OveRview TABLe Of CONTeNTs OveRview The intellijel/Cylonix RAiNMAKeR eurorack-format module provides a high-quality (96KHz sampling rate with 32- bit internal processing) stereo rhythmic delay and stereo comb resonator effect. CONTeNTs A delay line in its most basic form takes in an audio signal and then sends it out again, but delayed in time, much sTeReO RHYTHM DeLAY seCTiON like your voice echoes in a large empty hall.
sTeReO RHYTHM DeLAY seCTiON sTeReO ResONANT COMB fiLTeR seCTiON The stereo rhythm delay line has 16 time-delayed taps, each with its own resonant 2nd-order multi-mode The stereo comb resonator section has 64 time-delayed taps which are summed together. This produces a deep state-variable filter and granular pitch shifter.
fRONT PANeL eLeMeNTs The functions of the various front panel elements are described in the following sections. A user of the Rainmaker module interacts with it through the module’s front panel. The elements comprising the global rhythm Delay Parameter editing user interface are one of six types: BUTTONS, OLED DISPLAY, LEDs, POTENTIOMETERS, ROTARY ENCODER, JACKS. eDiT/TAP# ●...

Turning the rotary encoder will change the DIV (clock division factor) value. When a clock signal is connected to the (left-hand) CLK input jack the beat time will follow the period of the clock signal, The per-tap parameters (MUTE, LEVEL,PAN,CUT, Q, TYPE, PITCH SHIFT, All taps multiplied by the DIV value.

When this display page is first entered, the Pitch L parameter is highlighted, and turning the rotary encoder will change both the Pitch L and Pitch R values. Pressing the button again will highlight the Pitch R parameter.
Per-Tap rhythm Delay Parameter editing Reverse Mode Operation The “TAP EDIT” buttons allow the setting and display of the per-tap parameters. The per-tap parameters are as reverse o follows: MUTe ● Mutes/un-mutes the selected tap. When muted, the output for that tap is removed from the rhythm delay output sum.

If the rotary encoder is pushed a second time then turning the rotary encoder will have a different behaviour, The TAP EDIT buttons have different functions depending on whether the module is in EDIT mode or TAP# mode, as indicated by the LEDs under the EDIT/TAP# button. When in TAP# mode, pressing one of the TAP EDIT buttons this time cycling between a set of preset ramp patterns.

Pressing the PATT+SLOPE button a second time will highlight the Slope parameter, and turning the rotary Comb Parameter editing encode will change the slope pattern to either Flat, Rising, Falling, or Rise/Fall. The slope patterns alter the relative amplitude or level of the tap signals before they are summed. At large comb sizes this is useful This section contains the main controls and parameter setting buttons for the comb effect.

moD Destination Description utility operations The selection of the rhythm delay’s groove type is controlled by the MOD Groove Amount signal. This is not an offset, but directly overrides the current setting. The red buttons on the upper right hand side of the module provide utility operations which determine the overall functioning of the module, as well as managing the storage of parameter values into presets.
