Block - Hi-Hats 1.0
Hi-Hat Generator and LFSR Noise Source
DESCRIPTION
Another Block in Michael Hetrick's "Euro Reakt" series! After a marathon of sequencing tools and trigger modifiers, here's an immediately useful sound source.
Takes in two triggers (HH GATE and OH GATE) and produces two "hi-hat" drum sounds (HH - Closed Hi-Hat, OH - Open Hi-Hat). To produce a hi-hat sound, two sound sources are used. The first is a Low-Frequency Shift Register. This produces a random 8-bit noise tone. The second is a stack of tuned square waves. These are mixed together and then multipled by a simple decay envelope.
Many outputs are provided, meaning that this can be used for much more than a drum source!
INPUTS
HH GATE - A positive signal on here will trigger the closed hi-hat sound.
OH GATE - A positive signal on here will trigger the open hi-hat sound.
OUTPUTS
OUT - Both drum sounds will appear here.
HH - Closed hi-hat only
OH - Open hi-hat only
NOISE - LFSR noise, post-filter
SQUARE - Stacked squares, post-filter
MIX - NOISE + SQUARE, post-crossfade.
CONTROLS
FREQ - Determines the frequency of the shift register, changing the overall timbre of the noise. Also determines the pitch of the stacked oscillators.
CUTOFF - Determines the cutoff of the high-pass filter on the noise source, and the band-pass filter on the stacked oscillators.
XFADE - Crossfade between the noise source and the stacked oscillators.
DECAY - Determines the decay time of the exponential decay envelope for the open hi-hat sound only. At minimal settings, this can be used to produce hits that are even shorter in length than the closed hi-hat.
OUT - Output level for the MIX output.
606/110 - Chooses the frequency spacing for the stacked oscillators.
x1/x2 - Chooses how loud the output can get.
