IRIS Collection Vol 1 is currently on sale for $39.99 which includes all 5 IRIS Releases.
Gratis IR as the name suggests is a completely free collection of Pads for Izotope IRIS which is equal to half of one othe paid collections. Although some samples are used from the other IRIS releases, the actual IRIS instruments are all unique to Gratis IR.
The instruments were constructed using 1-3 Samples and take full advantage of the Spectral Features of IRIS, and most have Aftertouch assigned to the Filter Cutoff. The intention was to provide musically useful Pads full of texture and movement. All 100 WAVs that form the Gratis Sample collection are also available to explore when creating your own sounds.
