Acid Rain Technologies has announced the launch of its Ziggurat “melodic playground” four-channel quantiser for Eurorack.
It’s designed to turn any combination of control voltage and gate signals into inspiring and unexpected melodies, providing a fresh way to explore harmonic relationships.
Explore different combinations of note masks, input signals, ranges and offsets, and then save all the settings into a patch for later recall.

Features
- Link channels by holding multiple channel buttons down together for 1 second
- Save + Load – 35 save slots (5 banks of 7) available to save and recall all module settings
- Slew – apply a slew to any note in your note mask. Adjust slew time from 0.1 sec to 5 sec
- Root – Apply a semitone offset to a channel output to change the musical key/root note
- Offset – Apply a semitone offset before quantization
- Range – adjust the channel output voltage range in octaves from -4V to +7V. Simply press the lower and then upper bound of the range you want (or the other way around)
- Chain – enter a series of notes in sequence (like an SH101 sequencer). A gate input with step through them in order, and an input voltage of 0-5V will move through the notes entered in either direction
- Mod – assign the mod CV input to load, slew, root, offset and range to dynamically modulate these channel parameters
Specifications
- 14hp
- 25mm deep
- 90mA on +12V, 10mA on -12V, 0mA on +5V
