Voltage Controlled Wavetable Device
The Malekko Richter series in Eurorack modular format offer the same great sound, ergonomics, musicality, and quality that made the Wiard 300 series legendary, at a fraction of the cost and size.
The Malekko/Richter Megawave is a selectable wavetable device featuring many of the available preset Wiard Miniwave ROM waveforms. Each of the ten ROM selections contains 256 waveforms. Not an oscillator, the Megawave can be used as an audio wave shaper, complex LFO function generator, stage quantizer, random function generator, non-linear waveform distortion unit, etc.
WAVE, BANK, and ROM selection are all voltage controllable and each CV input has fine control.
MEGAWAVE CONTROLS OVERVIEW
The Megawave features 2,560 waveforms arranged as 10 ROMs of 16 Banks per ROM, with 16 Waves per Bank, providing many of the available preset Wiard Miniwave ROM waveforms. ROMs, Banks and Waves can all be selected manually or scanned with control voltage (e.g., with a sequencer, envelope, joystick or random voltage generator), and each CV input has a fine control EXT pot.
INPUT/OUTPUT RANGE SELECTOR SWITCH:
The Megawave functions in two different modes (0-10v or +/-5v) set by the “Range” selector switch. Depress for +/-5v mode.
In the control voltage range, it can act as a control voltage quantizer (into 16 pre-programed music scales) or as a virtually unlimited source of smooth and stepped control voltages.
In 0-10 volt mode, the input accepts 0-10 volts and Wave selection follows the sum of the manual and external wave select voltages, without regard to the input signal. The module output is between 0 and 10 volts depending on the number stored at the ROM address pointed to by the input voltage.
In the audio range the module can function as a waveform wavetable playback device or as a nonlinear distorter to add harmonics to a sine wave. It can also process any audio signal pre-amplified to the +/- 5 volt range.
In +/- 5 volt mode, the input accepts +/- 5 volts and Wave selection is only updated at the zero crossings of the input waveform. If the input is a raising sawtooth and the internal waveforms are developed with that in mind, the wave will only progress at the zero crossing points and remove “clicking” from the wavetable sweep. The module output is between -5 and +5 volts depending on the number stored at the ROM address pointed to by the input voltage.
INPUT WAVE TYPE SELECTOR SWITCH:
The Input wave type selector makes it possible to pair the Megawave with oscillators which produce ascending or descending sawtooths (such as that produced by the Richter Oscillator).
CV IN FOR WAVE, BANK, ROM SELECTION:
The input voltage ranges for the external Wave, Bank and ROM select are always 0-10 volts. Fine tune your input with the EXT control knobs.
INPUT OFFSET ADJUSTMENT:
In +/-5v mode, the Input Offset is designed to adjust for optimal audio input to achieve minimal distortion based on the VCO used.
INPUT GAIN ADJUSTMENT:
In 0-10v mode, the Input Gain adjustment ensures accurate quantizer functions tracking. Also acts as an input gain.
The Megawave wavetable device is 16hp, 35mm deep, and consumes around 90mA power.
