The HATS909 is Roland's TR-909 analog Closed and Open Hi-Hats sound generator
adapted for modular synthesizer use. The front panel contains all of the controls
found on the original TR-909 drum machine, allowing you full control over the
sound’s volume levels to mix with other drums and accent levels. In addition to
those original controls we have also added new controls, further enhancing this
legendary sound generator.
Let’s get started.
To start using the HATS909, just plug a gate signal into either the OH GATE or
the CH GATE input, plug the HATS OUT to your sound system, set the LEVEL half
way, set the TUNE knob to about half way, set the SOURCE switch to 909, and set
ACCENT to halfway.
OH vs CH and SOURCE switch.
The HATS909 is a low-fi sample based generator that is capable of producing
only one sound at a time; the default is the OH sound which overrides the CH. If
a gate signal appears at both inputs simultaneously, the OH will sound. Each of
those sounds have a DECAY control knob to set the length of the analog envelope
applied to that sample sound. Setting the SOURCE switch to RAW bypasses the
envelope and filtering of the sound sample, giving you the raw sample with no
processing. RAW mode is great for using your own filters, VCA, and envelope to
process the raw sample sound. When set to 909, the sampled sound pass through
the original analog filters and VCA of the 909 machine.
