smacks, tuned percussion, weird morphed noises... you can make entire pieces of music just using this bundle. The best way to think of the difference between Ironhead and Ironhead:Spawn is that Ironhead is a drum kit and Ironhead:Spawn is a whole band.


  • 13 plug-ins dedicated to unique percussive and melodic sounds.
  • Morphing for each instrument, controlled by LFO, mod wheel, or automation.
  • Minimalist vector based interface for fast, fun, easy sound adjustments.
  • Instrument randomizers.
  • Adjustable level of random tonal variations per-hit.
  • Dual delays in each synth.
  • Over 40 presets in each plug (over 540 presets in the bundle).

As an added bonus, just as with Ironhead, Ironhead:Spawn also comes with Tunguska... a morphing multi effect plug-in that includes a pitch shifting granulator, filter, envelop follower, distortion, downsampling, and delays.

Ironhead Spawn features numerous softsynths in a single product. The package focuses on percussive sounds, with an emphasis upon percussion that can be sequenced melodically. These synths are quite easy to use--even their names are intuitive things like "bash" and "ding". Each comes with an impressive array of pre-sets, which are logical extensions of the instruments using a range of parameters, rather than the "hey this is weird" detritus that sometimes affects softsynth pre-sets.

I've been playing with these synths since soon after I bought them, and I pronounce them "effective and easy". I use them in the simple [Bram Bos] Tunafish sequencer, in which they operate efficiently and generate a good sound. I found that when I apply my sequencer's flanges, gates and delays to these synths, I get very pleasing electronica sounds.

The GUI on these synthesizers is simple and clean. My only minor problem is that the synth GUI tends to "pop up" once in a blue moon after I have set it and minimized it, but I am not sure at all if this is a "synth issue" or a "user error" issue. Also, sometimes I have had to focus on making sure I am getting enough volume from the synthesizer called "ding".

I make ambient music most of the time, and these synths will be great for adding percussive elements in unorthodox ways to dark ambient pieces.
Today, though, I completed a more conventional electronica piece, which I reference for those who'd like to hear the synths in action (interfacing with Creative Commons samples--they're the percussion in the main melodic sections]:


This collection of synths is an excellent buy--well thought out, and targeted for the creator who'd like a dependable set of instruments without the calculations and complications of Buchla-like programming.
An artist could use this as a one-stop synth which, with a sequencer, would be virtually all one needed to easily create original music. That's because unlike some percussion synths, Ironhead: Spawn is intended to permit one not only to bash, crash, and thud, but also to do melodic thins like ding. It's a solid ping/bop experience.

Excellent free percussion synth, easy to use and some truly great sounding percussion with cool FX. Cannot fault this at all.
