Description

The HH-606 is a TR-606 HiHat clone in the Eurorack format, packaged in a small 2hp form factor to minimize used space on your rack. It supports additional functionality not available in the original TR-606 drum machine as well as features that make it more suited to the Eurorack format:

  • Accent (AC) CV / Gate (GT) Input: The accent input allows each trigger to have a different accent setting for more dynamic drum tracks. The HH-606 has two selectable accent modes: AC CV mode and AC GT mode.

    • AC CV Mode: AC CV mode allows the Accent setting to be modified by an external analog CV input. The AC trim setting acts as an offset for the AC CV input voltage.
    • AC GT Mode: AC GT mode allows the Accent effect to be gated (On/Off) rather than continuously variable, similar to the functionality of the original TR-606. The AC trim setting sets the accent amount for gated beats.
  • OH/CH Triggers The HH-606 can create both Open Hat (OH) and Closed Hat (CH) sounds.

  • Choke: Shorten the decay of the Open Hat sound at any point in the sequence.

  • Internal Gate to Trigger Conversion: No need for an external converter - the module responds to only the rising edge of a gate signal and creates a 1ms timed trigger pulse. This avoids double triggering on the falling edge of a longer gate signal.
