Hi List!
I'd like to reproduce the percussive sound that can be heard used as some
sort of "snare" in this video <https://www.youtube.com/watch?v=KQcI7oKE1pc>,
you know the "marble on a glass table" thingie?
Hi Philip,
yes you can do that subtractively. I'd suggest this:
white noise as sound source
and a lowpass filter (combined with a constant frequency highpass or try
a bandpass. I believe specialised bandpass filters are common in
analogue drum machines.
Use an ADSR envelope on the source volume with a longish attack
Use an LFO (sawtooth/ramp down) on the filter frequency
Or use a short ADSR on both filter and volume and then apply a delay.
There are two distances between the "bounces" in this video, that means
you should have a way to change the LFO or delay length (perhaps mapped
to MIDI note).
If you synth has it you can also use a loopen envelope to achieve the
"bouncing" effect. That is probably better, since you can better adjust
the characteristic of the "bounce".
I'm not familiar with purely GUI based synths, but I'm sure Yoshimi can
achieve that. A well-featured virtual analogue can also do it. Amsynth
or AMS spring to mind as well. I seem to recall that whysynth was
well-regarded. Other
options also include PureData and Csound and possibly Faust.
The reverb in this recording sounds a bit like a spring reverb, which
you can find anywhere, as LADSPA, LV2 or - I'm sure - native VST or
maybe as a standalone tool. Jconvolver also includes a spring reverb
impuse response. You could use that with other IR plugins. You can
search your distros package repository for IR or impulse response or
convolution. If you have a lot of things installed, you can also try
your favourite DAW and browse through the list of available effects.
