FDNCymbal

FDNCymbal is a cymbal sound synthesizer. It can also be used as an effect. Unlike the name, most of metallic texture comes from Schroeder allpass section rather than FDN (feedback delay network). FDN section makes nice impact sound when FDN.Time is short. Tremolo is added to simulate wobbling of cymbal.

The package includes following builds:

macOS build isn’t tested because I don’t have Mac. If you found a bug, please file a issue to GitHub repository or send email to ryukau@gmail.com.

Linux build is built on Ubuntu 18.0.4 and tested on Bitwig 3.0.3 and Reaper 5.983. Both seems to have problem to display GUI, therefore GUI is currently disabled for Linux build.

Installation

Place FDNCymbal.vst3 directory to:

DAW may provides additional VST3 directory. For more information, please refer to the manual of the DAW.

Linux Specific

On Ubuntu 18.0.4, those packages are required.

sudo apt install libxcb-cursor0  libxkbcommon-x11-0

If DAW doesn’t recognize the plugin, take a look at Package Requirements section of the link below and make sure all the VST3 related package is installed.

REAPER 5.983 on Linux may not recognize SevenDelay. A workaround is to delete a file ~/.config/REAPER/reaper-vstplugins64.ini and restart REAPER.

Controls

Knob and slider can do:

Caution

When FDN.Feedback is non zero, it may possibly blow up. If that happens, turn FDN.Feedback to leftmost.

When HP Cutoff is moving fast, it may output massive DC. To avoid this, use Shift + Mouse Left Drag or turn up Smooth.

Parameters

Gain

Output gain.

Smooth

Time in seconds to move the value of parameters from previous one to changed one. Below is a list of parameter that is affected by Smooth.

Stick

When Stick is on, each note on triggers stick oscillator. Noise density and pitch of tone are related to the pitch of note.

Decay

Decay time of stick oscillator.

ToneMix

Gain of tone of stick oscillator.

Random

Seed

Value of random seed.

Retrigger.Time

When not checked, internal delay time controlled by following 3 parameters will be changed for each note on.

Retrigger.Stick

When not checked, stick oscillator output varies for each note.

Retrigger.Tremolo

When not checked, tremolo parameters will be changed for each note on.

FDN

When turned on, the signal go through FDN section.

Time

FDN delay time. Internal delay time will be randomized with respect to this value.

Feedback

FDN section feedback. Beware that if this value is non zero, it’s possible to blow up.

CascadeMix

Controls mixing of Cascaded FDN.

Allpass

Mix

Mixing ratio of Schroeder allpass section.

Stage 1 and Stage 2

Stage 1 is serially connected 8 Schroeder allpass. On stage 2, there are 4 Schroeder allpass section connected in parallel. For each section has serially connected 8 Schroeder allpass.

Time

Max delay time of Schroeder allpass section. Internally, delay time will be randomized.

Feedback

Feedback of Schroeder allpass section.

HP Cutoff

Cutoff frequency of high-pass filter to the output of Schroeder allpass section.

Tanh

When checked, stage 1 feedback go through tanh saturator.

Tremolo

Mix

Mixing ratio of tremolo effect.

Depth

Maximum change of amplitude with tremolo.

Frequency

Tremolo LFO frequency.

DelayTime

Maximum delay time. Delay time is modulated by LFO. This delay simulates doppler effect.

Random (Tremolo)

Depth

Amount of randomization to Tremolo.Depth for each note on.

Freq

Amount of randomization to Tremolo.Frequency for each note on.

Time

Amount of randomization to Tremolo.DelayTime for each note on.
