Hi All,

I thought I'd share a synthetic harp patch that's loosely
physically-inspired.  There's subtractive synthesis used for a string
pluck sound and a reson bank for a (perhaps overly!) resonant body:

https://ide.csound.com/editor/G6ksxg6mOp0T9qB1HCd6

The project above has a melodic pattern generating for testing purposes.

Code body for instrument is as follows:

instr Harp

  ;; STRING SOUND
  asig = vco2(.5, p4, 2, .45)
  asig += vco2(.25, p4 * 2, 2, linseg(.5, .1, .05, p3, .05))
  asig += vco2(.25, p4 * 0.997934234, 12)

  asig = zdf_ladder(asig, cpsoct(linseg:a(13.4, .1, 10, 1, 5, p3, 4)), 0.5)

  ;; BODY SOUND
  a1 = reson(asig, 800, 160) * 0.05
  a2 = reson(asig, 2000, 400) * 0.05
  a3 = reson(asig, 3000, 650) * 0.05

  asig += a1 + a2 + a3

  asig = dcblock2(asig)
  asig *= linen:a(.15 * p5, .001, p3, .01)

  pan_verb_mix(asig, 0.5, 0.1)
endin

(replace pan_verb_mix without out(asig,asig) if testing locally)

Cheers!
Steven

Very cool sounds!  And your reson banks are fascinating!  Easy way to
add a formant aura around a sound?

Thanks all!

Jeff: I was thinking along the lines of formants when I started coding
this instrument. I think I don't spend enough time designing sounds
with reson/mode and will probably continue to practice and exploring
with them.

Victor: Thanks!  I think once we have collections implemented in the
Web-IDE I'll be organizing a number of the items I posted into various
collections. Just need to find some time. :)

asig += vco2(.25, p4 * 2, 2, linseg(.5, .1, .05, p3, .05))
should do the job.

here an old one (see image) - the juno 60. had the possibily to modulate the pwm (kpw) parameter by using the envelope.

Hi Steven,

I have a question, too!  You seem to have created the pluck sound by using
the zdf_ladder to sweep the filter frequency against the fixed-frequency
source tones.  I initially assumed that the linen envelope at the end was
doing it, but I removed that envelope (with a suitable volume adjustment)
and I hear little difference!

Is this a common technique, or is it original here?

Thanks,
	-- Pete --

Hi Dave,

Might be odd to say but I kind of just came up with them intuitively.
I had my students use the formant table from manual for the soprano
'a' for an exercise so I had those kinds of relationships of center
frequencies in mind, but I wasn't consulting any charts or analyses
when I chose these frequencies. The bandwidths I approached as a wide
proportion of the center frequency and then just experimented.  I
should mention I adjusted the attenuation in the version online since
my original post here
(https://ide.csound.com/editor/G6ksxg6mOp0T9qB1HCd6) to:

  a1 = reson(asig, 800, 160) * 0.025
  a2 = reson(asig, 2000, 400) * 0.04
  a3 = reson(asig, 3000, 650) * 0.03

to balance the resonance a bit.

Cheers!
Steven

Hi Pete,

(For some reason your message went into my spam folder so I didn't see
the message until now. Hopefully will be fixed now!)

I don't think there's anything original about the filtering for a
plucked string? I think the effect makes sense and karplus-strong
string plucks have a similar spectral evolution in attenuating the
higher frequencies faster than the lower ones.   I use linen alot for
declicking and sometimes to soften attacks if most of the sound
shaping is done through the filter cutoff. (I just tried with .03 for
linen rise time and got a sort of wineglass rub sound, fun!)

Cheers!
Steven
