What about this .krz file? I'm curious if this works for you on your Kurzweil K2500. It's 22.9 MBytes. This instrument is capable for this easy additive instrument synthesis. If you change the volume of the layers. I think there will be one problem for sure: this seems to be 16 mono layers and not 8 stereo layers. Does this mean, that a layer can only have a mono waveform on Kurzweil K2500? Please let me know your results.

Ok, i dig into it, and going to make an instrument for K2500 the weekend. What is the max filesize you can load into your K2500?

I made the first instrument with some additional subtractive dynamic settings (with "cherry on the top")... https://on.soundcloud.com/vzRt1 Kurzweil K2500 is a great synth. Can you read .kr1 files into your machine? How many waveforms (layers) can be played on simultanously (do you have 8 layers)?

Yes, and yesterday I started to put the cherry onto the top of a synthesized sound this type by adding subtractive dynamic filterings/pitches/lfos on certain layers, and it's eargasmic. I will record some of these cherried instruments too to show you some results. Btw.: do you have a multilayered subtractive synth? If you had, I might try to convert some easy additive instruments for you of this kind to try it on your own.

If we select 8 pieces from a sum of 16 elements, (don't forget, we synthesize 2 instruments = 2x8 elements/layers), there are 12870 pcs of different possible groupings of 8 different elements/layers out of these 16 layers/elements (in this case all layers/elements is on with a sound.)

Today I had 30 mins to record, how I synthesized two medieval instruments into one: The result is many new instruments again. Unfortunately it is impossible to mix and record all sounding variations, if you mix two instruments of mine, the number of possible variations are 9^8= ~ 43 millions and I recorded those only that I found interesting in this 30 mins. So here is the synthesis "mix" of a harpsichord sounds like this originally https://on.soundcloud.com/9nZ97 and a spinet sounds like this originally https://on.soundcloud.com/37MLu into these instruments: https://on.soundcloud.com/aujTm by additive synthesis on my Yamaha Motif XF.

What about a new synthesis journey with a Jupiter 8 Transisto, it is a Depeche Modish instrument a lot, though my secret garden, is not so secret anymore: https://on.soundcloud.com/A4AWw

Here is again a new instrument, a Harpsichord, ready for additive synthesis. I don't know yet what is hidden in it... https://on.soundcloud.com/KuZrM But this one is sounding...check it yourself, it's a simple portable regal organ from the 18th century: https://on.soundcloud.com/AGBXg I know what this instrument hides: e.g.: a real street organ sound.

Not a secret, but it's the know-how part. It's a complex process including Fourier analysis, spectrum analysis, preparation of additive partials and then finally creation of the instrument file itself. Since it's the know-how part, I can't give you more details, but I can tell you, that all input sound sample source go through the same process.

I'm going to make a synthesis journey with this newly built instrument tomorrow: it's inspired by a Thomas Hitchcock Spinet From 17th Century https://on.soundcloud.com/8v3qi

There is. The key here is sampling method and sampling algorithm that I call a sample preparation for this easy additive instrument synthesis.

I made an algorithm to prepare the samples. It is applied for all (the same process).

That's correct. The combination of these partials make an endless journey in sound design without entering into any subtractive lfos/filterings/effects etc... You can enter into it, since it is a wonderful thing, when a sound dynamically changes its physical parameters in a time scale, but when you enter there you've already have your SOUND, stored on your machine with you! From now I can not imagine another way to design a new sound other than that. Yes, you can do it with this method too: you can add or replace non overlapping or overlapping layers/elements in frequency at your choice. But with these instruments, you will replace, or "enrich" a frequency, or a range of frequency only, not a complete spectrum. P.s.: I think you are a clever man, (as people in this forum in general there are). It's a great thing to be a part of this forum.

Here is an additive syntnesis journey on my Yamaha Motif XF ending the sound addition with a 16th centruy Italien Clavichord instrument to check how wide this type of easy additive instrument synthesis capabilities there could be: https://on.soundcloud.com/HQtz2
