There is a sort of aftertouch/velocity type effect from the mechanics of the instrument that he didn't account for which causes some modulation in the overtones. The effect can be duplicated with filters and envelopes. Since we'll never be able to duplicate the synchronization of the tones modulation (polyphonically) with straight playback, we will never be able to make a perfect "analog" (no pun intended) out of full tape loop samples anyway. I was considering taking short periods and then building on that with the SoundFont synth architecture. There is definitely a lot to work with in the samples. It's not beats, one can do more to make it nice than simple loops. Aaanyway... if you zoom in far enough there are repeating areas of flat amplitude several samples long that might be indicative of splices in the tapes or the masters from which they were cut. We won't be able to make a perfect rendition of that particular mellotron, but a good mellotron soundfont can be made out of what's there. A mellotron has actual physical loops with splices done by ear. Sweet irony. That part is a nonsensical statement without context. Here's what I did the other day when I took another pass at it (Don't wait for me to finish it): Decoded the original flac. Ditch the first 4-5 tones, they're duplicates. Cut the remainder into 3 sections, one for each timbre. Break the tones out to separate tracks/files Name 'em Normalize 'em (there's ~6db difference. Trim 'em Fade 'em if necessary If one looks at a spectragram it's pretty obvious that the whole waveform is being played (samples are long enough). The notes all start at varying places along the loops. There are issues with overtones and volume consistency over the course of the tone due to key pressure. The machine also needed lubrication or tape guide maintenance because there's at least one squeak.

Hi! First of all thanks to you all! Such a mass of replies and filled with so many interesting things. I'm sorry, I didn't reply up to now, but my access to the internet is limited nowerdays. At home I have none... Thanks for the soundfonts John, Emiliano. The idea about a textbased soundfont editing tool sound very interesting to. Get me as your second tester. :-) Three years ago I talked to Josh Green about this. We discussed the idea of textifying swami. The thoughts we came up with were close to the idea of OSC. An interactive shell, where the different layers were directories and the variables to change (properties?) were like files. Then we had thought about the set of useful commands (like cd, ls, cat or show, cp, mv, etc.) So that was that. I just thought it might be nice to throw in something, that was already thought about, perhaps it's a good one or at least it inspires. A scripting language is a very nice thing, too. Again thanks!
