ULT-SOUND is now selling its compact DS-1 drum synthesiser designed for Eurorack modular systems.
A streamlined version of the flagship DS-4M, it has the same analog circuitry and design but in a space-efficient form.

The panel includes:
- Sense Level knob for adjusting how the module responds to incoming gate signals.
- VCO with three primary waveforms (square, sine and triangle), with fine-tuning available.
- Envelope with sustain and attack pots
- LFO for adding vibrato, selecting square or triangle waveform and using the frequency control slider to determine vibrato speed.
