I have finally been able to get something in Logic which may work as a "sul ponticello". My attempts to buy VSL samples have come to naught after a year since they seem unable to answer my question there. (I checked out the articulations and can't find any except that a YouTube video shows one; not sure in which collection.) http://www.egoldmidincd.com/pont.mp3 I'm using the following plugins: exciter with 67% harmonics, (frequency 20000) flanger at 77% feedback, speed 0133HZ, intensity 95% and 81% on the mix. equalizer set to +9.5 db at 3850 Hz, and +24 at 10,000 and -24.0 db at 80.0 Hz and 10.5db at 215. I would also add the tremolo plugin if appropriate. Any comments welcome.
