Is this behaviour intended?
-
I made a simple delay modulation, and what I hear ain't a triangle thing... Kind of jumping instead
Playing with the skew factor of the DelayTime radically changes the behaviour, but I can't find a value that respects the triangle.
Try a skew of 0.5, 1, 2 and hear the radical change
Although this might be the essence of what a modulated delay is, I don't know...HiseSnippet 1577.3oc2Y0rbaaCDFTxTIxNoSRqSaOpC8fyLodHcRyOSOXYaYkpoQ1ZrbcxMWDRHKTQBvRBYa0N8Tuza8bt0WidKu.clNSeAxiPdCZWPPJBJonHoT6NMZFaKr3m8C6teKV.2Jj6Phh3gHixGNHffLtlY6ALQ2c5hoLTiZRA9b29dXAkyPaOH.GEQbQFFEerbDFkWBE+40atM1CybHYhPni3TGxSn9TQlzVU+ZpmWcrK4Ppu1nuW0FNb1NbOde.MEMsPAXmd3SH6gkCqfIxnzttTAOrs.KHQHik1l6NncW9YL03OhFQetGQ1vF0FVHk35bOWIhkRQ6zk541JcWGgPFlsxrAEU1fUMaRcoCkmYKtQbGUxlgt8vnPd3ULG7r0gmkF7l.jLzfzRJHcSy1Ngz.QVOR7rhYClfD1AClccnnFKx3kl6vgAvDq6i6QpGBMFNg0tuk0cp.+51eYm9LGo6sBmsGWP1ms1sW9GWt7x+zxUFsqNclXeR0Dx87HgSraomNbZSbMVe+mSBuSkSwd8ICGHr8yaSMey1TcWtiZWqMPNqAiJ1OfvdSABnDSE7suoQMr.KcDIxfwEPBETIDLpQNEhpUtkxl0HQ8D7.HtdLeFDsnXN4Cgj7llSlRIcNrHpXfNuZz3pkls3poG1Oqv8llsnBmtSFuEl.dAq1EMdSXoW2b2NcHNhLvtjY8mMUJ4bCkYkdtbB8DzuJmopYk5OydhDyewLiDDDRBvgjC4s7vCVKB6G3QN.v6cp7bOtSu1zefLNyIPAgskiXMmtXFi3EsHDrRybRK6olzBc.uufxNoIVDROGXp602uMjJ2grSB5.YFEj7LUaKYaY7RaByMtweCeR5zV11HoS6zN0nn6QDmwC6E6NR9N3LT19nXi7wcN2FskmG+rc39AzjnWvGDKqE2aPPWNi5HEoFQJR2xm2GTRBbMJrG2EL.l0wNfgZPKrnqjWHyw.Adjv0czNqTS259c4RjdzlZWCpzWtUhOXqnVBFU7krEvpJnV0FQGI60A6gNR5+jbOjbMU6eE9TCsC87GdbbfCJGf+XM.qMlKVPVbHHKnAxUjUTDazryiwU0vX5PtzLiEyYF4QNPUJxbgnw76gj005dQwmrKfoed5QM0nQAPBfs6CI0ToYxIQtIXtjyS4B6BzYWHKU7zS4GsvgPwRB07KMrE78lTVxVNKQcS74iH6FUaKHAxLN5G.0tG4LkQPWpzNURdjAAM5JWEM+pFMpp+sW7heebUW8m8+iMUAQ0CIeeeByYPN8C+7pMeK5+0aNt9slys90h0ekCjoUPis9KfA.T1bZ6eLjx9BS0Pp22npuhYqt3nw86nKAcWJt9oIrsUz2RxwT1LhdxFPFj7b2OvzG965o8M6D2z5ALJXTHGENGey3xvvqVfwM7ZIuJYFPvij8eEUZq3NliDVKka2lUD3g3vSHhnjJjYDG0YqwI4a.K7UM+NWBj5Jy.IktBTrLHL9ZeWzY+x2Py5LDZ4rOWGjFErdRWygEZJwCEl63gp+Z0YJd3a+nZ+UR7f5x0isL5DwqLawh68V08plVqeWKaq6ZYY8nG8v68nGXYmbMzLGaxpJKRbq9BNv3TLmo3c1ly64iiKl6c9pW2R04JlOEeJI9kLhQ3sha2gG5W4wDn7B4I21S40L9yY80LBl4WyXeGA.gCCwrn.dDwVake4H8sgtVqQD8Y4FdhnbiRt8pCaOswc0poB2PWXKLK2hAsysRMkUum17UatKCC0+2l.6F28yp5QeA56EQdJ0Uz0VehYh2PW7WgCcA+hStaLVblul1b7vNktndXmK0Kf+t+dA+67NTkSwXapLw8trSId.yLFieHPE6f66IRklmZ0jy3o20Jyoe.Atn3ImPxeH2j1PaIDX3pJCkrZ0CHdDYAHCE8YUeBbqAbXb4nKlsvdteStI5u9TSEbqHyGT48i24o368uyy6FCERY9+GO8mXBow2nRr6tx+896KimM5xPG9XmP9wNpWaSlv3pwRf8MK9+eQYylx1UrQmppPxDplxB4CG6briiLl9yA6yjmyFKvbt6BLm6s.y4KVf4b+EXNOXAlyCm5bjm3mThpL9GDzZW08ILTE8DSEP+CTXVP.A

Further testings show that apparently, what is important is the change in rate. A triangle has a constant slope, but on the contrary, a sine continuously changes its slope.
Try with a skew factor of 1, a sine gives a sine result, but a triangle makes the delay to change only when the slope changes (so only at -1 and 1) making a "square like" result -
@ustk If you're modulating the delay, you're in fact modulating the derivative of the frequency so a triangle modulation of the delay time will yield a square wave frequency modulation.

@christoph-hart Me, entering the DSP world... :)

@ustk I'm preaching like I'm the god of DSP, but I literally found this out 2 weeks ago when I was trying to modulate the delay with a triangle and wondered why the frequency jumps around, so I guess I have a headstart of two weeks over you...

@christoph-hart Was thinking you were a genius mathematician, but I've just been fooled...
I'm working on FFT, filters, FDNs, and other pleasures, and I understand now why 10 years are the minimum delay for getting a hand in dirty DSP thingies
