Crum Drum is a 4-voice drum machine with built in randomisation and probability based sequencing designed by NYSTRÖM
Rhythms can be created and manipulated using the internal random sequencer or externally via MIDI USB. Press the beat button to generate new rhythms, adjust the probability to create continuous variations, and increase the randomness to modulate the sound of your beats! Generated sequences can also be sent out via MIDI USB and Crum Drum can also sync via analog clock in and out.
The four voices of Crum Drum are Kick, Snare, HiHat and Bass (FM). There are 8 parameters knobs to sculpt the character of each voice allowing for wide variety of tones. It’s easy to create varied and organic sequences by adding modulation via the Probability and Randomness controls. Probability sets the chance that the selected voice will play per step of the sequence, while randomness increases the parameter modulation for each voice. The higher the randomness, the more each instrument parameter is modulated per step. Some of the instrument parameter controls have different behaviours depending on which voice is selected, so make sure to check the user manual for full details.
