Bring your umbrella and get ready for a deluge with the intellijel Rainmaker, an advanced 16-Tap stereo spectral rhythm delay and comb resonator in Eurorack format. Developed in collaboration with Cylonix, the Rainmaker allows individual control of any or all 16 taps-set timing, level, pan, filter type, cutoff and Q on each tap. The Comb Delay opens up further possibilities for complex comb filtering, along with resonator or reverb effects.

The Rainmaker module has extensive voltage control capabilities. Direct voltage control is available for the delay feedback level and tone, the global pitch shift for all delay taps, the comb resonator size, and comb feedback level. There are two assignable modulation inputs, which can be assigned to different parameters in each preset. A trigger input with assignable functionality can trigger built-in types of noise bursts, freeze the delay buffer, reverse the delay, randomize parameters, mute taps, and much more. The module includes a ribbon power cable.

• 16-tap Rhythm Delay section with comprehensive control of each tap
• Comb Delay section with up to 64 taps controlled by preset patterns, slopes, and filters.
• Delay CLK IN, Comb CLK IN, CLK OUT and clock dividers allow for synchronization with other elements in your patches.
• 96 kHz, 24-bit (32-bit internal) signal processing
• Most parameters are controllable by external control voltages, either directly or through the two auxiliary modulation inputs (MOD A, MOD B)
• Audio-rate randomization of all parameters, or selectable subsets of parameters
• 128 Preset slots with online preset librarian via Laser Mammoth and USB connectivity

• Each of the 16 taps has its own set of audio processors:
• 2nd order resonant multimode filter (LP, BP, HP) with adjustable cutoff frequency and resonance
• Level and Balance setting, with quick-mute capability
• +/-1 octave granular pitch shifter. 1, 2, or 4 grains with adjustable grain size
• Delay line feedback can be taken from any of the 16 taps (pre-filter) or from the sum of the 16 taps (post-filter)
• Delay line feedback has its own granular pitch shifter and 1st-order tone filter
• Global delay time can be set either by manual entry with the encoder, by an external clock with adjustable clock divider, or by tap tempo button
• Individual tap delays are set according to one of 16 preset grooves
• Global delay time modulation by an LFO with 8 selectable waveforms
• Delay times range from 0.1 millisecond to 20 seconds
• Delay buffer freeze and reverse
• Taps can be piled on top of each other to give complex filtering and chord effects
• Global pitch-shift control transposes the delay line output by +/-1 octave

• Comb can have between 1 and 64 taps allowing for complex resonances
• Three different nonlinear comb feedback structures for spectral shaping
• Comb is pingable to give physically modeled guitar, sitar, and clarinet types of sounds
• 16 different comb tap spacing patterns
• Global comb time can be set either by manual entry with the encoder, or by an external clock (with adjustable clock divider), or by a 1V/oct control voltage
• Global comb time modulation by an LFO with 8 selectable waveforms
• Comb times range from 0.1 millisecond to 20 seconds

There are 128 nonvolatile memory slots into which you can store sets of parameter values. These can be recalled at any time by pressing the LOAD button, turning the rotary encoder to select the desired memory slot, and then pressing the rotary encoder to execute the loading operation. Although these memory slots can be overwritten by the user, they come prefilled from the factory with interesting preset configurations. These factory presets are listed and briefly described below. Presets 82 to 128 were created by Richard Devine.
