each band at the end of the chain. There is also an overall scaling control for each of frequency, resonance and low-pass filter controls. Additionally, any of these controls can be either MIDI controlled or controlled by the internal “Agitation� settings. The sound of the filters is very clean, and they ring nicely at the higher resonance settings, although there is always a bit of the original sound that comes through the combs. Where this module excels is in adding coloration to a sound, usually subtly, but at higher settings quite radically.
original sound is almost totally replaced by the ringing of the filters. In fact, one can produce successions of resonances (chords) in which only the timbre and balance of the sound is affected by the original sound. In terms of overall sound, the filter can vary between only lightly colouring the original sound to metallic sewer-pipe like ringing to the aforementioned hanging chords with
The last of the filters in the Classic series is Reson, which takes a unique approach to Figure controlling a bank of filters with a minimum of controls. The Tool can have between 2 and 64 filters, which are spread over a range set by the low and high controls, which are controlled by the ball. The filters can be evenly spread over the whole range, or they can be clustered at either end of the range, controlled by the distribution curve control. The Random Factor control can then further transpose the filters by a certain amount, and the S&H rate sets how fast the filters change their Random Factor frequency. The S&H rate can be set from very slow (about 1 change a minute) to well into the sub-audio range (about 4-5 changes per second). The Resonance control can be set from 0, which is no resonance, to 1.0 which is all resonance, and the
no hint of the original. Again, everything can be MIDI controlled or affected by the new Agitation feature, making this an incredibly powerful resource for sound shaping. Reson was one of the most powerful modules in the original GRM Tools. Now, it’s even better.
